INCREMENTAL BACKUP
An incremental backup is a type of backup that only copies files that have changed since the last backup. If a full backup was done on Monday, Tuesday's, incremental will backup files that have changed since Tuesday's incremental backup.
The main advantage of incremental backups is that fewer files are backed up daily, allowing for shorter backup windows. The disadvantages is that during a complete restore, the latest full and all subsequent incremental backups must be restored, which can take significantly longer.
DIFFERENTIAL BACKUP
A differential backup is a type of backup that copies all the data that's been changed since the last full backup. The size of a differential backup grows throughout the week and becomes progressively larger until the next full backup. A full restore from this type of backup only requires the last full backup and the last differential.
