Or put this program on the same VPS but instead of doing the gzipping and versioning yourself, incorporate Tarsnap[1] into the script. With Tarsnap you can also create a read/write-only key so that if someone hacks your server, a real threat mentioned downthread, they won't be able to delete your backups.

And whatever you do, check that you can actually recover from these backups every once in a while.

My only con against tarsnap is that it can take a long time to do a restore, even for a smallish (30G) backup. Last time I tested at least, I was looking at over three hours. The dev is aware of the issue and may have improved upon it in the meantime.

That is the _only_ reason I have for looking at something else.
