What are the four main types of data backup?
Local backup of server without drive rotation
The simplest form of business data backup where a physical device is in your office without additional drives. Local backup of a server without drive rotation has the advantages of a quick recovery of data in the event of single file loss or entire server being encrypted by Malware. However, if you suffer a catastrophic event that destroys the server and local backup such as fire or flood, all your data on this device will become compromised.
Offsite backup via hardware
Offsite backup via hardware works in the same way as local backup of a server. However, instead of storing your businesses data onsite, physical device in your office with removable drives/tapes that can be stored offsite.
Should a disaster happen within your organisation, having an offsite backup via hardware means that your business data can be recovered quickly via drives and tapes that have been stored offsite.
This will take some time to manually perform daily backups and as this process isn’t automatic, there is a risk that staff can forget to manually backup data which could mean there is no backup over a period of days. You must also ensure that any backup devices taken off site are encrypted in case of theft.
Offsite backup to the Cloud only
Instead of keeping all of your business data in the office, an offsite backup to the Cloud is where all of the data is sent to a remote Cloud-based datacentre – there is no physical onsite backup facility enabled.
Backups of your data to Cloud can be conducted automatically at intervals. The pathway the data takes from your business to the datacentre is encrypted and secure. Then, the data itself in the datacentre is secure in a heavily fortified Cloud server.
Data is automatically backed up at your scheduled time with no manual intervention, and in the event of full Disaster Recovery in case of catastrophic event in the office. We use backup tools such as Altaro, one of the leading backup suppliers and store the data in Microsoft Azure, which is highly secure. However, there are several options available in regards to Cloud backup depending on your needs.
Combined local backup and cloud offsite backup
A combination of local backup and Cloud offsite backup means that your organisation is backed up by a physical device in your office and also has the implementation of a Cloud backup service.
Should a disaster happen to the backup that’s local to your office, the Cloud backup will be there to keep your data secure and the proximity of data is able to be restored quickly to keep your business operations running smoothly. Full disaster recovery protection from the cloud backup in the event of a catastrophic incident and quick recovery from local backup in case of accidental deletion or server being encrypted by Malware.
Your business can begin to construct your business disaster recovery plan by evaluating the core elements of your system setup and determining the importance of each one. You can then easily establish the likely implications should an element of your IT Infrastructure failing.
Instead of writing a large and complicated document, write your disaster recovery plan in the form of an easy to understand flow chart for each element so the core team know what to do in the event of a disaster situation which will save valuable time and reduce stress at a time of crisis.
