Snapshots
This will provide a great option for scheduling consistent EBS snapshot. The agent uses VSS (Virtual Shadow Copy Service), which ensure the consistency of every file in the EBS volume.
Before a snapshot is taken, the agent will send a signal to other applications such as MS SQL Server to quiesce the OS for a few seconds, take the snapshot and release the system. This process ensures that all files on the EBS Volume being snapshot are in the same state.
