In the case of AD Zones, the data is all stored within AD itself so there are no files to backup.
It would be really, really helpful if Liongard would return the contents of the dns zone into the dns section rather than just a list of dns zones, as that does not assist in recovery of for checking if spurious dns entries have been made or changed.
I would expect the zone object to be expandable to see the contents of the zone file itself.
Bonus points if the data is exportable to a file that can then be restored, but it would also be good to have this as individual endpoints so a trigger could occur if the mx records were changed (as an example) or hypothetically speaking someone deletes the entire zone.
