Computer Help and Support

They seem to have a very good knowledge base on their website. This is from a two second glance at their website but the knowledge base is extensive if you have time to browse and read through a few tutorials.

Basic backup: https://knowledgebase.macrium.com/display/KNOW7/Creating+a+backup+image+of+your+computer%2C+drive+or+partitions

Restore to different hardware (doesn't get into entering a key#): https://knowledgebase.macrium.com/display/KNOW7/Re-deploying+Windows+to+new+hardware+using+Macrium+ReDeploy

I've made compressed backups (compressed just means it saves only used areas of the partition and ignores free space. Uncompressed or byte by byte copies everything including empty space so the backup is exactly the same size as the partitions it is copying.) and restored them to an empty older small HD with success. Todo backup also worked but i believe they no longer offer a free Home version but a more limited free version and Macrium makes a slightly smaller/tighter backup file anyway.
