`rsnapshot' and `dirvish' provide this, I think[1]. Otherwise these

I wouldn't call them useless. It is better than nothing even if you have to do a base system install to get the replacement system to a point where you can restore. And sometimes you may want to restore on a different layout or just grab a copy of a file or directory that was accidentally deleted. Backuppc provides a handy web interface for those operations and will let you download a file or tar/zip archive of multiple files through the browser.

: One of the easiest would be to download the bootable iso for : clonezilla live (http://clonezilla.sourceforge.net/clonezilla-live) : which will save compressed disk/partition images to local/nfs/smb/ssh : locations and knows enough about linux and ntfs filesystems to only save : the used portions. On restore, it will re-create the partions, copy back : the contents and make the disk bootable for you.

This sounds nice. I'm not sure if either of the applications I
menioned remember the partition structure. One may have to do the
partitioning separately. It's good to save a copy of `fdisk -l' and
`vgdisplay -v' with each backup, I suppose.

Does clonezilla remember Logical Volume or Software Raid
info and re-create it too?

It does handle LVM, but doesn't currently do raid. It is probably still usable if you manually create the raid devices first and restore by partitions instead of the whole disk. You can drop to a (debian live) shell for certain steps if you know what you are doing.
