sp_delete_backuphistory (Transact-SQL)
Applies to: SQL Server
Reduces the size of the backup and restore history tables by deleting the entries for backup sets older than the specified date. More rows are added to the backup and restore history tables after each backup or restore operation is performed; therefore, we recommend that you periodically execute sp_delete_backuphistory
.
Note
The backup and restore history tables reside in the msdb
database.
