在 SQL Server 2014 中备份维护计划或作业

Question

I have some maintenance plans in SQL Server 2014 that they do some tasks on my databases. I want to back up my plans to use them on different servers.

How can I back up or deploy them?

Answer 1

Jobs and maintenance plans are stored in the MSDB system database. You can backup and restore jobs and plans by backing up and restoring this database.

To deploy jobs, you generate the appropriate script and run it on the target server. You can generate an existing job's script by right clicking on it and selecting Script Job as > Create from the context menu.

Maintenance plans can't be scripted that easily. Essentially they are SSIS packages stored in MSDB. You can create your own SSIS packages with the maintenance tasks you want and deploy them to a server.

Most DBAs though prefer jobs because they have the same capabilities as a maintenance plan and are far easier to script and deploy.

Ola Hallengren's scripts are frequently used to perform maintenance tasks like backing up multiple databases or rebuilding/reorganizing indexes automatically, using a single command. For example,

EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES',
         @Directory = 'C:\Backup',
         @BackupType = 'FULL',
         @Compress = 'Y',
         @Verify = 'Y'

Will take a full backup of all user databases with compression while

EXECUTE dbo.IndexOptimize @Databases = 'USER_DATABASES',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationLevel1 = 5,
@FragmentationLevel2 = 30

Will check all indexes and decide to rebuild or reorganize indexes based on the fragmentation level

Answer 2

All these maintenance plans are created by developers or administrators by using below steps

Under Management -> Maintenance Plan wizard or Maintenance Plan

After selecting Maintenance plans by running wizard you can select what are all maintenance plans you can select as below:

By selecting respective plans if you generate it will generate SQL Jobs, You can script these SQL Jobs to take the backup also you can enable and disable these jobs based on requirement.
