I want this to be fully automated and I only need to backup a few directories with key configuration files and data files... nothing fancy but it would be very nice if it wasn't one big bash script. -- 09:F9:11:02:9D:74:E3:5B:D8:41:56:C5:63:56:88:C0

I've played with a lot of backup tools and found two satisfactory workflows for Linux: (1) XFS and xfsdump. (2) rsync with --link-dest (i.e. hardlinking) Day 0: rsync -avx --progress /source /dest/backup.day0 Day N: rsync -avx --progress /source /dest/backup.dayN --link-dest /dest/backup.day(N-1) This will do incremental backups on any system that supports hardlinks; you will have one folder per backup point, and only modified files are rewritten. I love this setup because every backup point is immediately accessible using standard tools. The tool rdiff-backup can achieve the same effect but with delta-compression between differences, but you only get the top-level flat-directory view of the latest snapshot, you have to use various rdiff-backup commands to extract older snapshots from the archive. -- Ubuntu MOTU Developer and Forums Council

joako Premium join:2000-09-07 Gainesville, FL	reply to joako I want nothing to do with hard links, rsync or even NFS. Script to create an archive, prefer .tgz, and then copy that archive via FTP, SCP, SSH (perfer encrypted but then again half these backups will be on the local lan or via a VPN) The biggest thing that needs to be backed up is a quickbooks file. -- 09:F9:11:02:9D:74:E3:5B:D8:41:56:C5:63:56:88:C0
