Many, many businesses send the secretary home each night with a tape in her handbag for "off site backup".  We have not come across one yet who reguarly restores from the tape on different hardware to make sure they could *actually* restart their server from scratch after a hardware or software failure.

The whole tape concept is very 1990s and the new way is to use live backup to a running server. Using rsync or secondcopy we can replicate your live data to a standby server and you can check the standby server to make sure that the documents/files which you expected to be backed up are actually there and ready for use.

To go further, it is actually simple to replicate this server over a network to a remote location and to replicate the WHOLE SERVER rather than just the data.  This means that your disaster recovery system is to switch to a server which is already running with a live copy of your data.  No scrabbling around for a newserver and trying to locate a suitable tape drive whilst crossing your fingers and hoping that your tape will restore.
