Data Archiving

Securing Data for Long Term Preservation

Data Archiving unlike backup is designed to protect data for a long time period i.e. 25 years.  This data could relate to a legal case, building or scientific discovery, how it is stored and kept will determine the outcome of that data in 25+ years.  Normally for a business backup always has priority over archiving.  A backup provides short term data protection and helps restore to a point in time normally this could be an hour, day, week or month.  Archiving data requires a different approach for storing data, firstly how do you determine the type of data you want to archive, next where are you going to store it and thirdly where will it be kept?

data archiving

Due to the long term data archive requirements, the people that implement the archive have normally left or retired and so a future proof method is needed.  Copying data from one storage platform to the next over time is the normal method and this is where identifying archive data is problematic as it gets lumped in with the backup.  The backups grow as do the storage costs and data management problems continue as there is no archive just backup.

Storing Long Term Data

Unlike a backup an archive is in place to secure particular types of data, because of this the archive should reside on 2-3 different storage mediums and a copy retained should the original be damaged.

Data Compliance

Any archiving technology should be fully compliant with corporate or government legislation. A data compliant media should be 100% tamper-proof, once information is written it cannot be altered in any way and this should be provable in court.

80% of stored data is inactive after 60 days

Numerous organisations have a huge on-going investment in purchasing data storage systems and this investment is increasing year on year as the demands to store more information increases. After 3-5 years this equipment is then replaced.

With the implementation of a Data Archive solution we can actually extend the life of this investment by moving the data to a secure active archive, thereby freeing up valuable disk space on high performing storage solutions and slowing down the necessary and ongoing investment of more storage space giving a huge ROI benefit. An additional benefit with a tiered data archive is that you
might be able to utilise your existing older storage systems to archive data.

An ideal archiving technology should be:

  1. An open standard that is to say that it is not proprietary or owned by any one organisation.
  2. Have a large installed base of machines that can read this vital information.
  3. Should not be reliant upon proprietary software or hardware.
  4. Can be stored in a normal office environment.
  5. Can easily be duplicated.
  6. Consumes minimal power reading or writing data.
