I think that is what I still don't have here in my area. A good NAS. hmmm I forgot about that. Time to request and/or check inventory from logbase :-) Snapshop from for a filesystem. Thanks for this. I was looking for such a solution in my other questions. Set up 1 & 2 and use your usual rsync/amanda/backup scripts.

To the original OP, sorry if somehow I am hijacking your tread. But it goes to show that even if you can verify the backup in your tape, it does not mean its going to be there when you need them someday. So, beside tape, get another backup system. Cheers,
