Cooling is fans only, and I have 4 WD Green, 2 WD red and two seagates (all 2G, in 2x btrfs raid 10) and a few intel and samsung SSD's (for bcache and system disks) that run ~16 hrs a day with no failures for the last few years (~10).

I may not be using backup software but if I lose the original file, I have another copy that I can back up from. Given that I have two drives that can currently hold the files I don't want to lose for sure, I have two backup copies. Whether it is called a backup or called a copy doesn't matter. All that matters is that if my drive should fail, my computer blows up, my house burns down or any number of other possibilities, I can restore the files if needed. Whether it is a technical backup or a copy ends the same way. Maybe calling it a copy is better. :-) Maybe I'm to old school. lol I will look into those software options tho. Right now I have the rsync commands to backup a few directories in a script. It's not fancy but basically one copies my camera pics, one copies my videos and the last one copies my email directory. In all honesty, if I have those three things, everything else can be reinstalled or be reconfigured. I'm not trying or even planning to copy/backup the OS itself. If something happened and I had to rebuild or redo my system, I'd do a fresh install anyway. Having the config files would be nice but only IF it wouldn't cause more problems than it solves. That was the reason for my question about using --delete on config files. I tend to backup/copy the files in /etc until I reboot then I start a new set. That way if I run into a problem, I can either use the old file in whole or take parts of it until I get whatever working again. I haven't ran into that problem in a really long time tho. I can't recall the last time I do to be honest. It's been years, many years. I'm not sure on the config files in my home directory tho. I know KDE does some weird things during some major upgrades. As for restore, easy, rsync the files back over. Even if the permissions are messed up, I can fix that easy enough. Other than that, I'm not sure what other problem I could run into. The biggest thing, having a copy I can use if I lose the originals. Also, with them being plain copies, I can take the drive to a friend or family member and plug the drive in to get to the videos, documents etc. No special software really needed. Heck, for the videos, I could watch them straight from the USB drive. Now to go check into those backup programs. Borg. Sounds Star Trekish to me, or was that Star Wars. ROFL Thanks much for the info. Dale :-) :-)

One MAJOR caveat - DO NOT let the drive fill up - a combination of snapshots and drive-full has been known (quite often) to trash the file system. But provided you make sure it doesn't go above about 80% you should be fine. You can add an option to rsync such that it will back up "in place". In other words, if only 1K is changed in a 1M file, it will overwrite that 1K. So when you back up, the procedure is to take a snapshot, then run rsync with both "in place" and "delete". This will give you the space economy of incremental backups, combined with the utility of full backups - each snapshot is a full backup as of that date, but each new snapshot only increases disk usage by the changes since the last. And you reclaim space by deleting old snapshots. > On the second enclosure I currently have a 160GB drive. It's big enough > for my camera pictures.

So no worries on that score. Plus heat causes far less problems than people think, although yes it's best avoided. Do your outbuildings have power? Do you have a fridge (or possibly freezer) out there, or could you find an excuse for one - a wine-store maybe :-) What you really want is some form of insulation that will prevent rapid fluctuations in temperature, and sticking your drives (in sealed bags) in a wine fridge would probably be near ideal. I had a cellar for my wine, and daily fluctuations were near nil even though there was a maybe 20C variation between summer and winter. That's what you want to aim for. Or maybe if you can dig a mini-cellar in one of your outbuildings :-) Cheers, Wol
[gentoo-user] The memory gremlin
[resend, list was down...] I've been meditating on the memory gremlin on my system... The ram is Corsair, 3000mhz. (never had any problem with their sticks in any system ever.) Motherboard is an early release mini-ATX B350 board from Asus... Chip is a R7 1800X The pattern is: all cells test good on memcheck but occasionally there is a bit error somewhere. I think it is a signaling issue between the ram module and the memory interface in the cpu. After meditating on it, I don't think there's anything I can do about it given the STUPID settings the BIOS goes to... The problem with the BIOS is that it considers only what the RAM tells it, it does not take into account that the CPU is rated at 2667mhz... Well there's the answer, this is AMD's first product with DDR4 support, and it's not super awesome so simply acknowledging the limitation there, and setting the memory interface to 2666 (which is what the BIOS offers), it won't be super fast but it damn well should work. =| -- Please report bounces from this address to a...@numentics.com Powers are not rights.

