In this article, we will introduce the EBS backup method.
How to backup EBS
To create a backup of an EBS volume, you must use the
Snapshot feature must be used
The snapshot function is available on the
EBS can be backed up by creating a snapshot of the EBS volume in case of problems.
EBS Snapshot Features
EBS snapshots
are backed up using the incremental backup
method.
In other words, only blocks that have changed since the last snapshot are additionally stored.
This minimizes the time required to create snapshots
time required to create a snapshot is minimized.
and
storage cost savings.
This minimizes the time required to create snapshots and saves on storage costs.
When a snapshot is taken from an EBS volume, a snapshot is created in the region where the EBS is located.
It is not possible to specify where snapshots are created.
Therefore, a snapshot of an EBS located in a different region than the one you normally use will be created in the region where the EBS is located.
Use EBS periodic snapshots
EBS snapshots allow data on Amazon EBS volumes to be backed up to Amazon S3.
Snapshots are incremental backups.
That is, only blocks on the device that have been modified since the most recent snapshot are saved.
This minimizes the time required to create snapshots and saves storage costs.
Automated backups
Amazon Data Lifecycle Manager (Amazon DLM) can be used to automate the creation, storage, and deletion of snapshots, which are EBS backups.
Lifecycle policy for EBS snapshot acquisition can be set.
Protect valuable data by scheduling regular backups.
How can I be sure that my backups are really done?
Restoration is required after backup.
The reason is that it is necessary to confirm that they really have the same functionality.
Therefore, periodic restore training is required.
