FAQ's
Are there any instances where data deduplication will not provide any benefits? Superior benefits?
a lot of new images being created, then you'll see very little benefit from data deduplication. In that case, you're better off just running differential or incremental backups.

As far as areas in which data deduplication can provide superior benefits, databases have a lot of redundant data and... More...

Is there a similar performance impact, or any impact at all, when restoring deduplicated data?
It really depends on how the index is constructed and how the data is laid out on the back-end disk. As long as the index can remain in memory, it can continue to process and find data as it's reconstructed.

The problem that begins to emerge is two-fold. First off, if you have backups going on at the same... More...

Are there any alternatives to server-free backup that address the same problems?
take a step back. Really, what is a backup? Its just an alternate copy of your data for restores. CDP and near-CDP solve the problem in a different way. They don't do the full backup or the nightly backup in the traditional sense. So CDP and near-CDP essentially remove the problems associated with large server... More...
