4 Preparing the System
This chapter describes the procedures for notifying and preparing all the interactive items
of a system for a system level backup. The sections are:
• Notifying Users of Pending Backup
• Preventing New System Activity
• Sending Warning Messages
• Replying to Console Requests
• Temporarily Suspending Jobs
• Sending Final Warning Messages
• Aborting Any Remaining Sessions
For non-online backups, it is recommended that system backups be done when no one else
is using the system. This ensures that all files are backed up, since files open for write
access will not be stored.
For online backups, TurboSTORE/iX 7x24 True-Online Backup has two methods:
• Performing an
online backup (using the ONLINE option only), where users must be
logged off the system when the backup is started. Users can get back on the system
after the backup has started.
• Performing a
7x24 true-online backup (using the ONLINE option with START or
END), where you never have to ask users to log off of the system when doing a backup.
They can continue to access their files and applications throughout the backup.
available and can be modified while the backup is occurring. Refer to Chapter 7,
"TurboSTORE/iX 7x24 True-Online Backup," for more information.
The procedures in this chapter are recommended primarily for doing non-online backups.
Many of these steps do not need to be performed when doing an online or 7x24 true-online
backup.
NOTE Wherever the notes refer to an online backup, this means a backup being
performed with the ONLINE option. Where the notes refer to a
7x24
true-online
backup, this means a backup being performed with either the
ONLINE=START option or the ONLINE=END option.
To prevent users from accessing the system during a system backup, you must close all
files and log all users off of the system before you begin. It is also a good idea to announce
backups in the WELCOME message. To prepare for a backup, follow the steps below.
