Volume Shadow Copies and Normal Backups

Hello Experts,

I have a question that I can't seem to find a whole lot of information about. We have Volume Shadow Copies running on all of our 2008 R2 Files Servers that take the standard snap shots at 7:00am and 12:00am daily. We also are running a Master backups of those servers with Incremental Forever backups after that to a Unitrends Appliance, and then from there replicating to the cloud. My first question is it best practice to have Shadow copies running in conjunction to your normal backups, or should these be disabled?? The other question is it bad to have both running?? In other words will the two services also compete with one another? Any help would be greatly appreciated, and if you don't mind could you please explain your reasoning that you give to each question.

The two are complementary and are meant to solve two different issues. As long as the backup product you are using is VSS aware then there won't be a conflict. Shadow copies provide a self-service way for users to revert to an older version of a file without involving IT if they find they made a mistake. Backups, on the other hand, are more useful in the event of a massive failure such as a physical hardware failure, a full site outage, or other destructive event such as a mass cryptolocker event. So both have their place and running both can be worthwhile in the right circumstances. But each network is different. If you never see staff using shadow copies to recover files themselves or if you prefer all such requests to go through I.T. then by all means, disable shadow copies. It'll make a performance difference and save some disk space.

Good Afternoon Cliff,

I appreciate your extremely fast response. Sorry I am just now getting back to you though.

Your response answered everyone of my questions in full, and I thank you for the detail that you gave. We never have any of our users trying to restore files on there on, so I think it would suite our needs better to just disable Shadow Copies entirely. Hope you have a great rest of the week.
