Digital records become inaccessible or destroyed if neglected.
Personal digital archiving is not just about saving files – it's about making sure they stay accessible in the future, as well as planning how new digital records will be created, stored, and preserved.
Common threats to digital records
Natural disasters and inappropriate conditions
Like physical records, digital records can be damaged through floods, fires, storms or human activity.
Natural disasters can damage or destroy the computers or drives that the digital records are stored on. This is why it is good to have more than one copy of the archive kept in different locations.
Cloud based storage is also vulnerable to natural disasters, as it is a physical digital server.
Inappropriate conditions are another danger for the storing of records. Extreme temperatures, humidity, pests or magnetic fields can cause digital records to become corrupted, or storage hardware to become damaged.
Human damage or theft
Human activity can result in the physical damage of the storage media through:
- mishandling
- theft
- being misplaced.
Another type of human caused disaster might be a security breach or a virus. These can result in records being destroyed, stolen or corrupted.
Hardware and software obsolescence
Hardware and software become increasingly difficult to access over time. These access risks can take many forms.
- The hardware technology used to store and access records may stop being widely available. Many computer systems no longer have CD or DVD drives, and it is increasingly difficult to find device readers for floppy disks.
- File formats can become inaccessible over time. This can occur due to software updates which fail to support previous file formats. The Library of Congress maintains a list of recommended file formats.
- Software no longer being accessible. Digital records need to be read using the right software in a compatible operating system. Some file formats, such as JPG, can be opened in multiple software programs. Other formats require specific software to render the file. Even when you have the right software, not all modern operating systems will support it.
Poor planning
As people create more digital records, a common problem is a lack of organisation and planning. Without good planning records are easily lost, damaged or unable to be opened. Much of this guide is about how to build good planning into how you keep your digital records.
Good planning includes:
- considering what time, skills and resources you have
- a consistent and repeatable plan
- deciding who is responsible for doing what tasks,
- what to do if the primary archivist dies i.e. a digital will
- selecting only the most valuable records
- cataloguing records so they can be easily found and opened
- consistent and understandable naming
- A consistent and understandable folder structure
- updating software and storage
- considering what software to use when creating records
Corruption
Corruption is when a file is altered or damaged, making it unusable.
Digital records can become corrupted in a number of different ways, such as:
- extreme temperature or magnetism affecting hardware,
- malware and viruses,
- copying errors,
- file aging,
- during copying or simply through age.
Without checking you may not know if your record has become corrupted. It is important to have backups of all files. Once a file becomes corrupted it can be very hard to repair, so it is easier to replace it with an uncorrupted copy.
