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 is the SQL Server Backup Device counter.
| SQL Server Backup Device counters | Description |

| Device Throughput Bytes/sec | Throughput of read and write operations (in bytes per second) for a backup device used when backing up or restoring databases. This counter exists only while the backup or restore operation is executing. |
