How Was This Full Made? — TechKnowSurge

About this interactive

A synthetic full backup is a full and incrementals combined. A full backup runs once, say at the start of the day, and incrementals run through the day. The synthetic backup takes those incrementals and rolls them into the full after the fact, so there is always an up-to-date full to restore from in one step. The lesson gives two benefits: the full only has to be taken once, and a full copy is still available at any point. A traditional full is read from the source every time it runs. It is the simplest to restore, but on a large system it can take a whole weekend and slow everything down while it runs.

What you'll learn

Tell a synthetic full backup (built afterward from an earlier full and the incrementals since) from a traditional full (read in full from the source), by how it is made and what it costs the source system

Key terms

Synthetic Full Backup: A backup type that combines a previous full backup with subsequent incremental backups to construct a new full backup without reading from the source system again.
Full Backup: A complete copy of all selected data, serving as the baseline backup type from which other backup strategies operate.
Incremental Backup: A backup type that copies only the data that has changed since the last backup of any type, minimizing storage use but requiring multiple restore steps.
