All the files are basically rsyncd onto a big opensolaris filer backed with zfs. We then snapshot each hosts file system after the completed backup. It then gives us an incremental forever backup so is generally quite fast to do. Restores are also fairly fast depending on the size of the data set. For a full restore I boot into the new box on a liveusb os, partition/slice, newfs, mount and push the rsync back. All fairly easy and quick. With regard to database backups, we run all our mysql and oracle dbs on zfs. This allows us to put a global write lock on the db and flush everything to disk. We then snapshot the db zfs fs and remove the write lock. Alternatively if its a mysql slave, we just stop the slave, flush and snap. This means we can take hot backups of all our dbs with minimal impact. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

We can sit here and argue about those facts all we want (it's the equivalent of doing burn-outs in an AMC Pacer in a parking lot -- wasted time, zero gain), but nothing changes the facts. Sorry, I had to remove the whole bunch of text that you wrote :) but I get the point. I think it is a funny historical fact that BSD was commercially licensed way too long to allow Linux to be developed at first place. If BSD was not commercial at that times, Linus Torvalds probably wouldnt have started writing the Linux kernel. Thus we wouldnt be having this sort of conversation now and it might as well be that Microsoft wouldnt have become so huge. If we look at this from that point of view then eventually all BSD and Linux etc. are bound to disappear in time and Microsoft will stand all alone. But things can change one step at a time. I prefer(or try) to look at this positively. I thought it wouldnt hurt to ask for help if somebody could contact r1soft and perhaps ask a pile of money to develop a driver. It would have been a win-win situation eh? Right. We're definitely talking about snapshots, at least in concept. The fact that you're able to restore data within *minutes* is pretty impressive. I'm curious what sort of disk requirements are needed though (I guess it depends on how often changes happen on the filesystem). Well it is not so fine grained (5 to 10 minutes intervals as mentioned). http://www.r1soft.com/CDP.html (there is more information in the link above, with links to outside sources on the concept such as wikipedia articles etc.) I know some large hosters who use this technology with Linux servers. As a matter of fact the only reason they went with Linux instead of FreeBSD is because they cant get CDP with FreeBSD. I can ask how much space it is using and return back to you. But if you think about it for a second, a traditional backup program would copy the whole file even if there was 1 byte changed in it. Lets say 10mbyte file and 1 byte is changed. R1soft copies only 1 byte. Sure enough the tables can turn around if the filesystem was modified really a lot. But it looks like this type of solution is mostly effective (at least I didnt see anywhere that anybody is complaining that it is using too much disk space yet). The best is, all it would take for FreeBSD users to be able to utilize this technology is a driver to interface with r1soft agent and buy a license. Now I am not expecting anybody to write this for free or nobody is obligated to help. I just dont know anybody who can help so I thought I would drop in a line here so... I for one have never correlated snapshots and backup restorations (bare-metal recovery). I consider them completely separate things, and handled *very* differently. I have a feeling that no one's done this on FreeBSD because the amount of effort required is quite large. Someone did mention HAMMER on DragonflyBSD, but I have no knowledge of it or what it provides -- that said, Matt (Dillon)'s stuff is usually very, very good. I also dont know much about HAMMER either. But it doesnt look like it will make mainstream usage anytime soon on FreeBSD if it ever does. Actually I found a nice document here: http://www.dragonflybsd.org/hammer/hammer.pdf http://www.dragonflybsd.org/hammer/index.shtml It depends on how the filesystem is done. For example, with UFS2+SU snapshots, snapshot generation can take literally hours: completely unreasonable. While with ZFS, snapshot generation usually takes 2-3 seconds -- even on massive changes (e.g. take a snapshot, then rm a 600MB ISO image, then compare present vs. snapshot -- the diff is something like 40KBytes). Yes, but r1soft backup can restore a single file at a consistent state without restoring the whole filesystem from a graphical user interface and can restore mysql databases at a table level. While I agree that there might be different solutions that I dont know about, it just takes a driver to get this functionality on current FreeBSD systems without everybody to change to ZFS or HAMMER. One has to think, would people change their filesystems or install a driver? :) I would rather pay license fee to a backup program and use the driver. The price of the software is very well justified if I can return back to 5min before in my backups. The data I might loose is much more expensive. I'm sorry for sounding anti-FreeBSD, but the reality is that people should use whatever solutions work best for them -- if that's using Windows, Solaris, or Linux, great! Remember that open-source is about choice: and choice means supporting the possibility that someone chooses something else.

