SQL Server, Backup Device Object

The Backup Device object provides counters to monitor Microsoft SQL Server backup devices used for backup and restore operations. Monitor backup devices when you want to determine the throughput or the progress and performance of your backup and restore operations on a per device basis. To monitor the throughput of the entire database backup or restore operation, use the Backup/Restore Throughput/sec counter of the SQL Server Databases object. For more information, see SQL Server, Databases Object.

This table describes the SQL Server Backup Device counter.

SQL Server Backup Device counters


Device Throughput Bytes/sec
