NFS share backup through linux media server to VTL

Hello All,

 

I need to backup my NFS share mounted on a Linux host (media server) and write the backup onto the VTL (StoreOnce). My master server is on windows 2008 platform.

I have succesfully mounted my NFS share onto my Linux host. However when i take a backup, i get an error mentioned below:

None of the files mentioned in the file list exist or may not be accessible(71)

 

1. Do i need to zone my linux host along with the WWN's and the master server in the switch?

2. How do i create a storage unit and policy for this type of configuration? What should be the entries/selections for the same?

 

NBU version: 7.6

 

Any inputs appreciated.

thanks!!

    Did you select the option "Follow NFS" in the policy attributes tab...?

    to take the backup of NFS shares.. this option needs to be selected in the policy..

    if not please select it and try again.. let us know the results..

    I agree with Nagalla.

    Double-check that root on Linux media server has read access to the NFS share and execute permission on folders. Execute permission is needed to cd into directories.
    Test with:
    # cd mount-point
    # ls -lR

    You can CTRL-C if lots of output is displayed.

    Rest of config will be same as any other filesystem backup on the Linux server.
    Have you already created STU for the VTL on this media server and tested filesystem backups?

    This is not an ideal setup. I would not recommend using an NFS share for the source or a VTL for the destination. It would be best to do a backup directly from the source to a disk pool. You have added multiple layers of complexity that add failure points with zero benefits. 

    Maybe we can help you with the problems you faced that led up to this configuration?

    Solving those problems would be better than solving this one.

     

    1. Why are you using an NFS share instead of accessing the data directly?

    2. Why are you using a VTL instead of an advanced disk pool?

    I tried this option by selecting Standard as policy type and selecting Follow NFS. However, the backup still fails. :(

    Yes Marianne, Full permssions are applied. Backup fails even with Follow NFS option selected.

    I'm not sure where these requirements come from but you can tell them that this is a bad idea. It can work but this is not a secure way to protect your data.
