BE2012 WAN optimized deduplication with a communication or Central Adminstration Server (CAS) failure
Version 14.0 1798
I’m having trouble getting past some issues with this structure. It comes down to either optimized deduplication works, but I can’t use the MBES/MMS when the CAS is down or both sites are fault tolerant but I can’t setup optimized deduplication between them.
My goal is to use optimized/shared deduplication to replicate server backups between my two sites and be able to restore those backups and local backups during a vpn failure or site failure. If site A is down, I want to recover site A servers to site B. If site B is down, I want to recover site B servers to site A.
I thought that I could place a Backup Exec 2012 server at each site and use optimized deduplication for this, but I ran into a few problems. Optimized deduplication, or shared deduplication as it is now called, seems to require the Central Administration Server Option and this has the following options for its Managed Backup Exec Servers:
1. Centrally managed Backup Exec server
1a. Centrally managed Backup Exec server with Unrestricted access to catalogs and backup sets for restore
2. Locally managed Backup Exec server
Options 1 & 1a:
With the “Centrally managed Backup Exec server” option chosen for the Managed Backup Exec Server. Having a CAS with a deduplication folder at site A and a MBES with a deduplication folder at site B works and staged jobs will run from one deduplication folder to the other. The problem here is that if the CAS is down or the VPN is down, I can’t even bring up the BE2012 console on the MBES let alone run jobs or restores. The MBES is totally dependant on a persistent communication link with the CAS under the “Centrally managed Backup Exec server” “Managed Backup Exec Server Configuration” option.
MBES that is a “Locally managed Backup Exec server”. While the CAS and MBES can still function without each other under this scenario, I can not share the MBES deduplication folder with the CAS. So I can’t do optimized deduplication between the two.
Am I wrong about optimized deduplication requiring CAS + Centrally managed Backup Exec server? If so, please explain how to set it up.
Is there a way to use the Centrally managed Backup Exec server when the CAS is down? I don’t understand how I’m supposed to recover if the CAS is gone.
