Synchronization and backup

» You can find this setting in the Application settings. «

You usually do not have to change anything in this section of the settings. Any changes should be done only upon consulting the technical support instructions.

Unique installation code

An identification number used to identify all records in the relevant cash register database (unique cash register identifier).

Synchronization with Dotypos Cloud

Click to enable or disable the cash register connection to Dotypos Cloud and data synchronization. This option contains a unique cloud identifier (web storage where the cash register saves its data).


If you deactivate this option, the actual data will not be available in Dotypos Cloud and will not be backed up to the web storage. In case of a cash register outage, you can lose both. So this option should always be on.


Automatic backup

Enable automatic backup

Enables or disables the creation of automatic internal backups. We recommend keeping the option enabled. You can retrieve your data from internal backups when needed. When necessary, technical support can retrieve your data.


Data backups are saved into the folder DotykackaBackup and work as follows:

Data for the final month are retained in backups more than one year old. All other data is automatically deleted.

Data for the final day of the week is always retained in the most recent month.

The last backup for each day is always retained for the most recent week.

All four backups are retained for the most recent day.

Prefer external storage (SD card)

If a SD card is inserted in the device and this option is enabled, the backups will be automatically stored to this SD card.

Perform manual backup

Clicking here creates a new local backup.

Retention period

This setting defines the time period Dotypos keeps local data in cash registers. By default the data from the current and preceding month are kept. You can also choose your own interval or keep all data in the cash register. Older data are removed from the cash register always after the close of a shift, so it is important to close shifts regularly. Before deleting local data, Dotypos checks for the presence of identical data in Dotypos Cloud. So any data not yet synchronized with Dotypos Cloud cannot be deleted for any reason.

If you need to display an already removed receipt in the cash register, find it in the History. Once you open it in the history, the receipt will be automatically downloaded into the cash register.

Sample settings:
If you set a one-month time interval and it is August now, the data will be available in the cash register from 1st July to 31st August. On 1st September the data for July will be automatically deleted. The same applies to other intervals: 1 day = data for today and the entire preceding day.



The data storage period determines the size of the database in the cash register. Large data volumes in the database can cause the cash register to operate slower, especially if the transaction amount is high. So we recommend keeping the default settings. Older data are always available in Dotypos Cloud.
