Symptom
The following error message pops up after upgrading buagent:
"Backupdriver version to old, please upgrade to driver 3.1 or newer."
Cause
The reason is because the backupdriver currently in use isn't matching with buagent version. Running the following command will confirm this if it also states older version of backupdriver message:
# buagent /etc/buagent/agent_config
Resolution
(unlock the module, in case it's a version that had this feature)
# buagent -u
(remove the module from the kernel)
# rmmod backupdriver
(download or build a new module)
# r1soft-cki
(start the agent)
# buagentctl start
