How does instant recovery (recovery-in-place) work?

What is recovery-in-place, which some people call instant recovery, and how does it work?

Oh, recovery-in-place. I tend to hear people refer to that a lot more often as "instant recovery." The basic idea behind that is that one of the big barriers to disaster recovery is the amount of time it takes to recover data.

In the past, there was a really long wait while data was restored, so instant recovery -- or recovery-in-place -- sought to eliminate that recovery window by redirecting the user workload to the backup server.

Now, you don't want to connect the user directly to a backup copy of their virtual machine because the minute the user starts working on that backup virtual machine the backup is no longer in a pristine state.

So what happens instead is a snapshot gets created so the backup remains in a pristine state and all the user write operations get redirected to that snapshot, so users are able to work off of the backup virtual machine.

As soon as that happens, the recovery process begins in the background. Users are completely oblivious that the recovery is even going on, and once the recovery is finished, the user workload is redirected back to the original VM.
