Backing up data on Linux and Unix is a beautiful thing. It's beautiful because
everything that you ever need is at the command line and can be easily scripted
and put in cron jobs.
On my systems I basically use two things; tar and rsync. Sometimes I'll also do
whole disc clones using Clonezilla. Clonezilla is a live CD distro that is
self explanitory when you run it. Just make sure your destination disc is as
big or bigger than the source disc. Clonezilla takes care of everything else
for you, it even backs up NTFS partitions. I don't see the need to explain it
further. There is plenty of documentation about it out there if you never used
a disc cloning program before.
Anyway, below I put some files about using tar and rsync. I'll add more
content in the future if need be.
