NDMP Backup of Isilon, and using wildcards

[bunsen82]

Hi,

I have researched online and while I have found some answers, I am not getting the result I need.

I am trying to create a "wildcard" selection to my NDMP policy, backing up EMC Isilon. Ultimately, I want to backup all folders in one stream that start with A, the next one B and so on.

My stream for A reads like this:

NEW_STREAM

/ifs/Archive/Folder/Folder/A*

However I am getting error 106 invalid path name and I am getting the same error for all wildcard streams. I assume I have missed something, can anyone advise?

Thanks!!

The thing to remember is that NDMP is not a file system, it is a transport protocol.  What this means then is that vendors internal volume and file system structures are carried by NDMP protocol.

So, I think your problem is possibly around the level/depth of the path that you are specifying... and so I suspect that the Isilon itself is unable to create a snapshot at that level.

e.g. my conjecture, and I have no actual experience of this, is that these two object paths point to different object types...

1) /ifs/Archive

2) /ifs/Archive/Folder/Folder/A*

...and so I suspect that 1) is perhaps a volume level object for which an snapshot for an NDMP backup can be established, and perhaps object path 2) points to a "folder" but that the Isilon OneFS file-system and operating system is possibly unable to establish a snapshot for NDMP purposes on a folder.

.

My question to you is... have you checked the Isilon documentation to prove that the object type/level/depth/naming-structure of "five levels deep" that you are attempting to use... is even supported to be used/specified in the directive list for an NDMP style backup job for Isilon family of NAS appliances?

Unrelated to your question, but possibly useful background info for others:

my understanding is that NDMP wildcards are based on tow things - the NB version, and the NDMP filer.

Some support wildcards, and SOME DO NOT! You should check with EMC regarding the isilon, I know we had to upgrade ours to enable wildcards.

Hi,

We are able to backup succesfully from the Isilon via NDMP. The work I am doing is trying to break down the policy as currently the stream is too large.

If I create a stream for /ifs/Archive/Folder/Folder/AFOLDER I am able to succesfully backup the data. This is the case for any folders on the Isilon in any location when I apply a specifc include/stream. Its only when I try and implement the wildcard config that I get the 106 error.

Ok, we are using NBU 7.6.1 with Isilon 7.2.1.2 - I will do some further research into the Isilon compatability
