I- Architecture of Veeam Backup & Replication

Veeam Backup & Replication uses several key components to facilitate data backup and replication in virtual environments. Below is a detailed exploration of each component:

1- Key Components of Veeam

• Source hosts and associated Datastores

Source hosts represent the physical or virtual servers on which the virtual machines (VMs) to be backed up reside. Each source host is associated with datastores, which are the storage locations for the VMs[FD1].

• Backup proxies

Backup proxies play a crucial role in the backup process. They act as gateways between source hosts and the backup repository. Proxies are responsible for collecting data from VMs, compressing it and sending it to the backup repository. They also optimise data transfers to maximise efficiency and minimise the performance impact on source servers.

• Backup Repository

The backup repository is the location where backup data is stored. It can be local storage, network storage (NAS), or even cloud storage. The backup repository retains backup files and ensures their availability for subsequent restores.

• Guest interaction proxies

Guest interaction proxies are used for Windows VMs to deploy non-persistent runtime components or, if necessary, persistent agents on guest operating systems. These agents facilitate the management and backup of data at the level of each VM, ensuring comprehensive protection of application data.

• Gateway Server (For shared folder repositories)

For shared folder backups, a gateway server is deployed. This server has access to the shared folder backup repository and plays a central role in the secure transfer of data between backup proxies and the repository.

How the backup process works

When a new backup session is initiated, Veeam Backup & Replication orchestrates several key actions to ensure data protection:

• Deployment of runtime components: Guest interaction proxies or gateway servers deploy the necessary agents on the guest operating systems of VMs, ensuring complete data capture.
• Data collection and transformation: Backup proxies collect data from the VMs to be backed up, compress it and prepare it for transfer to the backup repository.
• Data transfer and storage: Veeam Data Movers, both on the source side and the target side, manage the secure transfer of data between source hosts and the backup repository. They optimise data flows by using deduplication and compression methods to minimise the required storage space and accelerate backup times.

3- On-site and off-site Backup

For on-site and off-site backups, Veeam uses specific configurations:

• On-Site Backup : Data is transferred via LAN, using local backup proxies to minimize latency and maximize performance.

• Off-Site Backup : Data is transferred via secure WAN connections, using distributed backup proxies between the source site and the remote site to optimize transfer efficiency.

The architecture of Veeam Backup & Replication is designed to provide efficient, secure, and comprehensive management of backups and data replications in virtual environments. By using a combination of backup proxies, backup repositories, and Veeam Data Movers, Veeam ensures the availability and protection of critical data for businesses of all sizes and industries.

II- Advanced backup features

1- Forever incremental backup

Forever Incremental backup is an advanced feature offered by Veeam Backup & Replication that revolutionises the way data is backed up and managed. This approach is designed to optimise backup processes while minimising the resources required and accelerating backup times.

2- Forever incremental backup concept

Forever Incremental backup is based on the principle that, after an initial full backup, only the changes made to the data since the last backup are recorded. This model avoids creating repetitive full backups, which can consume significant storage space and time.

• Initial full backup : The first backup performed is a full backup, which captures the entirety of the data. This full backup serves as the base for subsequent incremental backups.
• Incremental backups : After the initial full backup, only changes made to the data are saved during incremental backups. These backups are performed on a regular basis, capturing only the changes since the last incremental backup.
• Full backup retention: Unlike other approaches, Forever Incremental backup does not require the creation of new full backups. Incremental backups are retained alongside the initial full backup, enabling granular restoration while maintaining minimal storage consumption.

​3- Reduction of resource impact

One of the main advantages of Forever incremental backup is the significant reduction of the impact on resources, both in terms of storage and performance:

• Storage efficiency: By avoiding the need to create repetitive full backups, forever incremental backup significantly reduces storage space consumption. Only data modified since the last incremental backup is stored, which optimizes space utilization.
• Network resource optimisation: Forever incremental backup minimises the amount of data transferred over the network by backing up only changes since the last backup. This reduces the load on the network and improves the efficiency of backup operations.
• Performance management : The incremental backup process is generally faster than full backups, as it focuses solely on changes made to the data. This reduces backup windows and minimises the impact on system performance during backup operations.

Acceleration of backup times

Forever Incremental backup also contributes to accelerating backup times, which is crucial for production environments where downtime must be minimised:

• Fast Restore : By using the initial full backup as a base and integrating incremental backups, restore processes are faster. Data can be quickly restored from the combination of the full backup and increments, without requiring a new full backup.
• Reduced backup windows : The reduction in size of incremental backups compared to full backups allows for shorter backup operation durations. This enables organizations to reduce backup windows and optimize available resources.

The Forever Incremental backup offered by Veeam Backup & Replication provides an effective solution for backup management by minimising the impact on resources and accelerating backup times. This approach enables companies to protect their data more efficiently while guaranteeing optimal availability and performance.
