    Hi there

    run the backup FROM the Linux server (obviously with Internet disconnected) and AFTER checking Windows box that there's no malware on it.

    From linux you'll need something like RSYNC or GRSYNC (graphical / GUI version of RSYNC) which is great for backing up DATA.

    For the (Windows) OS use something from he Linux box like CLONEZILLA which will image the OS (Windows HDD).

    It depends on how many systems you need to backup.
    If it's only 1 or 2 client machines then a stand alone backup on each client using macrium is fine -- but if you need an automated process you'll essentially have to use Linux. I'm not sure how complex job scheduling can be done in Windows --hopefully people better qualified than me could answer this question -- however it's relatively easy on Linux if the server can access your Windows drives.

    Simply use the Crontab to schedule your jobs and ensure the client (Windows) machines are available to the server.

    You will need to install SAMBA on the Linux machine though.

    Also you can actually have the Linux machine as a VM --it can still backup HDD's from the Host !!!.

    This makes sense, more elaboration! I love it. OK, this sounds like a fine process - however, how would we accomplish it without having to manually check the Windows box for malware and file integrity? There is no automatic fail safe that doesn't require user intervention?

    I tried to implement that with my WSH script on my Windows box, without Linux. Trying to be as resourceful as I can

    Yes, virtualization is an option that I always consider, especially with a lot of my work invested in the field.

    I'm super invested into security, it's my specialty.

    This is what I'm thinking of doing.

    Backup my files to an external provider that offers unlimited backups, that is versioning. This would hopefully allow me to go back to non ransomeware-compromised files and restore them if necessary. It also serves in storing backups in a remote location (using the 3 2 1 backup strategy). I'm also considering using a combination of Folder Guard with FreeFileSync in order to do backups on an external portable USB drive. If Folder Guard works as advertised, then it would deter an attack on the backup files, plus I would have a portable backup of my data.

    Plug in external ocassionally. Run robocopy job to backup data using /mir switch. Disconnect external drive and keep offsite. Best practice, have 2 different external drives offsite.

    I was trying to see what might be a good way to protect oneself from ransomware. The reason that I started thinking about this is that my external backup disks are continuously connected to my PC. This would mean that a ransomware attack could infect those external disks as well as my internal disk.

    Unfortunately the discussion threads that I saw do not come up with anything definitive other than to have at least one backup offline. The most useful strategy that I read was in Idea for ransomware protection of network drives where the poster suggests the following steps.

    I wish I could develop a program to do all that automatically, on a schedule!
    All software methods of isolating external drives are flawed on basic principles. Anything you can do with software can also be done by malware, at least in theory. Techniques such as unmounting the drive reduce the risks but they cannot eliminate them. Security is always relative. At this moment some malware author somewhere may be working on a method of evading this protection. They will of course remain silent on the matter.
