A3 Release Notes 7.2 build 9294

Alike v7.2.0 build 9294

Released: 10/23/2023

This is a major release. It improves all restore performance paths by 200%-500%, dramatically shrinking critical restore windows. This release also refreshes the Alike UI with look-and-feel enhancements.

Improvements

Accelerates core data engine components for restore throughput by leveraging new, pure shared-memory design
Introduces new "last mile" codepaths tailored to Xen performance needs, achieving full VM image restores that complete many times faster than any previous release
Look and Feel enhancements to Alike WebUI menus, navigation, and responsiveness improve overall Alike user-experience
Initial non-CBT Xen replication performance is addressed and improved
Also dramatically improves file-level restore performance, VHD/X individual disk restore, Hyper-V restore, and "instaboot" instant restore performance

Bug Fixes

Makes CBT replication the default choice for new replication jobs, rather than the slower non-CBT pathway
Resolves spurious "VM_Metrics" error during ABD deployment
Eliminates high CPU usage during restore functions
Inaccuracies in UI dashboard network and CPU utilization are addressed
Resolves issue where a instabooted VM disk could be erroneously deleted on A3 reboot due to cleanup race conditions
Corrects regression introduced in build 9167 where restores from Disk and Memory backup reboot during restore process, losing memory state

Known Issues

Users upgrading from A2/v6 may experience browser session issues during initial setup that require login/logout to resolve
Dashboard reports Docker container CPU and NIC utilization only, and cannot display all sources of network activity
