Which backup strategy copies all data at regular intervals, and when is it appropriate?

• A. Full backups copy only data that changed since the last backup.
• B. Full backups compress data to save space but do not restore easily.
• C. Full backups are created automatically every minute.
• D. A Full backups copy all data at regular intervals (simpler restores but longer to create).

Answer: (D)

Full backups are backups that copy all the data in the system at the moment the backup runs. Because they capture everything in one complete set, restoration is simple and fast—you can recover from a single backup without assembling data from multiple sources. This approach is best when you want straightforward restores and minimal risk during recovery, such as after setting up a new system or when you run periodic backups where the priority is quick, dependable recovery. The tradeoff is that a full backup takes longer to create and uses more storage, so many setups run full backups at longer intervals (like weekly) and use other types of backups between them to save time and space.
