Keith - Just a few thoughts you may have entertained… In that it's a network file system, network throughput may be a factor, where gigabit ethernet and jumbo frames may help. Network statistics may reveal periodic packet losses and retransmissions which slow things down: the 'nfsstat' command

Allen, Thank you for the suggestions. By 'proxy agent' I mean they are authorized to do backups on behalf of the target server. We are doing possibility one, in your set of cases, with four agents. I kept the example simple for readability, but perhaps some clarity was lost. It seems we may

We've got a similar beast. The problem is the sheer number of files, which the client must keep a list of, in order to decide which files need to be backed up. This is the whole idea behind TSM's Progressive Incremental backup model. We have found that as file counts reach the many millions,

NetApp / nSeries backup question (non-NDMP backup): Has anyone else wanted to use the snapshotroot option for scheduled backups run from a NAS client? We run scheduled backups from NAS clients for shares on a vFiler. snapdiff backups are not supported on vFilers, so we would like to do the

Allen, I see your point, finally, that BIGFS_AF will copy files, but BIGFS_GL will remove them. Clearly, splitting the backup of one filesystem among multiple proxy nodes via include/exclude statements is futile. There are 4500+ directories under /ip, so virtualmountpoints aren't workable

TDP for Exchange 6.1.3 - need help finding out how to find out what I need to find out....

Well, I'm stumped. My customer has a 2-node Exchange 2003 active/passive cluster on Win2K3 R2 SP2. TDP for Exchange is 6.1.3.3, Legacy backups. Node 1 is usually the active node, and TSM works fine. The TDPEX GUI on Node 1 works as expected. The client scheduler service for Exchange is

Wanda, Have you tried tracing the activity of the process with Sysinternals' Process Monitor? It might help in pinpointing at what stage exactly the client exits. Maybe it is trying to read a registry key and crashes on that or something. I've found Process Monitor very helpful in a number of
