I have a procedure for daily snapshot of EBS without unmount the volume from the EC2 instance. This volume is not the root device and the snapshot is performed without stopping/freezing the filesistem, therefore the file system integrity and the snapshot consistency of snapshot is not guaranteed.
Unfortunately I cann't stop the server.
I have some doubts with the "consistency":
- The consistency refer to the ability to restore the snapshot?
- I can't create a volume from inconsistency snapshot?
- If a snapshot is inconsistency, all successive snapshot are inconsistency?
