Re: arsclist Digital knowledge preservation

["John Spencer" <jspencer@xxxxxxxxx>]

I would point out that one of the biggest issues regarding archival storage
is the usage of "Enterprise-class" storage media that is used by large
corporations (i.e., Fortune 500, etc.) - and that basically revolves around
LTO or SDLT (and perhaps AIT).  It should also be assumed that the data will
have to be migrated on a regular basis to ensure the ability to retrieve it.
Any "consumer" format, IMHO, is a crap-shoot with respect to availability.
We in the audio industry get the scraps from the corporate computing
industry, and archival storage will have to follow these conventions.
