A further technology is Native Format Optimization (NFO) which, in contrast to deduplication doesn’t optimize information across files or blocks and in contrast to compression doesn’t change the output file format (which requires the performance-intense rehydration), optimizes unstructured file content within the single file. It can reduce the size of unstructured files by 50-90% without impacting e.g. dedupe on the backup.

Ahmed,

First, thanks for the comment and pointing out some challenges that come with any new technology. We have heard the same question from our customers. This is where the thing provisioning tools in storage come in handy. As long as the space is available – you can alway give the application more capacity.

Thanks again.
Steve

Deduplication is great, but it introduces a data mangement challenge when it comes to reducing storage utilization. Suppose I start running out of space on a volume and have to delete or migrate some data. Without deduplication, I know that if I delete 200 GB of files, that is the amount of space that will be freed up.

With deduplication, there is no way to tell how much actual space those 200 GB actually take up, and what other portions of data are dependent on them.
