Snapper creats a snapshot every hour and deletes snapshots once a day. After that cleanup the number of snapshots will match the numbers from the config file. But after some hours the number of snapshots will have increased again. > I've used rsnapshot before and configured cron to run two hourly's a day.

I don't like the rsnapshot algorithm since it assumes your system is running all the time. With snapper you can have your system run infrequently and still have a snapshot about once a month in the long run. > Also it would be nice if the description could be updated to "timeline - > daily" to indicate it is kept because of some rule. That could mean that the description of a snapshots changes over time. E.g. a snapshot that is keep today due to the hourly limit could be keep tomorror due to the daily limit.
