Backing up¶

Why back up your data ?¶

• Hard disks die
• Portable devices can be lost or broken
• Disasters happen

How to back up data¶

The core principle is that backup copies of data should be stored in a different location to the main copy.

If you delete your local copy of the data then the primary copy will be the original backup... is that copy backed up anywhere ?

• A firesafe
• A network copy
  • An network drive e.g. provided by the institution
  • Internet storage (in the cloud)
  • A data repository - this could be a public thematic / institutional repository for publishing completed research datasets, or an internal repository for archiving datasets during research
• A portable device / portable media which you keep somewhere other than under your desk