Re: continuous backup solution for freebsd?
Sorry for once more but: you can make incremental backups every x minutes with Bacula too .. it only takes one or two minutes on my box to scan for changed files for ~150GB (even faster if you tweak it a bit). It's not really a "true" continuous backup solution, but it's perfectly possible to restore directories/files for changes which occurred x minutes ago, and with retention periods of x days/months/years.

I see it happen, it's bizarre -- suddenly out of no where comes this one fellow (we'll call him Bob), appearing on a mailing list with a bunch of patches. Heard of him before? Nope, but here he is, and somehow he engineered all of this. What's his background? I don't know, maybe some old guy who lives in a cave and has been studying BSD code in the steam tunnels; who knows. It's like they literally come out of the woodwork, while I don't see this sort of behaviour with Linux. With Linux, it's often "Hi I work for , we're adding support for Linux, I need some help with regards to the following kernel piece..." and they've got responses from 20 people in 24 hours. What I'm saying is that Linux has the upper hand here. More eyes, more people, more developers, larger community, larger vendor support, and much **much** faster turn-around time on fixes/bugs.

What you're talking about sounds like filesystem snapshots, with an *immense* amount of granularity. Enterprise-level filers have this capability (I'm talking Network Appliance), and UFS2 with softupdates have it (called snapshots; but please be aware that there are *HUGE* problems with it, and it should not be relied upon for this kind of functionality) -- but nothing that can be restored within *minutes*. Even Netapp filers do not have that kind of granularity -- the amount of disk it would require would be astounding. Netapp filers often do snapshot generation hourly or nightly (it's configurable how often); minutes is unheard of. ZFS also has snapshot capability, but does not have real-time filesystem mirroring capabilities over a network (keyword: real-time). > Besides, I hear geom might > have network delay problems and it is much more complicated setup to > build two machines in mirror configuration just for backup purposes as > well as you cant restore to a point in the past.

Re: continuous backup solution for freebsd?
First of all, I am not an r1soft advocate, but they seem to be making a software which is popular and affordable and interested in giving FreeBSD support... r1soft is not the issue here, the problem is that there is no way to do near continuous backups on FreeBSD servers. Jeremy Chadwick wrote: That said, I'd like to know exactly how "low-level" R1Soft's software truly is. dump(8), AFAIK, is "block-level" -- and that's a userland program. Does R1Soft's software *truly* require kernel-land? I have more to say on that issue (not against R1Soft, but speaking with regards to the current state of FreeBSD's developer count) if it truly does. I think you might not have understood the concept of near continuous backups. The R1Soft backup monitors the filesystem operations and backs up written blocks. So it has to know what is written and when to be able to back it up. The dump command simply reads/writes the blocks. It cant only read changed blocks. It has to read the whole thing (inefficient). Continuous backups as well as bare-metal-restore seem to be a key feature for many hosters. Regarding continuous backups: the GEOM gate class could be used for this. Meaning, I think it could be used as an alternate to R1Soft's software. The GEOM gate allows mirroring to a remote machine, am I not right? That would be more or less same as same as using RAID. The continuous backup (or near continuous) means that you can restore the filesystem to a point like 15 minutes ago, or 1 hour ago. Besides, I hear geom might have network delay problems and it is much more complicated setup to build two machines in mirror configuration just for backup purposes as well as you cant restore to a point in the past. Regarding bare-metal restoration I'm not aware of how to do that under FreeBSD, Linux, or even Solaris "with ease". In most cases, companies develop their own PXE-booting environments which wipe the disks and reinstall + restore data as they see fit. There is no "standard". OK. Actually there is more than one solution which can do bare-metal-restores for FreeBSD also. However those solutions at best rely on nightly backups of the filesystems. With R1Soft, you can restore the system to only few minutes before the total meltdown. Unrelated to bare metal restore, with normal backups you are not taking backups of files which are created/deleted often. For example this can be customer mails or if a hacker hacks the box and removes his trails. Even sometimes customers upload some file and remove from their computer the same they and then accidentally remove from the server. With R1Soft backup the data would go into the backup server right away and you an restore every single file independent of when it was put or removed. FreeBSD is loosing users because of this issue. Why does the "number of FreeBSD users" matter? Quantity does not necessarily represent quality. Thats a perfectly fine statement. But a quality product would be nothing without users. As well as this problem effects the quality. Consider a system which has sensitive data which shouldnt get lost, with continuous data protecton you can restore such failed system to only few minutes before the failure point. Doing this is currently impossible with FreeBSD. Best we can do is to return to previous snapshot taken (which might be a day old). This is an important design criteria since restoring the lost data might be time consuming and expensive. Thge issue is not even r1soft, they are just the most popular company giving such solution, only if there was at least one backup solution which could provide near continuous data protection... In addition to this, near continuous backups create less load on boxes with a lot of reads but little writes. Standart backups have to scan all the files to detect which files were changed. I'm sorry for sounding anti-FreeBSD, but the reality is that people should use whatever solutions work best for them -- if that's using Windows, Solaris, or Linux, great! Remember that open-source is about choice: and choice means supporting the possibility that someone chooses something else. Blind one-sided advocacy is very damaging to the open-source model and concept. I agree, and please dont shoot the messenger :) I just have a bunch of customers who would use FreeBSD but not using only because of this problem. In addition to that I myself would like to use near continuous backups as well. I was just trying to inform the FreeBSD community here so if somebody can have some time to divert to giving the right advices to r1soft then we all could benefit from it. It doesnt even have to be free even, with a reasonable price they can probably hire somebody to work for building the basics of this feature. So the real question is,

