There is an advanced backup technique to simulate full backups, called a synthetic full backup.įurther reading Synthetic full backup Versioningīackup software vendors usually let users set the number of versions of data they would like to keep. You may want to conduct it weekly, monthly, or once every couple of months. The frequency of full backups depends on your business needs. That is why periodical full backups are highly recommended, in order to start a new sequence of incremental backups. 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. This backup type reduces recovery reliability. This backup type requires less storage space and network load and can be run more often since there are usually a lot of small everyday changes in the data set that should be backed up. Week 3 - added and changed data only since the Week 2 backup. ![]() Week 2 - added and changed data only since the Week 1 backup.To demonstrate the backup process, let’s assume you have made a full backup and that now you would like to to do a weekly backup of any added or changed files: ![]() That is how this backup type gets its name: each backup is an increment for a previous backup.įurther reading Incremental and Differential Backup Comparison How Incremental Backup Works Unlike a full backup, where the whole data set is copied to the backup storage with every backup job, it allows you to perform a full backup only once in a while. ![]() This is a type of backup that copies only data that has changed since the previous backup. In this guide, we overview this concept, how it works, and how it helps save time and money on backup and disaster recovery routines. Incremental backup is a data backup method designed to reduce storage requirements and bandwidth load and provide the necessary level of data consistency and availability.
