What file types does the Delta algorithm work on?
The Delta algorithm works well on a variety of file types. NOTE that the first backup is always a “master” or “full” backup. Subsequent backups take advantage of the Delta Processing scheme. Files that change very little, such as executable files, require virtually no backup activity. Most data files, especially databases, change relatively little during day-to-day operations and therefore lend themselves nicely to the Delta scheme which analyzes for blocks of the file that have changed since the last backup. It’s important to note that in addition Delta Processing data is also compressed reducing the amount of data transmitted even further.
