## April 1, 2026
Arcserve Japan G.K. (Headquarters: Chiyoda-ku, Tokyo; hereinafter Arcserve Japan) will begin providing the latest version 1.6 of its on-premises 'Arcserve® Cyber Resilient Storage (CRS)' starting April 1, 2026. This immutable storage solution is specifically designed for ransomware protection.
The CRS series provides immutable storage focused on protecting backup data within the 'Arcserve® Unified Data Protection (UDP)' integrated backup/recovery solution. It is available in three types: on-premises, cloud, and appliance.
Arcserve CRS 1.6, the latest on-premises release, introduces critical new features for customers with stringent security requirements or those seeking improved operational efficiency.
By continuously enhancing the Arcserve CRS series, Arcserve Japan responds promptly to customer needs. Even in the event of a ransomware attack, the solution protects critical backup data, supporting early recovery and business continuity.
## [New Features in Arcserve CRS 1.6]
Arcserve CRS 1.6 adds three major improvements: 1) Support for Dark Sites, 2) Network Profile Management, and 3) SMART Disk Alerts. These enable coverage for a wide range of needs, from physical layer monitoring to operations in specialized network environments.
### 1) Support for Dark Sites (Closed Networks)
The update supports operations in 'Air Gap' (physical isolation) environments that are completely cut off from external networks due to strict security requirements. Three specific features have been added:
- **Offline Updates:** Software updates for Arcserve CRS can now be performed offline using USB media, DVDs, etc.
- **Local NTP Server Support:** Arcserve CRS requires time synchronization with an NTP server that supports NTS for its internal operations. Starting with version 1.6, local NTP servers are supported, maintaining data immutability, retention policies, and audit functions even when communication with external NTP servers is impossible.
- **Offline Export of Support Bundles:** Information such as logs (support bundles) can be exported offline to USB media. This allows the provision of support bundles to Arcserve Technical Support even if Arcserve CRS is not connected to the internet.
*Note: Remote support (Remote Access) from Arcserve Technical Support still requires an internet connection as before.
### 2) Network Profile Management
Profiles are available to simplify deployment and ensure consistent, high-security network behavior.
- **Dynamic Network Profile Switching:** Administrators can pre-define, assign, and switch network profiles without changing the data's immutable state.
- **Security Maintenance:** Tamper-proofing and auditable network configurations are maintained throughout the environment.
