Thanks for your script, I think you are right, why not keep some history
to roll back time if needed. If the drive I end up buying can contain
one or two month worth of back-ups, would be a bit stupid to
artificially limit it to a day or a week.
Actually a great option for sbackup would be: "Automatically rotate
backups when the backup drive is full."
This way one would not have to worry about running out of space, and it
would ensure that the the drive is used to its best, that you always
have as many backups/history as the drive size allows.
