Preparing For Disaster Recovery<br />
In case of a disaster you may need <strong>to</strong> res<strong>to</strong>re all or part of the on-disk data of your computing<br />
environment. Basically you need a bootable system disk and a complete ABS/MDMS environment<br />
<strong>to</strong> res<strong>to</strong>re all the rest of your data. This chapter explains the task <strong>to</strong> get you ABS environment<br />
up-and-running from scratch. The procedure differs slightly between <strong>OpenVMS</strong> and non-<br />
<strong>OpenVMS</strong> systems.<br />
7.1 Disaster Recovery <strong>for</strong> <strong>OpenVMS</strong> <strong>System</strong>s<br />
To recover from a <strong>to</strong>tal loss of your online data you need the following items <strong>for</strong> recovery:<br />
c. An image copy of your system disk<br />
d. A copy of your MDMS$ROOT including the database files<br />
e. A copy of your ABS$ROOT including all catalog files<br />
f. A copy of files of any other product required by ABS, such as your 3rd party scheduler<br />
product<br />
In all cases you need <strong>to</strong> keep the in<strong>for</strong>mation about the saves in a safe place. This in<strong>for</strong>mation is<br />
in the ABS save log and includes:<br />
a. The volume IDs of the tapes used<br />
b. The name of the savesets created<br />
c. The source path of the files being saved<br />
Note<br />
It is important <strong>to</strong> note the full pathname of the original location of the files.<br />
You can print out this in<strong>for</strong>mation from the epilog procedure of the environment.<br />
7.1.1 <strong>Backup</strong> of Your <strong>System</strong> Disk<br />
The easiest way <strong>to</strong> save your system disk is by using an ABS SAVE object like this:<br />
Example 7–1 Save Object <strong>for</strong> Disaster Recovery of <strong>System</strong> Disk<br />
