Server 2012 using RDX Cartridges - Permissions - Access Denied

Currently, I am using a Windows Storage Server 2012 NAS with an Imation RDX USB drive connected for backups. I am using Symantec System Recovery Server 2013 to backup servers, one Server 2012 and one Server 2008 R2.  The RDX cartridge is being used for the offsite copy of the backup.

The Symantec Backup works successfully to the NAS, but when the offsite copy tries to connect to the RDX cartridge which is shared out, the connection to the share fails after replacing the RDX cartridges. This appears to be a Windows share permission issue with Server 2012. I can't browse through the network to the share. I get "you do not have permission to access...."


If I put an RDX cartridge in, and then remove the RDX share, and then recreate the share with full control for everyone, the offsite copy is created. The next time I replace the cartridge, the permission issue comes up again.

I have clients with this setup using Server2008 Storage Server and an RDX cartridge connected and I do not have this issue.

So I am wondering if Server 2012 security works differently and how to resolve this issue.

Thanks in advance.

how do you have the RDX device configured, in backup exec? just as a network share? i.e. \\mypc\D ?
Try mapping it to a drive letter on the backup server and configure it as a removable backup to disk folder

This is Symantec System Recovery Server, and not Backup Exec.  There are not removable backup to disk folders in SSR. Typically the destination is a network share so that a user doesn't need to be logged in to access the mapped drive.

Removing the RDX cartridge seems to break the share security in Server 2012.

What did Symantec Tech Support tell you?  When I've had RXD problems in the past, they were able to provide a hotfix.

Before you contact Symantec tech support, make sure you are running the latest RDX software and firmware.

Thanks Gary. I have not contacted Symantec because the security seems to be Windows based. When I switch cartridges, I am not able to browse in Windows Explorer to \\Servername\RDXShare. So Symantec would probably say it is a Windows security issue.  I did download the latest software and firmware.

Yes, Symantec might tell you to "talk to Microsoft".  But I think it is a little shortsighted to just assume that you're going to get a negative answer.

All I can tell you is that many of our clients use Symantec software, and over the years we've solved a lot of problems (and more than a few turned out to be "Windows issues") with a single call to Symantec support.  

But you have to understand the economics of a large global support organization like Symantec has - support calls cost money, and unresolved problems in competitive product spaces like backup software tend to cause customers to go elsewhere.

There are a lot of RDX units out in the world, so if this is a common problem, Symantec may have seen the problem and if they ahve seen it often enough they have incentive to create a workaround if possible or at least point you to a Microsoft or HP solution if one exists.

I'm not saying you shouldn't look other places, too, but the manufacturer can't possibly help you if you don't report the problem you are having.

Here's something to look at related to removable media in Windows 2012 - error message matches yours and it is related to removable media at least:

The resolution to this issue was that there was a mapped drive to the RDX share that was created on the server that must have been trying to keep a connection open to the original RDX cartridge. After swapping the cartridge, the security somehow was not allowing access to the new cartridge. I don't know the technical details on why, but disconnecting the mapped drive seems to have solved the problem.
