Re: [Veritas-bu] Mixing Policy Types in a Volume Pool

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.

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

I have an interesting situation. I am coming into a
NBU 6.5.3 environment where the current backup admin has several volume pools.
For example, he has set up the following:
- Exchange-Full -
Exchange-Diff - Sharepoint-Full - Sharepoint-Diff - Oracle-Full -
Oracle-Diff
I would like to just narrow this down to two volume
pools: - Full - Diff
The reason for the Full & the Diff volume
pools is to have the data segregated by data retention.
His reason for
not doing this is that he claims that if the volume pools are not segregated by
Policy Type, the restores will not work properly even though the backup was
successful.
Has anyone had any issues with not being able to do a
successful restore when mixing policy types within a volume
pool?
thanks.
