## Backup/Restore

The 9600 Series IP Telephones support the HTTP client to back up and restore the user-specific data indicated in Table 10. For backup, the telephone creates a file with all the user-specific data if a backup file location is specified in system parameter BRURI. The file is sent to the server by an HTTP PUT message, with appropriate success or failure confirmation.

For restore, the initiating process must supply only the backup file name. The file is requested from the server by an HTTP GET message. If successful, the file is returned to the initiating process, otherwise a failure message is returned.

Backup and restore operations construct the URI used in the HTTP message from the value of the BRURI parameter and from the file name as follows:

- If BRURI ends with /:ddd, where ddd is one to five ASCII numeric digits, the file name is inserted between the forward slash and the colon.
- If BRURI ends with / (a forward slash), the file name is appended.
- Otherwise, a forward slash is appended to the BRURI value, then the file name is appended to that.

HTTP authentication is supported for both backup and restore operations. The authentication credentials and realm are stored in re-programmable, non-volatile memory, which is not overwritten when new telephone software is downloaded. Both the authentication credentials and realm have a default value of null, set at manufacture or at any other time user-specific data is removed from the telephone.

The new value(s) replace the currently stored values:

- when HTTP authentication for backup or restore succeeds and
- if the userid, password or realm used differs from those currently stored in the telephone.

If HTTP authentication fails, the user is prompted to enter new credentials.

NOTE: Users can request a backup or restore using the Advanced Options Backup/Restore screen, as detailed in the user guide for their specific telephone model. or specific error messages relating to Backup/Restore, see the Avaya one-X Deskphone Edition for 9600 IP Telephones Installation and Maintenance Guide.
