I need to implement a backup system for my computers, and I'm looking for
some advice: I need suggestions for both the hardware and the software to
use.
As far as hardware, I don't care if it's an internal or external device, but
my bed is only about six feet away from my computers, so I'd strongly prefer
a quiet device, if that's possible. I don't need to retain older backups; I
just want to make sure there's at least ONE copy of my data somewhere. Is a
traditional, removable-media backup system even necessary? From buy.com, it
looks like I could get a 4-gig drive for under $90, or an 8-gig drive for
just over $100 (a nice one too: a 7200RPM Seagate). Might it be
cheapest/easiest to just stick another drive in one of the machines and have
my data mirrored across the network?
This sounds like a good idea.
Use rsync to copy one machine's disk to another in a
bandwidth-efficient fashion.
What would be the best software to go with the hardware? If I'm backing up
across a network, should I find something that just does a comparison and
only sends the changes? I've heard people talk about liking AMANDA, but I
remember last semester watching a guy in the CS department trying to get
AMANDA working on a server in the Econ department, and it looked like a huge
PITA.
I use amanda, and it is probably too much work for your aplication.
And tape isn't exactly cheap either.
