- ell0bo, on 07/18/2008, -2/+36Quick, simple, and a quality read. Finally some useful tech on digg again.
- chr00t, on 07/18/2008, -1/+33RSync over SSH is the *****!
- censorshipwreck, on 07/18/2008, -0/+26Agreed, I miss the tech.
- hogfoot, on 07/18/2008, -0/+18sftp runs over ssh
- Totz83, on 07/18/2008, -0/+13Thank God Batman isn't involved in this
- caldaan, on 07/18/2008, -0/+12Just as a tip, typically cron doesn't run with the same default environment variables as a normal user would. You normally have to use full paths or import settings into the script.
- chr00t, on 07/18/2008, -0/+11Or just use scp....
- brettalton, on 07/18/2008, -0/+9Easy there duplicate: http://digg.com/linux_unix/Automate_backups_on_Lin ... -- 661 diggs too. Not hard to find.

- ironiridis, on 07/18/2008, -0/+9.... who cares?
- Acglaphotis, on 07/18/2008, -1/+9fark.com is that way ---->
- mudpuddle, on 07/18/2008, -2/+10I used this great guide to make automated, incremental, encrypted backups to Amazon's S3 services:
http://www.brainonfire.net/2007/08/11/remote-encry ... - bradleyland, on 07/18/2008, -0/+7RAID is not a backup, it's redundancy. A redundant set of corrupt data is as useless as no backup at all.
- Elranzer, on 07/18/2008, -0/+7Please proceed to /dev/null
- LiberalsSuckAss, on 07/18/2008, -0/+6Why anyone would digg down mudpuddle's link, I'll never know.
Automated incremental compressed and encrypted backups to S3? That's the best of ALL worlds!
Thanks for the link, puddle. - Acglaphotis, on 07/18/2008, -0/+6ssshhh, just smile and nod.
- MikeFromAmerica, on 07/18/2008, -1/+6Your precious RAID won't save you when your house burns down. Or when you accidentally delete a file.
- trogdoor, on 07/18/2008, -1/+6cinder And my building hundreds of miles away happens to burn down at the exact same time?
I don't think that any backup solution will protect against Armageddon. - Colindean, on 07/18/2008, -1/+6rdiff-backup encompasses just about everything, plus differencing.
http://www.nongnu.org/rdiff-backup/
sudo apt-get install rdiff-backup - mudpuddle, on 07/18/2008, -0/+5They're passionate about not backing up
- dmourati, on 07/18/2008, -0/+5Simple is good.
- Elranzer, on 07/18/2008, -0/+4I'd rather have a shiny, pretty GUI-based backup solution that doesn't really work and requires expensive additional hardware in addition to my proprietary hardware/OS system to not work...as in Time Machine.
- rxbudian, on 07/18/2008, -0/+4I almost laughed at that statement... but I think general users don't see very many alternatives to the common solutions
- Elranzer, on 07/18/2008, -0/+4/sarcasm (I hope)
- Elranzer, on 07/18/2008, -0/+4Batman is the new iPhone 2.0 is the new Barack Obama is the new Ron Paul is the new iPhone 1.0
- vibrokatana, on 07/18/2008, -0/+3The one thing that sets me off about rdiff-backup is that it is new enough where the versions in the ubuntu repo are incompatible with the ones on the fedora/centos side. Also it doesn't seem to retain some of the meta information, which lead to a rather fun time disabling SELinux just to boot the system. No fun at all.
Now I do localize tarball differentials and rsync offsite. - RajAtWork, on 07/18/2008, -0/+3as far as saving files elsewhere, it is so simple on Linux - it is not even funny.
But what about backups suitable for bare-metal recovery?
I have my Mythtv machine (client) crap out on me several times and re-installing it with all the local settings (local myth directories, mount points, installed software, etc.) has been pain. - serwin88, on 07/18/2008, -3/+6Dugg for making backing up porn a breeze...
- Black6x, on 07/19/2008, -0/+2$10 says that if you put that as a title, it will hit the front page.
- solarwind24, on 07/18/2008, -0/+2This isn't a surprise coming from IBM. They always have produced high quality articles and have always contributed to the open source movement. Their tech writers actually know what they're talking about.
