Do you know what is the difference between backup and disaster recovery? Did you think before about those terms before?
All of us hear about backup, there is always a reminder in our life, you see it in smartphone and with software tips, but disaster recovery is not listed in our terms list it’s not in our dictionary.
Most of small business owners mostly don’t know the difference between backup and disaster recovery, today’s blog, is lowdown of backup vs. disaster recovery, to know the deference.
Backup, what is it?
Let’s start with basics, what is backup? In summary, backup is copying data to storage. This can be through DVD, SAN storage or by means of remotely storage "Cloud".
It is very important to have a backup solution in place. You will protect your data loss in case of employee accidents (delete data), theft (Laptop lost) and technical problems (Server crash); with backup you can restore your data easily.
Disaster Recovery, What is it?
Disaster recovery is similar to backup but disaster recovery used for larger instances. A full image of your servers and disks are mirrored. The image increases the probability to restore your systems faster than re-installing OS and restoring data.
Now read the term “Disaster” does this term make sense to you, don’t get caught up on this term and believe it has to be a major accident. A disaster can be your networks equipment’s and servers are crashes and all of the organization employees no longer work for one day or more. With disaster recovery plan, the organization employees can continue to work using the mirrored systems and servers and IT people work on fixing the problem at main site “Original systems place” while all of business employees are working on the mirrored systems.
Backup is similar to disaster recovery, but disaster recovery is more wider than backup and disaster recovery plan contains backup plans, backup is needed to restore data when case of loss of original data, data in disaster recovery is not needed to restore, employees are moved to work on the mirrored systems in case of data loss or system crash in main data location.
