Data Storage Security – Backup Plans for Cloud Storage
Listen to this article
Data is the most important thing in the 21st century. It is the propellant helping science and technology bring novel engineering marvels. It is the force behind the spectacular growth of businesses in modern times. It helps enterprises identify the root cause of a problem and predicts the possible solutions as well.
Today, every industry depends immensely upon data and this is the reason they record all sorts of data that can be fruitful to them. Be it related to operations, sales, human resources, marketing, or product, they want to store their data at a safe and secure location.
“Data storage is the collective technologies and methods for recording and retaining digital information on computer components, electromagnetic, silicon-based, or optical storage media.”
Various Data Storage Methods
It is extremely important for an organization to identify the correct method for storing their data. Following are some of the prevalent data storage techniques:
Data is stored in a private data center, having data servers that are owned and managed by the company.
A private data center owned and managed by a third party, available for businesses on a rental basis.
Private Cloud Storage
A virtual data storage solution is known for its greater security through data encryption protocols.
Public Cloud Storage
Another virtual data center offering great versatility due to its superior scalability and computing power.
Data Storage Security
Protecting data and storage resources is of utmost importance for any organization. A breach of security means losing business-critical data that can lead to huge capital loss and even business loss in the worst scenario.
Data Storage Security ensures the safety of data as well as storage devices, minimizing the risk of data theft, destruction, corruption, unauthorized access, or data tampering.
Following are some of the major reasons why data storage security is important:
➢ Safeguarding a valuable asset
An organization invests a great deal of time, money, and other resources for capturing and maintaining critical data, which if lost, can immensely hamper the growth of the organization.
➢ For developing and maintaining brand loyalty amongst customers
It takes great time and effort for a company to gain its customers’ trust and a security breach is all it takes to ruin that.
➢ Curtailing monetary losses and unnecessary expenses
Data theft or leak leads to the loss of important and confidential data which puts a great financial burden on an organization.
Cloud Storage and Data Security
With benefits like on-demand access, easier scalability options, cost-effective computing solutions, etcetera, enterprises are embracing the cloud at a tremendous pace. Cloud-based storage solutions offer great convenience compared to traditional on-premises or off-premises data storage centers. There are numerous cloud service providers offering all public, private, and hybrid cloud storage as well as other cloud-based services that are known for their enhanced security.
The following are the key measures adopted by various cloud service providers to ensure data security:
● Firewall Protection
Both incoming and outgoing data packets are inspected as per the defined security protocols. Advanced firewalls act as a barrier between the traveling traffic and internal networks and block malicious entries like that of hackers or viruses.
● Data Encryption
Data Encryption is a technique that scrambles the readable data in order to keep it safe from unauthorized access. Encrypted data is worthless for anyone who does not have the decryption key.
● Event Logging
Event logs are used to capture network actions. The data in the logs help security analysts predict and prevent data breaches and security threats.
● Multi-Factor Authentication
Multi-Factor Authentication tool that offers an additional layer of security that stops cyber-attackers and hackers from gaining access to employee credentials having entry permissions. Often, a one time password or an access code is used to provide that extra layer of security after logging in with a password.
● Physical Security
Certified cloud data centers incorporate fingerprint locks, armed security personnel, and 24/7 monitoring. A combination of various physical security methods is used to make these data centers far more secure than on-site data storage centers.
Backup Plans for Cloud Storage
Hackers and account hijackers always have an eye on your data and while taking correct security measures safeguard your data from theft or leak, backups help you recover in an event of data loss or corruption. Data backup is one of the significant components of an organization’s disaster recovery as well as a business continuity plan.
Cloud backup is a remote, online backup service where a copy of physical files or database is sent to an off-site, secondary location (the cloud). Online backups are commonplace these days and are regularly used by all enterprises, irrespective of their size.
The following are a few features of online backups:
- They are generally hosted by third-party service providers
- Users are charged on an annual or monthly subscription basis
- The subscription charges are based upon the storage used, number of users, data transmission bandwidth, and number of servers etcetera
Listed below are the basic steps involved in cloud backup and access:
- File Selection – Files, applications, and folders are chosen for backup. These could be new or updated files or applications.
- Encryption – The designated files are encrypted and then sent to the cloud for backup.
- Backup Method Selection – A user or organization can select any of the private cloud, public cloud, or cloud-to-cloud (C2C) backup options.
- Access – In the event of a catastrophe, the files are readily available for access and recovery.
There are various approaches to online or cloud backup. Organizations can choose the one that best fits into their data privacy and protection process. Following are the various plans for a cloud backup:
Direct backup to the public cloud
In this approach, an organization makes use of its own backup application that creates a copy of its data and transfers it to the public cloud. The cloud storage service providers like Microsoft Azure or AWS define the destination and safekeeping of the data. As the backup software is company-owned, it must be capable enough to interface with the cloud.
Cloud-to-Cloud (C2C) backup
C2C backup is a method where data stored on one cloud is backed-up on another cloud. Also known as a Software as a service (SaaS) backup, it is growing in popularity day by day. This cloud backup strategy keeps the duplicate data in a different cloud and hence adds an additional layer of security. The C2C backup service also hosts the software handling the data backup process.
Backup as a Service (BaaS)
It is a method in which a third-party, cloud backup service vendor backs-up the data to a remote cloud-based repository. The backup software may be provided by the backup service vendor or it may use some other commercial backup tools. The greatest advantage of using this backup approach is that the BaaS provider manages everything from data transfer to integrity checks.
Online backup systems
Online backup systems are hardware machines having backup tools along with storage capacity and backup server. They are all-in-one appliances, used as plug-and-play data backup options. These machines store the most recent backups on local storage in order to save time and challenging costs while recovering the data. Vendors such as Dell EMC, Asigra, Rubrik, and Quantum etcetera offer these seamless, ready-to-use data backup systems.
In this world of cloud computing, it is very important for an organization to implement a cloud data backup strategy so as to remain immune to the ever-existing data threats and other such catastrophic events.