First and foremost, the URL you gave is terse and out of context. Let people read the entire thread: http://forum.r1soft.com/showthread.php?p=3414 So let me throw around some ideas. First and foremost, David appears to be saying "We'll take FreeBSD seriously if we can get proper documentation, and it needs to be thorough, that explains how to interface with devices on a block level so we can perform block-level backups and write our software appropriately". AFAIK we don't have any documentation that outlines that in a clear, concise manner. With regards to "providing protocol documentation and letting the open-source community write the software", R1Soft is generally right. Time and resources are the biggest problem with open-source; do not think for a moment that just because millions of users can look at source code means they understand it, or even know how to write it, or will even *want* to. The majority do/will not. That said, I'd like to know exactly how "low-level" R1Soft's software truly is. dump(8), AFAIK, is "block-level" -- and that's a userland program. Does R1Soft's software *truly* require kernel-land? I have more to say on that issue (not against R1Soft, but speaking with regards to the current state of FreeBSD's developer count) if it truly does. I'm somewhat surprised that their software focuses on Linux and Windows and not Solaris and Linux, especially given that they're interested in "dedicated server markets". Solaris is always the first OS that comes to my mind when talking about hardcore server operating systems. > Continuous backups as well as bare-metal-restore seem to be a key > feature for many hosters. Regarding continuous backups: the GEOM gate class could be used for this. Meaning, I think it could be used as an alternate to R1Soft's software. Regarding bare-metal restoration I'm not aware of how to do that under FreeBSD, Linux, or even Solaris "with ease". In most cases, companies develop their own PXE-booting environments which wipe the disks and reinstall + restore data as they see fit. There is no "standard". > FreeBSD is loosing users because of this issue. Why does the "number of FreeBSD users" matter? Quantity does not necessarily represent quality.

It has to scan all the files to find new/changed files to backup. The r1soft agent monitors file system writes and backs up changed parts immediately. This does allow r1soft backup to restore the system to its latest state (10-15minutes ago state, thus continuous backup is achieved) as it continually updates the backups. Also has much less stress on the systems where the writes are not so much since it doesnt have to check every file at each backup cycle. Also r1soft cdp has support for MySQL where you can easily restore mysql data in table level if required. It is as well supported by a wide variety of web hosting automation systems for example H-Sphere ( http://www.parallels.com/hsphere/ ) etc. through plugins. Please see the info about continuous data protection: http://en.wikipedia.org/wiki/Continuous_Data_Protection Otherwise I am currently using BackupPC (which is pretty good in my opinion and easier to use compared to Bacula) to take nightly backups of the servers.

You are stuck with some kind of real time mirroring then. There is no backup solution that doesn't have at least a little lag. There are also socalled 'bare-metal' solutions such as Acronis, but in some sense, they are also a form of mirror/softupdate/journaling that may cost you possibly more than you want - given what you say above and are still vulnerable to a physical disk failure without additional backup and if you have to revert to one of those backups, then you have that lag loss. A mirror of a checksumming raid with periodic backups is probably the best you can get without getting in to huge money. The only question is your backup media. Tape is the old standby and still works, but takes a long time. Additional large disks are becoming popular because they are fast and easy but can get expensive when the dump takes more than one for a full dump. jerry > > So many experts here in this mailing lists can suggest their techniques > for a full system recovery(& backup solutions) after the crash without any > data lose. > > Your kind responses will help me lot > Thanks in advance > KK > > _ > Post free property ads on Yello Classifieds now! www.yello.in > http://ss1.richmedia.in/recurl.asp?pid=220 > > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Seriously. If your data is that important, put it in a loop and run it nonstop, or with a 5-minute sleep between each run. In general, however, the requirements you seem to be asking for don't fall under the category of "cheap".

