Every time manageiq pod is rescheduled a backup is performed for all metadata (for recovery purposes). Currently it backs up all the content of the PV (which include log files). Logfiles should be excluded for 2 reasons: 1 - it may create a timeout on pod execution (and reschedule) when the log files are big and it takes too long to back them up 2 - it is a big waste of disk space

Verified. I rescheduled the cfme pod, checked the storage, no backup was found.
