Re: DM-SIG IT-SIG: costs of backup
Deborah -- Jeff's point about utilizing near-line storage is well taken. This would allow archived images to be accessed relatively quickly without tying up capacity on active servers with material which may not be accessed very frequently, and also would provide some insulation against changes in backup media formats. A related technology which is worth considering is disk-to-disk-to-tape backups, in which files are first collected on a dedicated backup server or near-line storage unit, which can then be backed up to tape or other removable media at suitable intervals. The current version of Veritas Backup Exec (now part of Symantec) is just one of many backup products which utilize this strategy. Your idea about adding backup costs to grant and special project budgets is **definitely** worth pursuing. While it may not be feasible to cover the costs of backups for all eternity, It would be completely reasonably to expect that they be covered for the life of the project. To this end, the budget for any project that will add large amounts of data should at least be expected to cover initial costs for additional backup media and backup drives, as well as additional disk space on whatever server(s) will store the files. The details of how you calculate a reasonable cost will depend on the project and your local setup, so what follows should be regarded as an example rather than an exact formula: * Get the PI of the project to estimate the amount of new data that will be added in the course of the project. She/he may be hesitant to do so, but be firm, because this is information that you will need if you are to plan intelligently for the new load that is about to be added to your system. Add a fudge factor of 10 - 20% to whatever figure the PI comes up with to allow for unanticipated storage needs. * Armed with this total, figure out how many tapes/CDs/DVDs would be required to run your normal backup schedule for at least one year, using all new media. Assume a compression ratio of 1:1 (i.e.: no compression) in doing this calculation. * If your ability to get backups done in a reasonable length of time is already stretched, add in the cost of one or more additional backup drives (and, if needed, other backup-related hardware). * Add in any extra hard drives or other hardware that will be required to accommodate the new data. * Calculate what all of this would cost at today's prices. In the case of backup media, don't automatically assume that the newer, higher capacity formats are the most economical choice. Depending on the total amount of data to be backed up and your normal backup schedule, the newer formats may or may not be a better deal. For a graphic example of this, spend some time experimenting with Quantum's Tape Product Advisor tool, a link to which can be found near the top of the following page: http://www.quantum.com/Products/TapeDrives/Index.aspx Although the results depicted there are only approximations, changing the variables and seeing how the theoretically "perfect" number of drives and tapes changes can be instructive.

Fwd: Orphan Works Testimony
>From Amalyah Keshet, Israel Museum: Orphan Works Testimony, House Judiciary Intellectual Property Subcommittee March 8 Many thanks to Diane Zorich for bringing this important opportunity for action to the attention of MCN President Marla Misunas, and to the MCN Board of Directors for signing MCN on as a supporter. "Maria Pallante-Hyun, Associate General Counsel and Director of Licensing at the Solomon R. Guggenheim Foundation/Guggenheim Museum (and a frequent MCN speaker at IP SIG sessions at MCN conferences), will be presenting important testimony on behalf of the cultural heritage community at the House Judiciary Intellectual Property Subcommittee hearing on Orphan Works (i.e., works whose copyright owner cannot be located). The hearing is slated for Wednesday, March 8th, at 2:00 PM on Capital Hill. Maria and attorneys from many other museums have been spearheading the orphan works initiative on behalf of cultural heritage organizations. This opportunity to testify in front of the House Judiciary IP Subcommittee to lay out the concerns that cultural organizations have with orphan works legislation is very important. Organizations "signing on" to the testimony include AAM, ALA, ARTStor, JSTOR and CAA. We want to emphasize that a strong showing of consensus for Maria's testimony is critically important for achieving an Orphan Works legislative solution that best meets all of our needs." "The issue of orphan works is of great importance to MCN's constituency. Our members' attempts to make museum collections and archival information accessible to the public are often thwarted by their inability to locate copyright owners. They frequently have to keep materials from public programming because copyright ownership cannot be determined and their institutions cannot assume the risks of potential infringements. We believe Ms. Pallante-Hyun's testimony crystalizes our concerns and outlines a positive and equitable way of addressing the orphan works issue. Implementing her suggestions would result in an outpouring of previously "off-limits" materials, resulting in untold research and educational opportunities."
