In this way, users can easily access and manage their files from any of their devices. For example, services such as iCloud and Microsoft OneDrive offer mobile app and web interface support.

These features enable cloud backup systems to securely store, manage and share users' data. This allows users to easily access their files anytime and anywhere. Well, let's look at what technologies are used to provide these common features. Although each system has its own algorithms, systems and methods, we know that some common methods are also used. If we explain these in detail;

1.      Data Security: All cloud backup systems take various security measures to ensure the security of users' data. These measures include data encryption, access control, secure communication protocols, and physical security measures. We can give examples of some of the encryption algorithms and measures used as follows.

 

Data Encryption Methods and Algorithms;

·        End-to-End Encryption: In this method, data is encrypted on the user device and only the encrypted version is stored in the cloud. Encrypted data can only be decrypted with a private key provided by the user. This way, even the data provider cannot access user files. For example, services such as Box, GitHub, Gitlab, SpiderOak, and Tresorit use end-to-end encryption.

·        AES (Advanced Encryption Standard): This is a strong and widely used symmetric encryption algorithm. AES is used to encrypt data with different key lengths (128, 192 or 256 bits). For example, services like Dropbox and Google Drive use AES encryption.

·        RSA (Rivest-Shamir-Adleman): This is an encryption algorithm often called asymmetric encryption. RSA is a public key cryptography system and is often used for secure communications and digital signing. For example, services such as Microsoft OneDrive and iCloud use RSA encryption.

·        SHA (Secure Hash Algorithm): This is a cryptographic hash function often used to verify data integrity. SHA algorithms produce a unique cryptographic hash of the data of a fixed size. For example, services such as Amazon S3 and Backblaze B2 ensure data integrity using SHA hash functions.

 

Access Control Methods:

Controlling access to data is another crucial aspect of ensuring data security. Access control is achieved through user authentication and authorization. Users are granted access only to designated resources based on their permissions. For example, access control is facilitated using authorization protocols like OAuth 2.0 and authentication methods such as JSON Web Tokens (JWT).

 

Secure Communication Protocols:

Secure communication protocols are employed to ensure that data is transmitted securely. Protocols like SSL (Secure Sockets Layer) and TLS (Transport Layer Security) encrypt data during transmission, establishing a secure communication channel.

 

2.     Backup and Restore Capabilities: Backup software in cloud backup systems is designed to regularly backup users' files and restore them when needed. Many software technologies and algorithms are used to provide this functionality.

·        Data Deduplication: Data deduplication identifies redundant blocks among backed-up data, resulting in storage space savings. This technology prevents the storage of multiple copies of large files or files with the same content. For example, services like Backblaze and Carbonite utilize data deduplication technology to save storage space.

 

·        Compression: Compression is a technique used to reduce the size of backed-up data. This technology compresses data files to save storage space. For instance, services like SpiderOak reduce data size during backup operations using compression algorithms.

 

·        Incremental Backup: Incremental backup is a technique that allows the user to back up only the changed portions of their files. Instead of re-backing up all files in each backup operation, only the changed or newly added file parts are backed up. This speeds up the backup process and saves storage space.

 

·        Parallel Processes and Distributed Systems: Data backup systems generally use parallel processes and distributed systems to speed up backup processes and provide scalability. These technologies are necessary to efficiently process and store large amounts of data. For example, services such as Box and Dropbox speed up backup processes by distributing files across different servers using distributed systems.

These software technologies make the data backup processes of cloud backup systems more efficient, secure and scalable. This allows users to safely back up their files and restore them when necessary.

3.     Sync and Sharing:

Cloud backup systems allow users to synchronize their files between different devices and share files with other users. These features allow users to access and share files easily from any of their devices.

Synchronization Technologies:

·        File Sync: It is the technology that ensures that if users update or change files, these changes are automatically transmitted to cloud servers and other synchronized devices. This allows users to access the latest updated files from any of their devices.

·        Client-Application Synchronization: Client application-based synchronization allows users to synchronize files through client applications connected to cloud services. These applications usually offer the user the ability to select a specific folder and automatically synchronize the files in that folder.

