Backing Up and Restoring
PSAX System Files
Overview of This Chapter
This chapter describes how to back up and restore PSAX system configura-
tion database files.
The following procedures are presented:
•
Backing up PSAX system, module, and connection configuration database
files by using the following methods:
~
Backing up database files using FTP (see “Backing Up System Database
Files” on page 10-2)
~
Backing up database files using XModem/YModem file transfer (see
“Backing Up Database Files Using XModem/YModem Transfer” on
page 10-7)
•
Restoring PSAX configuration and connection database files by using the
following methods:
~
Restoring database files using FTP (see “Restoring Database Files Using

Database Configuration Save and Restore Feature
The Database Configuration Save and Restore feature enables you to back up
and restore the PSAX system database files to, and from, a remote host com-
puter, such as a Unix or Windows-based workstation. The remote host com-
puter must be running as an FTP server. Files are backed up using FTP from
the CPU module system disk to a user-defined directory on a remote host
computer. When needed, you can restore the backed up files using FTP to the
CPU module. The restored files are placed in a temporary location on the
CPU module and are then checked for errors using a sanity checking proce-
dure. If no errors are found, the PSAX system moves the files from the tem-
porary location to the established current directory on the CPU module.
This setup includes creating a directory on the remote host computer where
the backup configuration files will be stored, a login name, and a password.
You should plan on setting aside 40 MB of disk space on the remote host
computer system disk. The actual amount of space the backup files will use
depends on the size of their PSAX system configuration files.
