How to Restore an Archived Filegroup on Another Server

Hello,

I have several archived filegroups that have data in them partitioned
based on the date. These filegroups have been removed from database
after archival. For example two months ago. Meantime my production
database is populating everyday.

Now I would like to restore one of my old archived filegroups. In order
to do that I would like to backup and restore the current Primary
filegroup to another server, and also restore the archived filegroup
into that server. The backup commands to backup the archived filegroup
and also backing up the primary are:

BACKUP DATABASE [DB1]
FILEGROUP = 'PRIMARY'
TO DISK = 'C:\DB1\PRIMARY.BAK'
WITH  INIT ,  NOUNLOAD ,  NAME = N'PRIMARY Filegroup backup',
NOSKIP ,  STATS = 10,  DESCRIPTION = N'PRIMARY Filegroup backup of
DB1',
NOFORMAT

BACKUP DATABASE [DB1]
FILEGROUP = 'DataGroup383'
TO DISK =  'C:\DB1\DataGroup383
.BAK'
WITH  INIT ,  NOUNLOAD ,  NAME = N'Filegroup backup',
NOSKIP ,  STATS = 10,  DESCRIPTION = N'Filegroup backup of DB1',
NOFORMAT


Later I move the backup files to another server and use these commands
to do the restore on new server:

RESTORE DATABASE [DB1]
FILEGROUP = 'PRIMARY'
FROM DISK =  'C:\Archival\Backups
\PRIMARY.BAK'
WITH FILE = 1, NORECOVERY,
MOVE 'PRIMARY01' to  'C:\MSSQL\Data\DB1\P
RIMARY01.mdf'

RESTORE DATABASE [DB1]
FILEGROUP = 'DataGroup383'
FROM DISK =  'C:\Archival\Backups
\DataGroup383.BAK'
WITH FILE = 1, NORECOVERY,
MOVE 'DataFile383' to  'C:\MSSQL\Data\DB1\D
ataFile383.ndf'


At this point the database can not be used yet and it is on restore
mode then I use this command to recover it

RESTORE DATABASE  [DB1]  WITH RECOVERY

But I get an Error:

"Server: Msg 4318, Level 16, State 1, Line 1
File 'DataFile383' has been rolled forward to LSN 5848000000402600001.
This log terminates at LSN  5848000000387700001,
 which is too early to
apply the WITH RECOVERY option. Reissue the RESTORE LOG statement WITH
NORECOVERY.
Server: Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally"

I tried several other things as well: backing up the current log and
restore it but it didn't work.
Please help or if this is not the right way to do this backup and
restore let me know how to do that. I really appreciate.
