There are quite some backup types, and terms used when it comes to backups of one's digital content. The following is a collection of the most common types of backup:
1. Local Backup: A local backup is where the storage medium is close at hand. Typically, the storage medium is plugged in directly to the source computer or connected through a local area network to the source.
Examples of Local Backups: Internal hard drive, External hard drive (desktop or portable), Optical drives like CDs, DVDs, and Blue-Ray discs.
Advantages:
a. Offers excellent protection from hard drive failures, virus attacks, accidental deletes and deliberate employee sabotage on the source data, which indeed provides fast backup and restore since the backups stored firmly.
b. Very cheap storage cost, when the right storage medium is in use as external hard drives.
c. Data transfer cost to the storage medium can be negligible or very cheap.
d. There is no need to consign the storage media to third parties as there is full control over the backup storage media and the security of the data on it.
Disadvantages:
Does not offer protection against theft, fire, flood, earthquakes, and other natural disasters as the backup are stored close by to the source. When any of these circumstances damage the origin, there’s a high chance the backup will also destroy.
2. Online Backup: A backup done on a continuous basis to a storage medium that always connected to the source is called an online backup. The term “online” refers to the storage device or equipment connected. Typically the storage medium is located offsite and connected to the backup source by a network or Internet connection. It does not involve human interference to plug in drives and storage media for backups to run. Many commercial data centers now offer this as a subscription service to consumers. The storage data centers located away from the source is backed up, and the data is sent from the source to the storage center securely over the Internet.
Examples of Online Backups: Many commercial service providers are offering this as a subscription service and some market it under the term Remote Backup or Cloud Backup.
Advantages:
a. Online backup offers the best protection against fires, theft and natural disasters, which has a very low risk of data loss from hardware failure.
b. Data loss is very minimal compared to other backups that run less frequently because backups are frequent or continuous.
c. As everything is online, it requires little human or manual interaction after it is set up.
Disadvantages:
a. Online backups are more expensive than local backups.
b. Backups can be slow processing depending on Internet connection speed, and the amount of data backed up, traversing a few days or weeks.
Cloud Backup Strategy:
Cloud backup is a backup where data is backed up to a storage server or tools connected to the source via the Internet. The term “cloud” itself refers to the backup storage equipment being available from the Internet. With the proper authentication, the backup can be accessed securely from anywhere with an internet connection. For instance: Backup services provided by commercial data centers.
Uses:
a. Cloud backup can easily connect and access the backup with just an Internet connection. Data replicates across several storage devices and usually serviced by multiple internet connections, so the system is not at the aid of a single point of failure. When an excellent commercial data center provides the service, assistance is secure, and protection is exceptional.
b. Affordable for small businesses as they do not have unlimited IT budgets. It is essential to use a solution that makes sense and won’t require the customer to acquire a capital expenditure. For a few hundred dollars per year, customers can have all of their data backed up to the cloud.
c. Cloud backup allows the customers to have access to their data anytime and anywhere. As long as there is access to the Internet, through a computer or a smartphone app, all files are readily available. There is no need to have to travel around with a laptop or go back to the office to see that critical file.
d. Cloud backup does not need extra time consignment for the customer. Computer files are backed up to the cloud automatically and continuously, whenever the customer connects to the Internet.
I would like to conclude by saying that, backup strategies with necessary security measures are helpful for any user.
