I'll try to use some of your suggestions. Ruda On 11 December 2014 at 21:04, Anthony Sorace wrote: >> Does anybody rely on a backup scheme using, say, >> vbackup+venti on linux?

I started off using vbackup, but switched to something vac-base= d pretty quickly. I realized there was a ton of data on there that I didn't= feel the need to keep backed up (the OS itself, but more significantly nea= rly a TB of transcoded video (we kept the source backed up)).

Most of the complaining ab= out fossil's stability comes from outdated info. The fossil+venti combo isn= 't the fastest option (Erik's kenfs kicks ass there), but the tradeoffs wor= k well for my needs. > >> I am looking for a sustainable means of backup, >> mainly on linux, and am avaluating different options >> (rdiff-backup, rsnapshot, dump/restore, rdup...) > > I would use this system again if I had unix servers I cared about.
