Sandbox data copy and storage allocations
Key Takeaway
Match the sandbox type to the business need by what it copies, how much data and file storage it gets, and how often you can refresh it.
A sandbox is a copy of your Salesforce org in a separate, fully isolated environment. You use it for purposes such as testing and training, and nothing you do in it affects your production org. There are four sandbox types: Developer, Developer Pro, Partial Copy and Full. They differ in what they copy from your production org (metadata only, sample data or all data), how much data and file storage they get, and how often you can refresh them.
The four sandbox types
| Sandbox type | What it copies | Data storage | File storage | Refresh interval |
|---|---|---|---|---|
| Developer | Metadata only | 200 MB | 200 MB | 1 day |
| Developer Pro | Metadata only | 1 GB | 1 GB | 1 day |
| Partial Copy | Metadata plus sample data | 5 GB | Same as your production org | 5 days |
| Full | Metadata and all data | Same as your production org | Same as your production org | 29 days |
Developer and Developer Pro sandboxes copy metadata only, so they get your configuration but none of your production records. The 29-day refresh interval of a Full sandbox is the longest of any sandbox type.
