+store duplicate regions of it only once, then compress and optionally
+encrypt the result.  Feed another @file{.tar} file, and it will also
+re-use any data found in any previous backups.  This way only new
+changes are stored, and as long as the files are not very different,
+the amount of storage required is very low.  Any of the backup files
+stored previously can be read back in full at any time.  The program
+is format-agnostic, so you can feed virtually any files to it.")
