 ______________ | Macrium Image Guardian protects your backup files from unauthorised modification. MIG only grants write access to Macrium Reflect v7.1 and any image tools created by us. All other process will be denied write access. MIG protects local NTFS volumes and allows Macrium Reflect v7.1 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 require MIG to be installed. Backup file write access is automatically granted to Macrium Reflect v7.1, and later, all other write access 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.
