BE2010 R2 Exchange backup fails with error -4005


one of our customers backup is failing with the following error:


V-79-57344-759 - Unable to complete the operation for the selected resource using the specified options.  The following error was returned when opening the Exchange Database file:  '-4005 Read/write access is not supported on compressed files. '
I have been searching for a sollution but have not found it yet.
This is our Setup:
WSZ-MGT-01 = Backup server (BE2010 R2) with 1 SCSI LTO 4 Drive
WSZ-SBS-01 = Windows SBS Server with Exchange 2007
The back-up runs directly to tape. 
As  virusscanner the customer uses ESET NOD32. I have checked the exclusions and made sure all the Symantec Folders have been excluded.
I have checked the volumes on which the Exchange Data resides for compression, however is is not compressed.
How can we fix this?
kind regards,

  • So i found out backing up to disk was succesfull for the customers Exchange enviroment. because the backup had not been running for quite a while now we have decided to reconfigure this back-up to a D2D2T sollution. Our back-up jobs run to disk first without compression and then get duplicated to tape. This 'solved' our issue.
