[!INCLUDE SQL Server]
The Backup Device object provides counters to monitor Microsoft [!INCLUDEssNoVersion] 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 [!INCLUDEssNoVersion] Databases object. For more information, see SQL Server, Databases Object.
Note
The SQL Server Backup Device counter are not currently visible from sys.dm_os_performance_counters. On Windows, the counters can be viewed from System Monitor.
This table describes the [!INCLUDEssNoVersion] Backup Device counter.
