Email Backup or Archival? What’s the Difference?
Most companies will backup your email in one way or another; only some offer “email archival” and that is usually a separate service. On the surface, these seem to be the same thing — providing copies of your data for “just in case”. So, what’s the difference?
A backup refers to a copy of data that may be used to restore the original in the event the latter is lost or damaged beyond repair. It is a safeguard for data that is being used.
Backups are typically:
- Snapshots of what your data looked like at a particular point in time (e.g. when you save a “backup” copy of an important document you are writing once in a while, just in case.)
- Associated with a location. I.e. “on site” backups are located in essentially the same location as the original data. ”Off site” backups are located far away from the originals. It is fast and easy to recover using an “on site” backup; but if the location itself is having issues, both the original and the on site backups could be compromised or destroyed. The off site backups are the fail safe in this case — it is typically slower to recover using them and they are often costlier to maintain; however, if your on site backups are lost, off site is important to have!
“An archive refers to a single or a collection of historical records specifically selected for long-term retention and future reference. It is often data that is no longer actively used.”
Unlike backups, archived email:
- Includes a copy of every message sent or received
- Is not a point in time “snapshot” but a continuously updating history of inbound and outbound messaging
- Cannot be edited or deleted (at least until a certain pre-defined expiration period is met). I.e. archived email must be “tamper proof”
- Cannot be used to restore lost or deleted email folders
- Can be easily searched
- Can be compliant to meet HIPAA, GLBA, and other requirements.
