In AdvancedCopy Manager, backup or restore processing must be performed while transaction volumes are unmounted. Therefore, when backup or restore is executed, mount and unmount processing of the transaction volume is done using the pre-processing and post-processing scripts.
AIX AdvancedCopy Manager implements the transaction volume unmount/mount operation by customizing pre-processing and post-processing scripts. If a pre-processing script terminates with an error during execution of backup/restoration, backup/restore processing is not performed.
Pre-processing and Post-processing scripts for Backup need to be customized in the following conditions.
The backup target is a volume group
To add special pre-processing and post-processing to the corresponding scripts.
For information about the customization method, refer to "Appendix A Pre-processing and Post-processing of Backup and Restoration" for more information.
Point
Where there has been an upgrade to existing versions of AdvancedCopy Manager or its components, any scripts used with AdvancedCopy Manager or its components should be reviewed and customized accordingly after upgrading rather than continuing to reuse scripts from previous versions.
