Data Backup And Data Snapshot Difference

AWS Backup VS Snapshot
Posted on: Jul 6, 2019 7:43 PM
Hi, Guys
Want to know how much difference between AWS Backup and normal manual snapshots?
I know that snapshots could have data inconsistency problem if a snapshot is created when it is still in use. So stopping and unmounting the volume before creating screenshot is recommended.
Is AWS Backup smart enough to handle the inconsistency problem properly?

I understand you would like to know the difference in the features of AWS Backup and the normal volume snapshots regarding the data inconsistency.
Today, several AWS services offer backup features that help you protect your data, such as EBS snapshots, RDS snapshots, DynamoDB backups, and Storage Gateway snapshots. All existing per-service backup capabilities remain unchanged. AWS Backup provides a new, common way to manage backups across AWS services both in the AWS Cloud and on premises. AWS Backup supports existing backup functionality provided by EBS, RDS, DynamoDB, and Storage Gateway.
So AWS Backup is a service which you can use to centrally manage all the resource backups. However, the features and functionality of the specific resources will remain the same. For example, when you create a backup plan, AWS Backup uses the EBS snapshot capabilities when creating backups on your behalf according to your backup plan.
Hence the feature of handling the data inconsistency is not in the hands of the AWS Backup service.

Snapshot Backup Software

  1. 'Backups' and 'snapshots' are terms that you may often hear in the web hosting space. They seem similar, but they are not the same. While both do make copies of your account information, they do so in different ways. Backup A backup is a copy of your data.
  2. A snapshot only needs to save enough information to undo a change and that makes it take less space than a backup. How do QNAP’s block-level snapshots work? When you take a snapshot, the metadata recording where each block of data is stored is copied to the snapshot. This takes very little space and the snapshot is created very quickly.
  3. What Is the Difference Between AWS Snapshot and Backup? Ever-increasing amounts of business-critical data, particularly in virtualized environments and in the cloud, have shaped the need for reliable data protection technologies.
  4. In contrast, the purpose of a backup is to store data in the short and medium term, providing a regular snapshot of the data in question. This concept allows copies of whole data sets to be made so that they can be swapped out to external storage or a cloud environment and restored at a later date.

VM snapshots are a simple and effective way to roll a virtual machine back to a point in time. Mistakenly, some still view snapshots as a backup because they allow a VM to return to a previous state. Snapshots are not backups. It is dangerous to consider VM snapshots an actual backup copy of data.
