Challenge
After upgrading to v8 the following issues are observed with the existing jobs processing Hyper-V VMs with SCSI disks:
- First backup job run will transfer entire VM disks into the incremental backup storage. The following job runs will operate normally - regular incremental restore points will be created.
- First replication job run will create and attach the new, duplicate SCSI disk. After that, entire VM disk contents will be replicated to the newly attached disk. As a result, replica VM will start consuming 2x space on the target storage.
Cause
This is a known issue on v8
Solution
Install the following Critical update rollup for Veeam Backup and Replication 8.0.0.817 to address this issue.
