I'm sure we've discussed this before... What other backup systems have you used before besides Macrium and Easeus? For example, have you used Windows Backup? I don't know if it's any good, I haven't been using it.

What I'm using:

MacOS: Using the built in Time Machine backup, backing up to an external SSD and also to a shared volume on our home NAS. This runs continuously in the background and keeps things pretty well up-to-date all the time without me having to think about it.

Windows: I'm using the Beyond Compare diffing tool to perform occasional syncs of my data and project folders to an External SSD. I don't use the Windows machine very much these days, so I'm not running any serious backup utilities. I just make sure to have extra copies of those files.

Both systems: I use the Beyond Compare diffing tool to keep my data and project folders up-to-date between the two systems.
