Backing Netapp CIFS share using TSM

Hi All,

We have a requirement of backing up the Netapp cifs share using TSM. I know we can do it by mounting the cifs share to the windows node. I have windows node ready and my windows admin is getting the share ready by mapping it as one of the drive on that windows node. i want to know how can I do that, also I want  to send the backup directly to tape instead of disk pool. kindly help me in doing that. TSM client would be 5.3.3. and OS windows 2008 R2.

Thanks

I've had mixed results backing Netapp CIFS volumes by mounting the windows share.  You may want to see if you have the NDMP agent available and use it to backup the volumes, it is Netapp's native protocol.

Hi Paul,

can you elaborate more on this - mixed results means...can you share the procedure for the same.

I haven't used with TSM specifically but on some backup software packages I can mount share as a windows share and some cannot.  For the ones that I cannot I have always had to use the NDMP agent which is the only one supported by Netapp.

I am trying to use "resourceutilization" parameter in client options files. I have couple of questions on this, if somebody can answer, that would be of great help :

1. I can start multiple backup stream for a single netapp share using this parameter, but I am not getting any throughput improvement. But whether it helps to finish the backup early as compared to single backup stream - is that right ?

2. Multiple streams means single file is backed up to 2 or more tapes...or....different files are backed up to 2 or more tapes.....

above are the questions which I have.

Are you backing over the network?  If so and you're connecting to one ip address then you'll not get any greater throughput.  the reason for this is how your VIF is setup.  If you're using etherchannel (cisco) or lag (hp, dell, etc..)  then it's a many to one or one to many protocol but your session cannot go above a physical nic port since a session can't use multiple nics.  

The way I can see this is if you have multiple IPs for different shares, this way you can setup multilple backup jobs using different sessions.

So, if I have to implement NDMP + TSM, what things I need to consider. Do you have any step by step procedure for implementing it. I have FAS3170, TSM server 5.5.0.0 and L3494 IBM library. Currently, my TSM setup is in working condition. Now, if I want to use NDMP to backup the CIFS shares, what would be the starting point for the same.

If you do not have NDMP you can try to give Netapp a call and see if it's perhaps a permissions issue and you need to configure the backup service account on the Netapp for the correct permissions.

With NDMP typically you add the Netapp as a NDMP device and the backup software uses the NDMP agent to browse it and allows you to perform backups.  I have worked with several vendor software packages but TSM is not one of them.

I see NDMP is enabled on my FAS3170 filers and TSM client does support NDMP. So, can you let me know how the setup should look.

As of now, I am using tsm client on windows to access the cifs shares and taking backup using tsm client by using DOMAIN \\servername\share1 option.

Yesterday I enabled SMB2 on my netapp controller as recommended by NetApp, so the shares got enabled for smb2, but now I am facing a strange problem, some of the shares are getting backed successful, but other shares are getting failed. Somehow, it is appending "\" at the end of the share i.e.

\\servername\sharename\, and due to this it is giving error. can some one help me out in this ?

So, I configured my TSM client to use resourceutilization parameter and now my backups are running fine as well as they are getting completed in expected backup windows. So, closing this question and giving points.

I figured out that by adding resourceutilization parameter value to 10, I can start multiple backup threads at the same time so that the backups finished with the expected window.
