What is AWS Backup?
It is a centralized and fully managed service that automates data protection across various AWS services like Amazon S3, Amazon FSx, Amazon EC2, and Amazon RDS, as well as hybrid workloads. It offers a policy-based solution with advanced capabilities, such as lifecycle policies for moving backups to a cheaper storage tier.
The service also provides audit and compliance reporting features, a vault lock for protection against deletions, and separate backup storage and encryption.
In simple terms, AWS Backup simplifies and centralizes the backup process, making data protection at scale easier and more affordable.
Backup and restore services are provided by AWS.
1. AWS Backup
A fully managed backup service offered by AWS, automates and centralizes data backups across a range of AWS services, including:
- AWS Storage Gateway volumes
- Amazon RDS databases
- Amazon EBS volumes
- Amazon EFS file systems
- Amazon DynamoDB tables
This service includes complex features like lifecycle policies, audit and compliance reporting tools, and vault lock for security against deletions, while also streamlining backup administration and doing away with the need to set up backups for each Amazon service separately.
AWS also provides block storage, file storage, object storage, and hybrid storage services that are useful for backup and recovery.
These services offer a full range of backup and restore options to satisfy data protection and compliance requirements when paired with AWS Backup.
2. Object Storage:
Amazon S3, their object storage option, can hold infinite amounts of structured and unstructured data. As a result, it has many data layers, and data that is viewed less frequently can be moved to an archive tier to reduce expenses. Because of Amazon S3’s query-in-place capabilities, businesses can perform real-time analytics on their data while it’s at rest. S3 Transfer Acceleration, which aims to facilitate rapid, secure data transfers over long distances, is another feature the service supports.
AWS provides two storage tiers within Amazon S3:
- Amazon S3 Glacier: It is a durable and affordable storage class for long-term backup and data archiving. This storage class is ideal for archives that are accessed often and require retrievability within minutes.
- Amazon S3 Glacier Deep Archive: It offers lower storage costs and is suitable for information that is likely to be accessed at most a couple of times a year.
3. Hybrid Storage:
- Amazon offers Storage Gateway as a hybrid storage management solution. With the help of this service, on-premises apps can establish connections with AWS storage services, including S3, S3 Glacier, and EBS.
- Using Storage Gateway, a company can send data via NFS and iSCSI, two popular storage interfaces, to the cloud. Three data formats are supported by the service: block storage (by EBS), object storage, and tape backup (via S3).
4. Block Storage:
- Persistent block storage volumes are provided by Amazon Elastic Block Store (EBS) and can be utilized with Amazon EBS instances. Each volume is automatically duplicated to protect against component failure.
- Businesses can scale up or down their use of Amazon EBS in a matter of minutes, and Amazon charges for each storage unit. Organizations can back up and safeguard data stored on Amazon EBS volumes with the help of a snapshot capability (snapshots are stored on S3).
5. File Storage:
- EFS, or Amazon Elastic File System, provides scalable file storage. Traditionally, mounted folders can be used to exchange files between EC2 instances connected to EFS. As it replicates the folder structure used in the on-premises system, this facilitates the migration of current applications to the cloud.
- Backup capabilities are integrated into Amazon EFS; it creates file system backups on its own by a preset schedule.

Components Of AWS Backup
1. Backup Plan
An expression of policy that specifies when and how to backup your AWS resources is called a backup plan. It will automatically create and store backups of the resources you designate for backup plans.
2. Backup Vault
- A backup vault in AWS Backup is a container used to store and arrange your backups. The AWS Key Management Service (AWS KMS) encryption key that is used to encrypt part of the backups stored in this vault needs to be specified when creating a backup vault. Their original AWS services are in charge of managing encryption for other backups.
- In any AWS Region where AWS Backup is accessible, new backup vaults can be established. Use AWS Backup Vault Lock to enable delete protection on the backup vaults to stop hackers from re-encrypting your files. With this, you can browse and recover your continuous backups and periodic snapshots as needed, all stored in the backup vault of your choice.
3. Backup Jobs
- Following the scheduled backup, the progress of the backup and further details such as backup, restore, and copy activities can be tracked.
- There are several backup job statuses: pending, running, aborted, completed, and unsuccessful.
4. Backup Audit Manager
- Built-in compliance measures are available in AWS Backup Audit Manager, and you may modify them to specify your data protection guidelines. It is intended to automatically identify and notify you of any violations of your specified data protection policy, along with the necessary remedial action.
- You may create audit reports that will assist you prove that you are in compliance with regulatory standards and regularly assess backup activities using Amazon Backup Audit Manager.
