A further thought occurs, you could have backups done from the Primary to the Backup done over RSync which allows for removing files and the backup jobs from the Backup to the Primary would be ones that don’t edit but simply adds files to the Primary.

If the attorney uses the secondary NAS as a local primary, then there is inherently some risk that work will be lost. The attorney might occasionally start with an outdated file, and also his changes might not always reach the primary. You can reduce the odds if you know the normal work habits, but I don't think you can eliminate the risk unless you have a true 2-way sync.

BTW, If the bidirectional rsync jobs are using the same pair of shares, you would need to be extremely careful on the timing. You can't allow both backups to be running simultaneously, and there is no facility to guarantee this. Also, if the primary backup runs first it would delete any files the attorney added to the corresponding secondary share. It's an interesting notion, but it seems pretty fragile.
