Back up to aws s3

hi how to take backup in aws s3
where is the location aws backup ?? in aws setup incremental backup ask aws 2 keys only no location of bucket ??
how to restore aws back up i see on during restore backup its password so which password ?? or how to set password

Password is in sites public_html directory, in domain.tld file. But it seams that incremental restore is not working wit latest cyberpanel version- 2.1.2?

Just checked now, with cyberpanel 2.1.1 restore is working fine. Please check this.
