Came across an article today. Nothing new for those in the digital preservation trenches, but a good reminder or wake up call.
from the article:
…digital preservation is now moving up the corporate agenda as senior executive stakeholders realize that storage on its own is not enough. As more “born digital” content is produced every day, requirements get more complex, and the need for organization-wide digital preservation strategies becomes greater.
The article mentions the “tipping-point” for accessing digital data is around 10 years.
I would suggest an evaluation of the state of your digital media/data every two to three years, if it has become inaccessible in 10 years then 10 years is too long to wait.
