Encrypted cold copies may sporadically fail.
Cold copy backups of non-encrypted data may occasionally fail when the encrypt option is selected for the cold copy job.
To resolve this issue, upgrade your appliance to version 10.1.
When exporting data to cold copy media, non-encrypted backups that are requested to be encrypted through the export (a processed called "transform") were not being properly noted, resulting in threaded archive processes being used where they shoudl not. In rare cases performance might suffer in these cases resulting in intermittent failures. This condition is now properly detected and threading will not be used on cold copies using transforms regardless of encryption status.
