volume pool - retention
Hello,
I do backups that have one month retention, 2 year retention backups and infinite retention backups.
To do this, I have several schedules that call a different SLP.
The copy1 do it on disk then the copy 2 is done on tape.
what is the best: a pool volume for each retention or all backups in the netbackup pool?
I always used to have only one pool (the netbackup pool) but I would like to be sure not to make mistakes.
And,can I use the same pool for two different robots?
thanks
NetBackup does not mix retention levels on tapes. So 1 week retention in NetBackup pool will not be written to the same tape as a backup with 1 month retention.
UNLESS someone has changed the default in Host Properties to Allow Multiple Retentions per tape.
So, nothing wrong with having a single volume pool.Having different pools for different retentions is a personal preference.
If it will make your life easier having 1-Week pool, 1-Month pool, 6-Month pool, etc, then go ahead an do it.Just make sure you have a Scratch pool so that tapes can automatically be assigned to the relevant pools.
If you don't have a Scratch pool, tape management will be a nightmare and you will constantly need to manually check available tapes in each pool.
