Backing Up and Restoring Filegroups

Hi,
Please can someone advise if the following is possible?
I have a production and a dr site with the same database on.
If I have a table which is partitioned by month and only the current month is updated daily.
I want to backup only this Filegroup and restore it against DR daily. Is this possible?
Thanks for taking the time to read my post.
cheers.
Jamie.

Hi Frank,
Thanks for the reply.
I have taken a look at BOL and am a little bit confused what exactly I need to backup to make this work.
If I use Filegroup backups can I backup just the one I am interested in. Or do I need to backup and restore the Primary filegroup as too.
I don't believe it is practical for us to do a full backup monthly is the db is 0.5TB and the kit it is on is under powered.
Thanks
Jamie.

Arghhhhhhhhhhhhhhhh. I'm going to explode. Or am I just thick? Please don't answer that.
I am able to restore an additional FILEGROUP but then the others are left in a state of RECOVERY_PENDING. The scenario is:
1, create db with two additional filegroups and partitioned table.
2. Insert some data
3. Do a full backup
4. add new filegroup and change partition stuff to create new partitiion on end
5. backup primary and new filegroup
6. DROP the database
7. Restore the full backup. At this point all filgroups are online total of three including primary
8. I now want to restore the additional 3rd Filegroup backup. If I use the followingRESTORE DATABASE Test
FILEGROUP
= 'PRIMARY',FILEGROUP
= 'fg03'FROM DISK = N'D:FG03.bak' WITH RECOVERY, REPLACE, PARTIAL
GO
The 3rd Filegroup comes online but the other two are now RECOVERY_PENDING
Please help.
Thanks
Jamie

yeah. At last
The following was what was missing.RESTORE
DATABASE Test FILEGROUP='FG01' WITH RECOVERY, REPLACERESTORE
DATABASE Test FILEGROUP='FG02' WITH RECOVERY, REPLACE
The whole script is a s follows.use master
go
IF
EXISTS(SELECT * FROM sys.databases where name = 'Test')BEGIN
alter database [Test] set single_user with rollback immediate