 

Sharing Technologies:

• Sharing Links: Users can create custom sharing links to share files with other users. These links are sent to people who have permission to access the file, allowing files to be easily shared.

• User Permissions: Users can determine the level of access to the files they share. For example, they can share files with only view or edit permissions.

Examples:

• Dropbox: Dropbox uses its own Dropbox application to provide file synchronization. This app allows users to automatically sync their files by selecting a specific folder. It enables sharing of files via share links and allows users to determine the level of access to files.

• Google Drive: Google Drive provides file synchronization and sharing through a web-based interface. When users add files to the Google Drive folder, these files are automatically synced and mirrored on other devices. Sharing options allow users to specify the level of access to files and sharing links.

 

4. Scalability and High Availability:

Cloud backup systems are generally built on a scalable infrastructure and are prepared to store and process large amounts of data. Additionally, they offer high accessibility so users can access their files anytime and anywhere.

Software Methods and Technologies:

·        Distributed File System (DFS): It is a method used to store and manage large amounts of data. DFS balances the load and increases scalability by distributing data across different servers. For example, technologies such as Hadoop Distributed File System (HDFS) are used for big data storage and processing.

·        Distributed Database Systems: Balances the load and increases scalability by distributing database systems across different servers. These systems enable parallel storage and processing of data. For example, NoSQL database systems such as Cassandra and MongoDB are distributed database solutions that are scalable and offer high availability.

·        Load Balancing and Auto Scaling: Cloud backup systems automatically scale in high traffic situations, providing more resources. This ensures that users always receive stable service. For example, cloud providers such as Amazon Web Services (AWS) and Google Cloud Platform (GCP) provide load balancing and autoscaling features.

·        Data Backup and Replication: Backing up and duplicating data across multiple regions ensures high availability. This ensures that data is protected in cases of data loss and service interruptions are prevented. For example, services such as Amazon S3 and Google Cloud Storage allow data to be backed up and replicated in different geographical regions.

·        Uninterrupted Services: Cloud backup systems provide high availability and redundancy to ensure uninterrupted services. This ensures that users continue to receive service even in the event of system maintenance or malfunction. For example, AWS's Continuous Delivery and Google Cloud Platform's Instant Backup features help ensure uninterrupted services.

Above, we talked about the methods used in cloud systems in terms of security, usability, accessibility and shareability.

For example, containerization platforms such as Docker and Kubernetes can be used for rapid deployment and management of applications in cloud backup systems. 

Example: A cloud backup provider can provide backup and storage of data by running on virtual machines or containers dedicated to customers.    

2.       Load Balancing and Auto Scaling

·        Load Balancing: Load balancing technologies improve performance and reduce service interruptions by distributing incoming requests evenly among different servers or services. For example, load balancers such as Nginx or HAProxy optimize incoming data flow in cloud backup systems.

·        Auto Scaling: Auto scaling allows system resources to be automatically increased or decreased based on demand. For example, Amazon Web Services (AWS) Auto Scaling or Google Cloud Platform's auto-scaling features can be used in cloud backup systems.

Example: Heavy data traffic to a cloud backup system is managed by the load balancer by distributing it across different servers and increasing it with automatic scaling.

3.      API and Web Services

·        APIs: RESTful APIs are first-class interfaces used by customers of cloud backup systems. APIs allow customers to automate data backup, restore and management.

·        Web Services: Cloud backup systems often provide web-based management interfaces. These interfaces enable users to visually manage their data and offer functionality provided through APIs.

Example: Dropbox's RESTful API allows developers to integrate their applications with Dropbox, while Google Drive's web-based interface provides users with a user-friendly experience for data backup and synchronization.

 

4. Security and Identity Management

·        Encryption: Cloud backup systems use strong encryption algorithms to encrypt user data before and after storage. This ensures the security of the data.

·        Access Control: Access control mechanisms are used to prevent unauthorized access to data. Users are ensured to access only the data for which they are authorized.

·        Authentication and Authorization: Authentication and authorization of users are critical to the security of cloud backup systems. Single-factor or multi-factor authentication methods can be used.
