18.1 Total Recall
Total Recall is a Psion Teklogix utility for backing up and restoring files and configurations. Its
primary use is to save a copy of data which would otherwise be lost during a cold reset of the
device to a permanent or removable storage medium. This allows the data to be restored when
necessary.
Previously, Total Recall was also used for purposes of cloning data from one device to another
similar device. This functionality has been deprecated.
Total Recall can be run either using the Mobile Devices SDK, using a Control Panel program, or
from the command line.
At this time, using the Mobile Devices SDK the only form of backup and restore that is available
is a complete backup of all files, databases, and the registry to the default folder. Selection of com-
ponents to back up is not available. Profiles can only be autorestored from the default folder.
18.2 Cold Resets And Clean Starts
A clean start should only be performed by Psion Teklogix personnel. This returns the registry to its
factory settings and removes all files from flash. For more details on reset and clean start proce-
dures and effects, see Section 1.5: “Resetting Psion Teklogix Computers”.
18.3 Backup Profile
A Total Recall backup profile is a collection of files and/or registry settings that can be manually
or automatically restored. A complete description of Total Recall for each Psion Teklogix com-
puter is included in the user manual for each computer. This section provides an overview of Total
Recall.
18.4 Profile Types
The are three types of Total Recall profile:
• For this device only — a backup that is manually restored by the operator.
• AutoRestore for this device only — a backup that automatically restores itself after a cold
reset or a clean start.
• AutoRestore for this and other devices (deprecated) — a backup that restores itself after a
cold reset or a clean start. This does not include the touchscreen calibration or the wireless
radio settings. This profile can be used to clone files and settings from one computer to
another.
18.5 Profile Content
A profile contains one or more of the following:
• Files
• Databases
• Registry settings
Files
This option allows all the files on the device (excluding system files) or only a selected list of files
to be included in the backup.
