Synchronisation

While working online, or within range of an offline server, records will be continuously synchronised. If working offline and without a standalone server, records will be stored on the local device until the next opportunity to synchronise.

Warning

Note that the Fieldmark App must be open for synchronisation to work. If you exit the App, synchronisation will be paused and restart when you return to the App.

Configuring Synchronisation

When you activate a notebook, record sync starts automatically. In Notebook Settings, use Sync mode to choose how record data moves between your device and the server:

Mode	Behaviour
Sync off (local device only)	Records stay on this device; nothing is sent to or received from the server.
Upload only	Your new and updated records upload to the server. Existing records from other devices are not downloaded.
Upload and download	Full two-way sync (default for smaller notebooks when online).

When you activate a notebook while online, the app may set Upload only automatically for notebooks with very large numbers of records, to save storage and mobile data. If the record count cannot be fetched (offline or error), Upload and download is used instead.

On the record list, a banner may suggest switching to Upload only when a large notebook is still using two-way sync.

Attachments from Other Users

Users can choose whether or not to synchronise files and attachments created by other users.

If enabled, the Fieldmark will automatically download and show images and attachments created on other devices. As this may be resource intensive and affect your mobile data plan, this setting can be disabled to minimise network usage. Attachments are always uploaded to the server regardless of this setting. This option requires Upload and download sync mode.

By default, notebooks are set to not download files and attachments created by other users. To activate, go to the Notebook Settings and turn Get attachments from other devices to On.

Verifying synchronisation

While online, or connected to the offline server, the App will continuously synchronise new and updated records on the device and the server. When on the project page, you will need to tap or click Refresh to reset the Record List and show recently synced records.

Note

Large datasets with numerous images may take several minutes to fully synchronise (particularly if teams have been offline for several days), but the majority of records and edits will appear instantaneously.

An icon in the App header will provide a notification if you are offline or sync has been disrupted.

To verify your records have synced, check them on a different computer.

Warning

Unsynchronized data will be lost if the App is uninstalled from a device or the browser cache is wiped.
