Differential backup (557 words) |
| The advantage of a differential backup is that it shortens restore time compared to a full backup or an incremental backup. |
| Restoring a differential backup is a faster process than restoring an incremental backup because only two backup container files are needed: the latest full backup and the latest differential. |
| The downside is if you run multiple differential backups after your full backup, you're probably including some files in each differential backup that were already included in earlier differential backups, but haven't been recently modified. |
