Rsnapshot doesn't delete anything based on storage space.
It uses hardlinks so that it only needs to backup the changed material
and can 'reuse' the old material without it taking up any more space.

If your large tarball has changed since the last time rsnapshot ran, it
will need enough space to make another copy of it.
