DPX 4.16 Release Notes

New Features in DPX 4.16​

This release provides extended tape library management capabilities in the web UI, adds Proxmox backup and restore support, and improves disaster recovery visibility and flexibility.

Proxmox Backup and Restore​

A new job type has been added with support for backup and restore of Proxmox virtual machines. The implementation covers full and incremental backups to vStor, full VM restore, backup job scheduling, and Proxmox node management. Restore from Block Archive

Block archive restore is now available in the web UI, providing full feature parity with the previous implementation and a more modern workflow experience.

Restore from VMware Archive​

VMware archive restore has been migrated to the web UI and is now integrated with the Multi-VM restore workflow. Administrators can restore multiple VMware VMs from an archive in a single UI flow without defining separate job definitions.

VMware vTPM Support​

Backup and restore of VMware virtual machines encrypted with vTPM modules is now supported, extending compatibility with secured VM configurations.

Extended Tape Library Support​

Tape library management in the web UI has been significantly expanded:

  • Tape registration – Register new tapes within DPX for use in backup jobs.

  • Import and export – Move tapes in and out of designated export slots in the library, enabling administrators to shelve full tapes or introduce new ones.

  • Automatic library scan – Configure automatic scans so that DPX stays up to date with library contents.

  • Improved library view – The tape library view more accurately reflects the physical state of the library, with data refreshing more frequently without requiring the user to navigate away and back.

Alternate Secondary Volume in Multi-VM Restore​

Administrators can now override the vStor volume used during Multi-VM restore, allowing recovery from any volume that contains the required data. This is particularly useful in disaster recovery scenarios where the original volume information is no longer available in DPX, like restoring data from any type of archive.

Job Instance Tracking for RRP​

The RRP process is a part of the VMware restore job that physically migrates the underlying data to a new location (moving from instant to full restore). In large environments, this process can take multiple hours. Now it is possible to see the progress of this process and track it just as any other type of job.

Notable Improvements in DPX 4.16​

  • Latest run info in Job Manager – The Job Manager view now displays the time of the last execution for each job definition.

  • Spacing adjustments – Layout density has been improved across multiple areas of the DPX and vStor interfaces, allowing more data to be visible on screen at once.

  • Improved vStor volume cleanup for removed VMs – Storage space is now correctly reclaimed after backup expiry when a VM has been removed from the environment and from backup jobs. Previously, space was not always released in this scenario.

New Features in vStor 4.16​

This release delivers end-to-end audit log support, expanded and standardized filtering across the product, and a range of usability and consistency improvements.

Audit Logs​

Full audit log support is now available in both the web UI and backend. The feature includes event collection for REST and system actions, configurable retention settings, filtering, pagination, and CSV export.

Expanded Filtering​

All remaining legacy filters have been reworked to match the new standard used across the product. Date filter and calendar behavior have been improved for a more consistent experience.

Volume Migration​

Volume move relocates a volume from one storage pool to another. What was called volume move is now consistently labeled as volume migration across the UI. Migration tasks appear in the global task list, not only in volume details, with ETA and throughput information, suspend and resume support, and clearer status when a migration is suspended. Tooltips explain when actions such as volume delete are blocked during a migration.

Clone Indication in Snapshot List​

Snapshot list entries now clearly indicate when a snapshot has associated clones, with direct navigation to the clones and mounts list for that snapshot. This improves situational awareness when managing snapshot chains and dependent restore workflows.

RAW File Restore to SMB with Relative Paths​

Building on the RAW file restore introduced in vStor 4.15, mounted images now support restoring files to SMB shares using relative paths, which are the default for SMB restore. Administrators can choose full or relative path mode, adjust common-prefix trimming depth, and preview the resulting output structure before starting a restore. The restore dialog has been aligned across ZIP download and SMB restore flows, with improved overwrite handling. This reduces the risk of excessively deep folder paths on Windows destinations when restoring nested file-server content.

Notable Improvements in vStor 4.16​

  • Replication and move workflow improvements – When creating replication or offload relationships, administrators are prompted to start data transfer immediately. Synchronization and Offload actions are available in the volume replication and offload tabs. The replication session view loads and responds faster.

  • Restore and mount usability – Restore-to-network-share dialogs include clearer option descriptions. Mounting snapshots from encrypted volumes shows explanatory UI guidance. Downloaded artifacts follow unified, validated naming rules.

  • Interface consistency – Unified auto-refresh controls, standardized table row height, improved toast notification coverage, collapsible sidebar admin section, enhanced pool deletion modal, dark mode input readability fixes, and clearer dashboard and pool naming.

Release Engineering​

Unified Update ISO​

DPX 4.16 introduces a single unified update artifact that replaces the previously separate update ISOs for DPX appliance, vStor appliance, physical DPX, physical vStor, virtualization proxy appliance, and backup appliance. Any DPX component – regardless of deployment form – can now be updated using the unified ISO and accompanying script.
