Problem
The export fails with the error "Compression type used in CAB not supported by this library." However, if the DVS and DVSSP files from the problematic CAB are manually extracted and placed in their original location, the export completes successfully.

Cause
The CAB files have become corrupted. EVSVR can be run in Verify mode to determine the number of corrupt CAB files.
Solution
As a quick workaround for a small number of affected files, manually extract the DVS and DVSSP files from the problematic CAB file or from the most recent backup and place them in the original storage location on the Vault Store Partition. The export should complete successfully.
For a large or unknown number of items, the complexity of the problem requires that Veritas Technical Support be engaged to assist with the solution.
