Issue/Introduction

When doing a DX NetOps upgrade of the Data Aggregator, backup files are automatically generated in the /opt/IMDataAggregator/backup directory when the installer is run.
This directory can be very large and cause disk space problems.  

Environment

All supported DX NetOps Performance Management releases.

Resolution

The /opt/IMDataAggregator/backup directory will be used to:

- save the ActiveMQ installation from under /opt/IMDataAggregator/broker/apache-activemq-*
- save the karaf installation from under /opt/IMDataAggregator/apache-karaf-*

If the installation being upgraded have large activemq.log files under /opt/IMDataAggregator/broker/apache-activemq-*/data, or many data.bak* directories under /opt/IMDataAggregator/apache-karaf-*, then we can clean those extra activemq.log files or extra data.bak* directories before starting the upgrade.

Also, check the /opt/IMDataAggregator/apache-karaf-* directory and its sub-directories for any *.hprof files (these are OutOfMemory dumps that may have been created).  
Those can be deleted as they are probably old and no longer of use for debugging purpose.
