Release Notes for Active Backup for Business

Compatibility and Installation

1. Active Backup for Business 3.0.0 and above requires DSM 7.2 or above.
2. The following models are not supported in Active Backup for Business 3.0.0 or above:

• DS214play
• DS216play
• DS415play
• DS416play
• DS418play

Important Note
