Quick description of APTrust:
Provides simple, collaboratively designed and built preservation
environment (bit-level with fixity checking) for the digital scholarly
and cultural record (NOW)
Will provide collaboratively developed services for that content
(FUTURE), which may include:
access
format migration
emulation
others TBD
Currently uses Amazon Web Services (as back-end platform only)
Three content
copies in East Coast
data center (three
separate
availability zones)
S3 service
(preservation)
for metadata
and events
Three content copies
in West Coast data
center (three
separate availability
zones) + Fedora copy
Money
● Sustaining Members pay $20,000 per year in dues
○ Engage in governance, strategic direction-setting, development, etc.
○ Get allocation of 10 TB of content (with replication, total of 60 TB)
● University of Virginia provides $400,000 per year toward staffing costs
● Institution wishes to deposit more than 10 TB of content?
○ Pass-through of incremental costs in 5 TB blocks of content
■ previous estimate is $4,250/5 TB/yr, but likely to drop by at
least $1,000 if costs “at scale” continue on current trend
● Approximately $500,000 cash reserve
● Serves as DPN ingest/replicating node (full cost-recovery from DPN)
Current volume (as of October 19)
● 52,000 content objects
● 16 TB (most of which has been ingested in the past month)
● Two institutions anticipate exceeding initial allocation within a month
● More preparing deposits “at scale”
Future
● Much more volume in deposits
● Develop collaborations for additional services
● Develop sophisticated reporting for depositors
● Services for non-members
Challenges
● Drive costs downward to encourage preservation
■ Technical architecture enables interchangeable back-end platforms
● Balance between
■ importance of Trusted Digital Repository certification
■ cost and frequency of TDR audit
● Balance between
■ increased assurance through encryption at rest
■ increased risk through encryption at rest

Diversification
Virginia & Oregon data
centers; future technical
diversity (planned)
At least three dispersed
node data centers;
multiple node-specific
technologies
Content Disposition
Controlled by depositing

Provides possibility for
DPN to “brighten” content
in future
