CAUSE
On-access/Real-time scanning functionality of various anti-virus applications can be quite debilitating to system and backup performance while Unitrends is performing a backup. In certain cases, backup operations may timeout causing various errors reported by the client and the appliance if on-access/real-time scanning is too disruptive to the backup process. Please use the following steps for the AV vendor being used to prevent files Unitrends processes are attempting to read/write from being scanned during backup operations.
