DeDuplication on a NAS Device

This issue has been solved. See solution.

Hello.  I am running Backup Exec 2012 on a Windows 2003 64-bit server.  I was previously using a tape backup that failed and so was recommended to backup to disk.  However; this disk device (NAS) is not large enough so when talking with sales people that are supposed to know my options, inlcuding Symantec, told me to purchase the De-Duplication option for Backup Exec.  So, I purchased it.  I couldn't get the services to start, so wiped it out and after much cleaning up after my original Backup Exec configuration, I had a clean slate and reinstalled Backup Exec 2012 and let updates run.

 

So, I am now in the confiugration process of my storage.  I go to storage and select the Disk Based Storage option, I have and select the Deduplication Disk Storage option, give it a name and here it then asks me for new, my only option is to select Local Storage, meaning internal disk to this server.  If I map a drive to this NAS device, it does not show up in this list.  So, thought I'd try the other option, put in the shared path to my NDX and get the following error "Network drives are not supported for deduplication disk storage.  Please enter a location that is local to this server."  angry

 

I am at my whits end!  How do I use this storage?  It's only purpose is to house backups and it was purchased with that in mind as it's a storage leader, a Quantum.   I stuck with Backup Exec as that's what we've been using, but starting to think that my only option is to spend more money again to try to fix this and toss Backup Exec and go with the Quantum software.

 

Looking for suggestions, step by step, or whatever it takes to get this storage to be useful.  Due to the failed tape drive, running out of room when moving to this and now the deduplication nightmare, my backups are non-existant.  I apologize for my tone, but completely frustrated.  Any help you can provide is greatly appreciated.

BackupExec Deduplication ONLY works with direct attached storage, and NOT NAS (CIFS/NFS)  This is stated in the read-me's, setup guides, and admin guides.

If your NAS can do iSCSI, that would work.

It looks from a quick search the NDX supports iSCSI. That is what you need to use to get dedupe to work.
Hopefully it supports MPIO, which you'll need too for best performance.

Thank you for your comments.  Guess was just frustrated and missing the boat.  I setup an iSCSI connection to the NDX8 and then was able to setup the deduplication option.  I am now resetting up my jobs so hopefully the rest works well going forward.  Thanks.

Like I mentioned, hopefully you even can get it to support MPIO, so you can get more throughput out of your device.  Fast disk is important for dedupe to be successful.
