  • Adds support for replication from / to VMware Hosts running vSphere version 7.0
  • Adds a new CLI tool for exporting VHDs or VMDKs directly from backup data without having to restore the Virtual Machine first.  This is available as a standalone tool within the Altaro VM Backup Install location.


  • Optimizes calls to vSphere and vCenter servers to ensure that a single session is used for all calls within an operation. This leads to improved performance when connecting to the vSphere API.

  • Fixes an issue where old backup version retention operations were not running concurrently per Customer and they were being queued sequentially
  • Fixes an issue where a restore operation to VMware vSphere 7.0 could fail
  • Fixes an issue where the delete all backup versions feature would fail and cause subsequent operations to fail
  • Fixes an issue that in very rare scenarios could cause a system error during CDP backups. (Hyper-V only).
