-# What is the particular preservation goal or challenge you need to accomplish? (for example, re-use, public access, internal access, legal mandate, etc.)
+These responses pertain to Harvard's Digital Repository Service (DRS). See [http://hul.harvard.edu/ois/systems/drs/].
-# What large scale storage or cloud technologies are you using to meet that challenge? Further, why did you choose these particular technologies?
-# Specifically, what kind of materials are you preserving (text, data sets, images, moving images, web pages, etc.)
+'''1. What is the particular preservation goal or challenge you need to accomplish? (for example, re-use, public access, internal access, legal mandate, etc.)'''
-# How big is your collection? (In terms of number of objects and storage space required)
-# What are your performance requirements? Further, why are these your particular requirements?
+The DRS provides professionally managed services to ensure the usability of stored digital objects over time. The DRS is both a preservation and an access repository. In other words, its obligations include assurances that stored digital content will remain both viable and accessible into the indefinite future despite a constantly changing technological environment. All objects managed in the DRS will receive the highest level of preservation service consistent with the object's characteristics and the current technical capabilities of the DRS and its staff.
-# What storage media have you elected to use? (Disk, Tape, etc) Further, why did you choose these particular media?
-# What do you think the key advantages of the system you use?
+'''2. What large scale storage or cloud technologies are you using to meet that challenge? Further, why did you choose these particular technologies?'''
-# What do you think are the key problems or disadvantages your system present?
-# What important principles informed your decision about the particular tool or service you chose to use?
+We are currently using SUN SAM/QFS Storage Archive Manager 4.6, Dual Sun T2000 Solaris SAM servers (redundant servers at site 1, disaster recovery failover at site 2), EMC CLARiiON disk storage arrays (a CX3-40 at site 1, CX3-80 at site 2) and a StorageTek SL500 tape library.
-# How frequently do you migrate from one system to another? Further, what is it that prompts you to make these migrations?
-# What characteristics of the storage system(s) you use do you feel are particularly well-suited to long-term digital preservation? (High levels of redundancy/resiliency, internal checksumming capabilities, automated tape refresh, etc)
+'''3. Specifically, what kind of materials are you preserving (text, data sets, images, moving images, web pages, etc.)'''
-# What functionality or processes have you developed to augment your storage systems in order to meet preservation goals? (Periodic checksum validation, limited human access or novel use of permissions schemes)
-# Are there tough requirements for digital preservation, e.g. TRAC certification, that you wish were more readily handled by your storage system?
+We are preserving audio, web harvests, page-turned content (books, manuscripts, etc.), documents, still images, biomedical images, target images, text, color profiles, and related documentation and rights objects. By next year we will also be preserving email messages and attachments.
