Replicated NDMP backups to secondary site for restoration

Running NetBackup 8.2 on appliances.

We have taken backup of NFS shares using NDMP methodology in one site and replicated to secondary site. However we don't have any filers yet on destination site. Would like to restore few of the files from this backup to a regular linux client, but restore is failing with "allocation failed"

An backup of type NDMP can be restored only to an NDMP servers ?

Yes. NDMP backup policy can only restore back to same manufacturer NDMP server.
I believe this is documented in NBU for NDMP Admin Guide.

If you want to restore to regular Linux server, you need to take Standard backup of NFS mounts via a Unix/Linux client or server.

TN:
NDMP Backups are hardware dependent. Restores to other NDMP devices or Operating Systems will fail.

The destination host must be an NDMP host compatible with the data format of the source. (The source and destination must be of the same NAS vendor type.)

Re: Replicated NDMP backups to secondary site for restoration

Thanks for the response. So the destination has to be of NDMP type and also from the same vendor.

And we can't even restore to a different vendor (though it is in hcl of NetBackup)

Re: Replicated NDMP backups to secondary site for restoration

Restore to different NAS manufacturer is certainly NOT in the HCL.

Any kind of supported filer type (in HCL)  can only be restored to the same filer type.
This is due to limitation from the NAS vendors, not Veritas.

Re: Replicated NDMP backups to secondary site for restoration

That's always a popular question when it comes time to change vendors too. "Can't we just restore the old backup onto the new NAS box ?" "No." "Why not ? It's just a backup !"
