Macrium Image Guardian
Macrium Image Guardian Overview
Macrium Image Guardian protects your backup files from unauthorised modification.
MIG grants write access to existing backups file for Macrium Reflect 7.1, any image tools created by us, and optionally, MS RoboCopy. All other process attempting to update existing backup files will be denied access.
MIG protects local NTFS volumes and allows Macrium Reflect 7.1 and later to use the protected volume as a shared network resource.
Macrium Image Guardian protection architecture
Macrium Image Guardian protecting backups in a networked environment
In the above illustration, the PC sharing the backup repository (Shared Volume) has a full install of Macrium Reflect, including MIG. A local drive is shared over the network and MIG has been enabled on that drive in the Macrium Reflect user interface.
The other PC’s on the network can backup to this shared drive and do not require MIG to be installed. Backup file write access is automatically granted to Macrium Reflect 7.1, and later, write access for earlier versions of Macrium Reflect and other processes will fail.
The PC hosting the share with MIG installed can be used as a standalone Macrium Reflect installation. The protected drive will prevent unauthorised access to backup files on that drive if the local PC creates backups to the protected volume.
Macrium Reflect Free Edition
Now licensed for commercial as well as personal use.
We've relaxed the licensing for the Free Edition and it is now permitted to install and use this popular product in a commercial environment. Please note that this is still an unsupported product and, as always, we encourage upgrading for full functionality and support. Please see Upgrade from Macrium Reflect v7 Free Edition for more information on the benefits of upgrading.
Windows 10 Task Scheduler compatibility
The Free Edition now uses Windows Tasks Scheduler 2.0 API to overcome the problems with Windows 10 and the previous TS 1.0 API.
Instant virtualisation of Macrium Images is now included in the Free Edition installer.
New viBoot VHDX provider
When creating a new virtual machine Macrium viBoot will now create a Microsoft Virtual Hard Disk (.VHDX) file that's re-directed to an existing Macrium Image file (.MRIMG) and a differencing .VHDX that contains changes generated by the running Virtual Machine. Previously, a Macrium Image file was used to create a virtual SCSI disk which was then mounted in a Virtual Machine. The latest version is a huge improvement and offers greater persistence and performance. It also allows us to offer additional functionality in the future, such as compatibility with other virtualisation environments including VMWare and VirtualBox.
These new .VHDX files are stored in the designated Macrium viBoot Repository (default "C:\ProgramData\Macrium\viBoot" but configurable from within Macrium viBoot) and remain open until the Macrium viBoot virtual machine is deleted.
