VMware: Data Recovery – Failed to create snapshot for <server>, (vcb api exeption)

Last week we upgraded VMware Data Recovery from version 1.1 to 1.2. After rerun the backup schedule I received this error:

Failed to create snapshot for <server>. error –3948 ( vcb api exeption)


My backup starts > Create a new snapshot > Few seconds later… the snapshot is removed and get this warning..




Edit the VDR machine hostfile and add the ESX + vCenter server hosts by name and ip:

– Open the VDR console: login with Root / [email protected]

– Type: “vi /etc/hosts”

– Add your ESX hosts + name;

– : x to safe your configuration;


Rerun your backup schedule:


Backup is up and running 🙂

    I had the same problem and solved thanks to you!
    VDR simply search for esx servers by name, so you need a dns server that resolve that name.
    Alternatively you edit the /etc/host
    Thank you again!
