Instant VM Recovery Lease Timeout

Have you ever tried to perform an instant VM recovery and the VM just refused to publish yet when you try smaller VMs it is successful?

The problem may be the Instant VM recovery lease is timing out which can be caused by a number of factors.

  • VM with large disks attached
  • Large backup chain
  • Slow storage
  • Deduplication on the storage

To increase the lease timeout, you need to create two registry entries which go under ‘HKLM\SOFTWARE\Veeam\Veeam Backup and Replication’

IrMountLeaseTimeOut (REG_DWORD) value (default one is 30 minutes).
IrVcdMountLeaseTimeOut (REG_DWORD)

VM Instant Recovery Reg

To take effect, you must restart the Veeam Backup & Replication service.
