A remote, online, or managed backup service, also branded as cloud backup or backup-as-a-service, is a service that offers a backup, storage, and recovery mechanism for computer files for users. Online backup providers are companies which provide end-users (or clients) with this type of service. These backup services are used as cloud computing.
Usually online backup systems are designed for a client software program that runs on a given schedule. Some systems run once a day, usually in the evening when machines are not in operation. Other newer cloud backup systems are operating continuously to record user-system changes almost in real-time.
The online backup program usually stores, compresses, encrypts, and transfers the data to servers or off-site equipment from the remote backup service provider.
There are several devices on the market – all offering various feature sets, levels of service, and forms of encryption. Providers of this form of service also target different segments of the market. High-end LAN backup systems that provide services such as Active Directory, remote control of clients, or backups of open data. User online backup companies also provide beta product solutions and/or free-trial backup services with fewer options for live support.
Here are the characteristics of the Remote Backup Service
- The assurance, promise, or confirmation that what was backed up can be retrieved if appropriate is important. To ensure their recoverability, data stored in the cloud of the service provider must undergo regular integrity validation.
- Cloud BUR (BackUp & Restore) services need to have a range of granularity for RTO (Recovery Time Objective) services. One size does not suit anything inside a customer’s environment, either for the customers or the applications.
- In order to back up and retrieve data, the customer will never have to handle the storage facilities at the top.
- The system the customer uses must require data to be chosen to preserve or recover, retention times to be set, destruction dates, and schedule.
- Cloud backup has to be an ongoing process where data from the systems that hold the original copy is retrieved. This means that cloud backup does not require copying data into a specific device from where data is collected before it is transmitted and stored in the data center of the service provider.
- Cloud BUR uses common networking protocols (which are mostly based today, but not solely on IP) to transfer data between the user and the service provider.
- Vaults or repositories must always be available to restore data via private or public networks to any location connected to the Cloud of Service Providers.
Scalable and Elastic
- The Cloud BUR allows for versatile, unrestricted allocation of computing space to clients. Storage is requested and de-allocated when customers uninstall backup sets when they age.
- The Cloud BUR allows a service provider to allocate a client’s storage capacity. When that customer then deletes their data or no longer needs that power, the service provider will then immediately transfer and reallocate the same power to another customer.
- Cloud Backup allows clients to balance the data value with the cost of preserving it. This is procured on a monthly basis, per gigabyte. Prices continue to differ according to data age, data form (email, databases, files, etc.), length, number of backup copies, and RTOs.
Shared and Secured
- Cloud Backup ‘s underlying enabling technology is a full-stack, multitenant native cloud platform (shared everything).
- Data mobility/portability avoids the lock-in of service providers and enables consumers to transfer their data from one service provider to another or fully back into a dedicated private cloud (or hybrid cloud) network.
- Cloud Safety is important. One company will never have access to data from another. Furthermore, even service providers must not be able to access data from their customers without the customer’s permission.
Enterprise-class backup cloud
- Regardless of unreliable Internet access, an enterprise-class cloud storage system must have an on-premises cache to resolve any issues.
- Hybrid cloud backup works by saving data to a local disk such that the backup can be retrieved at high speed, and then either the backup program or the D2D2C (Disk to Cloud) device encrypts and transmits data to a service provider. It provides local disaster safety. To speed up data recovery activities, recent backups are stored locally.
- There are a number of cloud storage devices on the market which can be used as a backup target, including CTERA Networks, StorSimple, and TwinStrata appliances.
Hybrid cloud storage is also useful for users with security issues in businesses. Backup users can perform the necessary encryption operations when storing data locally before sending it to the cloud, incl. Such systems as:
- Cypher data encryption (AES 128, AES192, AES256, or blowfish)
- The Windows File Encryption System (EFS)
- Verification of previously cataloged files, thus allowing a Tripwire-like capability
- Authentication of CRAM-MD5 passwords between components (storage, client, and cloud)
- Configurable TLS (SSL) encryption of communication between each portion (storage, client and cloud);
- The computing of file data signatures with MD5 or SHA1, if configured.
Furthermore, data protection should be implemented when selecting a public cloud service provider.
The same holds true for backup data compression. To lower the network bandwidth load and improve backup speed, the local backup cache is used to compress the data before it is sent to the cloud. This is important for companies that backup massive databases such as Oracle or MS SQL, or massive files such as virtual machine images or mail server databases (EDB Exchange files).
Recent changes in the availability of CPUs make expanded use of software agents in place of enterprise cloud backup hardware appliances. The software-only solution will offer benefits including reduced complexity, easy scalability, substantial cost savings, and enhanced data recovery times.
