Exclude downloaded map data from backup

[billie80]

This is more of a feature request.

Is it possible to exclude downloaded map data from backup?

The reason behind this is:

1. The settings itself are in general are more important than map data.
2. It takes very long to back up the data.
3. It consumes a lot of space.
4. It is outdated very quick and if there is a need to restore the data it makes more sense to retrieve updated material.

It should be possible to exclude files/native it in the backup schemes.
