Here's a link to the formula:

And the answer of course, is "it depends" on your source data and change rate.
If you are talking 250 VM's or less, I never know so I start with 100G, broken
up into 10 GB volumes.
Then monitor it.

Thanks for the information, Wanda.
It must be that they are migrating to tape. We migrate to tape rather often.
Do you know how large the control information is? I need to estimate how large
to make the disk pool.
Thanks again.

Each backup session backs up some control information, and that information is
restored for use during the next backup. (You can see the restores happening
if you watch the server during the backup, or if you look in the accounting
info.)
I'm just guessing, but I suspect that the "data unavailable on server" is
because it can't restore that control info.
Perhaps some volumes in your disk pool are offline, or the control information
has migrated off to tape?
If the latter, you need to put these keywords in the dsm.opt on your datamover:
VMMC your-mgmt-class-for-data-goes-here
VMCTLMC your-mgmt-class-for-control-info-goes-here
The control info mgmt. class should point to a small disk pool that can't
migrate to tape.

I'm trying to back up some VM's using DP for VM 7.1.1.0 and am getting an error
on some of the VM's and the backup is failing. I've asked Uncle Google and
can't find much. I would contact IBM support but I get very little help from
them as well.
02/25/2015 09:35:07 ANS9351E Data was not available on server and was skipped.
02/25/2015 09:35:07 ANS4174E Full VM backup of VMware Virtual Machine
'Hamilton' failed with RC=14 mode=Incremental Forever - Incremental, target
node name='VCENTER_COTX', data mover node name='VCENTER_COTX_DM'
02/25/2015 09:35:08
02/25/2015 09:35:08 ANS1228E Sending of object 'Hamilton' failed.
02/25/2015 09:35:08 ANS1314E File data currently unavailable on server
Any help would be greatly appreciated.
Thanks,
Eric
