Backup Problems
Problem Microsoft Exchange Writer backup failed
When you start a backup of a Microsoft Exchange Server 2003 Writer,
the following error is displayed:
[MAJOR]: Writer ‘Microsoft Exchange Writer’ failed to
prepare files for backup.
The reason may be the failure of the previous backup and, due to a
Microsoft Exchange Server 2003 issue, the Exchange Writer could not
perform a proper cleanup.
Action Restart the Information Store.
Problem Microsoft Exchange Server 2003 aborts the backup if the shadow
copy creation takes over 20 seconds.
If an Exchange Server 2003 Writer is being backed up, the session can
fail with VSSBAR reporting:
Snapshot could not be created.
In the application event log on the application system, the following
event is recorded:
Event Type:Error
Event Source:ESE
Event Category:(16)
Event ID:2004
Information Store (4916) Shadow copy 3 time-out (20000 ms).
Action The following can help to solve the problem:
• Limit the number of users that are accessing the management
system.
• Reduce the number of volumes in a snapshot set. Create a backup
specification dedicated to each storage group instead of one
specification for the whole server. See “Microsoft Exchange Server
Writer Backup Specifics” on page 45.
