I am down to 4 volume pools.

 

1 for catalog

1 Databases ( just so the multiplex is less so restores are faster)

1 for LOOOOONG retention

1 for everything else

 

I do not mix retentions on the same tapes, and tapes are removed from the library everyday and sent offsite.

 

I mix my windows, unix, and exchange all on the same tapes.  This allows me to use a tape Fully, and reduce the number of tapes needed.

If we did accounting where each department needed to pay for tapes then many tapes might work.  But with tapes holding so much data now, I would never be able to Fill and tape and would be using many more then I am now.

 

 

We are trying to reduce the amount of volume pools for our Oracle / SAP / Exchange systems as they seem to have one PER system!! And it has cost alot of time and trouble in managing tapes.

 

Where possible, we try to "reduce" the volume pools down, and try to keep the retentions the same.

 

I have not been a fan of "mixing retentions per media" using the Global Option on the Master - Not sure what others views are on this ! But it was disabled by Default....

All,

 

If you think back to the original idea behind volume pools it might help understand where they come into play. The idea was to segregate tapes into separate pools based on business units so that the cost of tapes could be tied to a specific unit. For example if the Accounting department needed 100 tapes they would either buy them or pay the infrastructure team to buy them and these would be their tapes. If the HR department need data backed up they would buy their tapes and neither the twain would meet. I don’t know if this little history lesson was of any use, but I’ve got nothing better to do at the moment any way. J

> Has anyone had any issues with not being able to do a successful restore when mixing policy types within a volume pool?

No. And if your full and diff backups have different retention periods, they will end up on different tapes anyhow, even if they are going to the same pool (assuming you don't have "Allow multiple retentions per media" enabled).

We have just 3 pools. "onsite", "offsite" and "archivelogs". The "offsite" pool gets ejected every morning and given to a man with a truck. We direct Oracle archivelog backups to their own pool because we DON'T want them on the same tapes as the database backups. Everything else gets mixed in together.

Cheers,
Dean
