Re: [Nolug] Backing up linux

Probably only a few gigs a day, at the most...going by past experience. I
highly doubt all of it changes regularly. There is a MySQL db that is
probably close to a gig, so probably back that up fully every day, but as
far as the files...an rsync incremental backup would probably be perfect.