- darthchaosrspw, on 07/18/2008, -0/+2I use Remastersys to back up my Linux installations. Makes it real convenient when you install TONS of stuff and want to back up all that stuff to a DVD.
http://www.remastersys.klikit-linux.com/ - div2n, on 07/18/2008, -0/+2I haven't tried it, but you can allegedly do bare-metal recovery with Bacula.
- LiberalsSuckAss, on 07/18/2008, -0/+1I don't like Jungle disk because it maxxes out at 5 gigs (a limitation of S3) and I've got mail files that are much larger than that.
- chroko, on 07/18/2008, -0/+1Your precious backup warehouse on the moon won't save you when the sun goes supernova.
- cactus476, on 07/18/2008, -0/+1I love IBM tuts!
- 3leggedHorse, on 07/18/2008, -0/+1This is pretty handy if you use ubuntu.
http://ubuntuforums.org/showthread.php?t=35087 - inactive, on 07/18/2008, -0/+1check out backuppc
its great - whereisian, on 07/18/2008, -0/+1$man crontab
- bradleyland, on 07/18/2008, -0/+1Once you have a stable build, use dd to image the entire drive, then use standard backups to get all your config and data stuff on a daily basis.
- super_spyder, on 07/18/2008, -0/+1I have been trying to figure out an easy way to clone my devian server's boot disk to a second disk on a daily basis, kind of like how superduper on the mac.
- MattBD, on 07/19/2008, -0/+1Also very handy for other purposes. You can use it to roll your own distro (PC/OS uses it), and I have used it to create a backup CD so I can take my Ubuntu install anywhere. and have the same desktop, bookmarks etc on any computer.
- marksands07, on 07/19/2008, -0/+1@leamanc I just specified the " p -22 " in case anyone wanted to copy this and uses a different port rather than asking "how can i run the command using port 222 " for instance. And yes I also run mine in a script with tar rsync and ssh, all those goodies.
- darthchaosrspw, on 07/24/2008, -0/+1Well I did use Remastersys to make gOS Ultimate E (might make a new one to include Firefox 3.0.1 downloaded using Ubuntuzilla) and Xubuntu Xtreme (8.04.1 and 7.10.1).
- LiberalsSuckAss, on 07/18/2008, -0/+1Bare metal backups are always scary to me. Often you have to nuke your working copy to see if your backups work (if you only have one set of hardware).
On Linux, I rsync the whole filesystem (minus the /dev /tmp and other voodoo stuff) and then just do a system reinstall from distribution disks. Then, I overwrite the base install with my backup. It's worked for me in the past for a quick and dirty disaster recovery. - cinder, on 07/18/2008, -0/+1trogdoor: I was in no way implying that both locations would burn down at the same time. Mike's initial argument wasn't very solid, and I was pointing that out. But I guess the article *is* about network backups.
- Fartag, on 07/18/2008, -0/+1I like backup2l (that's a lowercase 'L' on the tail end), it does N-level (you pick the N) hierarchical differential backups, you can rollback to a particular time, it has pre/post backing up hooks to do whatever dumping (db, mbr, etc) / shipping you want. You tell it what directories to backup (and filename / path exclusions) and you can set it up to deal with whatever compression you want (say via bzip2 or others). You can verify backups, unpack into some alternative target area and a few other things.
- Totz83, on 07/18/2008, -0/+1If that statement is cryptographically logical, it means that Steve Jobs will soon become an overly powerful bat like creature,
sudo apt-get jebus! - surian, on 07/18/2008, -0/+1CRON!
- leamanc, on 07/18/2008, -0/+1Any reason for specifying "-p 22"? It is not necessary, as 22 is the default port for ssh. If you were using an alternate port, then you would need to use the -p switch.
But anyway, all my backups use scripts with tar, rsync and ssh. As chr00t said, it truly is the fecal matter. Also, it plays well amongst my mixed network of OS X and Linux boxen (especially since Apple improved their bundled rsync with 10.5 to better handle HFS-specific stuff like resource forks). -
