C2C Agent creates a new full backup instead of incremental

Symptoms

While using the C2C Agent, you notice that one Backup took a lot of time to complete. When checking list of recovery points in Backup Console, you notice a slice is the same size as Full Backup taken originally or close to it.

Symptoms

You have registered an account and specified your backup storage (Partner-owned backup storage). You have registered a machine in that account and run a backup to the specified storage. Later, you have changed the storage in the account settings and removed the old storage.

All backups running to this new storage fail. In PCS logs you will see errors like:

Symptoms

  2. Backup, replication or another operation with a destination network share fails with:
