Amazon boosts disaster recovery with snapshot feature addition
AWS users can now move EBS storage volumes between Availability Zones
Amazon has unveiled a new snapshot feature that could drastically reduce cloud downtime.
Amazon announced its new Elastic Block Store (EBS) Snapshot Copy in a discussion forum. The feature allows users to copy EBS snapshots across AWS regions.
It said the new feature would make it “easier for you to leverage multiple AWS regions and accelerate your geographical expansion, data centre migration and disaster recovery.”
Users can access the feature by going into the AWS Management Console, selecting the snapshot to be copied, set the destination region and starting the copy.
The feature can also be accessed via an EC2 Command Line Interface or an EC2 API as described in the EBS Snapshot Copy page.
The copied snapshot behaves the same as other snapshots in the destination region: it can be used to create new EBS volumes which can then be attached to an EC2 instance in the destination region.
Customers would only be charged for the data transferred to copy the snapshot and to store the copied snapshot at the destination region.
Amazon said it also plans to launch Amazon Machine Image (AMI) Copy as a follow-up to this feature, which will enable customers to copy both public and custom-created AMIs across regions.
The news comes after various problems AWS has encountered of late. The firm experienced a number of outages this year.
