What is the name of the backup technology that backs up only the changes that have been made to a file rather than backing up the entire file again?
What is the name of the backup technology that backs up only the changes that have been made to a file rather than backing up the entire file again?
For example, an incremental or differential backup would completely re-backup a file that had changed since the last full backup.
However, I have heard that there is a new more advanced technology than incremental or differential backups that will backup only the changes that have been made to the file that had previously been backed up rather than re-backing up the entire file.
Therefore whenever a restore is performed on a file that had been modified since the last full backup, the contents of the original full backup will be restored and then the restored file will be modified with the contents of the subsequent backups that contain the changes and modifications to the file.
Using this sort of backup technology is much more efficient and also results in much less overall space being used for storing full backups and the subsequent later backups.
