Which Amazon S3 storage class should I use with Storage Studio?
Short answer: Use S3 Standard for backups you restore often or Standard-IA for ones you rarely touch. Glacier is cheaper but slow to retrieve. Avoid S3 Express One Zone — it keeps a single copy and Storage Studio won't save it.
For backups, use S3 Standard if you'll restore often, or S3 Standard-IA for older backups you rarely touch. The Glacier classes are cheaper to keep but slower to get back, so save them for archives you're sure you won't need quickly.
Avoid S3 Express One Zone entirely: it costs more, keeps only a single copy in one location, and isn't suitable for backups. Storage Studio won't save an Express bucket. Check Amazon's current pricing page for costs — they vary by region.
