On our blog yesterday, we talked about the advantages of on-premise backup over offsite backup. Today, let us discuss the superiority of cloud backup over offsite backup.
Let us say you have an onsite backup server and would like to make a Offsite Data Copy. Your choices are:
- Cloud Sever (in our case, Amazon Cloud).
- Offsite Sever.
While the cloud backup and offsite backup servers have many similarities when it comes to Offsite Data Transfer.
There are also many other advantages to cloud backup:
- An offsite server requires expenses for hardware purchase, server construction and maintenance while cloud backup costs only for storage size.
- The security measures on offsite backups can be compromised either at storage level or in transit. It costs quite a bit to provide military grade protection to backups. In contrast, Amazon Cloud’s world-class, high level security, stores data in encrypted format with AES-256 encryption. For more information visit http://aws.amazon.com/security/.
- An offsite backup server is vulnerable to disaster and the probability of data loss from a natural calamity is high in offsite backups. Amazon Cloud provides option to have mirror copies of a backup data in various locations which assures high data availability even during a natural calamity.
- Business continuity is promised by Amazon which is not a guarantee in offsite backups. The latter is therefore not a recommended practice for storing business critical data.
Hybrid backups are getting very popular these days where an on-premise server is setup for backups which have Offsite Data Copy on cloud server. A hybrid backup model is advised for businesses that require a more cost efficient and secure backup model.
There is nothing quite like learning first-hand the advantages of on-premise backup.
