Disk space

This requirement varies based on the number of backed-up Active Directory and Azure Active Directory objects, the size of your Exchange (on-premises and online) and Google Workspace mailboxes, SharePoint Online and OneDrive for Business sites, and Google Workspace user drives, and the retention period that you set for your backups.

Active Directory and Azure Active Directory backups: 50GB (Minimum).

Exchange, Microsoft 365, and Google Workspace backup: RecoveryManager Plus typically compresses backups to a third of their original size. If the total size of the mailboxes, SharePoint Online, and OneDrive for Business sites, and Google Workspace user drives is 1TB, make sure that you have 1TB of free disk space to store the full backup and all subsequent incremental backups.

Note: Make sure that you have downloaded the 64-bit version of RecoveryManager Plus if you wish to backup your Exchange and Microsoft 365 environments.


Before you configure an Exchange environment for backup with RecoveryManager Plus, make sure that you satisfy the prerequisites listed below.

  • If you plan to install the product in a system running Windows 7 SP1 or Windows Server 2008, ensure you have Microsoft .NET version 4 and PowerShell version 2 installed in the system.
    • To check if Microsoft .NET Framework is installed, open Command Prompt from Run. Enter the following command reg query

      "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full" /v version

      Check the displayed version. If the version is below 4 or if it’s not installed, install Microsoft .NET Framework 4 from here.

    • To check if PowerShell is installed, type PowerShell from Run. If PowerShell is installed, check for its version number by running the command $PSVersionTable.
