sp_delete_backuphistory (Transact-SQL)

  • Članak

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.

Transact-SQL syntax conventions

Syntax

sp_delete_backuphistory [ @oldest_date = ] oldest_date
[ ; ]

The physical backup files are preserved, even if all the history is deleted.
