If you are interested in how the National Archives of Australia handles digital archiving then there is information (primarily software & format focused) here: http://www.naa.gov.au/records-management/preserve/e-preservation/at-NAA/index.aspx But they do say on one of the pages below that: # When selecting the hardware and systems for its digital # preservation prototype, the National Archives avoided # relying on any single vendor or technology. In so doing, # we have enhanced our ability to deal with hardware # obsolescence. Technology is our enabler, but we don't want # it to be our driver. Conceptually, the digital repository # is one system, but it comprises two independent systems # running simultaneously, with different operating systems # and hardware. # # By operating with redundancy, we are future-proofing our # system. In the event of an operational flaw in any one # operating system, disk technology or vendor, an alternative # is available, so the risk to data is lower. - -- Christopher Samuel - Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: sam...@unimelb.edu.au Phone: +61 (0)3 903 55545 http://www.vlsci.unimelb.edu.au/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk4uU/cACgkQO2KABBYQAh+t0gCfWKLfIv++/x7iK1XLVGgpDIpM QkkAoIbCKLB2uL4U0QimO1l7WYPOQ5gK =nC+k -----END PGP SIGNATURE----- _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
