Coffe hasn't started working yet - What kind of throughput is that, from
the job log?
Is this a local backup or network?
if network is only one remote machine slow, or all of them?
Is/Are the tape device/library on their own SCSI Controller?
Is anything else scheduled to run on the backup server during backups?
AV Scan? ScanDisk?
Are your using a OGL screen saver on a non-OGL video card?

It's local backup with their own SCSI controller.

No virus scanning or other job is running when the backup job is running and
the server is not using any screen saver.

Make sure you're not using the options "write checksums to media" and "verify
after backup". Those will kill your job times. If however they are important
to have these done then you may be stuck.

I have unchecked this option.

What's the throughput now?

You're backing up 700GB in 12 hrs??? That's fast already.

The throughput now is 350MB/Min

Sorry the capacity is being backup now only around 500GB

Is this anywhere near the tape specs? The backup throughput depends on the
data set. I've used an LTO tape drive to backup thousands of small text
files, total size is 30GB. The throughput was slightly faster than a DAT
(DDS3) tape drive (sad, isn't it?).

350MB/min is approximately the speed of a DLT1 tape drive (compressed
transfer rate). If you're using a DLT drive, that sounds about right.
