Issue/Introduction
Symptoms:
- Veeam replication is used to replicate the VM data between source and destination sites.
- After making a disk change on the source VM, the next replication run causes all the existing restore points to be deleted.
Error Message noticed on Veeam Software : VM disk size changed since last sync, deleting all restore points
Environment
- VMware vSphere ESXi 7.0.x
- VMware vSphere ESXi 8.0.x
Resolution
As per the Veeam Document, Veeam Backup & Replication - Considerations and Limitations. it states that the issue is due to VMware vSphere limitations, If you change the size of VM disks on the source VM, Veeam Backup & Replication deletes all available restore points (represented as VM snapshots) on the VM replica during the next replication job session. For more information, see this VMware KB article. i.e. KB # 323136.
Based on our observations, there are no known limitations from vSphere and not recorded in the Knowledge Base article 323136, which is referenced in the Veeam document Replica Limitations. It appears that this was previously tested regressively, and the feature could not be certified, which led to it being marked as a vSphere limitation in the document. However, both products are functioning as designed.
