User's Manual

About restore
When automatic or user-requested retrieval of backup data is initiated, user data and option
settings are set to values contained in the backup file. The user-requested retrieval of backup
data occurs only if the OPSTAT parameter setting allows the user to change those values.
Therefore, any restrictions set using OPSTAT are given priority and implemented.
The backup file value is not retrieved, and the current setting remains valid:
• When a value in the backup file has changed and
• That value corresponds to an application that OPSTAT indicates should not be
changed.
This method prevents a user from bypassing the administration of OPSTAT and changing
options settings in the backup file.
Note:
If you administered the APPSTAT parameter to suppress changes to one or more
applications, the phone backs up and restores data as usual, but ignores data for
“suppressed” applications. This method prevents a user from bypassing your APPSTAT
restrictions by editing the backup file. For information about APPSTAT, see
Setting the
Application Status flag (APPSTAT).
During backup file restoration, do not perform any user activity until the phone displays a
Retrieval successful or Retrieval Failed .
Important considerations during data retrieval are as follows:
• When you create a backup file instead of editing an existing one, ensure to create the file
with UTF-16 LE (little endian) characters, with Byte Order Mark (BOM) for LE of
0xFFFE.
• Backup saves data values using the generic format name=value. For specific formats,
see
Backup file formats on page 76.
• All identifiers, for example, names, are interpreted in a case-insensitive manner, except
parameter values, Contact names, and numbers.
• Spaces preceding, within, or following a name are treated as part of the name.
• <CR> and <LF> (UTF-16 characters 0x000D and 0x000A, respectively) are interpreted
as line termination characters.
• Blank lines are ignored.
• When an identifier is not recognized or is invalid, the entire line is ignored. Similarly, if an
identifier is valid but the data itself is invalid or incomplete, the line is ignored.
