Here is an example of incremental backups.
On Sunday, you save a backup of a word document. You continue to work on that document on Monday, Tuesday, and Wednesday. Each day, only the new updates on that day are saved to the backup.
On Monday – Monday’s updates are saved.
On Tuesday – Tuesday’s updates are saved.
On Wednesday – Wednesday’s updates are saved.
This continues until next Sunday when you do another full backup.
If you were to recover the document in full on Wednesday the document would need four things – The full backup from Sunday and Monday’s, Tuesday’s, and Wednesday’s updates.
Compare this to Differential backups above.
Differential – Quicker Recovery
Incremental – Quicker Backup« Back to Glossary Index
