English to Chinese Tech/Engineering IT (Information Technology) deduplication

Another benefit of data deduplication is the ability to keep more backup sets on near line storage. With the amount of backup disk space reduced, more "point in time" backups can be kept ready on disk for faster and easier file restoration. This also allows you to maintain a longer backup history. ***Instead of having three versions of the file to restore***, users can have many more, enabling a very granular approach to file backups and accommodating loads of backup history.
