How data buffer size and buffer number effect the Netbackup backup and restore performance?
Lately we are having a performance issue in our Widnow server. After looked into details, we found we had smaller data buffer size and buffer number in our Windows serve compare to our HP-UX server.
Can someone please help me with my confusings?
1. Does the data buffer size and buffer number effect the backup and restore performace dymantically?
It looks the backup performance is almost 10 times faster in our HP UX server than in our Window server.
HP-UX 11.31, version: 7.1.02, data buffer size: 262144, buffer number: 64
Windows 2008, 64bit, version: 22.214.171.124, data beffer size: 65536, buffer number: 12
2. How can we determine what is the best data buffer size and buffer number in our enviornment?
3. How can we set the data buffer size and buffer number in Window/Unix server?
4. Should we make the changes on media server only or both media server and client?
