Proxmox Backup

The Proxmox Backup Service has several key aspects of great interest, let's see together:

Implementation and Programming Language: Proxmox Backup Server is entirely written in Rust, offering high performance and low memory usage. It uses advanced encryption in both client server communication and the security of backed up data, ensuring high performance without compromising on security or flexibility.

Data Management and Snapshots: The system supports incremental backups and data deduplication, significantly reducing the required storage space and the load on the network. The data is divided into chunks, or blocks, which can be of fixed or dynamic size, further optimizing space management and deduplication efficiency.

Data Security and Integrity: Proxmox Backup Server guarantees data integrity with checksums and allows the encryption of data chunks, which can be transferred securely even to destinations that are not completely reliable. The server also manages secure backups to prevent accidental removal and supports live restore, allowing users to boot virtual machines directly from ongoing backups, reducing downtime.

Installation and Configuration: The installation can run on dedicated hardware using an ISO image, with built-in support for ZFS. Proxmox offers a web interface for simplified management, making it easy to set up and maintain the backup system.

Package Repository Management: Proxmox provides managed package repositories that allow users to receive stable and secure updates , ensuring maximum reliability for use in production environments. There are several subscription options available to access repositories that include the most stable versions of the packages.

How can I configure Proxmox Backup Server to optimize data deduplication?
Deduplication in Proxmox Backup Server is optimized by using data chunks that reduce the amount of storage space needed. To improve deduplication efficiency, we recommend using chunks of a size appropriate to the data type and modifying backup settings to take advantage of cross-snapshot deduplication when possible.

You can back up machines virtual machines running without interruption?
Yes, Proxmox Backup Server supports live backup of virtual machines without the need to stop running services. This is made possible through the use of technological snapshots that capture the current state of the VM without interrupting operations. During the backup process, data changes are tracked to ensure that the backup reflects the current state when the backup began.
