[BackupPC-users] One PC Very Slow to Backup
Still doing some testing. Not sure of the cause but one thing I do know is that I did a incremental and a full backup from the command line and both of these were done in the normal time of a bit over 2 hours. Will see how it goes When monitoring the bandwidth of data that is transferred from my PC should I get approximately the whole volume of the share in data traffic being sent from the PC being backed up. It seems odd that this PC is doing this. For both incremental and full it is transferring approx 7.5GB of data over the network. I thought that it was meant to be a relatively conservative with data traffic after the initial backup. Not that this bothers me too much but just trying to look at all possibilities as to the problem. My other PC's including a linux file server dont exhibit this same behaviour (at least for the incrementals). Thanks all for your assistance to date. I will be in touch in the next few days to let you know how things have gone. And no this is not related to antivirus (dont believe in it on desktop pc's in my environment but thats another story) and no firewalls to worry about either as they are fully disabled for internal data traffic. +-- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +-- - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

It's like a copy tool that only transfers the changes and it can work both locally and over network connections. It is a command line tool though. I don't know what OS you're running, but there are also some rsync GUI frondends out there I believe. BackupPC also supports rsync as a backend, but it might be overkill for just backing up a single machine. Also take a look at rdiff-backup if you want to keep multiple versions of files. BackupPC also supports rsync as a backend, but setting up a BackupPC server for just one machine might be overkill maybe. It will work though and its web interface is very handy for restoring files.

Re: [BackupPC-users] free backup software
I use Cobian on a lot of machines here. Most often, I have it back up to a Winzip archive. In this case, my restore function is the WinZip program. It doesn't seem to handle compression of large backups that well. For those, I simply back up the files without compressing them. In this case, my restore function is Windows Explorer. The new folders are most likely Winzip archives. You can set the number of backups you want kept in the software. Cobian also has excellent support, considering its free. You go to the Cobian message board, and Cobian himself comes on there every couple days. I personally don't know how he finds the time for all this. The key fact is that he does.

Re: [BackupPC-users] migrated backuppc server from linux-solaris Size/MB=0
I had that problem once and I think it came down to a permissions issue.

I did the following on 192.168.1.2 : - stop all firewall and protection - allow root to connect by ssh Please verify that backuppc can 'ssh -l root' without password prompt. The rsync command I gave you above does that, but once more: you need to run it as the backuppc user.

Re: [BackupPC-users] free backup software
Hello, I haven't tried Cobian (but thank you for mentioning it). To make backups on a local client without setting up a server and with the possibility to browse the backup archives using an GUI, I used Areca Backup: http://areca.sourceforge.net/ It's open source, has a nice built in browser to look at your archives, does compression and encryption and does offer other features like email-summarys, merge of archives etc. While not OpenSource you might also be interested in SyncBackSE http://www.2brightsparks.com/syncback/sbse.html But as mentioned by someone else, this is somewhat offtopic. If you want to enjoy this helpful community, I guess you 'have to' install BackupPC (maybe in a virtual machine?) :-) I've tried several backup-programs that had to be installed on desktop-pcs to make backups to an external harddrive and it was always a pain. Not only you have lots of configuration, but its much more complicated to view the logs and get a picture if all clients have been backed up etc. So _if_ you have more than one pc, you might want to check out BackupPC - my first BackupPC-Server was a Pentium III with 800 Mhz and 512 MB RAM.

Will see how it goes that's great, so you have a backup in case you mess everything up - but it sounds strange that an incremental backup needs the same time like the full backup. Have you tried to make some more incremental backups? I'm a BackupPC nOOb and I made the mistake of leaving the '+' after the newer than variable while I was doing a backup of a local machine. This confused BackupPC (not suprsingly) and it interpreted the date as some time in 1901 so my incremental backup was the same size and took the same time as the full backup. In the log file, check the 'newer-than' date on your incremental backup. From what I remember of this thread I don't think that this is your problem but you never know.