Backup Solution
Hello everyone, I am relatively new to the FreeBSD game and have a bit of a problem which I am not sure how to tackle. I recently build a server running VMWare ESX Server 3 which will eventually run 6-7 small production VM's. These Virtual Machines obviously have the need for backups and it poses quite a problem for me unless I connect 6-7 external tape drives and give each VM it's own tape device. I have looked into a few solutions using VM products (consolidated backup) but it can only be done if you utilise a SAN. The server is running RAID 5 with around 700GB of space. Each VM may take up to 50GB and backups might be around 15-20GB per VM. The machine itself has an internal LTO3 tape drive, has anyone come across this kind of situation before, and if so what would be a good way to backup each VM? It is easy enough to backup the image files from the host machine but I need file level backups within each VM also. I will be very grateful for suggestions or ways people have tackled this kind of problem in a production environment. Thanks.

Re: backup solution for home FreeBSD server

I used to use DLT tapes, and I looked at AIT before I decided on disks. The disks have a couple of advantages that would be hard to match with tape. One is that the backups are completely unattended; I have two USB drives plugged in at a time, and some little scripts wake up each night, figure out which disk has the least recent backups, delete enough old stuff to make room for a new backup, and then use pax -r -w to make the backup from each of the computers on my LAN. The only manual work I need to do is to swap a drive with the one in my safe deposit box once a week. Also, since they're disks, getting files back from a backup is a snap, just cp them from the most recent backup copy. The three disks together cost under $500, and if I need more backup space, I can just buy some more larger ones. To get approximately the same unattended backups I have with my USB disks I would need an AIT jukebox for about $4000. Getting files back would be much more painful, since I would have to spin through an entire dump or cpio image to find a file. Tapes make sense if you have a vast amount of data, multiple terabytes. You need a lot of terabytes before the cheaper media makes up for the much more expensive drives, and it's still nowhere near as convenient as disks.

LTO is pretty fast, though it doesn't seem to have the fast search that was about the only thing I liked about DAT/DDS tape. But the cost of LTO for a home system is hard to swallow. You could get about a dozen USB drives to rotate for a similar cost. Tapes are nice for archiving or long term storage though.

I know it's probably not so active, but it seems a lot more powerful, and it supports MH (working on getting the Maildir plugin to compile properly). It (sylpheed-claws) reminds me of good old XFMail, which I had used for a long while before Thunderb. FWIW, I have 9 email accounts (a few with different identities). Work related email is from an Exchange server - I tried Evolution + its exchange plugin and it just wouldnt work, so I moved on. Anyway, Work's IMAP cache is a symlink to a subdir in my GELI disk (this is a laptop after all). Work's local copies are also in the GELI disk. For backing up on the client side, I simply rsync to another box my ~/.sylpheed-claws, my GELI md device and the tar ball of the local copy my non-work emails (faster than transferring thousands of individual mails - MH format...). This is part of my laptop backup script (could be using dump, but i only need a small portion of the filesystem... setting nodump in most of the box is rather silly) > Or have I failed to understand something? maybe u should start by reading the config file and following through with each path mentioned,etc... it worked for me (tm) for Thunderbird, (FFox) and sylpheed good luck, Beto ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Sure: /usr/ports/mail/offlineimap But there's one caveat though! offlineimap does a symmetric synchronization between both sides. If you play around with your local copy, and delete some messages there, offlinemap will also delete the corresponding messages on your ISPs IMAP server (unless you delete the metadata before), which may not exactly be what you want. I've been there the first time and I've been bitten by this once... but I'm using this now for regular backups and sychronizations between multiple IMAP hosts, both mobile and fixed.

The two most common styles of mailboxes are mbox and maildir, and both of those can be backed up at the filesystem level using dump, tar, or anything else.

