UK DATA ARCHIVE
OVERVIEW
LOOKING AFTER RESEARCH DATA FOR THE LONGER-TERM AND PROTECTING THEM FROM UNWANTED LOSS REQUIRES HAVING GOOD STRATEGIES IN PLACE FOR SECURELY STORING, BACKING-UP, TRANSMITTING, AND DISPOSING OF DATA. COLLABORATIVE RESEARCH BRINGS CHALLENGES FOR THE SHARED STORAGE OF, AND ACCESS TO, DATA.
AREAS OF COVERAGE• Making back-ups • Data storage • Data security • Data transmission and encryption• File sharing and collaborative environments• Data disposal

FIELDWORK FROM HELL
“I’m sorry but we had to blow up your laptop.”
“What….all my client case notes and testimony, writing, pictures, music and applications. Years of work. NO!!!! What?? Are you insane?? What were you thinking? THAT’S ALL MY WORK!?”

BACKING-UP DATA
• why do back-ups? Risk of loss and change - would your data survive a disaster?
• protect against: software failure, hardware failure, malicious attack, natural disasters
• back-ups are additional copies that can be used to restore originals
• it’s not backed-up unless backed-up with a strategy
……………………………………………………………………………………………………………………………….……………………………..

BACK-UP STRATEGY
• consider:• what’s backed-up? - all, some, just the bits you change?• where? - original copy, external local and remote copies• what media? - CD, DVD, external hard drive, tape, etc.• how often? – assess frequency and automate the process• for how long is it kept?• verify and recover - never assume, regularly test a restore
• backing-up need not be expensive• 1Tb external drives are around £50, with back-up software

DATA STORAGE
• all digital media are fallible• at any moment – but there can be warning signs
• file formats and physical storage media ultimately become obsolete • optical (CD, DVD) and magnetic media (hard drive, tapes) degrade• never assume the format will be around for ever
• best practice:• use data formats with long-term availability• storage strategy - at least two different forms of storage and locations• maintain original copy, external local copy and external remote copy• copy data files to new media two to five years after first created • check data integrity of stored data files regularly (checksum)• know your personal/institutional back-up strategy• know data retention policies that apply: funder, publisher, home institution• what to protect? not only data, and not only digital

DATA SECURITY
• protect data from unauthorised access, use, change, disclosure and destruction
• personal data need more protection – always keep separate
• control access to computers • passwords• anti-virus and firewall protection, power surge protection• networked vs non-networked PCs• all devices: desktops, laptops, memory sticks, mobile devices• all locations: work, home, travel• restrict access to sensitive materials e.g. consent forms, patient
records
• proper disposal of equipment (and data)• even reformatting the hard drive is not sufficient
• control physical access to buildings, rooms, cabinets
• but beware of ‘requirements’ to destroy data

ENCRYPTION
• always encrypt personal or sensitive data
• encrypt anything you would not send on a postcard• for moving files e.g. transcripts• for storing files e.g. shared areas, mobile devices
• basic principles• use an algorithm to transform information (A=1)• need a ‘key’ to decrypt
• many free softwares that are easy to use• Safehouse• Truecrypt• Axcrypt
• these products:• encrypt hard drives, partitions, files and folders • encrypt portable storage devices such as USB flash drives

DATA DESTRUCTION
When you delete data and documentation from a hard drive: it is probably not gone
• files need to be overwritten to ensure they are irretrievably deleted:• BCWipe - uses ‘military-grade procedures to surgically remove all
traces of any file’
• Axcrypt
• if in doubt, physically destroy the drive using an approved secure destruction facility
• physically destroy portable media, as you would
shred paper

FILE SHARING & COLLABORATIVE ENVIRONMENTS
Sharing data between researchers and teams
• too often email attachments
• Yousendit, Dropbox – consider if appropriate as services can be hosted outside the EU
• open source repository software for data, e.g. Fedora and DSpace - early days
• Virtual Research Environments• MS SharePoint• Sakai
• file transfer protocol (ftp)
• physical media
