Peter
Thanks. This is what I am in the process of setting up - please tell me if
this is all wrong :-)
1) Policy for backing up a small server. Storage Unit is DSSU and Absolute
Path is N:\CLIENT1
2) Policy set to run Monday morning 2am
3) Stage 2 is set to run from my MASTER SERVER in a specified Volume Pool.
Thus, it should goto Tape
I was also thinking of creating several DSSU's - one for Active Directory
Servers and one for DNS Servers. At the moment they all have their own
volume pools, so the second stage would correspond to their correct pools.
The DSSU's Absolute Pathname would be N:\DNS and N:\AD_Servers
Comments appreciated?

Simon,
At one customer site, I setup dssu's to perform cumul incr within policies.
I needed to make sure as they were adding clients on a regular basis, that I
could house at lease 1.5 full backups per client within the dssu for the
include list specified. That As time flows along, the cumul incr balance
out and reduce in size as the fulls were configured to go straight to tape
since I had the time on the weekend to endure the slow client performance
and resource hogging.
As far as what you are doing, sounds great as long as you have the disk
space for it. Keep in mind that volume pools are a per dssu match, so if
you have multiple clients going to the same dssu that you ultimately want on
different volume pools, straight phase 2 isn't going to help you. You can
always do some bpduplcate fun to get around that if you have the time to
customize.
Hope this helps.
Thanks
Peter
