Is file created by consul snapshot save is encrypted? If no, how can we encrypt it?
See my former post:
BUT: There was never any official confirmation of my acceptance.
@Wolfsrudel is correct, Consul snapshots are not encrypted in either OSS or enterprise.
You can encrypt snapshots when storing them in your backup system. The Consul snapshot agent available in Consul Enterprise can be configured to instruct AWS S3 to encrypt data. That encryption happens entirely within S3, and is not performed by the snapshot agent (see: AWS S3 - Protecting data using server-side encryption).
