Hi Veljko, I don't know a reason why someone should avoid rsnapshot. rdiff-backup is very similar to rsnapshot but handles the backup generations differently. rsnapshot always backup whole files (and uses hardlinks if a file didn't change). rdiff-backup just save the newest backup as normal files, every older version is stored as compressed delta. If you have to backup large files like databases or huge logfiles rdiff-backup will save you a lot of diskspace doing so (which is for me the biggest advantage of rdiff-backup). On the other hand it takes much longer to restore an old rdiff-backup than an rsnapshot one. rdiff-backup is a bit more flexible when it comes to decide when to delete old backups. rsnapshot has a fixed scheme. rdiff-backup has a command you can trigger manually (or by a script when the diskspace is running low). So, for example, you can guarantee your users that there will be a backup for at least 7 days but in fact keep files as long as there is diskspace available. rdiff-backup stores metadata (such as ownership) separately. rsnapshot just keep the settings the file has. rsnapshot have a larger user basis, so you might can expect some more support if you're running into problems. obnam uses a completely different approach. Everything is stored in a repository. It has some nice features but last time I had a look I decided against using it (but I can't remember exactly why) so I can't tell much about it. bup is very interesting but at the moment not mature enough to be used, IMHO. Also there is (at the moment) no function to delete old backups, so if you're running out of diskspace you have to buy new hardware. I'm using rsnapshot for most of my backup needs. It's very easy to use and understand. Best regards Denis Witt -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
