HP Archive Backup System for OpenVMS Guide to Operations

Overview
2.9 Getting Started
Before creating save or restore requests, you should first configure the media management environment.
This includes the tape volumes, drives, jukeboxes and other media management
objects that you may want to use. The recommended way to do this is to run the MDMS configuration
command procedure, which offers an online tutorial and help in defining the configuration.
During execution of this procedure, type “?” to get help on any question, and type “??” to
get help and (in many cases) a list of existing objects or possible values for answers to questions.
To invoke this procedure:
@MDMS$SYSTEM:MDMS$CONFIGURE
A complete example of running this procedure is provided in Appendix A.
Having completed the media management configuration, creating a save or restore request in
ABS can be very simple if you elect to use the default archives, environments and selection
objects. The minimum amount of information you need to specify for a save or restore request is:
• The name of the save or restore.
• The disks or files to be saved.
• The start time of the save.
ABS tries to determine the type of data being saved based on the format of the file specification
and assigns by default a relevant archive and environment. So, for example, a save request can
be specified and executed in a single DCL command as follows:
$ MDMS CREATE SAVE MY_SAVE/INCLUDE=DISK$USER1:[SMITH...]/START
This command creates a save called MY_SAVE, includes the file specification
DISK$USER1:[SMITH...] (all files), and starts the save immediately. MDMS determines that
this is a save of VMS files based on the file format, and assigns archive SYSTEM_BACKUPS
and environment SYSTEM_BACKUPS_ENV, and creates a default selection and schedule.
With this save definition, a default frequency of ONE_TIME_ONLY is assigned, and the save is
not scheduled for regular execution.
A restore can also be defined. For example, to restore the same files that were saved in
MY_SAVE, you can enter the following command:
$ MDMS CREATE RESTORE MY_RESTORE/INCLUDE=DISK$USER1:[SMITH...]/START
This command creates a restore called MY_RESTORE, includes the file specification
DISK$USER1:[SMITH...] (all files), and starts the restore immediately. MDMS determines that
this is a restore of VMS files based on the file format, and assigns archive SYSTEM_BACKUPS
and environment SYSTEM_BACKUPS_ENV, and creates a default selection and schedule.
With this restore definition, a default frequency of ONE_TIME_ONLY is assigned, and the
restore is not scheduled for regular execution.
Note
Define the logical referring to the disk name before executing the restore request. For
more information, see the note given in Section 3.5.8, “Destination (Restore Only)”.
Since these requests were defined with a frequency of ONE_TIME_ONLY, ABS will automatically
delete them after a default interval of 3 days after execution.
Of course, creating the backup environment to backup all data in your production environment
will involve more complex definitions, including creating your own archives, environments and
in some cases selections and schedules. Chapter 3, Saving and Restoring Data, describes all the
ABS objects in detail.
