Setup Wizard ended prematurely because of an error

Challenge

When upgrading to Veeam Backup for Microsoft Office 365 v2 from an earlier version the following error is received:


Additionally, the latest Veeam.Archiver.Service log file found under C:\ProgramData\Veeam\Backup365\Logs contains the following:

25.7.2018 10:14:12    6 (5940)   Upgrading backup jobs...
25.7.2018 10:14:12    4 (4588) Error: Job with the specified name already exists.
25.7.2018 10:14:12    4 (4588) Type: System.Exception
25.7.2018 10:14:12    4 (4588) Stack:
25.7.2018 10:14:12    4 (4588)    at Veeam.Archiver.Controller.JobConfigVerifier.VerifyCreatedJob(JobConfig config, BackupScopeConfig

Cause

Under rare circumstances records on backup jobs might be duplicated in a configuration database. This does not affect an already existing installation, yet fails a duplicates check during the upgrade.
 

Solution

Please contact Veeam Technical support for the fix.
