Note: The container number i.e. '5381' in the above error can be different.
Backup Exec Deduplication Engine i.e. spoold.exe uses the information stored in the files under /Storage/data/journal during start up for performance purpose. After changing the size of the deduplication storage volume, or if it goes unexpectedly offline, the information in these files may be corrupted or outdated leading to this issue.
Rename or remove the below files from the deduplication storage location and then restart the Backup Exec Deduplication Engine service.
/Storage/data/journal/datastore.hdr and
/Storage/data/journal/datastore.hdr_tlog
Note : Backup Exec Deduplication Engine may take longer to start when the above files are removed.
