Restore from tapes to ASM for one of our Oracle RAC 10.2.0.4 database on 3 node cluster (GRID - 188.8.131.52) is giving sleepless nights.
Netbackup - NO hardware multiplexing.
Database size - 300 GB
Backup Time - 1 hour
Backup Transfer speed - 112 to 131 MB/s
Restore Time - 2 days
Restore Transfer speed - 300 to 600 KB/s
Restore to ASM disk
I did small test
Restore datafile 5 (7Gb appr) to Normal FS. It ran fast and got completed with 112 KB/s speed.
Restore datafile 5 (7 GB approx) to ASM disk. Its very slow at 600 KB/s speed. Restore completed after 14 hours
LUNs size and speed are same for ASM disk and Normal FS
Experts, Does anybody had this issue earlier?