[BackupPC-users] Just to make sure: How to move/copy /var/lib/backuppc to another place (RAID1)
Hello, after getting so much interesting ideas how to backup the backuppc-server after asking this questions two weeks ago, I'm now close to take action. The topic was: Prepare for the worst, Howto backup the backuppc-server To summarize: I want to put /var/lib/backuppc on a RAID1 and add one (two) external disk to the RAID. Since this raid can be removed from the raid after the content has been synced I have a full copy of the backuppc-data for secure offline storage. Another idea I want to try afterwards is to add a disk using AoE (ATA over Ethernet). Because the AoE-Disk is attached to a virtual machine running on a client, I don't even need physical access to the server room, when swapping the drive for offline storage. Since I've also an dd-diskimage of the server stored on the raid, I should be able to rebuilt my server (and then all clients) very easy (in theory). My RAID1 (/dev/md0) is now mounted at /mnt/md0 and as far as I understand I need to move /var/lib/backuppc to the RAID. Then when finished I would remount the RAID to /var/lib/backuppc. Question While looking for information about how to move the /var/lib/backuppc-directory I found: 'change archive directory' on the backuppc wiki http://backuppc.wiki.sourceforge.net/change+archive+directory Option 1 suggest to use: cp -pR /var/lib/backuppc /mnt/md0 while Option 3 suggest to move the directory to another place. In order to be safe when something bad happens while transferring the data to the RAID, I dont want to use 'move'. Just to make sure that I don't do something stupid before copying tons of GB of backup-data I would like have a short feedback regarding the command in option 1. Will this do the job? Can I just remount my RAID to /var/lib/backuppc afterwards and be sure that everything is working?

[BackupPC-users] Problems excluding files.
The documentation for $Conf{TarClientCmd} says
...
Also, you will probably want to add ``/proc'' to
$Conf{BackupFilesExclude}.
The following variables are substituted at run-time:
...
$fileListspecific files to backup or exclude
...
I took this to mean that $fileList takes care of excluding the files in
$Conf{BackupFilesExclude}.
I have the following in my host.pl file:
$Conf{BackupFilesExclude} = {
'system' = [
'/proc',
'/sys',
'/tmp'
],
'backup' = [
'/media'
]
};
but the log show that it is still trying to backup /sys and /proc.

No.
You need to use the share name as hash key. Since you're using XferMethod
tar, chances are your share is /, so you'd have
$Conf{BackupFilesExclude} = {
'/' = [
'/proc',
'/sys',
'/tmp'
],
'/whatever/share/you/mean/by/backup' = [
'/media'
]
};
You *can* use '*' as hash key if you want the excludes to apply to every share
not explicitly given an exclude list, but it seems better practise (and less
error prone) to explicitly list excludes by share like you did.

Holger

Aahh!!! Thanks Holger.
I had not understood the use of the hash key. I thought it was just a
kind of group name for some excludes.
Now everything is working as expected.

