How to protect data from radiation and strong magnetic field?

  1. Jun 30, 2012 #1
    I keep my files using HDD, can my files still be retrieved under radiation and strong magnetic field?

    Will it be better if I copy them into DVD disks?

    Does anyone have any suggestions?
    Thanks in advance for any suggestions

    Strong magnetic fields at the disk can erase the data - DVDs are better, as they do not rely on magnetization.
    Radiation: Probably depends on the type of radiation.

    If you expect significant radiation or strong magnetic fields somewhere (why?), what about an external backup?
