Hello,
I protect linux servers with TSM on Windows. But on one server, the performance are very poor. For example, I have 2 servers, serverA and serverB and during the night I can see:
ServerA:
Objects Backed Up : 4,500,000
Objects Updated: 5000
Bytes Moved: 10Gb
Elapsed Time: 7:30
% Compressed: 42%
ServerB:
Objects Backed Up : 15,000,000
Objects Updated: 25000
Bytes Moved: 6Gb
Elapsed Time: 3:00
% Compressed: 47%
It means that the second servers backed up more than 3 times more files in 2 times less long. And I cannot explain this difference. The sysadmin tell me that RSYNC is more efficient on ServerA than with TSM.
Could you tell me what I can check, try or measure to diagnose and solve this problem?
Thanks by advance for your assitance
PS : I forgot an important info, the backup consists only in flat files backup.
