FTP File Server Backup Operation
Issue 1 July 2006 39
Backup Using the IP Telephone File Server Application as a File
Server
This operation provides periodic back up of FTP data to a primary and/or secondary server
running the file server application software. The data can be backed up every month/day/hour
or minute, the latter used normally for testing.
The FTP data backup operation acts like the TFTP firmware distribution, but in reverse. The
backup process works by the IP Telephone File Server Application building a list of the files in its
FTPdata subdirectory and issuing a request to the file server to GET these files. The file server
then issues multiple HTTPS “GET requests” back to the client to collect the backup list and all
the files the list contains. Only new or newer files are downloaded and stored in the file server
BackUp directory.
Automatic FTP data recovery is provided to the end user. When the telephone makes a request
to the FTP server and that server is not there for some reason, the local IP Telephone File
Server Application server will make a request to its designated Primary, then Secondary file
server to see if the file is available there. If found, the file is downloaded and stored locally
before being served to the local customer. This mode of operation can also help to deliver
personal phone data to users who roam in a corporate network and log in elsewhere, provided a
Uniform dial plan is used.
To use the backup feature, you must assign a number of configuration items:
1. Choose the mode for each given IP Telephone File Server Application server (client or file
server).
2. Enable the FTP Backup option in the INI setting.
3. Assign a primary and optional secondary file server address in each IP Telephone File
Server Application client.
4. Select the frequency of update. The default is hourly.
To check the backup operation, place a file in the FTPdata subdirectory and check that it is
received and stored in the Backup directory of the designated file server.
Backup Using Automatic Archive
If the Archive flag is set in the INI file settings section, the IP Telephone File Server Application
automatically backs up the data in the FTPdata directory. The archive works on a rolling seven
day basis naming the files Sun_FTParchive.zip, Mon_FTParchive.zip, and so on.
Archiving is typically done every hour. A copy of the latest archive is placed in the Backup
directory to allow it to be copied automatically to an IP Telephone File Server Application file
server.
