  • CV Backup directly from Storage Snaps?
    Posted: 07-12-2019, 8:44 AM

    We have been using CV for years, and recently due to a new storage, wanted to utilize storage snaps for backups to increase the speed, and allow us to snap some rather large VMs (20tb) that we have not ever been able to snapshot within vmware before without it freezing the machine for a long time. 

    We are testing another brand of backup software, and it basically does a quick snap of all the vms, then releases those snaps, then does the storage snap, and backs up from the storage from that snap directly. 

    CV on the other hand, does a VM Snap (looks like a normal snapshot to me vs the other software), and then releases the snaps, but then does a storage snap and that's it.  Then a Backup Copy is ran immediately or later, attachs that storage snap to the VM environment and then attachs those machines to the VSA Proxy machines and then backs them up across the vmware environment then to the media agent instead from the prod storage snapshot directly to the media agent.

     

    CV media agent has full access to the prod storage just like the other software too.  With the way CV does it, it doesn't seem to be any faster other than causing us a bunch of alerts that a datastore is offline or added, and no performance benefit as it took the same amount of time as it does currently. 

     

    Does CV not do it like the other software does at all?  Is there another way to configure this to make it work like that?  I have had no much help from CV support other than them saying this is the way it worsk.

     

    Storage: EMC Unity 400f, Fiberchannel.  All Zoned to MediaAgent.

    what you want to use is Intellesnap

    Its pretty awesome to use. SNap from the SAN then the it sends that backup to the media agent. The backup is quick but the copy can take a few hours. 

    Here is some great info on it:

    Yes, it is great.  We finally got it working properly.  The first engineer we were dealing with didn't know squat.  So when I got another engineer, he knew his stuff.  We forced to use our media agent as the proxy, instead of it using the VMs as proxies as that was the bottleneck.  Once we did that, everything started to work and we were getting 1500-2000gb an hour for transfer rates!!!  So awesome.
