YourSqlDba is an open-source maintenance and automation tool for Microsoft SQL Server, developed by Maurice Pelchat. Written entirely in T-SQL, it is distributed as a single script that installs a dedicated database for backups, integrity checks, index and statistics maintenance, cleanup, diagnostics, reporting, and controlled delegation of selected database operations to non-sysadmin users.

Warning

Breaking change — Starting with version 7.1.0.12 — delegated database management: Existing non-sysadmin backup, restore, duplication, backup cleanup, or maintenance-mode workflows may stop working after this upgrade. Each delegated login and its authorized databases must now be configured in Maint.DelegatedDbManagement, and restore targets must follow the new naming restrictions. Review the delegated database management documentation before upgrading any instance that uses delegated operations.

YourSqlDba operates through SQL Server Agent jobs and Database Mail, both of which must be configured. After downloading and running the YourSqlDba script, execute Install.InitialSetupOfYourSqlDba once per instance. This procedure configures Database Mail, backup directories, and default behaviors. It also creates and schedules two SQL Server Agent jobs. Future upgrades do not require rerunning this procedure.

Each job has a single maintenance step. Both call the main stored procedure, Maint.YourSqlDba_DoMaint, with parameters appropriate for the job type. These parameters are documented in detail in the online documentation.

The generated report and logs now include the list of databases selected by the maintenance filters, so users can verify the exact database set targeted by each run.

YourSqlDba is a large T-SQL script that automates database maintenance tasks for SQL Server. It creates a database named YourSqlDba containing T-SQL modules, including functions, stored procedures, and views. Most operate behind the scheduled maintenance jobs, while some are also useful for occasional DBA work.

Latest release: 7.1.0.12

1. Controlled delegation of database management operations

   YourSqlDba now provides a least-privilege delegation model for application owners and senior support users who need to refresh non-production databases, test or roll back application upgrades, or clean up backups without receiving sysadmin privileges.

   A sysadmin authorizes each delegated login through Maint.DelegatedDbManagement. Restore targets are restricted by naming rules that prevent delegated users from overwriting source or unrelated databases.

2. Simplified transaction log backup file management

   The initial transaction log backup produced after a full or differential maintenance backup now keeps its own file name and is no longer reused by the regular log backup job.

   The next regular log backup creates the reusable log backup file and records it in Maint.JobLastBkpLocations.lastLogBkpFile. When @BkpLogsOnSameFile = 0, each regular log backup continues to use a new file.

3. More resilient YourSqlDba upgrades

   Upgrade information is preserved temporarily in the YourSqlDbaUpgradeSavedInfos database. This protects the existing configuration if an upgrade fails. The temporary database is removed after a successful upgrade. Exclusive access handling during upgrades has also been improved.

4. Exclusive access for delegated restores

   Before a delegated non-sysadmin restore, YourSqlDba terminates active sessions connected to the target database. Delegated users cannot normally terminate those sessions themselves, and their restore targets are already restricted.

   For sysadmins, sessions are not terminated automatically because a parameter mistake could affect an unrelated or production database. Sysadmins must handle active sessions explicitly when using Maint.DuplicateDb, Maint.DuplicateDbFromBackupHistory, or Maint.RestoreDb. They may call S#.KillDbUsers explicitly when appropriate.
