This update is for HYPER Core G4, HYPER Edge G2, HYPER Echo G1 and HYPER Echo G2.

Upgrading to this release will not require a reboot if the system is running on 5.3.x version branch. Reboot is required when upgrading from 5.2.1 and older versions.

Introduction

This update finishes a series of major Replication and Granular File Recovery improvements, and adds multiple usability improvements.

New features

In this release we have improved the user experience for scenarios where SynetoOS doesn’t have connectivity to Syneto Cloud endpoints on boot. Earlier, SynetoOS had a strong dependency on the connectivity to cloud endpoints for monitoring and alerting. However, for appliances that are deployed in isolated environments this could lead to a blocked UI.

Starting with SynetoOS 5.3.4 the UI will not be blocked if the appliance doesn’t have connectivity to the Syneto Cloud endpoints. This is a major user experience improvement for all Syneto products that operate in isolated environments, or environments with unstable internet connectivity.

Resolved issues

Replication

• Improvements to replication reliability in edge case scenarios.
   
• Improved the error message clarity for scenarios where deleting a replica fails if it has active file recovery mounts.

Granular File Recovery 

• Fixed the Encoding Issues caused by the 'ñ' Character in the Recovery Files.
   
• Fixed an issue that caused a recovered .zip file to become empty after a SynetoOS update.
   
• Fixed an issue causing a False positive when creating an ISO image fails because there is not enough space on the appliance. A concise error message is now displayed if there is not enough space.
   
• Improved clean up procedures to ensure no File recovery tasks are visible in the UI after clean up.

Web UI

• Improved the user experience for a scenario when SynetoOS does not have connection to the Syneto Cloud on boot. As a result the UI is not blocked and users can continue manage their Syneto infrastructure even if the appliances are not connected to the Syneto Cloud.
   
• Improved subtask messages by presenting task durations in a more user-friendly format (hours and minutes instead of seconds).
   
• Fixed the 'Create a virtual machine' button on the Dashboard page.
   
• Fixed an issue that could cause the Replication Targets page and the Protect tab/modal not to load if one of the targets is powered off.

Known issues

• Uploading a file to Image Repository can get stuck if there is no space on the storage pool.
   
• In some scenarios user may not be able to remove a Granular File Recovery ISO mount from the UI.
   
• In some scenarios users can observe two replication subtasks running at the same time.
   
• Replication Target is not be visible in the UI on the primary system if the replication target system does not allow SSH access.
