I just wouldn't. I've had more issues with exFAT than anything else. The only real issue with FAT32 is the 4GB file limit. I've resorted to things like FTP or Syncthing to transfer files between different operating systems, particularly if I have files larger than 4GB. Backup software generally uses small file sizes, so that's something where FAT32 works for all systems.
