Abstract
Avoiding encryption in a deduplication vault. In one example embodiment, a method for avoiding encryption during a backup of a source storage into a deduplication storage may include analyzing an allocated plain text block stored in the source storage at the point in time to determine if the allocated plain text block is already duplicated in the deduplication storage, in response to the allocated plain text block already being duplicated in the deduplication storage, avoiding encryption of the allocated plain text block by skipping an encryption of the allocated plain text block and instead associating the location of the allocated plain text block in the source storage with the location of the duplicate block already duplicated in the deduplication storage.
