I have recently been playing with diffrent data resilience stratigies
(thanks to a disk failure), and i decided to settle with using ZFS
It allows for raidz, a form or striped raid, which ensures that if one
particular disk dies, the information stored on remaining disks are able
to calculate the missing data.
Not all of the disks have to be online at any given time, when disks
come online they will automatically synchronize in the background to
make sure they all are up to date.
ZFS also allows for snap shotting (or elementary backup), a way of
version controling your file system without taking any further disk
standard external disks can be used, as well as over a network.
yes, ZFS works under linux, a fuse port, and the project is not dead,
the person does work on it from time to time, although he does not
update the blog or the website.
Please Sun, make ZFS public under the GPL.
Obviously more clasical backup tools such as rsync (recommended) is
worth playing with, and unison.
If after a while you get tempted to use ZFS and you need a hand, then
I'm happy to explain how i got things set up.
Do remember though, ZFS volumes are not accessable by windows, unless
they are running across a network share.
Hope this gives some ideas.

I'm curious as to what people are using out there to backup their
systems. In the unix world, tar seems to be king but I've got to tell
you, there doesn't seem to be anything slower either. I have a 20 GB
tar backup I recently took and it takes over an hour just to find and
extract a single file. There's got to be something better than that.
I'm talking about 2 or 3 different computers at home and I don't need
tape drives or elaborate off premise storage. Is there something
better or faster I can use? I've thought about zip but I thought that
had some draw-backs. Is cpio any faster?
I'm open for ideas. Thanks.
