If you are on a domain the user name must be written in the format Domain/Username. Also make sure that the user name and password that you entered are the ones for the user logged onto the machine when the backup job is intended to run.
GBM uses Windows Scheduled Tasks agent to schedule unattended backup jobs, make sure that the Scheduled Tasks agent is active by manually creating a scheduled task and running it once. For instructions on how to do this, please follow the link below:

In most cases, the user will get an error message that reads
“0x8007007a: The data area passed to a system call is too small.”
This indicates that the buffer that stores account information for ALL scheduled tasks is finite, and has been exhausted.
To workaround this error:

  1. Copy / Paste the following into notepade and save the file as StopStartTaskScheduler.bat in the root C: directory:
    1. @echo off
    2. net stop “Net Logon”
    3. net stop “Windows Time”
    4. net stop “Task Scheduler”
    5. net start “Windows Time”
    6. net start “Net Logon”
    7. net start “Task Scheduler”
    8. @ping -n 901 127.0.0.1>nul
    9. @echo You may set the account information for the ‘new task’ and schedule additional tasks.
  2. Open a CMD prompt,to do this go to Start – All Programs – Accessories – Command Prompt
  3. Type c:\StopStartTaskScheduler.bat and press Enter.
  4. In 15 minutes, the Task Scheduler scavenger tool, which start 10 minutes after the Task Scheduler service is started, should have freed enough buffer memory, and you would be able to schedule a new task successfully.

NOTE: You may have to press OK in a dialog that tells you that some scheduled tasks have been missed.
NOTE: When the script starts the Task Scheduler, it is normal to receive:
The requested service has already been started.
