So should I do a daily backup to the local drive and then backup up  
*that* data file to the tape?  Or how would it work?  We use  
BackupExec 10 right now but aren't completely adversed to changing to  
something else, especially as our licenses are up for renewal anyway.

Right now I'm thinking of an NLE drive in a Firewire enclosure - do  
you think a Serial-ATA or e-SATA setup would be more reliable?  We're  
not looking to spend too much on this so SCSI and SAS are out of the  
question.

What I'm aiming for is a weekly backup and then daily incremental  
backups.  I'd like the tape backup to basically be a mirror of the on- 
disc backup if possible (if it happens at the weekend its pretty much  
guaranteed to be).

Thanks.
