Key Concepts Of AWS Backup Service

Hello Everyone

Welcome to CloudAffaire and this is Debjeet.

Backup is one of the most critical components of your infrastructure. Proper backup plan can make or break your business and this is particularly true when dealing with any public cloud service provider. In AWS, most of the services that deals with your data offers their own backup solution.

Key Components Of AWS Backup Service:

Backup Plan:

  • Backup Frequency: How often the backup is taken.
  • Backup Lifecycle: How many days the backup will be available to restore.
  • Backup Window: When to take the backup.
  • Backup Vault: A container where your backups are stored and organized.

Backup Vault:

A backup vault is a container that stores and organizes your backups. AWS Backup service will always have a default backup vault, but you can also create additional backup vault based on your backup plan. Backup vault also supports encryption to protect your backups.

Backup & Restore Jobs:

Whenever a new backup or restore is triggered a job is created. You can monitor the current status of a backup of restore using Jobs.

Backup Audit Manager:

You can use AWS Backup Audit Manager to audit the compliance of your AWS Backup policies against controls that you define. A control is a procedure designed to audit the compliance of a backup requirement, such as the backup frequency or the backup retention period.
