Data Loss Prevention
for Business Users (continued) Backup For corporate
mission-critical data this means setting up a structured backup procedure whereby a complete
copy of all files (or sometimes just specific data files) is made, usually on
a tape cartridge, and storing it off-site.
Some procedures call for “incremental backup” of only the changed
files, interspersed with periodic complete backups. This procedure calls for a strict rotation
of clearly labeled tapes that supports a smooth restore procedure should it
be necessary. Particular attention
should be given to the type of backup software used to ensure full
compatibility with your operating system and applications. Restore Any formal backup
routine should be tested by a “trial restore” during the normal course of
operations. If you cannot afford to
risk any downtime with the system in question, try to restore the contents of
that system onto an alternate or spare system. (If your application is mission-critical as
this implies, then you should be maintaining an alternate in any case. See
“redundancy” below.) Redundancy When it comes to
engineering and computers, redundancy is a good thing! When a pilot thinks of a redundant engine,
it is in the context that it will provide power to the aircraft, should the
other engine fail. For the largest
corporations with huge financial resources, redundancy means maintaining an
alternate and remote data center with an up to the minute copy of the
corporate application and data. A
fail-over process will automatically route all data processing activities to
the alternate center during an emergency. If your business is
dependant on its computer system to function, then you need to make an
investment in redundancy as part of your business continuance plan. For example, a small business will often
re-purpose an older server as a workstation.
Can you restore a backup to this computer and use it as the main
server for a short period? A good
contingency plan will identify a work-around or backup for each mission
critical part of your business system. |
