Exchange 200 backup failure

[enormousson]

I am having trouble performing successful Exchange backups, consistently getting an error like the one below, during the start of the backup.

Information Store (3060) fab7e679-e4bf-4e42-ab5d-a379b933da7a: The backup has stopped with error -521.

The backup file is created, and then some data is written, and then the error will occur.

looking up the error code I find it is a generic error code and can be related to anti-virus products, however, disabling these has made no change and the error still occurs.

Any help or advice greatly appreciated thanks!

To add some more useful information (and to clarify i mean Exchange 2000 instead of 200!)

We are running Windows 2000 Advanced server SP4,
And I am using the NTBackup utility.
Also, this has worked in the past with no problems in the same configuration as it is currently.

thanks

Does this help:

You may receive the "ESE event ID 215 the backup has been stopped because it was halted by the client" error message in Exchange 2000 Server

it might do thanks - its not really the same error, but does tell me how to defragment and repair the information store, which may be relevant, although would require downtime i can't allow right now...

Downtime now could mean a working DB. Wait around and the store may go down irretrievably.
