Hello I have a BIG performance problem with the backup of a win2k fileserver. It used to be pretty long before but it was managable. But now the sysadmins put it on a compaq storageworks SAN. By doing that they of course changed the drive letter. Now it has to do a full backup of that drive. The old drive had 1,173,414 files and 120 GB of data according to q occ. We compress at the client. We have backup retention set to 2-1-NL-30. The backup had been running for 2 weeks!!! when we cancelled it to try to tweak certain options in dsm.opt. The client is at 4.2.1.21 and the server is at 4.1.3 (4.2.2.7 in a few weeks). Network is 100 mb. I know that journal backups will help but as long as I don't get a full incremental in it doesn't do me any good. Some of the settings in dsm.opt :
TCPWindowsize 63 TxnByteLimit 256000 TCPWindowsize 63 compressalways yes RESOURceutilization 10 CHAngingretries 2 The network card is set to full duplex. I wonder if an FTP test with show some Gremlins in the network...?? Will try it.. I'm certain the server is ok. It's a F80 with 4 processors and 1.5 GB of RAM, though I can't seem to get the cache hit % above 98. my bufpoolsize is 524288. DB is 22 GB 73% utilized. I'm really stumped and I would appreciate any help Thanks Guillaume Gilbert
