Incremental backups, rollback to checkpoint

[jpletka]

I'm looking for a backup solution to archive website data from Linux and Windows 200(0/3) servers. What I'm needing is source control type functionality where I can look at change history and restore a directory or file from a particular day. (All archive will be to hard drive -- no tape).

Is Amanda an appropriate tool for this? To save on space, I'd also like it to automatically discard history over 1 week. Is this possible?

If it does not have change history, would a nightly backup override all prior backups?

Amanda will be a good tool that will meet your needs. It can backup to disks. You can have retention policy of 7 days (so that all backups before 7 days are discarded).

Amanda does maintain catalog of each backup run. It does have information on which
files where backed up in each run. It does not maintain change history similar to
source code control system. You can look up the list of files backed up in each
run and restore the specific files from the backup.

I don't understand what you mean by "nightly backup override all prior backups". All prior
backups are available for recovery if needed. If you configure the retention policy to 7 days, all backups older than 7 days are overwritten.
