EBS snapshots on Windows EC2 instances are not application-consistent by default. So, if you’re backing up databases running on EC2 instances while you are “online”, the restored EC2 instance or EBS volume will require you to run a “consistency check” —which can take hours and sometimes result in an unusable database.

That’s why, with N2WS Backup & Recovery, you can implement application-consistency for your databases running on EC2 and remove the need for additional consistency checks (which directly reduces RTO).
