 byteback - maintenance-free client & server backup scripts for Linux

+%description
+byteback encapsulates Bytemark's "best practice" for maintenance-free backups
+with easy client and server setup.
+
+"Maintenance-free" means that we'd rather make full use of a fixed amount of
+disc space.  Management of disc space must be completely automatic, so the
+process never grinds to a halt for reasons that could be automatically
+resolved.  Failed backups can be restarted in case of network problems.
+
+We use the standard OpenSSH on the server for encrypted transport & access
+control, btrfs for simple snapshots and rsync for efficient data transfer
+across the network.
+
+Backups should require as little configuration as possible to be safe - just
+the server address should be enough.
