Backup all Filegroups

,

Introduction :

A simple script to backup all filegroups within a database.

This will help in environments where filegroups and partioning are used to let a database span volumes for archive or performance reasons.

It will only work against databases using the FULL recovery mode.

Usage :

1) Change the @destinationpath parameter at line 12 to reflect your environment.

2) Execute the script against the database you want to backup.

Output :

The script displays and executes the appropriate backup commands to generate separate backup files for each filegroup.

Note :

I've commented out line 23, where (in my environment) I have my non-clustered indexes stored in a filegroup called NCIndexes,

In non live environments I script these rather than back them up to save space.

 

Let me know what you think,
