All data is restored through the public API of each cloud app. As a result, the restore process in itself is limited by the available API calls of each integration.
Unfortunately this means that we are not able to restore all data types (e.g. it is not possible to restore an entire Asana workspace) and that some restores have limitations (e.g. a restored item will not have its original files).
The restore capabilities are different for each integration and are documented on the Help Center.
Tip: We strongly recommend reviewing the restore capabilities for your SaaS apps so that you understand what sort of data can be restored with Pro Backup.
