Hello Gentelmen, I have browsed through forums and newsgroups but failed to find an answer. I have read that backupset generation can be a slow process, however, I am experiencing a slow restore from backupset. The backupset generation takes aproximately 8 (3 lto tapes) hours, however, now I see that the dsmsvc.exe I/O read bytes rate is only 1.5MB/sec . This is unbelievebly slow and I cannot find the reason for this. I have read that the previous versions of TSM client (4.*) had problems with backupset performance, but not the 5.1.* release. What can influence the restore performance so drastically ? Why is reading backupset so much slower than generating one ? Regular file restore/backup to tape functions properly and reaches 15MB/s. I do not expect that with the backupset as there is some information processing going on, but no 1.5MB/s while the cpu is almost idle.
Environment : IBM LTO3600 single drive Windows 2003 server TSM Version 5, Release 1, Level 5.0 Both the client and server is located on the same machine and has the library connected via scsi. Please help !!! Desperate.