Just suppose *that* gets interrupted part way through ...] Just to make sure that I don't do something stupid before copying tons of GB of backup-data I would like have a short feedback regarding the command in option 1. Will this do the job? It is *guaranteed* not to. Whoever put that in the wiki either does not have the slightest clue what he is writing about, or he is talking about an empty pool (read: BackupPC was freshly installed and *no backups done*) and didn't make that unmisunderstandably clear. Even the potentially correct 'cp -dpR ...' will not work in the general case. The command from the wiki does *not* preserve hard links. Your pool will explode to at least twice the size, and that's assuming every pooled file is only used once (which would practically mean you've only got one backup). If you've got the space, you *could* get away with it, because future backups would be pooled, but for current backups, the benefits of pooling would be forever lost. The next run of BackupPC_nightly would empty the pool (so you might as well not copy it in the first place), and the files would need to be re-compressed during future backups. So: while it is conceivable that someone might use this as a last resort, you don't want to migrate your pool like this. The version that *does* preserve hard links (cp -d option) will work for structures upto a certain limited size. There seem to be people on the list who repeatedly insist that it worked for them, so it will work for you (despite the thread already containing an explanation to the contrary). Apparently it has even made it into the wiki. On the other hand, there have also been countless reports of problems with *any* file-based copying of the BackupPC pool using general-purpose tools - cp, rsync, and tar spring to mind. They either run out of memory or take long (read: days to weeks, meaning they are usually aborted at some point; I'm not sure if they would eventually finish). This is, basically, due to the fact that you cannot create a hard link to an inode based on the inode number. You need a path name, i.e. a name of the file to link to. For a few hundred files with a link count of more than one, it's no problem to store the information in memory (and that is what general-purpose tools are probably expecting). For 100 million files with more than one link, that obviously won't work any more. Add to that the delays of chaotically seeking from one end of the pool disk to the other (the kernel needs to look up the paths you're linking to, and there's not much chance of finding anything in the cache ...), and you'll get an idea of where the problem is. Lots of memory will help, preferably enough to fit the pool into cache altogether ;-). Your best options remain to either do a block level copy of the file system (dd) or to start over. You can, of course, *try* cp/rsync/tar and hope your pool is small enough (hint: count your pool files). I'm not saying it never works, only to be aware of what you're facing. Remember, for cp you need -d, for rsync -H and for dd a destination partition at least as big as the source file system. I haven't heard reports of problems with file system resizers and BackupPC pools, but I'd be cautious just the same. Can I just remount my RAID to /var/lib/backuppc afterwards and be sure that everything is working? If anyone has good ideas how to *test* the result of copying a pool, I'd also be interested (and please don't suggest 'diff -r'). I can imagine a lot of things going wrong that BackupPC would *not* notice.

[BackupPC-users] move a specific backup (share) from one pool to another pool
Is it possible to move all of the backups and incrementals of a particular share (/home/user) from one data directory (pool) into another? Let's say I've got 100 home directory shares that use up 16TB of data in one top level directory (pool). I cannot expand this volume beyond 16TB but I can get another 16TB volume. Is it possible to extract the backup data for a particular share from one top level data directory (pool) and move it to another top level data directory (pool) on another file system? If each of the home directories were equivalent in the amount of space used, then I could move 50 of the backed up shares to the other volume and then spread the original 16TB across two 16TB volumes (leaving 8TB on both volumes). +-- |This was sent by [EMAIL PROTECTED] via Backup Central. |Forward SPAM to [EMAIL PROTECTED] +-- - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

Hi, sabujp wrote on 2008-08-04 23:18:41 -0400 [[BackupPC-users] clustered file system and multiple servers]: Can a dev let me know if the files in the pool are FLOCK'd before writing, use the force, read the source. grep -r flock backuppc-3.1.0 suggests that flock is used, but not on pool files. Not surprising, considering BackupPC_link and BackupPC_nightly (or two instances of BackupPC_link) may not run concurrently (BackupPC_link is responsible for entering new files into the pool). Come to think of it, the reason for this restriction is of a different nature: BackupPC_nightly sometimes needs to rename pool files (with a common BackupPC hash, when one or more files out of the chain are deleted), while BackupPC_link may insert a new file with the same BackupPC hash. You can't prevent the resulting race condition with flock() - at least you don't effectively change anything in the single-threaded case (you'd need a rather global lock). i.e. is there a chance that two servers backing up into the same top level data directory could mangle a file in the pool in this manner? I don't think you'd have mixed file contents (or, effectively, a corrupt compressed file), but there seems to be a chance of linking a file in a backup to the wrong pool file (wrong contents altogether). You could probably use flock() to prevent two instances of BackupPC_link/BackupPC_nightly running simultaneously on different servers, but there are more things you would want to think about (running BackupPC_nightly on more than one server does not make much sense, even if they don't run concurrently; limiting simultaneous backups over all servers; ensuring BackupPC_dump is not run twice simultaneously for the same host ...). In short: sharing a pool between servers is currently not supported.
