Transactional Consistency SQL/Sharepoint

Post by gingerdazza »

In an environment whereby you have a SharePoint VM, a SQL VM, and perhaps even a VM for BLOB storage, what tactics can be employed to keep the entire SharePoint stack transactionally consistent? This seems quite a difficult objective without storing all these VMs on the same SAN LUN and using SAN snapshots....

You would need to freeze SharePoint farm activities first (via some pre-job script), then backup all VMs simultaneously, and finally unfreeze SharePoint, once the snapshots of all VMs are taken.

The other alternative I can think of is to have the entire sharepoint stack of VMs in a Zerto VPG. (Sorry if that five letter word is blasphemous round here) :)

....this makes frequent SharePoint PIT protection verrrry difficult. You can't be having hourly outages :)

Another point is that we support only BLOBs with Microsoft RBS FILESTREAM provider, which can be used either locally or via iSCSI.
