Helmut,
Your plan of backup to disk then to tape is excellent.
If you need to perform a recovery, retrieving the files from disk is
quick and requires no manual intervention (finding and loading tapes).
Reading from disk will also be faster. If for some reason, the files on
the san are unavailable, you can load the tapes.
