Working Files

The vSphere Plugin creates special files in the working directory. These files are needed to use the Changed Block Tracking (CBT) VMware feature. To clean up the vSphere Plugin working directory, you can schedule the vsphere-ctl command as:

# /opt/bacula/bin/vsphere-ctl clean 30

It will remove files and directories after a period of 30 days. This period should correspond at the minimum to the Full interval period plus additional days for safety reasons. During the backup, if the vSphere Plugin is not able to find working files created during the last Backup, the vSphere Plugin will create the necessary directories and upgrade the backup job to a Full backup of all disks.
