The New Zealand Film Archive collects, preserves, and provides access to over 120,000 film and video titles and 300,000 items. It has over 40 staff members. The Archive stores films at facilities in Wellington and Plimmerton and uses technologies like digitization and data storage on tape and hard drives to preserve and provide access to its collection. Risks to the collection include physical dangers, technological obsolescence, data integrity issues, and over-reliance on single systems or formats. The Archive aims to balance preserving everything with maintaining quality.

25. Technical Risks
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

35. 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 numbers
Compact 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 quality
We can keep everything and have it instantly available
We may lose control of the content and will that devalue it?

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