UCCX Backup failed

Hi everyone,

I have a UCCX backup failed issue with one of our clients.

It's a UCCX 5.0(1)-SR02ES08-Build083. When i tried backup, the bar stopped at 5% and the error message is like this:

Unable to contact Call Manager. Please make sure that the Call Manager is running and connected to the network; nested exception is: Fail to acquire bootstrap mutex; nested exception is: can not acquire ClusterMutex; nested exception is: Get config record - error: catch cisco.config.ConfigException UnmarshalException; nested exception is: javax.xml.bind.UnmarshalException: Premature end of file. - with linked exception: [org.xml.sax.SAXParseException: Premature end of file.], refer to the MCVD logfiles for more details

Can anyone give me some idea?

I suggest you to use bars from call manager.

Re: UCCX Backup failed


did you find the solution for this problem (other then using BARS from CUCM)?

I have the same problem on version 5.0(2)_SR02ES11_Build110.

any ideas would be appreciated.

Re: UCCX Backup failed

This is a known issue. Workaround is to STOP the CSA and run the backup schedule.

Re: UCCX Backup failed


Most common reason for the backup to fail is due to lot of RAW files in the folder "c:\program files\cisco\desktop_audio"

If there is more than 2 GB data in that folder I will suggest you to manually remove those files and see if the backup goes through. If its HA check both the servers



Re: UCCX Backup failed

The error message itself is fairly generic.

If its failed in the first 10% then it hasn't really passed the initial post checks.

Ideally you should look at the MIVR/MCVD to determine exact causes however a few things to check.

- Nic Binding

- Ensure there is no IPV6 configured on the UCCX

- Backup location is valid

- Host files are updated with UCCX node 1,2 and Call Managers

Re: UCCX Backup failed

Hi James,

If backup is still failing after following Hoai's advice; please check to see if a lock has caused an issue with a previous backup. You can open appadmin and go to Tools > Backup and Restore > Status. If the backup has not run for sometime you most likely have a lock. You can do the following

1. Go to 'C:\program files\wfavvid\ClusterData\Default\' folder on CRS server;

2. Rename '' folder to '';

3. Restart nodemanager

Then try a backup.
