I get 16 MB/Sec using bigasm with anywhere from 1 to 6 tape drives in seperate test. I believe this is uncompressed, correct? When I back up Oracle datafiles I get 27 MB/Sec for 1 drive, 23 MB/Sec for 2 drives, 19 MB/Sec for 3 drives, and 16 MB/Sec for 4 drives. I see no hardware bottlenecks...

If your backup server is UNIX, try the fuser command. Ex. fuser /dev/rmt/0mnb This will list the process associated with the tape drive which you can then kill. The nsrmmd process will restart and then you should be able to unmount the drive. FYI, there is another note in this forum that...

Is anyone out there doing SAN backups and getting better than 24 MB/Sec compressed performace out of LTO-1 tape drives? Kent

Desperate Sysadmin, Is it possible you have a stale NFS mount on one of the clients that is in the savegrp? Kent

Hello, Just wanted to point out a feature (bug) with mminfo. I have noticed that duplicate lines are produced when a client has had a lot of data backed up and it spans multiple volumes. The only way I've found to get around the reporting problem is by piping the output to 'sort -u' (for HPUX)...

Not sure if this answers your question, but here goes. If you have virtual clients defined in Networker that you want to only back up the relocatable file systems, then in the client setup add the command 'save -c client_name' (client_name is the vitual client) to the 'Backup command' setting...

I had the same problem with the indexes but on HPUX 11.0. I received a new 2.1 backint binary from Legato that has solved this issue, hopefully there is one for NT as well. Hope this helps. Product: NetWorker Release: rt_linuxnmo31 Build number: vsadjadi-2001-361...

Never mind, I figured out the problem. I discovered that the server parallelism was set the same as 1 drive. Kent

Hello, Does anyone have experience getting the backup to use multiple drives? Legato's doc is skimpy at best. Any help would be appreciated. Kent

If you are using backint which is the SAP application module, then you don't initialize tapes from sapdba. You need to set up the init<SID>.utl file with parameter backup_dev_type = util_file. You will also need to set up the init<SID>.utl file to use a specific pool and group. You then label...

Do you want to move the media database, client indexes and resource files to the new server? If so, then a server to server move will work. This procedure also assumes a separate bootstrap and client index backup is done to one tape. You will first need to temporarily rename the new server's...

I have a similar environment. I don't use sapclone, but I do use nsrclone and have had good success restoring the database with brrestore using clone tapes from both offline and online backups, including point-in-time recovery. Hope this helps. Kent

I've seen this message a lot too, but the cause of it in my environment was hardware cleaning being turned on. When the tape library loads a cleaning tape and at the same time Networker trys to load a tape for a backup, Networker gets confused. I'm cleaning my drives manually now and the read...

Is the Networker daemon running on the client? Are any of the file systems backing up successfully on the client? Kent

Hello, Has anyone moved a UNIX 6.x Networker Server to another server with a different hostname? Legato Technical bulletin 121 addresses the issue for versions 4.2 - 5.5.3 but I've seen nothing for 6.x. Recovering the media database and /nsr/res/* files is no problem with mmrecov, but how do...
