Problem

High IO usage on the volume used for deduplication storage when Backup Exec is idle

Error Message

 

Cause

From Backup Exec version 20.x ,using the updated engine for the deduplication storage, a higher IO usage on the volume that is used for the deduplication storage is seen. Backups, duplicate and restore jobs work at normal good rate.

In this updated version there is a continious health check of the deduplication storage running. This check yields IO when Backup Exec is using the storage for jobs.

Solution

This IO usage is a feature of the product, keeping the data in the deduplication storage healthy and available, and should give no cause for concern
