usefulness of tape media. Additionally, magnetic fields can act as a

degausser and erase or corrupt data on the tape. With this in mind,
tapes should not be exposed to magnetic fields that can come from
sources such as elevator motors and some printers. Here are some
useful guidelines for managing tape media:

Keep new media in its original sealed packaging until it’s needed to
protect it from dust and dirt.

When opening a media package, take extra caution not to damage
the media in any way. This includes avoiding sharp objects and not
twisting or flexing the media.

Avoid exposing the media to temperature extremes; it shouldn’t be
stored close to heaters, radiators, air conditioners, or other sources
of extreme temperatures.

Do not use media that has been damaged, exposed to abnormal
levels of dust and dirt, or dropped.

Media should be transported from one site to another in a
temperature-controlled vehicle.

Media should be protected from exposure to the outside
environment; avoid sunlight, moisture, humidity, heat, and cold. It
should be acclimated for 24 hours before use.

Appropriate security should be maintained over media from the
point of departure from the backup device to the secured offsite
storage facility. Media is vulnerable to damage and theft at any
point during transportation.

Appropriate security should be maintained over media throughout

the lifetime of the media based on the classification level of data on
the media.

Consider encrypting backups to prevent unauthorized disclosure of
data if the backup tapes are lost or stolen.
