Veeam Backup for AWS CBT Potential Data Corruption

Challenge

When you try to back up EC2 instances residing in AWS regions with the supported CBT mechanism, you may get corrupted backup data.

Cause

The issue occurs in AWS regions where Amazon EBS direct APIs for Snapshots are available.

When Veeam Backup for AWS performs an incremental backup session, and the new cloud-native snapshot contains a large block of existing but unmodified data, all changes in other data blocks following this block may be skipped.

Solution

This issue has been resolved in Veeam Backup for AWS v2 Patch 1.
