Resolved Issues

A changed block tracking anomaly may result in restored VMs failing to boot. Stale backup snapshots are not removed from the Veeam Backup & Replication database after a job run. Now, the Veeam Backup & Replication database will retain only the latest backup snapshot for each VM in a job. VeeamZIP may fail for a VM if a previous VeeamZIP of that same VM was copied to the same destination using the Copy Backup feature. Abnormal backup agent termination resulting from worker out-of-memory condition. Backup processing fails for VMs with disk volumes smaller than 1MB. When attempting to create an AHV backup job that targets an HPE StoreOnce repository using the Veeam Backup & Replication Console, an error occurs, and the job cannot be created. The job wizard in the Veeam Backup & Replication Console fails to open after a previously standalone repository is added as an extent to a SOBR. Other minor security fixes.
