What is ManageEngine RecoveryManager Plus?

RecoveryManager Plus keeps widening its backup coverage across the Microsoft identity estate.

RecoveryManager Plus is a backup-and-recovery tool for Active Directory and Microsoft 365, and it is the most feature-active of the ManageEngine set here. Recent builds add real backup coverage — AD sites and subnets, Entra ID local admin passwords, S3-compatible repositories, SIEM audit forwarding, and Entra ID BitLocker recovery keys — alongside CVE patches and RemCom agent hardening. Build 6322 is the quietest of the run: a single fix for restarts triggered by an outdated ExchangeOnlineManagement PowerShell module during Microsoft 365 enumeration.

What is skylight?

A frozen astronomical model quietly became the inner loop of its sibling's optimizer.

skylight returns sun and moon illuminance, azimuth and altitude for a given date, time and location, implemented as a near-verbatim transcription of a 1987 US Naval Observatory circular. The model formulation has not changed since the initial 2022 release and the author states so explicitly. Everything shipped since has been packaging, citation and speed: v1.3 moved the main routine from R to C++, and v1.4 removed a parameter check that was flooding the console with messages.

ManageEngine RecoveryManager Plus vs skylight: editorial side-by-side

M2.5

RecoveryManager Plus keeps widening its backup coverage across the Microsoft identity estate.

◆ Current state

RecoveryManager Plus is a backup-and-recovery tool for Active Directory and Microsoft 365, and it is the most feature-active of the ManageEngine set here. Recent builds add real backup coverage — AD sites and subnets, Entra ID local admin passwords, S3-compatible repositories, SIEM audit forwarding, and Entra ID BitLocker recovery keys — alongside CVE patches and RemCom agent hardening. Build 6322 is the quietest of the run: a single fix for restarts triggered by an outdated ExchangeOnlineManagement PowerShell module during Microsoft 365 enumeration.

◆ Where it's heading

The direction is coverage expansion: methodically extending what can be backed up and restored across on-prem AD and Entra ID, while broadening cloud storage targets and operational integrations. The dependence on Microsoft's own PowerShell modules is the cost of that coverage, and 6322 shows where it bites — a stale module on the customer's side takes the product down mid-enumeration. Feature builds and pure-fix builds alternate at roughly a two-month cadence, so a single-issue build reads as a gap between feature cycles rather than a slowdown.

◆ Prediction

Expect continued expansion of Entra ID and cloud-native backup coverage and more storage-target options, with security patches folded into each build; the next build carrying a Features section is due on the cadence this feed has held.

A frozen astronomical model quietly became the inner loop of its sibling's optimizer.

◆ Current state

skylight returns sun and moon illuminance, azimuth and altitude for a given date, time and location, implemented as a near-verbatim transcription of a 1987 US Naval Observatory circular. The model formulation has not changed since the initial 2022 release and the author states so explicitly. Everything shipped since has been packaging, citation and speed: v1.3 moved the main routine from R to C++, and v1.4 removed a parameter check that was flooding the console with messages.

◆ Where it's heading

This is a reference implementation of a published algorithm rather than a product accumulating features, and it is being maintained that way. The movement that does occur is driven from downstream: the C++ port was written for the inverse-modelling loop in the sibling skytrackr package, which calls skylight repeatedly during optimization. That reframes skylight from a standalone calculator into the compute kernel another package's fitting routine depends on.

◆ Prediction

With the model formulation deliberately fixed and the C++ path already in place, the next release is most likely another small maintenance fix. The entries give no indication of planned new capability.
