Types of Data Backup: Full, Incremental, Differential

Types of Data Backup: Full, Incremental, Differential

Data backup, storage and recovery are integral to the protection of your business’ most important assets. Every business or every size must have some form of data backup in place.

Data backup serves two distinct purposes:

  • Data recovery due to deletion or data corruption
  • Data recovery from an earlier time for data retention policies, compliance, etc.

In order to take advantage of the the full benefits of cloud backup, and as a matter of best practices, business need to delineate between essential and non-essential data. The type of data being backed up will determine backup policy, including when and how the data is backed up.

Backup types can vary among businesses and typically fall into the following primary categories:

FULL BACKUP
Full image backups contain several gigabytes of storage and generally include personal and operating system files and applications. When subsequent backups are run, the entire list of files and will be backed up again. Restores are easy because everything is backed up in one set, different versions are easy to maintain and restore. However, this type of backup is time consuming and consumes large amounts of storage.

INCREMENTAL BACKUP
Incremental backup creates copies of files, or parts of files, only data that has changed or been added since the last backup (full, differential or incremental). Typically, a full backup is done and subsequent backups are incremental. This type of backup is faster and uses less storage than full backup; however, restores can be slower and more complicated than other types of backups because it may require several sets of data to fully restore all the data.

DIFFERENTIAL BACKUP
Differential backup is a backup of all changed and new files since the last full backup. This method uses less storage and takes less time than a full backup. It offers faster and simpler restores then incremental backup. However, this type of backup may contain a lot of duplicate files which is not as an efficient use of storage space as compared to incremental backups. All files added or edited after the initial full backup will be duplicated again with each subsequent differential backup. For restoration, you will only need the the last full backup, and the last differential backup.
