Hi all,
I have two master servers in my current environment. Details are as below:
Master 1: NBU 7.1.0.4 (physical)
Types of backup: Combination of UNIX, Windows OS backups (with BMR enabled for physical machines), Agent based backups for SQL, Lotus Domino and Oracle.
Average number of jobs that run on daily basis: 7500 (within a 14 hour backup window)
No. of media servers: 15 (physical)
No. of clients: Appr. 2200
Current catalog size: 1.1 TB
Master 2: NBU 7.5.0.6 (physical)
Types of backup: Combination of UNIX, Windows OS backups (with BMR enabled for physical machines), Agent based backups for SQL, Lotus Domino and Oracle.
Average number of jobs that run on daily basis: 5000 (within a 14 hour backup window)
No: of media servers: 8 (physical)
No. of clients: Appr. 800
Current catalog size: 520 GB
Both the masters are clustered using Veritas Global custering Option(active-passive mode). Catalog resides in a LUN which is replicated to the DR master LUN using SRDF.
With more requirements coming in we are planning to introduce another master with NetBackup 7.6.0.2 on a VM. Media servers will be physical as we use tapes only.
My questions are:
1) How big environment can I support with master on VM?
2) How much catalog might be a maximum recommended size on a master hosted ona VM?
3) Our observation from our current 2 masters- Even though Master 2 has less than half the number of clients as Master 1, the catalog size has already reached 520 GB and is still growing (the type of clients is similar). Is this because of the difference in version of NetBackup? Do recent versions add more to the catalog? If yes, then should I expect a bigger catalog on 7.6.0.2?
Regards,
Neetu
