Can't get encryption to work with TDP Exchange aaargh!

[mirrorsaw]

Hi all,
My Exchange backups work perfectly fine until I try and enable encryption, then any attempts to backup result in a generic API error
ANS1235E (RC-1) An unknown system error has occurred from which TSM cannot recover.
ACN5060E A Tivoli Storage Manager API error has occurred.

According to the documentation from IBM I just need to put the following lines into the dsm.opt file for the local DSM agent (BA Client, the Opt file used for the CAD service)...

ENABLECLIENTENCRYPTKEY
ENCRYPTIONTYPE AES128
include.encrypt *\...\*

And that's it, if I comment out the last line, things work (though unencrypted).

The weird thing is that at one point the encryption was working, and after a server reboot it broke - so we know that the software versions etc. are all ok. We're using TDP 7.1.1.0 and the TSM client is 7.1.3.1 (TSM API Version).

It's driving me absolutely mad, IBM so far haven't had any helpful suggestions.

Have you tried reinstalling the BA and TDP clients or updating the TDP client?

What happens if you change the include.encrypt to state a specific drive then the subdirs with it?

include.encrypt d:\...\*

Or what happens when you surround the include argument with double quotes?

include.encrypt "*\...\*"
include.encrypt "d:\...\*"

It's possible TSM is not liking the statement due to something changing in the OS.
