Re: datadomain 中Globally Compressed和Locally Compressed的含义

There are two types of compression. 

  • Global compression (aka dedupe), which is the process by which we remove redundant data.
  • Local compression, which is the process of reducing the amount of space taken by data by using algorithms like gzip.
