I want to be able to know a backup has been completed.
For example I want to do a backup and then shut HA down or reboot it.
How?
- Maybe an extra parameter to the service call to say you want to wait until completion?
- A sensor state change
a) date/time of latest backup ?
b) backup in progress yes/no ?
Somehow the installation of any HA upgrade, which these days recommends a backup, waits for the backup to complete.
