Just as a quick survey,.....based on number of clients, regardless of
drive type, speed, etc,
=20
What would any of you consider a MINIMUM number of tape drives for an
environment with ~100 network based clients and 2 TB of data?? 200
clients and 4 TB? 400 clients and 8 TB?
=20
I'm not looking for minimum number of drive to backup x terabytes of
data, in y hours, as that is more just math, and how fast a drive will
stream data, assuming your clients can push it fast enough.
=20
I'm looking more for what you would feel comfortable with, knowing that
a job(s) can hang due to Windows Open File Backup tanking, or a tape
getting stuck in a drive, or a large job failing at the last minute and
having to be restarted, or a SCSI error downing a drive, etc, etc.
