I always use Clonezilla (usabillity 100% after some learning http://www.iam.unibe.ch/~spescha/wiki/til/backup_howto ) and Remastersys (not maintained anymore I believe; big pity for Ubuntu's and livecd-lovers in general http://www.remastersys.com/ ).
Remastersys is not restricted to HD-space or pc.
I do have Redo backup (rather easy, but bugs), never tried to restore something with it (yet).
Fsarchiver looks great, but I did try to restore something sometime ago and it did something wrong with the filesystem (wrong fs), so I don't know.
For the 'short information' I use Kbackup and Ark or something like it for restore.
But there are more nice programs of course.
