Time Machine: any way to know overall status of backups?

[seanm]

One thing I miss about macOS Server was that it had a UI to show the status of client machines that are backing up to the server, as in the screenshot below. It would also email if a machine did not backup in over a week.

It's nice to check in just one place to see if a client machine has failed to backup recently, instead of having to check every client. Is there a way (command line is fine), to get a similar list with FreeNAS? Is there a way to get FreeNAS to send an alert email if there's been no backup after x days?

Well, 'ls -l' in the dataset gives some info, as the modification date seems to match the latest backup date:

drwxrwxr-x+ 3 timemachine nogroup uarch 10 Apr 29 18:05 mac1.sparsebundle/
drwxrwxr-x+ 3 timemachine nogroup uarch 10 Apr 29 17:36 mac2.sparsebundle/
drwxrwxr-x+ 3 timemachine nogroup uarch 10 Apr 29 17:59 mac3.sparsebundle/
drwxrwxr-x+ 3 timemachine nogroup uarch 10 Apr 26 21:35 mac4.sparsebundle/

Indeed one of my Macs has not backed up recently...
