I'm trying to cleanup and optimize our Netbackup setup since the one person that used to manage it has left the company. We have policies that do 'disk to disk to tape'.
Most policies are similar to this:
Weekly Full to Disk - Retention 2 Weeks
Daily Incremental to Disk - Retention 1 Week
Weekly To Tape - Retention 3 Months
Questions:
1. If I want to start using the Staging Policies (all of our Storage Units are basic disks), there is no place to set retention. From reading online it sounds like retention information comes from the policy? My plan was to remove the Weekly to Tape schedule since that would now be performed by the Staging Policy... should I bump the Full to Disk retention to now be 3 months and maybe increase the incrementals retention also since I want them to stay on tape longer?
2. Doing this will start filling up the Storage Units more I would assume since all the retentions are becoming longer. From what I've read, once the storage hits 98% it starts cleaning out images as long as they've been offloaded to tape already until the storage hits the 80% full mark?
3. Our disk storage on each media server is identical, a Promise RAID-5 array with one 36TB volume (drive letter). How the last person set it up was a Basic Disk storage unit for every type of policy we would use. For example, I have an Exchange, VMware, EVault, etc storage units. But they all reside on the same physical disk. The path to each would be like F:\Storage Units\TYPE. So they all show the same % full all the time. Is this proper and how would it impact the Staging Policy whenever they hit the high watermark and start to try cleaning up images?
Thanks!
