What is the difference between an incremental and a differential backup?
What will be an ideal response?
An incremental backup will copy all files changed since the last full or incremental backup and mark these files as backed up. A differential backup will copy all files changed since the last full backup; but won't mark the files as being backed up.
When restoring an incremental backup, each backup since the last full backup must be restored in sequential order, ending at the latest incremental backup. With a differential backup, however, only the last full backup and the last successful differential backup need to be restored.
