To exclude replicated fs from NDMP backup

Gurus,

I recently meet a problem in backup on our DR site. We replicate(v2) some fs (both nfs&cifs) from Celerra1 to remote Celerra2, so there are two kind of fs on the remote celerra2 datamover - the replicated fs and it's own fs.

We use TSM on Celerra2 to backup the whole datamover server_2 so to avoid tedious works of configuring them one by one , however our goal is to backup ONLY the own fs of Celerra2 but exclude the replicated fs from Celerra1. TSM is using NDMP so seems unable to configure any exclude from TSM side.

I am wondering are there any parameters can be set on Celerra1 or Celerra2 so that the replicated fs can be excluded from the datamover that are being backed up? Could anyone share any idea?

Thanks.

    you just need to specify what file system you want to backup, for example here is the command that you can issue on TSM server:

    backup node SERVER_2 /root_vdm_5/apples,/root_vdm_5/oranges,/root_vdm_5/grapes,/root_vdm_5/pears mode=full toc=yes

    so this command runs from TSM server administrative scheduler, it backs up 4 file systems at the same time (MAX number of NDMP streams is 4 per datamover (datamovers with less than 8G of memory) ).

    Thx dynamox.

    We use backup node server_2 mgmtclass=ndmp_full toc=yes mode=full without specify a fs name hence it backups all fs in server_2. What we want is excludes some fs from this. eg, backup all fs except 4 of them- apples, oranges, grapes, pears in server_2.

    Hope I've made my question clear..

    Can you provide more details on how to configure exclude.fs.nas?

    also I'm thinking since TSM relies on NDMP, is there any parameter on Celerra side could be set to do exclude some fs....

    not sure how to exclude when you starting from server administrative schedule, when you start from a client you can configure "exclude.fs.nas"  option to exclude specific file systems.

    take a look at the backup-client guide

    http://publib.boulder.ibm.com/infocenter/tivihelp/v1r1/topic/com.ibm.itsmfdt.doc/ans50000.pdf

    i've looked through NDMP params ..don't see a way to exclude file systems, gotta do it on the backup client side.

    Does TSM support environment variables? If yes then you can pass exclusions to data mover using variables.

    Thanks and Regards,

    I'm currently working with emc to see if they know any para can be set on Celerra side, a bit strange I was asked to provide server_log though...

    Try setting the NDMP includeCkptFs param on the Celerra to see if it helps

    NDMP includeCkptFs

    Specifies whether config_get_fs_info includes ckpt file systems.

    0 = Exclude ckpt file systems.

    1 = Include ckpt file systems.

    If it doesn’t help I am afraid there isn’t much we can do from the Celerra side.

    IBM TSM is one of the few backup programs that don’t implement passing NDMP variables
