RE: incremental onbars

Db is around 2 TB. We are using ISM and onbar. Other parts of the business have been using Veritas SnapFlash ( I think I got the name correct) to take disk snapshots. That is definitely an interesting option. I plan to run an incremental onbar to see how long it takes. Thanks -----Original Message----- From: Sebastian, Norma J.

I can't imagine why it would. Perhaps as already posted, you are hitting a bug. You also did not mention what backup software is paired with onbar, perhaps there is something set inefficiently in the backup software and/or the relationship of onbar with the backup software. Work with your backup software vendor, and network people, maybe you are getting the best throughput you can given your total environment. And if that's the case and not good enough, as already posted, you could look into external backups (wherein you issue a block on informix, do some type of OS/disk copy(i.e. EMC BCV split), then unblock informix). External backups take only seconds depending on your OS/SAN abilities.
