I've been trying to get a reliable answer on using CVS to backup my digital images to a linux box on the LAN and/or an external drive or RAID array. I'm certain there are more than a few solutions, but I have yet to find them.
What I have found is Using Digital Still Photography Devices with GNU/Linux, which has lots of info about mounting USB devices and media readers onto your linux filesystem.
This is all in preparation of my move into a larger room in this house, where I'll be able to set up my linux box. Right now it lives in the basement, unused, in perpetual sleep.
