Backup/Restore in Eon Mode on AWS S3
What's the current state of backup/recovery on EON with AWS S3? What happens with Vertica EON if AWS S3 gets slow or is even unavailable? Can the primary cluster survive? At least in read-only mode?

EON mode supports full backup/restore with s3 as well as object level restore from full backup on s3.
Even read-only will still need to read from s3 if files are not in depot. So if S3 is not available, there is nothing very interesting vertica could do.
My experience (not from AWS, but with S3-like storage) is quite positive, S3 protocol is very resilient, so queries are not failing immediately. Instead they can survive relatively long hiccup and finally finish successfully.
