storeBackup is a disk-to-disk backup tool for Linux. It should also run
on other Unix-like machines. You can directly browse through the
backed-up files (locally, via NFS, via SAMBA, or whatever). This gives
the users the ability to restore files easily and fast. The user only
has to copy (and possibly uncompress) the file. There is also a tool
for easily restoring (sub) trees for the administrator. Every single
backup from a specific time can be deleted without affecting the other
existing backups.
