I currently have a backup system that stores everything I want to backup in a single file. The file is approximately 15 GB. The backup is made nightly.

I'm looking for a system for a Linux server that will keep daily backups for 7 days, weekly backups for a month, and monthly backups indefinitely.

I'm trying to find a system like this, but don't really know where to start.

Is there an existing system that does this? Or am I better off writing my own?

    I have to say that you can't have looked very hard if you're not even sure such a system exists.

Amanda and BackupPC are both widely-used and well-respected F/OSS backup utilities. Either one of them could be configured to maintain the backup aging/rotation that you specified.

If you wanted something more simple, you could look into rdiff-backup or rsnapshot.

  • I have used BackupPC for a few small shops and had good luck with it.

Bacula can be configured to do this. You can probably find something here too.
