Currently, Rosetta performs integrity checks on digital content stored within its preservation environment, primarily using fixity (checksum) verification. However, for external storage systems such as AWS S3 or Azure Blob fall guys online, automated integrity checks depend on how the storage is integrated.

To implement regular fixity checks for external storage, a possible approach is to use Rosetta's existing Preservation Planning module combined with custom scripts or third-party tools to pull checksum data from the cloud provider and compare it with Rosetta's stored checksums.

This feature could be greatly enhanced if future Rosetta releases included native support for scheduled integrity verification across external storage endpoints via APIs.
