Backing up applications

1. Format a flash drive with a GPT (GUID) partition table and a FAT32 partition. These instructions vary by operating system, so see Formatting USB flash drives for more detailed help.
2. Insert the flash drive into the OnTakt server PC.
3. Open the daemon "System" page and scroll down to the "Backups" section.
4. Select the FAT32 partition you want to store the backup files on from the device dropdown. If your device is not listed, click the refresh button.
5. Click Save to set the backup partition, or Save & Run to also back up all applications immediately.
6. To back up a single application once the backup partition has been set, click the Back Up button under that application in the list at the top of the System page.

If automatic backups are enabled, the selected USB device must be plugged in when they run. It is not necessary to re-select the partition after disconnecting and reconnecting the device unless it is reformatted.

Troubleshooting

My USB device is not listed

Make sure it is formatted as GPT (GUID) and there is at least one FAT32 (not exFAT) partition on the device.

If it still doesn't show up, try a different USB flash drive.

Backup task failed with "can't find PARTUUID"

Reformat the USB flash drive with a GPT (GUID) partition table, not MBR.

Updating the OnTakt Daemon

1. Visit the services landing page by visiting the IP address of the OnTakt server, or by clicking Services from the user menu inside OnTakt or Inspection.
2. Switch to the System tab at the top.
3. Click the Update button under the current "Daemon version" display.
   
4. If the update fails to install, try again after restarting the entire server with the Restart button right below the Update button.
5. If the update still won't install, contact support.

Enabling offline updates for existing offline installations

OnTakt Daemon 1.0.3 with missing system components. Both services are running, but their status is not displayed.

OnTakt Daemon versions before 1.0.0 could not install system or service updates without an internet connection. Upgrading to the version 1.0.0 or later from a pre-1.0.0 version requires an internet connection to download additional software after installation. To upgrade an offline installation from a pre-1.0.0 version to a version that supports offline updates, follow the steps below:

1. Move the IPC to a network with internet access, including updating IP address settings if necessary. Note the old configuration to reapply later if anything needs to be changed.
2. Click the system update button to download and install the latest daemon version and other system updates.
3. When the system update completes, reboot the IPC with the system restart button.
4. When it comes back online, wait for it to download the rest of the components it needs. Until this completes, the service controls will say "Start" even if they're running, and service controls (including updates) won't work.
5. Install service updates by clicking the update button under each service. This could be done offline afterwards, but it's easier to do it while it's online anyway.
6. Put the IPC back on the machine network. Reapply any static IP settings that were removed in step 1.
