Veeam Backup & Replication 10 Cumulative Patch 1 is a hotfix rollup that addresses the following issues reported by our customers on the original build of v10:

  • Defragment and compact functionality performs multiple passes on the same full backup for backup jobs that do not use per-VM backup file chains.
  • Querying WMI API class "Backup" fails with error code 0x80131500, which affects integration such as Veeam Service Provider Console (formerly Veeam Availability Console).
  • Start-VBRInstantRecovery PowerShell cmdlet fails to process restore points created by Backup Copy jobs.
  • VCSP rental license point weights were updated according to the March 1st 2020 changes.
NAS Backup
  • Copying NAS backups to secondary target erroneously consumes licenses (in addition to licenses consumed by the primary file backup job).
Object Storage
  • Capacity Tier copy policy may erroneously upload full backups to object storage periodically when source backup chains do not have periodic fulls. 
VMware vSphere
  • Resetting CBT on Active Full backup fails if the database contains orphaned ESXi hosts.
  • Deleting a vApp from vCloud Director backup may delete the entire backup if backup chain type was recently changed to per-VM backup.
Microsoft Hyper-V
  • Hyper-V backup jobs fail the "Object reference not set to an instance of an object" error in environments where at least one virtual machine is stored in the SCVMM Library.
  • Replica VMs disk space estimation logic may return incorrect value due to case sensitivity with virtual disk paths, resulting in some disks contributing to the total size twice.
  • SureBackup jobs using advanced multi-host virtual labs fail with the "Invalid configuration for device " error.
  • SureBackup log export functionality fails with the "Object was not found" error for SureBackup jobs that include an Application Group.
  • Backup to Tape job skips processing synthetic full backups with forever forward incremental source backup chains on days when full backup file merge happens.
