Re: [Networker] will staging process slow-down backup to disk?

It would be expected - the write activity of the backups would contend
with the read activity for access to the disk, as is the case with any
I/O. It would also have the effect of cancelling any good read patterns
you have going (i.e sequential), depending on the underlying disks and
RAID setup.
Best bet is watch iostat or your servers equivelent performance monitor,
and see what sort of utilisation your disks are hitting. If they are
not near 100% busy, something else is your bottleneck.

Should backup to disk slow down when staging process is moving data from disk
to tape?
We have Windows clients and networker server 7.3.2 using disk backup. When the staging process was running the cloning speed was 10mb/s and 2 client backups started (2 streams). The backup speed reduced to about 1mb/s. When staging is not taking place the backup speed is greater than 10mb/s depending on number of streams.
Is this expected or do i need to investigate my configuration further.
Thanks
