Use Amazon EBS, you can create a point in time snapshot of the volume, we will for you in store in Amazon S3. In the Amazon S3 replication (snapshot to create a snapshot of the state and has been completed to completed time), you can copy the snapshot AWS from one area to another can also be copied in the same area. Amazon S3 server encryption (256 AES) may be protected in the snapshot data transmission during the copy operation. Snapshot copy with the original snapshot ID will get a different ID.
To copy a multi-volume snapshots to another AWS region, please use the snapshot you apply the tag to retrieve multi-volume snapshot group at the time of the snapshot. The snapshots are then copied to another area.
Use Cases
-
Geographic expansion: Start your application in the new AWS region.
-
Migration: Migrating applications to new areas, in order to achieve better availability and minimize costs.
-
Disaster Recovery: Backup your data regularly and logs in different geographical locations. When a disaster happens, you can use the point in time the auxiliary storage area of backup and recovery for your application. This operation allows data loss and recovery times to a minimum.
-
Encryption: prior to encrypt unencrypted snapshot, change the encryption key to encrypt a snapshot or snapshots to share with you, create your own copy of the snapshot from which to restore the volume.
-
Data retention and audit requirements: encrypt your EBS snapshot replication from one account to another AWS AWS account, in order to retain log data or other files, easy to audit or data retention. Use a different account to help prevent accidental deletion of snapshots, and provide protection for you if your main AWS account has been compromised.
Incremental replication across the region
The first snapshot is copied to another area of the copy is always a complete copy. Copy the data changed for non-encrypted snapshot, with each subsequent snapshot copy of a copy of a volume are incremental, which means that AWS only from the last snapshot replication since the same target area. This speed of replication and reduces storage costs.
In the case of an encrypted snapshot, you must use to encrypt and CMK previously used to obtain a copy of the same incremental copies. The following example illustrates how it works:
-
If unencrypted snapshot from the eastern United States (Northern Virginia) region to the western United States (Oregon) area, the first snapshot copy is a complete copy, and incremental copies in subsequent snapshot copies of the same volume of the same inter-regional transmission.
-
If encrypted snapshot from the eastern United States (Northern Virginia) region to the western United States (Oregon) area, the first snapshot copy of the volume is a complete copy.
-
If you use the same encryption CMK snapshot copies of the same in the subsequent volumes between the same area, the copies are incremental copy.
-
If you use a different encryption CMK snapshot copies of the same in the subsequent volumes between the same area, the copy is a complete copy of the new snapshot.
