DLO and maintenance servers

This issue has been solved. See solution.

Hello,

I'm using Desktop and laptop Options on backup exec 2010 R3.

Our company is divided in two different buildings (lets call them site 1 and site 2) with an EMC storage on each.

For the moment, all our DLO users (about 50) are backing up their datas on site 1. The backup exec server is on this site as well.

I'd like to create two separated storage, one on site 1, and one on site 2, in order to lower the impact of the DLO on my inter-site link.

I read in the Backup Exec documentation that a maintenance server is needed if you use delta file transfer.

So, I did the following for test:

    - created a virtual machine on site 2

    - installed the maintenance server on it

    - imported the new maintenance server in the DLO console

    - created a new storage location on site 2's storage and associated it to the new maintenance server

    - moved the datas of a test user on the new location

As I was not really sure of the whole procedure, I skipped the Active directory delegation step but the agent seems to copy the datas of my test user whithout any problem on the new location.

     - How can i check that my new maintenance server is working fine and that it's used by the agent for delta file transfer?

     - What sytem requirements (processor, OS, etc...) would you advise for a maintenance server?

Thanks in advance for your answers.

The maintenance server grooms files, i.e. it limits the number of versions of a file in the NUDF (Network User Data Folder in storage location) to the number provided in the profile. Without the maintenance server grooming will not happen, so the number of revisions of a file keep growing beyond given limit.

This can be verified either by going to the NUDF or from the restore tab in the agent.

If the limit exceeds then delegation between the maintenance server and the storage location needs to be provided.

 

When a Maintenance Server is pushed to a remote machine, the machine on which the Storage Location is present needs to trusted by the Maintenance server machine.

Here is how to add the trust.

Locate the Maintenance server computer on the Active Directory in the Domain controller.

Right-click > Properties > Delegation (Check attachment)

Choose the two options (radio-button) as indicated above and then add the computer on which the storage location exists. CIFS (Common Internet File System) service on the SL machine needs to be added to the list of trusted services.

Only after these settings are confirmed does a Maintenance server groom files.

     - What sytem requirements (processor, OS, etc...) would you advise for a maintenance server?

Check attachment for details.
 
We hope the above information proves instrumental to you.
