For any computer data, along with EMF shielded containers, other alternatives should be
considered. Off-site as well as on-site backup facilities should be examined. I advise that
onsite backups and offsite backups, as well as storing backups in a shielded safe be
employed. Also making CD-ROMs of data, particularly any imaging data, is good
protection, so that if the magnetic media ever gets corrupt there will be one form of a
non-erasable copy of the data. CD-ROM recorder / rewriteable drives can be purchased
for less than $300. Media to store 650MB is about 1.50 a piece. EMP can cause power
surges which can bypass any shielding you have in place if plugged into the wall. Battery
backups are vital. Hardware problems can be cut in half all components (except for
printers) have battery backups. They are much cheaper to replace, if blown, than the
computers they keep up.
