You perform a full backup on Sunday night and Incremental backups on Monday through Saturday night at 11:00 pm. Each incremental backup will copy only the data that has been modified since the Sunday backup was started. On Thursday, at 10:00 am, you had a disk failure. You replaced the disk drive (c4t0d0).