Whatever your choice, also look at the restore > procedure - very important. Well, a static mirror is a full backup at that point in time. If the backed up data changes little over time, it is a valid backup, which can prove its worth if/when the original drive dies, or files are deleted accidentally on the original. On the points Dale raised: The --delete option will remove from the destination any files which no longer exist on the source. So if you delete photo-1 on the source and then run rsync, photo-1 *will* be deleted from the full back up, to mirror what is currently available on the source directory. Here is where incremental/differential backup strategies can be of use, in case some time in the relatively near future you change your mind and wish you never had deleted that old photo-1. The same may apply to user config files, if you stop using an application, manually clean/delete its config files from your home and rsync --delete thereafter. If in the near future you review your position and decide you wanted that application after all and the 2 weeks you had spent configuring it would be of use again, with the --delete option your config files will be gone from the backup. So, use --delete judiciously. rsync can on its own provide you with incremental and differential backups, using hard links to the full backup directory, so as to avoid duplication and minimise storage space usage. This means that incremental backups take only a fraction of the space and additional disks or enclosures may be redundant. Take a look at the --backup, --backup-dir, and --link-dest, options. As others have posted there are a number of applications which use rsync as a back end and have scripted with config files its options. There's also quite a number of bash scripts on the interwebs offering a starting point if you prefer to hack your own. With regards to heat and humidity I suggest you take a look at the manufacturer's specifications, both for the enclosure and for the drives. Invariably environmental thresholds are printed on labels on the devices themselves, or you could google using the part numbers off them.

I've been using Duplicity in production for a few years. I find its features quite better than borgbackup. However, it has one very annoying design problem: the local cache. In my case, doing daily backups for two years for ~200GB of data requires a growing and growing local cache. It's 50GB as of now. You delete the cache and it comes back when doing the next incremental backup.

If they are networked, great, but if it relies on you physically moving hard drives between locations, it won't be done when you need it. Cloud storage is cheap these days and most backup programs have an option to store encrypted data on an external service. I'm currently using a combination of Duplicity and Hubic for this. -- Neil Bothwick How do i find the model of my card? your nick is misleading, seriously pgpNsg4q9cWQ3.pgp Description: OpenPGP digital signature

Whatever your choice, also look at the restore procedure - very important. Have a look at Dirvish or borgbackup (both in portage) for what they can do. Having a space efficient store at regular points of time is a lifesaver at times. To restore from dirvish its a copy from the selected tree. With borg its either restore with a command, or mount it and copy the data out of the mount. http://dirvish.org/ https://www.borgbackup.org/ I moved from dirvish to borg 12 months ago and they are both excellent.

Re: [gentoo-user] emerge completly a package but dont install it?
Turns out emerge has this nice flag (excerpt from emerge(1) manpage): --buildpkgonly, -B Creates binary packages for all ebuilds processed without actually merging the packages. This comes with the caveat that all build-time dependencies must already be emerged on the system.

