Problem: Cisco CallManager User Cannot Upgrade, Install, or Un-install BARS
The Cisco CallManager user cannot upgrade, install or un-install BARS. The user receives this error message:
BARS can not be upgraded/uninstalled because it is
in the middle of a BACKUP/RESTORE operation
Solution
This problem can occur due to a failed backup, or there can actually be a backup in progress. If you are certain there is not a backup in progress and the system is still stuck, use this workaround:
Complete these steps on the Cisco CallManager server:
1.
Make a backup of the registry. Ensure that Cisco Security Agent (CSA) and all antivirus software is disabled.
2.
Change the \HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems\BARS\information\AppStatus registry key value from BACKUP to IDLE.
3.
If this procedure does not stop the BARS activity, remove the registry entry \HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems\BARS\Information\Appversion = X.0.X000. Reboot the Cisco CallManager only after you have removed this registry value (if it is not present in Add/Remove Programs) and then try to install BARS.
hth,
