So you setup the SQL server database backups and checkdb maintenance plans when a server went live. Therefore your disaster recover plan is done…. right?
The only way to know if a database backup can be restored is to restore it and run checkdb on the restored database. However, depending on how you have transferred the database backup file to/from its storage location, there is no guarantee that the data is still valid nor that the backup file is safe to restore (see SQLSkill’s article below).
Automating the entire database backup, checkdb, restore and validation process is essential to eliminating errors during critical disaster recovery moments. The DBA’s disaster recovery plan should start with a solid backup and recovery strategy. There should be 100% confidence in that process by the entire DBA team. Oh and you actually need to test that process on a regular basis … right?
It will save your company from appearing in the newspaper headlines and it will save your job too.
