Full Backup: A full backup is a copy of all files from one location to another. Although, this is a very safe and straight forward method, it takes a long time to complete and consumes lots of storage space. Some backup systems refer to this method as a copy backup. A full backup resets the archive bit.

For example: A company finds that their data hardly change on a daily basis and decides to perform a full copy (backup job) of their folders and files on a weekly basis. They decided to call this backup job as ‘Weekly Full’ and used a remote storage location as the backup destination. Also, they may want to have a back-storage of four weeks such as, Weekly 1 Full, Weekly 2 Full, Weekly 3 Full and Weekly 4 Full. Then on Week 5 they start again from Weekly 1 as to rotate their backup job over four weeks. With this strategy they can go back to weekly restores to a maximum of four weeks. Read more »
