+Differential backup scripts using rsync and hardlinks.
+
+This is a toolset to setup and run a backup server that pulls
+differential daily, weekly and monthly backups from any number of
+hosts and stores them on the local harddrive. For this, it uses rsync
+and its mechanism to hardlink against already existing files, so only
+new and changed files are copied over the network. This saves harddisk
+space and network bandwidth, but you still have a full file system
+hierarchy tree the same way it is represented on the host that has
+been backuped. That makes it easy to restore. The only disadvantage of
+this method is, that hardlinks on the host are not preserved (but
+softlinks and anything else are).
+
+For monitoring your backups, you can provide an email address to get
+notification in case of error and there is an Icinga (Nagios) pluging
+provided.