Creating and restoring Backups with AWS Backup
1. Creating a Backup
- Access AWS Backup via the Amazon console.
- Click “Create on-demand backup” on the dashboard.
- Select the resource type (e.g., DynamoDB) and specify the resource name/ID.
- Ensure “Create Backup Now” is checked for an immediate backup.
- Note “Transition to Cold Storage” and set backup expiration.
- Create or choose a backup vault.
- Select the IAM role for resource access.
- Enable “Windows VSS” for EBS volumes on Windows EC2 instances (if applicable).
- Proceed to the Jobs page to make the backup selection.
- View the backup job status using the appropriate Backup job ID on the Job Details page.
2. Restoring A Backup
- Using AWS Backup to restore an Amazon EBS volume:
- Select Protected resources from the AWS Backup panel, then click the ID of the EBS volume you want to recover.
- You can see recovery points for the chosen EBS volume under Resource Information. Go to the Backups pane and choose the radio button next to the recovery point you wish to restore to reinstate a resource. Choose Restore from the menu in the pane’s upper-right corner. Picture courtesy of AWS.
- Choose the restore settings based on the resource you have.
- Choose an availability zone and input the volume type and size under EBS volume.
Picture courtesy of AWS - Choose the IAM role that Amazon Backup should use for this restore operation under the Restore role.
- Choose Backup and Restore.
- The Restore Jobs pane will appear. A notice at the top of the page provides information about the restore task.
- AWS Backup and restore pricing
Backup Pricing:
When backing up an AWS-based data resource, the following pricing is applicable:
(Prices are for the US East Region and are subject to change; see the official pricing page for details.)
The costs listed below apply to heated storage:
- Monthly cost for Amazon EFS File System Backup: $0.05 per GB.
- Amazon EBS Volume Snapshot: $0.05 per GB per month

The only cold storage option offered by AWS Backup is for:
- Amazon EFS backups cost $0.01 per gigabyte per month—a substantial discount.
Restore Pricing:
Backup restoration for RDS, Storage Gateway, and EBS is free.
There is a cost for backing up backups with the following services:
(Pricing is for the US East Region and may change periodically.)
- Warm storage on Amazon EFS costs $0.02 per GB,
- Cold storage costs $0.03.GB of Amazon DynamoDB costs $0.15.
Limitations Of AWS Backup
- Lack of Backup Data Retention: It does not allow the archiving of EBS backups into reasonably priced S3 tiering, except for EFS compatibility.
- Lack of Automated Recovery Strategies: It does not provide recovery strategies, DR drills (without scripting), automation of DR drills, or customized restores.
- Lack of Network-Based Recovery: The inability to copy and capture Amazon VPC, which is crucial for guaranteeing high availability of your whole AWS infrastructure, is another important functionality that is absent.
- Lack of Granular Recovery: The availability of granular recovery options in AWS Backup may vary based on the service. For example, you might need to restore the entire filesystem if you’re using Amazon EFS and you just want to recover one file.
Common Use Cases of AWS Backup and Restore
1. Data Lifecycle Management:
- Features to manage your data at every stage of its lifecycle are supported by Amazon S3. S3 Storage Class Analysis is a useful tool for tracking data access trends and determining which data sets ought to be transferred to more economical storage classes.
- You can set up lifecycle rules to migrate a data set to an archival storage class or a less expensive storage class for optimal savings, based on the reports produced by S3 Storage Class Analysis.
- S3 Lifecycle Management policies can also be used to plan the deletion of items whose lives have come to an end.
2. Hybrid Data Protection:
- Numerous third-party backup services come with integrated cloud connectors that you can activate to transport backup data to AWS without interfering with your company’s regular business activities.
- Backup data is restored and made available for use in production by being brought back to the on-premises environment.
- Amazon S3, which includes the less expensive storage classes S3 Standard-Infrequent Access, S3 One Zone-Infrequent Access, S3 Glacier, and S3 Glacier Deep Archive, receives backups created on-premises, where the backup master server is housed.
3. Global Data Resiliency:
- The worldwide infrastructure offered by AWS is specially made to assist users in setting up and maintaining multi-regional architectures.
- Cross-region replication (CRR), a feature of Amazon S3, makes it easy to replicate S3 objects into several AWS Regions for disaster recovery, multi-region backup, compliance, and decreased latency.
- Replication also includes object tags, access controls, and metadata related to the original S3 object. The duplicated S3 objects reflect any further modifications made to the source item and its attributes.
Conclusion
