Obsolescence - hardware & software have a finite lifetime
Data Integrity - latent errors, ingest errors, transfer errors
Single Point Loss - single copy vulnerable to machine error, human error or natural disaster
Mono Culture - singular technologies can suffer
Compression - mathematically lossless, perceptually lossless, lossy compression
Technical Risks

The Automated Archive no more boring tasks in your paperless office
Digital deposit, accessioning and cataloguing through metadata and crowd sourcing
But getting everything digitised is hard on humans
The Distributed Archive
safety in numbersCompact storage and many copies means less risk of loss
More reliant on complex technology and material can still burn and drown
The Everything for Everyone Archive
quantity vs qualityWe can keep everything and have it instantly available
We may lose control of the content and will that devalue it?

The Digital Archive promises a bright future
We just have to keep up with it
