Problem is, there are no UN*X backup tools that are "simple" in a
Windows sense.
tar, cpio and dump are "simple" in the UN*X sense -- they each do one
thing very well with little overhead and much flexibility.
rsync doesn't keep older versions of files, and while it's very good
for moving changes place-to-place, it requires a bit of thought to get
it exactly right.
A cousin of rsync, Unison,
(http://www.cis.upenn.edu/~bcpierce/unison/) is a bit better as a
fire-and-forget backup or synchronization tool, but (as with most UN*X
tools), requires you to invest effort up front to understand and
implement to your needs.
Subversion and git are version-control systems that many many people
use for keeping home directories up-to-date across multiple systems.
(http://www.onlamp.com/pub/a/onlamp/2005/01/06/svn_homedir.html) But,
again, you'll have to understand how they work and then implement them
to your specifics.
HTH...
