Veritas NetBackup™ Deduplication Guide

About MSDP queue processing

Operations that require database updates accumulate in a transaction queue. Twice a day, the NetBackup Deduplication Manager directs the Deduplication Engine to process the queue as one batch. By default, queue processing occurs every 12 hours, 20 minutes past the hour.

Primarily, the transaction queue contains clean-up and integrity checking transactions. These transactions update the reference database.

Queue processing writes status information to the deduplication engine storaged.log file.

See NetBackup MSDP log files.

Because queue processing does not block any other deduplication process, rescheduling should not be necessary. Users cannot change the maintenance process schedules. However, if you must reschedule these processes, contact your Veritas support representative.

Because queue processing occurs automatically, you should not need to invoke it manually. However, you may do so.
