#Checks
# Checks to make sure the API is functional as JB likes to hang...
# Checks to make sure all 3 notification profiles are there and not disabled.
# Checks to make sure there hasn't been 3 failures in the past 14 log entries (should be 14 days.. unless it's being ran manually)
# Checks to make sure there is a JB Destination called 'Cloud Backup' and it's enabled.
# Checks to make sure there is a JB Backup Job called 'API Backup Job' and it's enabled.
# Update - BFENG-2704 - fix while touch file creation is failed during quota full.
