Re: Testing in AWS, EBS

Why no? Or you missed something?

It should be done on every EBS restored from snapshot.

Is that from your personal experience, and if so, when did you do the test??

Yes we are using this practice, because as a part of our production load we
are using auto scale groups to create new instances, wheech are created
from AMI, wheech stands on snapshots, so...
