Hello Thomas,
Each shop, for example a restaurant has its own local database on the computer the Point Of Sale software is running on.
The shops has ADSL connection with 1MBit upload speed and the database is around 50 MB and growing every day.
Uploading such file to our server with this bandwidth disturbs other Internet activities and at night they turn of the system.

So im trying to figure out an optimal backup solution.

Thanks,
