For any person who has his own business, the question of selecting either one of a data backup solution or data replication tends to creep up. There is no one answer to this question as both options have their own advantages as well as disadvantages. So in the world of backups vs replication, what exactly is the difference and what should you choose for you and/or your business?
In order to determine which option you should go with, you should know the difference between business continuity and disaster recovery.
Disaster recovery refers to the process that you use after the occurrence of a disruptive event in order to resume your business. The disruptive event can range from major disasters such as hurricanes and earthquake to mild events such as a computer virus resulting in the software malfunctioning.
What it Means for Business Continuity
Business continuity refers to the procedures that a business implements in order to ensure that the essential functions of a business continue working during and after any disaster that may strike. This is to ensure that business is resumed smoothly as soon as possible while emergency services are provided at all times.
If your business suffers from a severe natural disaster such as a hurricane, using a data replication strategy will ensure that you can restore any lost data from the replicate storage, which in turn will allow your business to operate smoothly without any hindrances whatsoever.
What About Replication?
If a user accidentally deletes something from the main storage, the deletion will also occur in the secondary and tertiary storages as well. This means that if a file is corrupted, then replication storage will not be sufficient for its recovery.
With most of the restores resulting from corruption and human error instead of data loss, replication storage cannot be relied upon for the complete protection of the data of your business.
If you employ a backup system, then you can simply go back to the point in time when the deletion or corruption was yet to occur, thereby ensuring its prevention. While replication can improve your storage capabilities, if you want proper protection of your data, then a backup system is a must.
Of course, employing both solutions will significantly improve your data protection, it can be a bit expensive and for those who are on a budget, it is a good idea to use a service that makes use of a backup platform in order to create a replica of your entire data.
