S3 Storage
S3-compatible storage with transfer included
Store files, media, datasets and backups in buckets that work with the AWS CLI, rclone and every S3 SDK. Change one endpoint and your code keeps working, with simple per-GB pricing and data transfer included in every plan.
What you get
- Full S3 API
- Buckets, multipart uploads, presigned URLs, versioning, lifecycle rules, CORS and bucket policies.
- Transfer included
- Each plan includes monthly data transfer. Beyond that, egress is a flat $0.01 per GB, with no request fees.
- Object lock
- Write-once, read-many retention for compliance and backups, in governance or compliance mode.
- Five regions
- Choose where each bucket lives, and replicate buckets across regions with one setting.
- Access keys with scope
- Create keys limited to one bucket, one prefix, or read-only access.
- Public buckets and websites
- Serve images, downloads and static sites straight from a bucket, with your own domain.

Questions
Is there a minimum storage duration?
No. Objects are billed for the time they are stored, with no 30 or 90 day minimums and no deletion fees.
Can I migrate from Amazon S3?
Yes. Use Server & Storage Sync to copy buckets from AWS, then keep them in sync until you switch your endpoint.
Do you charge for API requests?
No. GET, PUT, LIST and other requests are not billed separately.
How does included transfer work?
Your plan includes a monthly allowance shared by S3 egress and Server & Storage Sync transfer. It resets on your billing date.
Works with the rest of SyncBlaze
Every plan includes all four services. Usage from each counts against the same plan limits, so you pay for one account, not four.
