Storage
and Backups: Key Insights
§Determine what data needs to be stored and for how
long
□Once
the system is out of test mode, is there any need to retain all that information?
□Most
industries do not have hard-rule on how this should be done
□In
aviation industry, data are typically kept for only a brief period of time
before being discarded. If incident occurs, data are spooled off for
review before being destroyed
§Frequent backups and storage off site is typical
□Google
(Search Engines) does real‐time
streaming backups across multiple data centers in order to ensure that searches are always
available
§Perform preventative maintenance regularly
§Consider allowing a third party to handle data storage
needs
□Cost
of keeping all traffic data may be prohibitive for the government,
but profitable for a third
party
