| I don't think splitting it into filegroups will make the backup faster, but you could choose to only back up certain filegroups - and you then need to be sure that you will be able to restore a consistent view of the database ...You can backup onto multiple devices concurrently - so you could backup to a pair of disks, on separate controllers, for example.Folk with large databases often use SQL Litespeed for backups which they say is much fasterKristen |

And they are correct! It is much faster and we use it all the time for large DB's.

| thanks for the reply. il look into sql litespeed. my question was how do i split the original data into different filegroups though? also if i back up each filegroup into different diskdrives does that mean i need a full backup on each diskdrives where the filegroups are located as well? thanks. |

| You can create new filegroup then move table to it, but it doesn't solve your backup issue as said above. You can backup filegroup, but makes restore more complex. How big is your db anyway? |

| I suppose you could choose to NOT backup a filegroup, if that would help (e.g. masses of NON-changing data)Kristen |
