Description:
Issue
A few customers have reported that the TDR Mac Host Sensor can cause high CPU utilization and memory usage when a Time Machine backup is in progress. This can happen if the Host Sensor tries to scan files while Time Machine is creating them.
Workaround/Solution
In TDR, add an exclusion for the Time Machine backup volume and snapshot folder. The backup volume could be an external USB drive or a network drive and is typically mounted as /Volumes/<BackupDriveName>. We recommend you add a TDR exclusion for the backup volume.TimeMachine also saves local snapshots when the backup drive is not available. The snapshot folder is usually /Volumes/com.apple.TimeMachine.localsnapshots/Backups/backupdb. We recommend that you add an exclusion for the Backups.backupdb folder and all subfolders. For information about how to add TDR exclusions, see Configure TDR Exclusions in Fireware Help.To find a mount point in macOS, open a Terminal window and run the mount command. Provide a screen shot of the results to Support if you require assistance.
