During further discussions, the 3-2-1 rule was recommended. What is the most efficient way to protect primary and secondary sites following the 3-2-1 rule?

Question

Options

• AFrom existing backups at the primary site, create a backup copy to the secondary site. Offload
• BSend replicas directly from the primary to the secondary site. Backup replicas on the secondary
• CSend backups directly from the primary to the secondary site, avoiding duplicate data storage. Tier
• DUse storage snapshot support to backup a virtual machine using the secondary array. Backup

• A
  80% (28)
• B
  11% (4)
• C
  6% (2)
• D
  3% (1)

Explanation

Option A follows the 3-2-1 rule by having three copies of data (the original production data, the backup at the primary site, and the backup copy at the secondary site), two different media types (local disk and object storage), and one copy off-site (the backup copy at the secondary site). This option also reduces the amount of traffic sent over the network by using existing backups as seeds for backup copies, and reduces the storage costs by using cloud tier to move older backups to cheaper and unlimited cloud storage.
