HI I wondered if anyone could give me some tips on my thoughts around the following:
I have a NBU 6.5 environment with two IBM3584 tape libraries. Most servers backup up to disk at night, then this is off to tape during the day.
I also have a NBU 7.5 environment which has 2 NBU 5220s, with a master server. This is where I need to get to from the 6.5 envirnoment.
I am in a position where I *might* run into disk space issues on these appliances due to the amount of large oracle databases that have yet to be migrated over (my understanding is that the rate of de-dup is not as high on this data). It's a catch 22 as I won't know how it will go until I actually get these backups over onto the 7.5 environment. There is of course the possibility that the amount of disk I have available will actually be more than adequate.......
So I thought I would like to be able to partition my tape library to allow use by BOTH nbumaster servers (the 6.5 and the 7.5) - can anyone tell me if this is achievable, and worthwhile? Even if one drive were available to the new environment, this might help in the long run?
Else, I may have to opt to lower the data retention on the backup policies until I can have all of the backups over onto the 7.5 appliances, and THEN move the tape libraries over for use in this environment.
Has anyone else had to think about this, or an alternate solution?
Many Thanks
