Checkpoint backups

[datacompboy]

Is that possible/good idea to have checkpoints backups?
I mean after several changes in GUI (new user / setting / new reseller / site added/removed etc) initiate config checkpoint backup tar'ed and uploaded to external FTP ?

So in case of hardware/handware failure admin will able to restore settings easily
It can be done not "asap" but "if in last 30 mins was changes, do checkpoint and save it" -- so at least user passwords remains same -- that will increase feel of customers in case of emergency
