How do I add my server as a source/destination?

Everything you see in the Finder, you can select as a base in SyncTime.

If the server you want to select isn’t visible in the Finder, you can mount it by activating the Finder (e.g. by clicking the icon in the Dock), then selecting the menu Go > Connect to Server (or press Command-K). You’ll then be asked to enter the server address.

After you click Connect, you’ll be asked to enter the login credentials to the server.

If the option “Connect volumes automatically” in the Advanced tab of the sync settings is enabled and you would like the server credentials to be used automatically in the future, enable the option “Remember this password in my keychain”. macOS will then store the entered credentials. (The credentials are not accessible by SyncTime or other apps: when SyncTime starts a sync, it issues a mount request to macOS which then connects to the server.)

After you click Connect again, the volume will be mounted and visible in the Finder sidebar or on the Desktop. You can now select it in SyncTime.

Should the server address or login credentials change, the sync will fail with a Base unavailable error. To connect to the server again, mount it by following the steps above and select it as the new source or destination in the General tab of the sync settings.
