Hello lamw,
i checked the line and it isn't the same issue.
If i remark the following line(like the thread "http://communities.vmware.com/message/2188924#2188924"), the Backup runs without error.
"elif [[ -f "${VMX_PATH}" ]] && [[ ! -z "${VMX_PATH}" ]]; then"
If ALLOW_VMS_WITH_SNAPSHOTS_TO_BE_BACKEDUP is enabled, the script delete all Snapshots.
Is this a normal effect, if ALLOW_VMS_WITH_SNAPSHOTS_TO_BE_BACKEDUP is enabled?
BTW: Great script
