Since the Carlson Surveyor+ (and any other collector with Windows Mobile 5 and higher) uses internal flash memory for all the Software Applications you install and Data Storage instead of RAM memory as did the older collectors running WindowsCE such as the Carlson Explorer or Juniper AllegroCX, having a backup method is not as critical.
But backup methods are available as explained at:
Windows Mobile Field PCs
The entire system of a Microsoft Windows Mobile 5.0 or higher Field PC (Archer, Allegro MX) is stored in non-volatile flash memory. This means that performing a system backup is not as critical as it was with devices that used previous versions of the Microsoft Windows Mobile and Windows CE operating systems which stored the majority of the system in volatile RAM memory.
If you would like to perform a full system backup of the Field PC, a third-party program is required, such as one of the following:
Several options are available to automatically transfer (synchronize) data between a Data Collector and a desktop computer or server. A link to the website for each option is provided in the table below.
* Note: The file synchronization feature in Microsoft ActiveSync is being deprecated by direct access to database information (such as with a Microsoft Exchange Server database, which is not available in Windows CE 4.2 and older on the Carlson Explorer, Allegro CX and previous Allegro models)
