How to backup EMC Storage with Backup Exec (using snapshot)?
Hi Experts,
Our office has just gotten a DELL's EMC SAN, and I am finding a way to backup data on the EMC. The initial setup of the EMC was done by the Dell's technician, but as for the backup part, we are repsonsible for that. As far as I know, the EMC will be divided into many LUNs and attached to different servers.
I just want to see if any one here have done backup on EMC, and how have you done that? We will be having files and MS SQL installed into those EMC's volumes, so I want to make snapshots, backup the data, and then remove the snapshot. Anyone can reference me how that is done?
Thank you very much.

Check into the ADBO option for Backup Exec, which can interface with the Clariion.

Hi Saiprasad,
Thanks for the response... what you say is that I mount the LUN to the backup server and do a backup like the LUN is a local drive letter? But what if the LUN contains DB files on a SQL server? Then, I think backup exec will back them .mdf, .ldf files as files instead of DB (even though I have SQL agent license).... my manager wants me to make a snapshot out of the LUNs, then backup the snapshot... that way, when comes to restore, the chance of recovering maybe greater...
Hi Honmapog... thanks for you assistance again.. you may rememeber from the equalLogic question? Yes, we have new SAN... both equalLogic and EMC. Does the EMC works just the same as the iSCSI SAN? can backup exec also create a snapshot, backs it up, and the removes it like equallogic can do? thansk

hi, yes for the first question however as you said you have the db on one of those LUN,s and i hope you have SQL agent and ADBO option installed( if you want to use backup exec snapshot option) then my answer will not be correct,
if you want to use EMC navisphere to perform snapshot then you will certainly end up taking them as mdf and ldf and not database, the possiblity of performing database backup snapshot will be using both sql agent( to view the mdf and ldf as databases ) and ADBO to perform snapshot.

I tried to do a backup from Backup Exec using the ADBO & SQL agents, but it returned a exception saying:
Backup- SRCH106V-79-57344-34086 - ADBO: Offhost backup initialization failure on: "SRCH106".
Snapshot provider error (0xE0008526): Backup Exec could not locate a Microsoft Volume Shadow Copy Services (VSS) software or hardware snapshot provider for this job. Select a valid VSS snapshot provider for the target computer.
Check the Windows Event Viewer for details.
I tried in on equalLogic iSCSI SAN, and I was acutally could see snapshot being created and deleted in the event log, which I think worked well. but how do I confirm or know whether snapshots are acutally used?

Gentlemen, thank you for your guide-through. My teamate figured out a way to backup snapshot of the EMC volumes without using the ADBO Option. What he did was
1. use Replication Manger to create a schedule job to take snapshot. (but disable it from running, just need to have a job created which we can call)
2. In backup exec, pre-job command line, call the schedule job from Step 1 to run. This kick-starts the snapshot creation and mounting on backup server
3. Acutal Backup
4. Post-command script, create a batch file that use the "rmcli.exe" command line interface to unmount and destroy the snapshot.
we've done tests for 2 nights... so far so good. Thank you for your input, i will see if that makes things easiler when I have time to do more testings with it.

all you have to do it either map the LUN's locally to backup server and assign a driver letter if all you want to use those LUN exclusively for windows N then use backup exec to backup your data.
this way you will be able to achieve LAN free backup and which will give you good throughput as well.
Secondly you need to install different agents to perform the backups like SQL agent for sql database backups, to backup windows you need client agent and etc..
you can refer to backup exec guide to check how to perform backup to disks.
hope this helps
