    Windows backup application that supports EXT4?


    My question isn't specific to Windows 10, but this forum has a lot of traction so I figured I could ask here.

    I run an automated backup job every day to copy files from my main drive to a second drive in the same computer.
    I got hit recently by ransomware, which encrypted files on both disks. Thankfully, I had a backup on another drive that was recently disconnected so didn't lose important files.

    As a cheaper alternative to getting a NAS to run eg. rsync between Windows and the NASI was thinking of…
    • partitioning the second drive as EXT4
    • running a Windows backup application that can access EXT4 partitions natively, so that the partition would still be off-limit to Windows

    Is there such a thing?

    Thank you.

    Not a backup program but Paragon ExtFS for Windows will apparently read / write to an EXT2,3 or 4 filesystem.

    Write / read access to Linux files under Windows(R) - Paragon ExtFS for Windows(R)

    As it's a driver that mounts the disk / partition, I presume any Windows backup program would write to it.
    No guarantees as not tried it, there are a few free drivers however it seems to be a bit hit and miss as to if they actually work!

    Thanks for the link. I'll check if the driver can only be activated before and after running the backup application, although that still leaves a window opportunity for a virus to hit the files.

    Why not to backup to a cloud? No malware will be able to modify it without cracking your password first. Here is one from Windows Store:
