It uses librsync. Your backup is a mirror, containing the most recent versions of your files. (No more messing with 'full' versus 'incremental' backups as in other backup software.) Additional metadata & diffs are also stored, allowing you to revert a file to some older version. The backup repository is just normal files (with some extra metadata), so you don't need any special backup tools to get a file out. (scp works nicely.) In the case of a failed backup job, there's a single command to run to revert the repository to the last good backup, and you haven't lost anything. This has happened to me several times due to network problems, and I've never had a problem reverting the repository.
rdiff-backup is really fantastic. I can post the commands I use to backup my OSX and Xubuntu machines if you like. (It's available for Windows as well, I think, but I haven't used that.)

Sorry about your files, I'll point out one mistake you did, that I see sooften.A lot of people seem to backup to the same tape/disk/media every time theydo a backup.I always ask them, what happens if in the middle of that backup, you system dies. You are now left with a dead system and an incomplete backup, you justoverwrote you good backup killing it when the system died. You should always rotate your backup media, just so this kind of thing doesn't happen.I know it doesn't help now, but I'm sure you'll never let it happen again.One thought about your lost data, is it possible you forgot to mount your USB drive, so could you backups have gone into /media/320GB/ naubrey/ onthe original drive ??? Hopefully. -----Original Message----- From: [email protected][mailto:[email protected]] On Behalf Of NathanEngland Sent: Monday, September 07, 2009 7:34 PM To: [email protected] Subject: rsync and deleted filesI plugged my USB drive into my system, ran my backup script and went tosupper. My backup script contains rsync -avz --delete-after /home/naubrey/ /media/320GB/naubrey/Usually, it works great. Problem is my /home/naubrey/ directory on my systemwas EMPTY and it wiped out my backup!!!!I just wiped my work laptop and reinstalled, but I had not copied my user directory stuff back because I needed to make some additional changes. Imade the changes and wanted to back up the changes, forgetting my user directory was included in my all_inclusive backup script... The USB drive is ext2 and when I came back I immediately unmounted and mounted ro.This is a typical user directory with 60GB of text files, abiword files, kword files, OpenOffice files, mp3, ogg, about 100 avi dvds, and thousandsof notes... Some files were only 2 k others were over 1GB.As I have never attempted recovery of deleted files because I am (99% of thetime) very vigilante about my backups. I design backup systems for customers!!!! ha haWhat utilities or programs are there that might automate this as I really don't care to sit and tell the system to recover this inode, and yes, thisinode, and again y to this inode as there are well over 200,000 files. Thanks for any help, insights, condolences!!! nathan --------------------------------------------------- PLUG-discuss mailing list - [email protected] To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss --------------------------------------------------- PLUG-discuss mailing list - [email protected] To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
