On linux, I do xfsdump's and rotate several full backups.  I
also leave the drives unmounted when not in use.  Ransomware
is only dangerous where they can find a drive letter.

I am trying to get a few of my Windows clients to back up to
a Linux ftp server (no drive letters).

Must have several rotations of data though.  I do not like incremental
backups, especially when I have all night to run a backup.

And single Windows workstations to back up to an ext4 drive with four
revolving partitions, so that only one drive letter is exposed at
a time.  Ext4 to screw with ransomware minds if they ever figure
out how to attack hidden drives in Windows.
