Abstract
Avoiding compression of high-entropy data during creation of a backup of a source storage. In one example embodiment, a method for avoiding compression of high-entropy data during creation of a backup of a source storage may include identifying a chunk with an original size in a file in a source storage, compressing, during creation of a backup of the source storage, the chunk to generate a compressed chunk with a compressed size, determining a compression ratio for the chunk by comparing the original size to the compressed size, determining whether the compression ratio is less than the compression threshold, and, in response to determining that the compression ratio is less than the compression threshold, automatically designating the file as a high-entropy file and automatically avoiding compression, during the creation of the backup, of chunks in a second similar file in the source storage.
