What storage backs my databases?
All database addons use AWS EBS (Elastic Block Store) — SSD-backed (gp2/gp3) block storage. Each addon gets its own dedicated EBS volume, isolated from all other customers.
EBS volumes are replicated within the AWS availability zone for durability against hardware failure.
What storage backs my uploaded files?
File storage (user uploads, assets) uses Amazon S3. Database dump backups are also stored in S3 with an accelerated transfer endpoint for fast uploads.