Your mail hosting provider should have working backups, although it is worth checking. Anyway, if you use IMAP to download the mailboxes, your locally cached copy of that information on a client machine could be backed up as well. It's not as useful as backing things up at the server side, but it would ensure that you still have copies of the important mail. Otherwise, simply export your mailboxes to a mbox file once a week or once a month or so and archive that separately. -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Since we have no idea *why* you consider tar ideal, we can't really tell what would help your particular needs. On my page of FreeBSD tricks (http://be-well.ilk.org/~lowell/systuff/), I have a brief essay on what to consider when designing a backup strategy (http://be-well.ilk.org/~lowell/systuff/backup-strategy.txt), as well as some script I use for backups via both tar and dump (http://be-well.ilk.org/~lowell/systuff/scripts/systemTarBackup and http://be-well.ilk.org/~lowell/systuff/scripts/systemDumpBackup).

5.3 backup solution needed (non-SCSI)
I finally found the reason my 5.3 machine was randomly rebooting. It is either the scsi HBA and/or the drive. Although the same exact hardware runs any other OS fine :-/ well with that in mind, I am now all IDE and USB capable. No more SCSIso there went my tape backup solution. I need to backup only about 4-5GB at once. My DDS SCSI drive handled that fine... Does anyone know of an IDE based solution -or- a USB backup solution? This is a 1U rack server, so if I used IDE based, I would have to open the machine and jury rigg it any time I needed to backup. I have dual standard USB ports though, on the front of the server. Any ideas will be appreciated ! -JEFF ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Tape backup solution? [OT]
Hello List, I have a question that's slightly off-topic, but not. I install high-end surveillance equipment for CCTV and such. I have a rather large client in Minneapolis who's using Dedicated Micros digital video recorders. The particular model we're using has a 500 GB hdd, but this client would like to archive images to tape for longer storage. As of now, we're only getting about 2 months of recording time. For off-site viewing, this unit can off-load images to a SCSI cd recorder. Does anyone suggest a tape backup device that would be SCSI and external, with a fairly high-capacity? I'm thinking around 50 GB?

First, it's actually a Linux system, though there's nothing particularly Linux-specific about it except the device names and the method of spinning down the backup disk after the job. The cornerstone of the solution is the rdiff-backup program (http://rdiff-backup.stanford.edu/ or in ports at /sysutils/rdiff-backup). rdiff-backup is a python script that mirrors one directory to another. It can do incremental backups and it can do them either locally or remotely. It's really a slick piece of software and I'm continually surprised that it doesn't get more publicity. First, there's the (trivial) script /usr/local/sbin/backup-share.sh. This is run by a daily cron job to backup directories on the disk that contain Important Data. Mine is very specific to my system. It is *not* pretty and I plan to overhaul it sometime soon to include error handling and an external config file. #!/bin/bash # script to automatically back up the important stuff on /nfs/share prog=/usr/local/bin/rdiff-backup src=/nfs/share dst=/backup/share budirs="code emu images media music school software text webpage" mount /backup for dir in $budirs do $prog $src/$dir $dst/$dir done umount /backup # put backup drive in sleep mode since we won't be needing # it again for the next 24 hours or so hdparm -qY /dev/hdd A note about the last line: it appears that FreeBSD can only spin-down SCSI disks on command. (See camcontrol(8).) The best way to power down IDE disks seems to be just setting a suspend timeout in the power management section of your BIOS. Once the disk is unmounted, FreeBSD won't touch it thereafter and the system should put it in suspend mode automatically. The crontab entry looks like this: # backup selected dirs in /nfs/share @ 0730 daily 30 07 * * * sh /usr/local/sbin/backup-share.sh That's really about it. Like I said before, moving the backup disk to a separate machine would be trivial. If there are any questions, I'd be glad to answer them.

This solution sounds nice, I can even imagine setting up an additional machine (on the same location though) to have a somewhat galvanic isolation between the disks. Only fire, earthquake and a neutronbomb would affect such a backup solution. However, I could use a push in the right direction when it comes to how to configure and what software to use for achieving the incremental backup tasks.

good mass storage backup solution
I have been using tapes for yeares, both DDS/dat and AIT style units. This seems the be cheapest solution for high volume backup. But I'm wondering if anyone has any hardware solution that is really a good backup media. I used ORB disks for a while, at 40$ per 2gig disk of DASD style media I thought it was okay (more expensive than tape but I liked direct access style media) Any votes for DASD style systems? Sequential media is still kind of a pain in the rear so I'm looking for suggestions of new/good/innovative technology. tx -- David Bear phone: 480-965-8257 fax:480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
