scratch pool

[estech25]

unlike Arcserve there doesn't seem to be a default SCRATCH pool created once NBU is installed. Do I have to manually create such a pool? Does the netbackup pool which is created automatically act like scratch?

there seems to be a contridiction in your question. You ask if a scratch pool is created and then ask if the one that is created with the name scratch is a scratch pool. The answer is in the name of the pool.

No, Actually I dont have a pool named scratch. I have a pool named Netbackup. I am wondering if this is supposed to be the scratch pool and if not, where is it supposed to be

This is not the scratch pool. This is the default pool NBU uses for backups. To create a scratch pool (Depending on version) for 5.0 and above, just create a new pool and there will be an option to make it your scratch pool. For 5.0 and below you will need to edit your vm.conf and add the following --> SCRATCH_POOL=name of pool

May I ask one more very silly question:
Do I really need a scratch pool? I am doing fine without it.

No you do not have to have a scratch pool. It very much depends on how you run your system. I for example need to have a reserve of tapes which any of the other pools can call on to top up their allocation of tapes. In this way I can keep the total number of tapes down because any short fall in tapes for one of the pools is made up from the single reserve. If I had no scratch pool I would need to ensure that each pool had enought tapes free to guarentee non of them would run short.

So for example I could have 100 tapes in the scratch pool. This would be more than enough to ensure none of my other 6 pools ran short. Or I could have 20 tapes allocated to each pool which would mean I had 120 tapes for reserve. Thats 20 more just to ensure no one pool ran dry.

by the way don't use your NetBackup pool for anything but the DB backups.

Amen!

If you are already doing this then I highly suggest formulating a migration plan away from the use of NetBackup as a backup pool.

Which are listed as DB backups on the activity screan.
