A company performs a full backup of their servers every Sunday night. On Monday, a differential backup is performed. If the server crashes on Thursday morning, which backups will be required to restore the server to the most recent state?
The full backup from Sunday and the differential backup from Monday
All incremental backups performed since Monday
The full backup from Sunday and the differential backup from Wednesday
The full backup from Sunday and all incremental backups performed since then
To restore the server to its most recent state after a crash on Thursday morning, you need the full backup from Sunday and the differential backup from Monday. Differential backups capture all changes since the last full backup, so the Monday differential includes all changes made up to and including Monday.
The full backup from Sunday and the differential backup from Wednesday is incorrect, as the question states the available backups are from Sunday and Monday, not Wednesday.
