Backup question

Hi All!
I'm rather new in AIX so I want some comments about backup scheme I've developed to backup every part of the system. I have the following hardware:
- Power6 570 server with two VIO server and 3 LPARs
- NIM server outside (on the other Power server)
- Windows 2003 Server with Tivoli Storage Manager 5.5.2 Server and TS3100 Tape Library connected by SCSI (we have planned to backup only DB2 on the tape, because we don't have any backup software except TSM API for DB2)

VIO server 1.5.2 FP11 SP1
LPAR - AIX6.1 TL2

I have installed this software on LPAR:

LPAR1 - WebSphere Message Broker
LPAR2 - WebSphere Application Server
LPAR3 - DB2 9.1

Now the backup procedures. I included restore methods in ().
1) HMC - Back up HMC Data - backup by FTP, and then burn to DVD (restore: Install HMC from shipped (or downloaded) CD and then restore this backup into HMC)
2) VIO server:
- rootvg - backup by backupios commend into nim_resources.tar on file system mounted by NFS, then burn to DVD (Restore: by NIM server. As I've read AIX 6.1 supports install from nim_resources.tar, not only from mksysb)
- hdiskX (on them are LPARs rootvg volume groups installed) I don't see any reason and possible methods to backup them. LPAR rootvgs are backed up later. So I think it's enough.
- !Question! Should I do savevgstruct for this hdiskX? Actually I didn' get what is the use this command... As I understood, after restoring from mksysb (done by backupios) LPARs rootvg all information about other volume groups, user settings and virtual device mappings should be restored also.
3) LPAR:
- rootvg - back up by NIM server (mksysb), and burn to DVD(Restore: by restore command from NIM server)
- for WMB and WAS partitions I want backup shared volume group on which WAS profile and message broker archive files placed by savevg command, because they are simple files. Burn images to DVD. (Restore: restvg)
- for DB2. I have enable "Archive logs" for DB. Logs are backed up by TSM API to the TSM Tape Library. One time in week I want to do full DB backup. !QUESTION! Should I do incremental backup every evening? Or in case "Archive logs" I shouldn't do that? (Restore: by means DB2, firstly restore full DB backup and then restore archived logs.)

Please comment this scheme. Will be these backups enough to restore every part of system? I'm afraid that I missed something...
P.S. All rootvg volume groups are installed on internal server disks. DS4700 contains LPAR user defined volume groups. DS4700 have an option VolumeCopy enabled but I don't see any ability to use it in my scheme. Or may be I just didn't get the meaning of this feature. Is't possible to use VolumeCopy in any step in my scheme?

Any comments are appreciated!
Thank you in advance!

BACKUP_DELVOLSET(8)					       AFS Command Reference					       BACKUP_DELVOLSET(8)

NAME

       backup_delvolset - Deletes one or more volume sets from the Backup Database

SYNOPSIS

       backup delvolset -name <volume set name>+ [-localauth]
	   [-cell <cell name>] [-help]

       backup delvols -n <volume set name>+ [-l]
	   [-c <cell name>] [-h]

DESCRIPTION

       The backup delvolset command deletes each volume set named by the -name argument, and the volume entries each contains, from the Backup
       Database. The backup listvolsets command lists the volume sets (and their volume entries) currently defined in the Backup Database.

CAUTIONS

       Deleting a temporary volume set is possible only within the interactive session in which it was created. Exiting the interactive session
       also destroys the temporary volume set automatically.

OPTIONS

       -name <volume set name>+
	   Names each volume set to delete.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
	   the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
	   details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command deletes the volume set called user and all volume entries in it:

	  % backup delvolset user

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
