I use rsnapshot to automatically backup a few servers to save
the data onto a raid 5 disk array. I have it set to take daily and weekly
snapshots of the data.
As to the root partitions, I run xfs so that I can attach a USB or
Firewire hard drive and do an xfs dump/restore, which copies the
partition I'm after -
xfsdump -l 0 - /sourcedisk | xfsrestore - /targetdisk/
The nice thing about xfsdump/xfsrestore is the partitons don't have to be
the same size. The backup partition just has to be as big or bigger than
the original. But I generally don't make backup partitions, just use it
when swapping out hard drives.
After the copy, I run xfs_check or xfs_repair to verify the new partition.
As far as worrying about the root partition, I don't. Typically, I
can have a functional Gentoo system back to where it's usable for
it's main function in about 2 hrs. Desktop and nice things by the
next day. I learned a long time ago not to worry about the operating
system and just be concerned about the important things - the data.
The os can always be re-installed.
