    Error trying to perform backup. Failed to open VDDK disk

    Ivanildo Galvão Hot Shot


      I've been working for two days on a problem, but no solution. Using Veeam Backup & Replication 9.5, Update 03.
      The same can not back up virtual machines, apparently for error of permission, but I have done everything or almost everything, according to articles I found on the internet.
      The error is this:


      Processing Apolo Error: Failed to open VDDK disk [[VMDATA02] Apolo / Apolo.vmdk] (is read-only mode - [true]) Logon attempt with parameters [VC / ESX: [calcario.vlb.local]; Port: 443 VMware Spec: [moref = vm-49]; Snapshot mor: [snapshot-146]; Transports: [nbd]; Read Only: [true]] failed because of the following errors : Failed to open disk for read. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.


      The error happens with all virtual machines.
      vCenter is VCSA 6.0, ESXi 6.0 hosts, Dell storage SAS type Compellent.
      I have already removed vCenter from Veeam and added again, using administrator@vsphere.local , the Veeam server, hosts and vCenter are on the same network segment. The Veeam is a physical server, Dell with 48GB of RAM and two processors.
      I already rebooted vCenter and also the hosts in order to restart the services, but it did not work.
      We opened call with Veeam, the only response Veeam sent was that it was a permission error, nothing more.


      Anyone have an idea how to solve this?


      Thanks !
