Problem: There are scenarios where you have to verify the multiple SQL Server instances backup within limited time frame whether it meet your organization backup criteria standards or not.
Solution:
You can execute below T-SQL script to check the backup status as per your organization standard by assigning backup conditions value to backup criteria variable. You can execute below script either by connecting each SQL Server Instance or execute it by registering all the SQL Server Instances in Central Management Server (CMS).
Below T-SQL Script work with all the versions of MSSQL Server and verify FULL, Differential and Transaction Log Backup. It will check the max backup date and evaluate result based on condition as backup is Passed or Not.
Backup Verification Script will return below values. Column names are self-explanatory.
• SQLInstanceName
• DatabaseName
• db_create_ddate
• DB_Recovery_Model
• dbstatus
• windowsservername
• productversion
• productlevel
• edition
• current_datetime
• last_full_backup_date
• last_diff_backup_date
• last_tran_backup_date
• days_since_last_full_backup
• days_since_last_diff_backup
• hours_since_last_tranlog_backup
• Full_Backup_Stauts
• Diff_Backup_Stauts
• Log_Backup_Stauts
• full_backup_location
• diff_backup_location
• tlog_backup_location
You have to specify the backup condition based on your organization standard by assigning values to below variables.
