How do incremental backups work

Day 2 — Schedule a differential backup. It will cover all the changes that took place between Day 1 and Day 2.

Day 3 — Schedule a differential backup. The first backup in an incremental backup is a full backup. The succeeding backups will only store changes that were made to the previous backup. Businesses have more flexibility in spinning these types of backups as often as they want, with only the most recent changes stored.

Incremental backup requires space to store only the changes increments , which allows for lightning-fast backups. For instance, if you have a high volume of data, you need a backup strategy that uses the combined power of a full and an incremental backup. These insights offer clarity for your SaaS backup buying process and can help you narrow down your search for the right backup solution that meets your backup needs.

You would now have a second version of the changed files.

Wednesday The backup software scans the backup selection and sends only the changed files from Tuesday. You would now have a second and third version of the changed files. New files created are also backed up. This is repeated each day and after 30 days you would have 30 different versions of changed files. You will also have the ability to restore any one of these files at any one of these backup dates.

This backup type reduces recovery reliability. It also becomes harder and takes longer to recover the whole data set, as it takes time to analyze and recover each backup in the chain.

That is why periodical full backups are highly recommended, in order to start a new sequence of incremental backups. The frequency of full backups depends on your business needs. You may want to conduct it weekly, monthly, or once every couple of months.

There is an advanced backup technique to simulate full backups, called a synthetic full backup. Further reading Synthetic full backup.

Backup software vendors usually let users set the number of versions of data they would like to keep. Incremental backup implies a full backup and a chain of subsequent increments and, in terms of versioning, every subsequent backup full or incremental is a version.

To provide data consistency, you cannot eliminate individual elements of this chain, only the entire series of the full backup and all the increments up to the next full backup. This is why we strongly recommend performing full backups periodically. There are different backup types that are determined by the size of changes that the software adds to the repository at every subsequent backup.

We will overview incremental file-level backup and incremental block-level backup in detail.
