Amazon Elastic Block Store (EBS)

Amazon Elastic Block Store (Amazon EBS) provides persistent block level storage volumes for use with VMs in the Amazon Web Service (AWS) Cloud.

Each AWS EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. You can run discovery on both your EBS volumes and EBS snapshots. AWS Elastic Block Store requires the Amazon Web Services plugin.

Discover an EBS volume

You can run discovery on both your EBS volumes and EBS snapshots.

About this task

An Amazon EBS volume is a durable, block-level storage device that you can attach to a single VM. You can use Amazon EBS volumes as primary storage for data that requires frequent updates, such as the system drive for an instance or storage for a database application.

Amazon EBS volumes persist independently from the running life of a VM. After a volume is attached to an instance, you can use it like any other physical hard drive. Amazon EBS provides the following volume types: General Purpose (SSD), Provisioned IOPS (SSD), and Magnetic.

Discover an EBS snapshot

You can run Discovery on both your EBS volumes and EBS snapshots. Discovery can be full or targeted. Snapshot ID or Volume ID should be provided to do targeted discovery.

About this task

Amazon EBS provides the ability to create snapshots (backups) of any Amazon EC2 volume and write a copy of the data in the volume to Amazon S3, where it is stored redundantly in multiple Availability Zones. The volume does not need be attached to a running instance to take a snapshot. As you continue to write data to a volume, you can periodically create a snapshot of the volume to use as a baseline for new volumes. These snapshots can be used to create multiple new Amazon EBS volumes, expand the size of a volume, or move volumes across Availability Zones. Snapshots of encrypted Amazon EBS volumes are automatically encrypted.

A new volume created from a snapshot is an exact copy of the original volume at the time the snapshot was taken. Amazon EBS volumes that are restored from encrypted snapshots are automatically encrypted. By optionally specifying a different volume size or a different Availability Zone, you can use this functionality to increase the size of an existing volume or to create duplicate volumes in new Availability Zones. You can share snapshots with specific AWS accounts or make snapshots public. When you create snapshots, you incur charges in Amazon S3 based on the volume's total size. For a successive snapshot of the volume, you are charged only for additional data beyond the volume's original size.
