How deduplication replication and duplicate to tape

I have 2 backup exec server 2014 in different location and connected using private link (40mbps).

On main site, there is CAS with deduplication disk.

On second site, there is MMS with deduplication disk and tape library.

I try to create a backup job on CAS but cannot select tape as duplication destination.

It need to share library across server or not?

OK the CAS runs the initial

OK the CAS runs the initial job to it's own deduplication storage and the job to duplicate from the storage on the CAS to the shared deduplication storage on the MBE. However because the CAS cannot physically access the tape drive, the MBE has to run the second duplicate stage to get the data onto tape, hence why you would need the MBE to be responsible for that job.

 

So Job Stages ( would be )

- CAS server runs job to backup the initial data to it's own Dedupliation Storage Folder

- CAS server runs a duplicate job to copy the deduplciated data form its own storage to the shared deduplication storage on the MBE server (the CAS server can do this because the MBE storage is shared)

- MBE server then duplicates the copy of the backup that is now it its deduplication storage onto the atteched tape. (this job is still created in the console of the CAS server  you just tell it to run on the MBE)

 

For the above to work the MBE MUST be designated as a Private Cloud server and its deduplication store MUST be shared to the CAS at the main site.

 

Note: we do normally recommend that the CAS is at the remote location with the attached drive and not the MBE but as long as the private cloud option is used it should be possible with the MBE remote.

The tape library must be

The tape library must be connected directly to the CAS before it can be shared.  Also you would need to install SSO.

I just wonder that SSO

I just wonder that SSO included in CAS or not?

However the tape library is connected to MMS and unable to share because there is no SAN between servers. So how to duplication across site and save data on tape?

In BE 2014, SSO is part of

In BE 2014, SSO is part of the Enterprise Server Option (ESO) which also includes the CASO.

In order to get CASO, you

In order to get CASO, you would have bought ESO and this includes SSO.

You need to have a separate job on the MMS to duplicate the backup set to tape.  You cannot do it from the CAS.

In your initial

In your initial scenario

Assuming you backup to the Deduplication folder on the CAS first then you would run a (optimized) duplicate job to replicate the data form the deduplication folder on the CAS to the deduplication folder on the MMS/MBE and then run a duplicate job on the MMS/MBE to get the data onto tape.

to get this to work you would need to share the deduplication folder on the MMS/MBE to the CAS and also enable the MMS/MBE as a private cloud server 

C.

I can set up optimize

I can set up optimize deduplication but cannot select tape device as destination.

Did you find and set the

Did you find and set the "private cloud" setting against the MMS/MBE server? Note: this is not a job setting this is a server setting (possibly set in the console of the CAS server against the MBE somewhere in the CASO-MBE communication settings)

Also in that second duplicate storage I think you have to specifiy that the job should ONLY run on the MBE server (in the job settings)

 

As an aside - the name of your server appears 6 times in your screenshot and you have only hidden one if the instances of the 6. It is also a generic word that loads of different companies use for a specific type of server, so not sure why need to hide it. Only mentioning this so that in the future if you have non-generic servernames that you do need to hide, you realize that a bit more care may be needed to hide it.

I need job run on CAS because

I need job run on CAS because it's in same site with client but run duplicate to tape at MBE on another site.

What happen when select job run on any server? How Backup Exec choose server to run the job?
