@34158 The problem in most cases is that there are no clearly defined policies around data. We just buy more storage...
because we know storage is cheap now and we just keep adding to it. I've said that cheap storage equates to procrastination when it comes to retention policies. So, ultimately it's important to understand the data that you have and then identify what you need to keep and how long you need to keep it. If you keep everything forever, your mass of storage will just keep growing making data, particularly unstructured data, more difficult to manage.
Retention should employ practices, like data classification and information lifecycle management (ILM), to help identify the data on hand. Then, use that knowledge to determine the appropriate retention, archiving and deletion strategies for your industry and specific business.
