How to backup from SAN to tape library?

Created: 09 Oct 2012 | 20 comments

Hello,

Please can someone tell me how to backup in symantec exec backup 2010 from SAN (storage area network) to tape backup? I am not seeing SAN on backup server but I am seeing my tape library on device manager!

Any help would be really appreciated.

Hello Rocky,

    What I understand from the information is that you have data on the SAN storage and that needs to be backed up to Tape drive.

For that Map a LUN to the Backup Exec server and give Drive letter to the Mapped LUN through Windows Disk Management. Then create a job of local server and you will be able to see the Mapped LUN in the selection list. Select the data for backups and target the job to the tape drive.

This will backup your data from SAN to Tape drive.

 

Thanks,

1) LUNs that are assigned to media server from SAN device can be backedup directly. But, unless the servers are part of clusters, LUN can't be assigned to more than one server at a time.

2) If you have Cloning feature (licensed generally) with Storage device available, clone the volume that needs to be backedup to tape, assign it to backup server and back it up. Available free space within the storage array might be a concern here.

3) If you have Snapshot feature available with Storage device, take a snapshot of the volume, assign it to backup server and take backup.

4) Purchase Advanced Disk Based Option from Symantec and use Offhost Backup Feature from Symantec.

Thank you to both of you and yes one of the servers is cluster. I will try it and let you know the status. again thank you very much Sush and Kiran

yes one of the servers is cluster.

How many number of LUNs you need to backup from SAN and to how many servers those LUNs were assigned with? 

If you have only one cluster or one server assigned with all the LUNs then purchasing another media server license and SSO license is Ok. But if you have LUNs assigned with more servers then, you will end up purchasing that many number of media server licenses. Personally i am not a fan of this approach, as installing media server software on production servers does put a bit more load on them.

You might not be a fan but it works, hence the reason for SAN SSO. If you have a cluster, chances are great that you have the "grunt" behind it anyway. SAN SSO is going to work out a lot cheaper than array snapshot software; it's going to be easier to implement instead of having to script LUN presentation etc; and easier to manage from 1 environment.

SSO is cheaper than Snapshot license, easy to implement no need of scriptinng. All known facts and i never said anything against it.

But SSO is not individual. Media server must be installed on all the servers that have access to LUNs from SAN. What if customer have more servers assigned with SAN Luns that needs to be backedup? That is what i am trying to confirm from the OP in my earlier post.

With more numbers assigned with SAN LUNs, licenses for SSO, Media Server along with CASo would be costlier than all the alternates i mentioned, i.e Snapshiot, Cloning and ADBO. And most importantly any of the three license would do the job for OP. 

Now OP can decide what to use depending on number of servers.

So you have done a costing on this? Good to know wink

one more thing, do I need any licenses for SAN as well or not?

If you only are mapping SAN Luns to the meda server and backing them on a local Tape drive, NO you dont need a SAN - SSO license.

The OP stated he has an Exchange cluster!

Craig, agreed that Exchange is a cluster, how does SAN SSO help here. Backup Exec Exchage Agent is fully capable off backing up the Exchange Cluster. If he needs to perform an off host backup( Transfer the SAN Snapshot to the Tape directly without BE coming in to the picture), then Advanced Disk Based Backup Option is the way to go. However, in this situation the Tape Drive needs to have direct access to the SAN (via Fibre)

I take it you haven't worked with SAN SSO? You guys are mentioning LUN cloning and LUN snapshots and ADBO. SAN SSO will do the same thing.

You should know how it works so I won't tell you how it does...needless to say: Exchange servers attached to SAN & backing up to SAN-attached tape library = SAN speeds for backups! wink The rest is very self-explanatory!

...the OP has still not clarified whether or not his tape library is SAN-attached. If it, then SAN SSO will work. I am fully aware of the requirements for SAN SSO having implemented if before. It works well.

@Craig,

Where OP mentioned about Exchange Cluster? Am i missing some posts in the discussion?

Sush...'s picture

Even I do not see anything mentioned about Exchange Cluster here by OP...

Seems like I am not quite correect on that 1!

Hi,

 

You need 1 license...SAN SSO. Since you already have a cluster, and as long as your tape library is also connected to the SAN, you can end up with a LAN-free backup. It works well, I have used it before, and have seen jobs cut by more than half.

You will need the following:

1. 1 x SAN SSO license for BE 2010 Rx. This is installed on your media server and you run the SAN SSO wizard.

2. 2 x media server licenses for your cluster nodes (if you don't have this already), and any agents if the cluster runs Exchange/SQL etc.

What SAN SSO does is share the SAN-attached tape library with other servers on the SAN running full installations of BE, and allows them to access the library directly. SAN speeds would be faster than your LAN in any case.

Cloning, licensing SANs to do snapshots and ADBO aren't necessary in this case at all.

Read about it on the links below (the Admin Guide also has a bit more information):

To answer to these question: "If you only are mapping SAN Luns to the meda server and backing them on a local Tape drive, NO you dont need a SAN - SSO license"

Yes the plan is to map SAN Luns to the media server and backing them on to Tape drive; in that case, as every body mentioned, i don't need SSO license, right?

Sush...'s picture

That is Right. If you are Mapping the LUN and taking backup to the local tape drive as I have mentioned in the first post then you will not need the SAN-SSO License.
