Copy Snapshot From One Region to Another- Copy Snapshot Cross Region/Account

In Amazon EBS, you can easily create snapshots of your volumes, capturing a moment in time for your data. These snapshots are securely stored in Amazon S3. Once a snapshot is complete, you have the flexibility to copy it to another AWS Region or within the same Region. During this copy process, Amazon S3 ensures the data's security with server-side encryption.

Key Points

  • Every copied snapshot receives a unique ID, different from the original snapshot.
  • To copy multi-volume snapshots across Regions, identify them using the applied tag and copy each snapshot individually.
  • If you want another account to copy your snapshot, adjust the snapshot permissions accordingly or make it public.
  • Launch applications in a new AWS Region effortlessly.
  • Move applications to enhance availability and reduce costs.
  • Safeguard data across regions, enabling quick application restoration in case of a disaster.
  • Modify encryption, change encryption keys, or create a copy for creating volumes from shared, encrypted snapshots.
  • Copy encrypted EBS snapshots to preserve data for auditing or retention, adding an extra layer of security.

Considerations to Keep in Mind:

  • A limit of 20 concurrent snapshot copy requests per destination Region exists. Wait for ongoing requests to finish before initiating new ones.
  • Tags from the source snapshot aren't automatically copied. Add user-defined tags during or after the copy operation as needed.
  • Snapshots created during a copy operation have arbitrary volume IDs (e.g., vol-ffff), which shouldn't be used for any specific purpose.
  • Permissions specified for the copy operation apply only to the new snapshot, not the source snapshot.

Copying a snapshot is a straightforward process, and here's a guide to help you through it:

  1. Open the Amazon EC2 console by navigating to https://console.aws.amazon.com/ec2/.

  2. In the navigation pane, select "Snapshots."

  3. Pick the snapshot you want to copy, then go to "Actions" and select "Copy snapshot."

  4. Enter a brief description for the snapshot copy. The default description includes details about the source snapshot, aiding in easy identification. Modify it if necessary.

  5. Specify the Region where you want to create the snapshot copy.

  6. Determine the encryption status for the snapshot copy.

    • If the source snapshot is already encrypted or your account defaults to encryption, the copy is automatically encrypted, and this setting cannot be changed.
    • For unencrypted source snapshots and accounts without default encryption, you have the option to encrypt the copy. Choose "Encrypt this snapshot," and select the desired KMS key for encryption in the destination Region.

  7. Click on "Copy snapshot" to initiate the copying process.

After completing the process, you'll find a newly created snapshot in the selected region, ready for your use.
