I am having an issue trying to figure out how getting a copy or backup of remote sites back to the main datacenter. In a nutshell, we have remote sites that backup to local internal attached LTO tape drives, we were told we can get a DASH copy or some sort of copy back to the main datacenter. I do not know how this is going to work… at all.
Here is the details of how we have things set up.
Datacenter – Commserve is hosted here. The media agent that is the intended target for the remote sites is here too. The media agent server is configured with SSD for the Global Deduplication Database and a pile of san storage on the back end for the library paths.
Remote Site – Remote site server is a host server with Microsoft HyperV role installed with 3 guest VMs. Remote server has an internally attached LTO drive (LTO4 or LTO5). The media agent is installed on the Remote server.
Storage policy configuration – Each remote site is set up with its own storage policy. These are not deduplication enabled. We do a full back-up each night, Monday to Friday to physical tape. The tape is changed out every morning by the remote site contacts. So we have Monday Tape, Tuesday Tape, Wednesday Tape and Thursday Tape. We have retention set to 4 days 0 cycles for the daily tapes. On Friday, we load a Week Set tape and keep an extended retention of 35 Days for these tapes.
What we have been told/sold by Commvault, and one of the factors in why we purchased it, was that we can somehow get a copy of the backups back here to the Data Center. I do not see or understand how this is possible with tape.
I have set up DASH Aux Copies for remote sites that backup to local disk drives, this is understandable, but I do not see how I can do it with tape. I do not know how to even begin to get our backup copies back here or even it is considered a backup copy...
I don’t think I can do a AUX copy from tape across the wire back to the GTC. Dedupe at the remote site is not there, so my guess is that it will send everything, even if it was possible.
I don’t know how to apply the seeding process to a backup to LTO tape. I just don’t get what needs to happen to do it.
I cannot set up another storage policy pointing back here, as a client cannot be part of 2 storage policies, plus I don’t see how that would work anyway
I am lost here and I have not had much assistance from our Commvault folks, sure I was on a call with them and they suggested CDR, which is not what we want to do.
I have like 90 sites that the company wants to get their backups back here, and I do not know how to do this….
If anyone out there has done something similar to what I am trying to accomplish, please let me know how you tackled it and how successful the results where.
If any more information is required, I can supply whatever.
