Heidi is an anlyst at the Enterprise Strategy Group and her thoughts on digital archiving in 2008 are available here.

The main points which interest me in Heidi’s article are:

  • too many companies get archiving mixed up with backups. But these are two wholly distinct concepts
  • archiving to tape is too expensive in terms of staff time taken to retrieve an item, while archiving to primary storage also has cost implications in that you are probably making too many unnecessary backups

Her suggested solution is setting up some sort of automated migration. Manual migration (even manual checking of automated migration, presumably?) will be simply unable to cope with the enormous increase of data expected over the next few years.

There is a cool graph in the article showing how much data is expected to exist by 2010 – 27000 petabytes, probably.
