RE: Dataverse capacity limiting while copying
Hey!
There are 2 types of Copies
- Everything/Full Copy, means that all (Customizations, schema and data) will overwrite the target environment
- Minimal copy. This copy includes customizations + Schema (no data).
this is documented on Copy an environment - Power Platform | Microsoft Docs.
If you trigger a "full" copy from Production to Sandbox, it means that an image of the same size will overwrite the target, thus occupying the same as if it were a production. This will increase your storage consumption and will be deduced from your entitlement.
The alternative is to use a "Minimal" (Customizations+Schema). This type of copy overwrites the target environment without regular/customer records (accounts, cases, contacts, etc). but keep system records (Webresource, RibbonClientMetadata, etc). It might happen that even this minimal copy is bigger than the sandbox and the same will happen: if the copy will overwrite the target and therefore occupy more, deducing from your entitlement.
Please remember that in order to trigger a Copy/Restore,you need at least 1GB of available database capacity.
