We use rdiff-backup for onsite backups, it creates a mirror and keeps differential for Restoring to specific backup date images (although that is a file by file).
We run our nightly backups off the mirror And update the mirror every 20 minutes - except while the backup runs The mirror can be on the same system, SAN or another network Rdiff-backup I believe will work between a linux box and windows George -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Wols Lists Sent: Thursday, June 21, 2012 11:29 AM To: [email protected] Subject: Re: [U2] UV Unix File Recovery On 21/06/12 15:59, Bill Brutzman wrote: > Wol: > > Thanks.

Then run a script over the backup to create a dated backup, use ln so it's the same file in both the live and dated backup - saves disk space. Then your daily backup consists of rsync'ing the master backup directory - you need to tell rsync to delete and recreate rather than modify any changed files. Then rerun your ln script to create a new dated backup. Hey Presto - unchanged files don't take up space with multiple copies, you have a complete backup history going back however long you like, and if you have to you can free space by deleting old backups. The other thing on your backup system - consider using snapshots and btrfs, but that imho is a lot messier.
