The DVM repository is full therefore transfers, rollups or replication is not possible. Errors found in AppRecovery logs:

Adjust your retention policy or delete the old recovery point chains to free up space, or add a new storage location to the existing repository
The repository is out of space.
There are a number of ways to resolve repository full issue.
Note: repository space can also be taken by machines in the Recovery Points Only section. This type of data is absolutely static, not affected by rollups and cannot be replicated to another Core. Still, that data can be deleted from repository using Delete All or Delete Range actions, if necessary
