When to use

When you you have done some tracking and / or done some kind of data update, you are ready to export your tracks/notes to a Backup file.

Export extent

An export processes the App database on your device, and comprises:

• a) rows in state Recorded (new)
• b) previously exported rows
• c) rows in state Exported edited since last export
• d) crewmembers and boarding
• e) previousluy exported events
• f) these items:
  • the Mailcomposer Template
  • Tzone Templates setup by the Tzones page
  • items in the GeoRegions picker scroll list
• g) photos
• h) voices
• i) all options in the Settings Mainpage

The designation row is synonym with tracks and notes.

The f) and i) items are stored in a table named 'attitude' in the App database.

First export example

Imagine three tracks (titled 'T1', 'T2' and 'T3') have been created.

Tapping   Export   the first time will then open:

This page has no Options menu.

Tapping   Tap here to create a Backup file   opens:

When confirmed, export is done, ending up in a receipt:

Second export example

Now imagine this transaction sequence:

• track 'T4' is created
• track 'T3' (from above) is edited
• track 'T2' (from above) is deleted
• track 'T5' is created

Tapping   Export   a second time now opens:

Tapping   Tap here to create a Backup file   and confirming again, export is repeated and ends up with this receipt:

Third export example

Finally imagine a transaction sequence like:

• track 'T4' is deleted
• three crewmembers are created - like the example in Crew+Boardings
• one of these board all remaining tracks (T1, T3 and T5)
• another only boards one track (T5)
• the third doesn't board at all
• weather conditions are added to the first plot event for track T3
• two photos are added to track T1
• three voices are added to track T5

Tapping   Export   this time opens:

Tapping   Tap here to create a Backup file   and confirming again, export ends up with the receipt:

If no more transactions found place hereafter, tapping   Export   opens:

It's assumed, that the previous Backup file is preserved and still exists! Otherwise, do a new Export.

Export from a secondary device

A device is set secondary by setting Settings mainpage: Device is primary Switch OFF. This can only be done on a 'clean' device (meaning nothing needs to be updated).

But exporting is reserved the primary device - so tapping   Exort   on a secondary device is rejected:
