OP-Z Automated Backup for macOS

Setup

  1. Store backup.sh somewhere and make it executable:

    $ vim ~/Music/OP-Z/Backups/Support/backup.sh

    (The file opz_backup.sh is only needed as a convenience shortut to manually run the backup)

  2. Store local.opzbackup.plist at ~/Library/LaunchAgents:

    $ vim ~/Library/LaunchAgents/local.opzbackup.plist

    Update the keys SOURCE, TARGET, Program, StandardOutPath and StandardErrorPath to match your desired locations.

  3. Open System Preferences → Privacy → Full Disk Access and add your sh binary to the list (/bin/sh) or if it is already there, enable the checkbox.

  4. Load the launch agent:

    $ launchctl load ~/Library/LaunchAgents/local.opzbackup.plist

Backups should now be automatically performed when connecting the OP-Z as a mounted disk (by connecting it over USB and pressing and holding the track button Ⓘ while turning the device on).
