Exchange Backup - "unable to successfully enumerate folder"

[Graham_McCann]

I am setting up a new NBU 6.5 server backing up (amongst other things) a couple of MS Exchange 2003 servers. Everything works nicely apart from the odd mailbox which terminates with;

1: (1) the requested operation was partially successful

Whilst I know that this is usually unimportant and means that only a few files were not backed up because they were in use, I get the following message detail;

09/10/2008 21:32:42 - Warning bpbrm (pid=14411) from client <client name>: WRN - unable to successfully enumerate folder: Microsoft Exchange Mailboxes:\<user name>\Top of Information Store\Inbox\Contracting out~1in\

I've done a bit of digging and I found out that this relates to folders and message subjects that contain  "-", "/" & "\". It seems that NBU translates these characters to "~0", "~1" & "~2" respectively. In our case this translation has occured (as shown by the above errors) but then NBU is still unable to enumerate the translated folders (meaning that we were unable to backup these folders). What can I do to resolve this issue?

G'avo,
having the same problem as the op.

I've searched for this "Symantec Bug ID: 1142611" to no avail.

Where can I learn more about this and the apparant fix?

Kind regards,
Shane.

Its parent is ET1142629.  The fix was included in NetBackup 6.5.1 (and 6.5.1A).  From that README:

--------------------------------------------------------------------------------
Etrack Incident = ET1143244
Associated Primary Etrack = ET1142629
Titan cases:  281-218-014 290-876-995

Description:
   An Exchange mailbox backup of folders that include the characters
   \ / ~ will fail to properly backup.

Workaround:
   There is no current work-around.
--------------------------------------------------------------------------------

So, if you're running 6.5 GA, you should apply 6.5.1 (or, ideally, 6.5.4) to get this fix.

README:
Release Update NB_6.5.1A.winnt.x86.exe provides fixes to the Veritas NetBackup (tm) Enterprise Server / Server 6.5 on 32-bit Windows 2000/2003/XP Professional server and clients. It also contains fixes for NetBackup Add-on products and Database Agents.
