What is daily differential backup?
Daily backup refers to backing up data every day automatically. It's indeed a tight protection over important data, but can also lead to insufficient storage space if you are doing full backup everyday. In this case, differential backup is a better choice with its ability to back up only changed files based on the last full backup.
A daily differential backup, as a combination of the two, will automatically back up the changed files on daily basis. If you are considering doing it in Windows 10/8/7, there are some things you should know.
What are the advantages of daily differential backup?
Differential backup only backs up the changed and newly added data based on the last full backup. Thus with daily differential backup, you can:
Continuously protect the latest data every day.
Feel free to retrieve any of the versions with the last full backup plus the last differential backup.
Greatly save your time and storage space.
What are the other 2 backup types and how's differential backup different from them?
There are 3 generally accepted backup types - full backup, incremental backup and differential backup.
Full backup, as the name suggests, is the most basic backup type that will completely backup everything in the source directory, and requires much time and backup space at the same time. So we don't usually choose to perform full backup every day.
Incremental backup only backs up the changed or newly added data since the last backup, whether it's a full backup or not, while differential backup is based on last full backup.
In practice, each of these backup methods has advantages and disadvantages, you can refer to this differential backup vs incremental backup comparison.
