Following the recent NHS attack, we have fielded a number of enquiries about backup and disaster recovery. The backup model which we’ve followed for some time, and highly recommend, is the 3-2-1 model.
- There should be THREE copies of your data.
- These should exist in TWO different formats.
- ONE copy should be offsite.
The live data used is copy one in format one. The backup to an onsite BDR (Backup and Disaster Recover) server is copy two and is saved in a different format (two). Copying to the other site provides copy three and also fulfills the offsite requirement. The other option for an offsite backup is to copy to an external drive of some kind which a member of staff can take offsite. The bonus of this system is that the offsite is automated and doesn’t require human intervention to work.
This is all very well, but what if you don’t have the luxury of a second office to send your data to? Well that’s where a Datto backup solution comes in, providing you with onsite and offsite backup for servers and data, covered by a monitoring contract with KCS to ensure the backups are running and fix them when they aren’t.
Further to our previous Tech Team Update, The ‘Fire Damaged Business’ that we have been supporting is back up and running and is looking to replace their server and upgrade their business continuity plan with this suggested 3-2-1 model that we are in the midst of putting in place.
They will introduce a new server at their second site which will mimic the backup strategy at their primary sites. These two sites will then send their backups to each other for safe keeping, meaning that if one site is completely lost, they will still retain a copy of the data.
