Backup VNX CIFS share - Whats the best way?
We are starting to use CIFS file shares off of our VNX SAN. There appears to be 3 ways to back this up, either by backing up the CIFS share directly, mounting it to a server and backing it up, or using NDMP, which requires an agent.
I just setup NDMP and tested it. Works very nice, however I see that you cannot redirect a restore to a non NDMP device?? Is there any trick to get this to redirect somewhere else? I don't understand why this is not possible. I don't have anything else to redirect to, so if for some reason part of the VNX that makes the CIFS work goes down, my backups will be useless until it is fixed. I have a Data Domain from EMC as well, but I don't see that I can make it an NDMP device.
CIFS direct or indirect seems to be a pain. Port 10000 is used for both NDMP and the BE agents, so I actually have not even tested this. I can't figure out how to turn off NDMP on the VNX yet, and I think that is the problem. I'd imagine a CIFS backup would be tripping over a lot of open files possibly?
I'd like to do a combination of both. Maybe a CIFS backup once or twice a month, but have the NDMP be the primary method.
Can anyone offer any input? The only thing stopping me from going all NDMP is that it seemingly can't be redirected. If we had another VNX or Celerra, I wouldnt worry, I just like to have a good plan B in place.
