Yes, this would work with tar, too. However, date-based incremental
backups don't work well 
* for large files with small changes
* when you can't trust the time stamp (what happens when files or
  directories are moved? file hierachies untarred?)

Some sort of "rsync/unison into an encrypted tar archive" would be
nice. Any ideas how to achieve this in userland?