[gentoo-user] Backup questions
Howdy, Long story short that leads up to my questions, I paid off some debt. Finally I'm getting around to doing some things I been wanting to do. One of them, backups. I bought a hard drive enclosure that has a fan to keep things cool. Figured I would get a decent one that hopefully will keep my drives working. My relevant setup. I started with a 3TB hard drive for my /home directory, one partition, years ago. I stuck LVM on it so that I could add to or move things around a bit with some ease. Once that was starting to fill up, I bought a second 3TB drive and added it to the LVM volume. So, in effect, I have a 6TB drive with 3.6TB of data on it at the moment. The biggest user of that space is videos. I just bought two external drive enclosures. One is sort of a spare but I do plan to do some backups on it, mostly pictures from my camera. In one of the enclosures I put a single 6TB drive that I found on ebay. It has about 7,000 hours on it so it should have some life left yet and it passed the smartctl tests. It is USB but it transfers fast. Now to some questions. I use rsync. Command looks something like rsync -auv /source/ /destination/. If I backup the config files in my home directory, should I also include the --delete option? If after a upgrade for example a config file is deleted, because it is no longer needed, or renamed, should the old file be removed or is there a reason to keep them on the backups? Adding the --delete option isn't a problem command wise BUT I wonder if it can cause a problem at some point. Thoughts on that. I plan to use the --delete option for videos since if I deleted one, it is likely broken or something. Biggest question is about config files. On the second enclosure I currently have a 160GB drive. It's big enough for my camera pictures. I would like to backup up my pics to it and then put the drive somewhere besides in the house. I have a couple external buildings that would be safe as far as rain etc but they are not cooled, even tho it gets close to 100F and humid, real humid, here. My question is this. Is it safe to store a drive in that sort of environment? I could see the building getting close to outside temps during the day. I do put a heater in it to prevent freezing during the winter. I usually set the heat to 40F. I'm hoping someone has some real world experience on storing in this sort of environment and not just a text book theory. One reason I want to put them elsewhere, house fire. Even a huge power strike could cause problems if plugged in. We do get lightening strikes here. Maybe not as many as some but our fair share. The 6TB and 3TB drive may join this one as well. I have a 3TB drive on the way, got a good deal on it. I plan to remove the 160GB and put the 3TB drive in the enclosure when it gets here. Later, I will get another enclosure for the 160GB drive. In the end, I will have 6TB, 3TB and a 160GB external drive. Main backups on the 6TB, possible second backup on 3TB of some important files and camera pics on the 160GB. Anyone have some real world experience on these sorts of questions? Thanks. Dale :-) :-)
[gentoo-user] libmysqlclient.so segfault
Well, after updating a while ago I noticed a new package being pulled in by mariadb - dev-db/mysql-connector-c. Ever since this update where it was pulled in (August 1) the mythtv backup script written in perl fails (mythconverg_backup.pl). It is segfaulting, and I get an email indicating so. All dmesg reports is: [29233.819979] mythconverg_bac[4703]: segfault at d26bb8ca58 ip 7f433dbc7319 sp 7ffd3ca8b160 error 4 in libmysqlclient.so.18.4.0[7f433db89000+34a000] [45297.590200] mythconverg_bac[10051]: segfault at f185283a68 ip 7f749f50c319 sp 7fff71cf09e0 error 4 in libmysqlclient.so.18.4.0[7f749f4ce000+34a000] [45818.780364] mythconverg_bac[10094]: segfault at 762032bf28 ip 7f7c3f9f0319 sp 7ffe32dfa190 error 4 in libmysqlclient.so.18.4.0[7f7c3f9b2000+34a000] I've done some poking around and rebuilt this package to no avail. Has anyone else using this found a solution? Dan

The commands to build without merging would be ebuild /usr/portage/my-package/my-ebuild-file.ebuild install This will download, unpack, build, and install the package into your temporary portage build directory (usually /var/tmp/portage). It will not resolve any dependencies though, this has to be done beforehand. The temporary install directory is called "image" in the temporary directory. You can also go through the whole process step by step, ebuild /usr/portage/my-package/my-ebuild-file.ebuild unpack ebuild /usr/portage/my-package/my-ebuild-file.ebuild compile ebuild /usr/portage/my-package/my-ebuild-file.ebuild install ebuild /usr/portage/my-package/my-ebuild-file.ebuild qmerge ebuild /usr/portage/my-package/my-ebuild-file.ebuild clean the qmerge command will install it into your system, so this is the step, that you do not want to execute ;) Cheers Andreas
[gentoo-user] emerge completly a package but dont install it?
Hi, is it possible to go through process of installing a not-installed package from source to executable ... without actually install the package - so the system as such is not touched? Cheers Meino
