Backuppc has an option to do something like that out of the backup
copies (extract the equivalent of a tar, compressed and split to files
that will fit on your backup media) but it is sort of an afterthought.
 The real focus is on keeping a history of backups online stored in a
very efficient form so you can keep much more than you would expect
online and available in a given amount of disk space.   It is much
easier to use its web interface  to pick a file from last month to
restore than to have to extract it from some huge old tar files on
dvds.
