> For backup, you can rsync to a directory named for the date under a main backup directory (e.g. /media/backup_disk/MyBackups/20110716T190000/).

>    1) Using different directories on a single partition makes it easier to manage all the data (plus you don't hit the limits on the number of partitions permitted on a device).
>    2) It avoids the problem of figuring out which partition to mount for a backup without mounting them all and searching through the contents.
>    3) It makes rotation simpler (just delete anything more than X days old after a backup if the disk is getting more than Y% full).
