CLOUD BACKUP & DISASTER RECOVERY
The purpose of backup is to create a minimum one copy of all data so that a particular file or application may be restored after data is lost, corrupted, deleted or a disaster strikes. Organizing storage space and managing the backup process can be a complicated undertaking. A data repository model may be used to provide structure to the storage. Nowadays, there are many different types of data storage devices that are useful for making backups.
Before data are sent to storage locations, you should consider the following:
• What data (files and folders) to backup.
• What compression method to use.
• How often to run backup.
• What kind of media on which to store the backup.
• Where to store the backup data.
Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others.
In order to ensure company good name, integrity and longevity, data must be stored in multiple locations; this is no longer only “nice to have”, it is a necessity.
Nowadays reasons for data loss are numerous: fire, flood, earthquake, theft, fraud, destruction, human error, hardware failure, software failure, viruses… More than 35% of all attacks are inside jobs, perpetrated by trusted employees with high security clearance. Backing up to physical media such as external drives, USB, DVD, CD, etc. violate compliance regulations and pose serious security risks as they can easily be lost or stolen. Regardless of how good your hardware and software are and how well you maintain your system, you cannot guarantee that your data will be safe if it’s stored in only one location. As we say in the industry, if it doesn't exist in at least three locations —one of them offsite —it doesn't exist!
Causes of Data Loss

Datastore Disaster Recovery
Disaster recovery consists of the policies and procedures that describe how to recover or continue the technology infrastructure critical to an organization after a disaster. This cryptographic method protects sensitive data by encoding and transforming information into unreadable cipher text. Encoded data may only be decrypted or made readable with a key. Symmetric-key and asymmetric-key are the two primary types of encryption.
Encryption is a type of security that converts data, programs, images, or other information into unreadable cipher. This is done by using a collection of complex algorithms to the original content meant for encryption. Encryption is essential for ensured and trusted delivery of sensitive information.
Symmetric forms of encryption systems make use of a single password to serve as both decryptor and encryptor. Symmetric-key encryption uses two secret, often identical keys or codes for computers involved in message transmission. Each secret key's data packet is self-encrypted. Symmetric types use algorithms that are very safe. One of such type was adopted by the US Government as Advanced Encryption Standard (AES) to store classified information. The Advanced Encryption Standard (AES) is considered more reliable because it uses a 128-bit, a 192-bit or a 256-bit key.
Asymmetric-key encryption, also known as public-key encryption, uses two keys, referred to as a key pair. One is a public key, and the other one is a private key. The public key can be freely shared among various users as it is only meant for encryption. The private key is not shared, and is used to decrypt anything that was encrypted by the public key.
Disaster Recovery as a Service (DRaaS) is a cloud computing and backup service model that uses cloud resources to protect applications and data from disruption caused by disaster. It gives an organization a total system backup that allows for business continuity in the event of system failure. DRaaS is often offered in conjunction with a disaster recovery plan (DRP) or business continuity plan (BCP).
DRaaS enables the full replication and backup of all cloud data and applications while serving as a secondary infrastructure. It actually becomes the new environment and allows an organization and users to continue with daily business processes while the primary system undergoes repair. DRaaS allows these applications to run on virtual machines (VM) at any time, even without a real disaster.
DRaaS advantages are as follows:
• Multisite - resources are replicated to many different sites to ensure continuous backup in the event that one or more sites is unavailable.
• Granular or comprehensive – Depending on customer requirements, if not all data requires backup, an organization can reduce costs with flexibility protection.
• Rapid and Immediate Recovery – with a DRaaS solution in place, if a disaster strikes, you will be able to restore normal operations within minutes.
• Flexibility – various DRaaS services offer clients more options in how to handle different business systems. Any enterprise using DRaaS solutions can select from a variety of recovery scopes, depending on the type of the disaster. These can include server failure, human-caused disasters, loss of power or building access, data hampering, and much more.
• No offsite transportation and storage cost.
• Fast restore for minimal impact on your business.
• You only pay for the storage you use (compressed & deduplicated).
• Supported Applications & Systems.
• Central administration.
