One of my customer is facing major performance issue on MS-Exchnage 2010 database backup.
BA : V6.2.2
TDP-exch : v6.1.3
sta : v5.5.4
TSM Server : 5.5.4
Database size : 500 GB
Transactional logs : say 100-150 GB (each has 1 MB in size)
When we execute the backup via tdp (Copy backup) 500 GB data gets transferred on tape in approx 4 hrs but takes more time at the time of transactional logs backup (i.e incremental bkp).
For about 150 GB of transactional log backup it was taking approx 25 hrs.
Customer has three exchange nodes with multiple databases running on same(Active-Passive combination), I had tested the backup from multiple database passive DB copy, but results are same.
Does anyone faced this kind of challenges? Pl share some inputs..
