A payroll server has data on it that needs to be readily available and can be recovered quickly if something is accidentally removed. Which of the following backup methods should be used to provide the fastest data recovery in this situation?
Explanation:
A full backup creates a complete copy of all the data on the server. Since all the data is stored in a single backup set, recovery is fast and straightforward because it doesn't require combining data from multiple backup sets (as some other methods do). This makes it the best option for situations where data needs to be readily and quickly recoverable.
What the other methods mean:
B. Differential:
Backs up all changes made since the last full backup.
Recovery requires the full backup plus the latest differential backup, which makes it slower compared to a full backup.
C. Synthetic:
Combines full and incremental backups into a "synthetic full backup" stored on backup media.
While it helps save time during backup creation, recovery involves reassembling data, which can slow down the process.
D. Incremental:
Backs up only the changes made since the last backup (either full or incremental).
Recovery requires combining the full backup and every incremental backup taken since then, making it the slowest method for data recovery.
... Incremental backups have the fastest backup speeds because they only back up the data that has changed since the last backup, regardless of whether it was a full, differential, or another incremental backup. This reduces the amount of data being copied, making the backup process quicker.
Gemini:
Full Backups and Recovery Speed: A full backup creates a complete copy of all data on the server at a specific point in time. Because it's a complete copy, restoring data from a full backup is typically the fastest method. There's no need to combine multiple backups or rely on incremental changes since you have a full image of the server's data at the time of the backup.
For the fastest data recovery, A. Full backups are typically the most suitable option.
Full backups create a complete copy of all data at a specific point in time, making the recovery process straightforward. When restoring from a full backup, you only need to access one backup set, which simplifies and speeds up the recovery process compared to other backup methods.
Differential, synthetic, and incremental backups all involve storing only changed or new data since the last backup, which means that during the recovery process, you might need to access multiple backup sets to restore the data to its most recent state. While these methods are efficient for minimizing storage space and backup time, they may not be as fast for data recovery as a full backup.
