- Multiple enhancements to support authorization, identify management and secure transport for Direct-to-Cloud mode
- Changed core hash algorithm from SHA-256 to BLAKE3 for enhanced performance
- Added config option to specify default Volume Shadow copy provider for backups
- Backup server and Cloud server URLs are now logged during backups for troubleshooting
- Backup progress per volume is logged during backups for troubleshooting
- Hibernate and suspend idle timeout is suppressed while backups are running
- Volume Identity Tracking prevents duplication of data if physical uuid changes

Summary of Direct-to-Cloud Support
Agent 2.26 in conjunction with Replibit release 10.4.0 now provides the option to perform backups directly to Axcient-hosted cloud vaults, bypassing the requirement for a local BDR appliance.
Agent changes include support for a special install mode, based on token information presented in the agent installer filename identifying the Cloud vault URL and customer identity, which triggers the D2C install mode.
Additional enhancements provide support for direct vault backup workflow, customer identification, authorization, and security for transport connections, and performance improvements to optimize and harden backup communications over the Internet.

Summary of Performance Enhancements
The core hashing algorithm for block change detection has been changed from SHA-256 to Blake3. This provides a significant reduction in CPU usage for hashing operations.
End-to-end communication workflows have been significantly hardened and optimized to better handle connection interruptions, packet loss, and intermittent availability of remote protected systems. This will help ensure the reliability of backups.
Cloudserver now maintains a separate copy of the hash table for all data written to the vault. The agent downloads the vault copy of the hash table before beginning a new full backup scan, which prevents sending any redundant data over the WAN in the event of subsequent full backup scans.
Auto Update Best Practices
We recommend that Enable Auto Update is enabled on the Settings -> Update Manager page on each of your Replibit devices.
We also recommend that you enable Auto-Enable Remote Assist When Upgrading so that remote access will be available to our development team should something go wrong with your upgrade.
This will ensure that your Replibit devices are updated with the latest software enhancements in a timely fashion, and that the Replibit Support team will have a short window of time to access and repair any troublesome devices without requiring user intervention.
