Command Description

!NVBACKUP

=<category>

Supporting modems:

• All

Backs up items stored in non-volatile memory

This command creates a backup that is stored in the modem’s flash memory.

Parameters:

<category> (specify items to back up):

• 0 = Factory items (RF calibration data) — Used only at the factory (only

needs to be done once for the lifetime of the device)

• 1 = OEM items (PRI customizations) — Used only by the OEM when loading

a new PRI configuration (only needs to be done once for the lifetime of the

device)

• 2 = User items (customizations, including those made by Watcher or other

host applications) — This is the only backup option that should be employed

by users. Use this command before doing a firmware update. If the

modem’s file system is reinitialized for some reason during the update, the

customizations would then be automatically restored using from the backed-

up information.

The command returns:

• NV Items saved

• NV Items skipped

The ‘items skipped’ represent memory to which nothing has been written.
