Lets talk about something exiting for a change, what is your personal backup policy? Here is mine: - I backup my online accounts every two weeks. Google has full export including GMail: https://support.google.com/plus/answer/1045788?hl=en . For some websites I use scripts to do website mirroring. - I make full phone backup every two weeks - I have incremental daily backups inside computer. So I have daily snapshots o…

Nothing. I don't have any digital assets I care about.

I wish that they included options for Linux too. What Linux backup tools do people use? Currently I'm making do with a bash script that's just a wrapper around rsync, but it'd be nice to have something a little more powerful, especially with the option to back up things to glacier, etc.

Yeah, would have loved to have something for all platforms... Haven't used Linux in a long time so I'll admit I'm unfamiliar with it all. Did try to do some research but couldn't find a solution that would cover all distros.

Next year, with more time, I'll try and add something there!

I use tarsnap for all my backups, but that's a service as well as a tool. This is my daily crontab: http://pastie.org/8982530

Same here. Just did a full backup of my VPS:

               Total size Compressed size
  All archives 3.7 GB     1.5 GB
Deduplication ftw.

Has anyone created a backup app that interfaces with glacier?

Arq works quite nicely with Glacier: http://www.haystacksoftware.com/blog/2012/11/arq-cloud-backu...

Just on Mac OS X, alas.

For your purposes, it would be fine to post something that works on Ubuntu as long as you can verify that it's not Ubuntu-only (if it's open source and works on at least two distros, chances are it works on any distro)[0].

[0] Heck, even most things that are made for Ubuntu work on other distros with minimal modification - it's just a matter of convenience.

I find that surprising. Even if you don't have anything unrecoverable, like personal photos and such, just having to reinstall and reconfigure everything from scratch is more than enough reason for me to backup stuff up. Especially since I know I won't remember half of it.

Do you do anything to check against corruption (e.g. bit flipping)? I've been experimenting with md5deep recently to accomplish this, but it's a little time-consuming. I'd be very interested in hearing about more efficient ways of dealing with this problem.

No, except daily snapshots. If I would find main version corrupted I can always recover old version a few month back. I

I found bit flipping problematic only when transferring larger amount of data over network.

Just use ZFS. It works.

But, as with the old adage "RAID is not backup", don't forget that ZFS is not a backup either.

ZFS has bugs like any other codebase, and metadata corruption will make your whole pool unrecoverable. RAID-Z and block checksums won't save you from that.

I speak from personal experience with ZFS. Backups are important, no matter what filesystem you use.

I actually did a wipe and clean install of my computer a few months ago. I couldn't think of a single thing to keep so I didn't and the only thing I've reinstalled since then is Chrome.

Please also remember that a backup is only as good as the restore process. If you've never had cause to test that your restore process works as intended then you're still vulnerable.

PS: I admit that while I keep backups, I've not once checked that I can actually restore (but I know I should). I suspect many people are the same.
