[HowTo] How can I keep my backups for x days?

[ephigenie]

I think so - from a first view it seems ok for me.

There might be still some issues regarding quota calculation (are ALL the Backups excluded)
I mean if a reseller might set "keep backups" to lets say 60 days and one of the pages of his customers is some kind of bigger online shop with maybe 2 gb - then this'll add up to 120 gb.
And maybe only 2 gb is counted ... so there should be a switch for admins to allow their resellers to have quota with and without backups .
