Tales Of Lost Data

The Lost Laptop Problem¶

• 2010 Ponemon Institute report for Intel re. US laptops
  • On average, 2.3% of laptops assigned to employees are lost each year
  • In education & research that rises to 3.7%, with 10.8% of laptops being lost before the end of their useful life
    • ~3 years i.e. within 1 PhD of allocation!
  • 75% lost outside the workplace
• Very similar results from 2011 European report!

Reliability¶

Laptop Reliability¶

• 2011 PC World Laptop Reliability Survey from 63,000 readers:
  • 22.6% had signifcant problems during the product's lifetime
  • Of which...
    • 19% had OS problems ~1 in 25 of all laptops
    • 18% had HDD problems ~1 in 25 of all laptops
    • 10% PSU problems ~1 in 50 of all laptops

Hard Disk Failures¶

• Failure Trends In A Large Disk Drive Population
  • Usenix conference on File and Storage Technologies 2007 (FAST '07)
  • Eduardo Pinheiro & Wolf-Dietrich Weber, Google Inc.
• Data collected from over 100,000 disk drives at Google
• As part of repairs procedures:
  • ~13% of disk drives replaced over 3 years
  • ~20% of disk drives replaced over 4 years

Archiving Data¶

BBC Domesday Project¶

1986 Project to do a modern-day Domesday book (early crowd-sourcing)

• Used “BBC Master” computers with data on laserdisc
• Collected 147,819 pages of text and 23,225 photos
• Media expiring and obsolete technology put the data at risk!

Domesday Reloaded (2011)

• Required emulation of software
• Images restored from original masters
• http://www.bbc.co.uk/history/domesday

To allow long-term access to data

• Don't use obscure formats!
• Don't use obscure media!
• Don't rely on technology being available!
• Do keep original source material!
