Moved away from DVDs and external drivers (except occasionally for ingest) and work directly on server (IT supported
Network File System) for all steps in the process. Storage needs: so far, have depended on the recommendations from
DLI programmers and systems staff.
Needs are estimated based on known incoming materials in the short term, ideally several weeks/months in advance.
We will gradually add TB of storage space as needed.
Not applicable at this time. Pending.
Our storage projections account for our born-digital and locally digitized materials and are based on the fact that we
will have a number of file types which, both in their native and any normalized formats, are quite large: for example,
uncompressed tiff files and video files, and large datasets. Costs are determined by library and central IT.
Our units look at recent activity requiring digital storage, and at future projects and goals to estimate our upcoming
storage needs.
Past years’ growth and projected new acquisitions of born-digital collections.
Planned digitization activities or acquisitions of born-digital material are planned for the fiscal year. Storage amounts
required to accommodate that digital content are devised based on average file size for a particular type of record. Costs
for this storage are estimated based on current market value, usually at the TB level.
Planning for digital storage needs and costs is the responsibility of the library systems department and the Associate
University Librarian, Digital & Discovery Services, with consultations with department heads on their storage needs for
ongoing activities and special projects.
Project by project, case by case.
Read research and follow trends. (Our recent move to Cloud storage for example. Once method is tested by other
institutions and proven to be trust-worthy.)
Still developing.
The Digital Data Curator and Director of IIS monitor storage utilization and recommend purchases for grants and for
annual purchase based on the types of materials currently stored and anticipated storage needs for project in planning
or currently under way.
The library is working on a plan to estimate future storage needs now. Currently it is just allocated on an as-needed
The recent inventory is a first step. In addition to the inventory curators have been asked to estimate growth rates.
Library IT is investigating storage options including the cloud and cost models for storage.
This is a process receiving on-going development. Currently, space needs are estimated given past collecting volume + a
20% inflator and any known collections we anticipate receiving. Costs are estimated by the library IT staff based on the
cost for the storage they lease from the university’s Office of Information Technology.
Track historical usage and growth contrasting the resultant data with projections/requests previously provided
from librarians. This provides a delta of growth not contained in a long-term plan. Track usage from new initiatives.
Categorize the data by type; identifying growth areas. An example of historical usage follows: in November of 1999,
the fileserver had 5 GB of disk storage available for all library employees. In 2000, there was approximately 30 GB of
storage made available. In April of last year we were backing up around 10 TB of data. Currently we back up 18 TB of
data. This data is “information” versus server images, etc. An example of a new initiative: The Dean has expressed a
