Challenge

Due to a known issue in rare cases Veeam Backup for Nutanix backups might get corrupted.

Cause

The issue appears on data read by libaio when memory is aligned by 512 bytes but not aligned by 4096 bytes. The issue can affect full backups as well as incremental ones.

Solution

The issue is fixed in Veeam Backup for Nutanix version 2.1 (build 2.1.396, see veeam.com/kb4117 for details). Please consider upgrading to version 2.1 to have your backup infrastructure immune. 

If you have Veeam Backup for Nutanix AHV version 2.0, it is sufficient to upgrade only the Veeam Backup & Replication AHV Backup Proxy, keeping Veeam Backup & Replication v10. See Installing Updates. If that update procedure fails please review vee.am/kb4150 for information regarding how to update the repository key.
