Does someone know a simple backup algorithm (probably using several

experienced sysadmins and comsci graduates. I don't mind mothballing a
disk and buying an additional disk once a year for example.
Perhaps there is a package that manages this sort of thing?
Have you looked into rdiff-backup? It can backup a disk
remotely over ssh, and you can configure how far back it
archives your data. Then you can recover a version of a
given file from a specific date.
Is that what you're looking for?
IIRC rdiff-backup does not support arbitrary date restores, but only
from those dates and times on which a backup happened. For arbitrary
date restores it seems like filesystem support, at bare minimum some
kind of journalling with arbitrary rollback would be required, possibly
with an rdiff-backup-like algorithm combined with a journaling filesystem.
