Warning: These interfaces are still experimental and are subject to
change.
backup-manager supports reporting its activity over dbus. Programs
wanting to be notified should listen to these messages of the
org.backupmanager.BackupManager interface :
* ProgressNotify (int32 percentage, string label)
* EventNotify (string event_name, string argument)
* LogMessageNotify (string level, string message)
Depending on who launched backup-manager (root or user), these messages
are sent from the following bus objects :
* /org/backupmanager/instance/SystemInstance of the system bus if
launched by root.
* /org/backupmanager/instance/UserInstance/${USERNAME} of the user
session bus if launched by a regular user.
If the dbus-send program is not in $PATH, or if the selected bus is
unreachable, backup-manager should operate as normal, just not
reporting its activity.
To test, just launch, in two different terminals for better
readability:
* as root :
# dbus-monitor --system \
"type='signal',interface='org.backupmanager.BackupManager'"
# backup-manager [...] # as usual
* or as a user :
$ dbus-monitor --session \
"type='signal',interface='org.backupmanager.BackupManager'"
$ backup-manager [...] # as usual
