Error when restoring a backup of NAS share folder that are bigger than 1Gb

I'm getting the below error when restoring a backup of NAS Share folder. I observed this error when the file I'm restoring is greater than 1Gb.

But if I backup the same file locally I can restore it without error. Appreciate any help on this

Do you get the same when using recover?  Which version of NW is that?

Same error when using Recover.

Initially I'm using version 8.2.2.6, then thought its a hardware problem. I replaced the library with new one, still getting the same error. Tried to update/upgrade to version 8.2.3.6 but still same problem.

1GB is not much so perhaps I can retest it.  So, you have some NFS share right?  And there if file is bigger than 1GB backup works fine, but restore doesn't.  When you do restore, do you restore locally or back to NFS?

I tested both scenarios and it worked just fine for me (8.2.3.7):

Re: Error when restoring a backup of NAS share folder that are bigger than 1Gb

I did another testing today.

I create a shared folder on one of my Windows server and copied a big file in the shared folder.

I backup the file using full path \\server name\share folder in the save set, and I was able to restore it.

On my NetApp Filer I created a new volume, create a share folder and then copy the same big file.

I backup the file using full path \\filer name\share folder in the save set, but I got the same issue when restoring.

Re: Error when restoring a backup of NAS share folder that are bigger than 1Gb

Ah ok, you are using CIFS... didn't test that one.  Well, one thing is that you should use NDMP with filer appliances and not CIFS (while it should work, that has always been official approach to backup of filer appliances and in general CIFS was supported only when NDMP was not available).

The fact that it works with normal server and not with filer itself may suggest issue on filer side (I guess you checked for any quotas).  And just quick google around gives you next clue:
