Chapter 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.
