Between Veeam and Co. - Proxmox Backup

As an IT service provider, I am confronted with various software solutions on a daily basis. My colleagues in enterprise environments often use Veeam and similar software. Although this software is perfectly designed for its purpose, I have always been a big fan of open source software. I recently came across the Proxmox Backup Server. Similar to how other solutions have a focus point, e.g. Veeam and VMWare in the use case, Proxmox Backup Server also has its optimized area. As expected, Proxmox Backup Server is optimized for the Proxmox VE. A complete open source hypervisor. The host backups or actually it should be called file level backup. The Proxmox Backup Server is a Debian Linux-based solution that can be installed as a virtual appliance (also under Proxmox VE) or as a hardware appliance. The PBS uses a proprietary chunking process to enable efficient deduplication and compression of data. It provides a web-based user interface that is easy to use and an intuitive method for creating and managing backup jobs. The PBS does not in itself support normal full and incremental backups as they are traditionally known. It rather uses a process called chunking. Chunking The Proxmox Backup Server uses the chunking process to break up large files into small, efficient pieces, similar to a jigsaw puzzle. These pieces are then deduplicated and compressed to optimize the backup process. The PBS creates a guide to reassemble these puzzle pieces later. Chunking is a process that divides large files into small, equally sized pieces (chunks), which can then be deduplicated and compressed. The Proxmox Backup Server uses a variable chunk size that is automatically adjusted to the size of the data in order to achieve optimal deduplication. This means that the PBS only saves the changes between the chunks, thus reducing the amount of data and shortening the backup time. When restoring data, the chunks are reassembled to restore the original file. Because each chunk is assigned a unique hash value, the PBS can also ensure that data integrity is maintained during the backup and restore process. In addition to this chunking process, the Proxmox Backup Server also provides support for encryption and compression of backup data to maximize the security and efficiency of the backup process. For block-based backups, the Proxmox Backup Server uses a fixed chunk size of 4 MiB. This type of backup is typically used for virtual machines and is based on the block level, which means that changes to the entire virtual disk are detected and backed up. For file-based backups, however, the Proxmox Backup Server uses a variable chunk size of 64 KiB to 4 MiB to achieve optimal deduplication of data. File-based backups are based on the file level and allow the backup of specific files or directories instead of the entire hard disk. File-based backups I currently have the backups in use with two methods, firstly I was amazed that these backups work incredibly well in Docker environments. As well as in cases where I want to backup the contents of a VM, e.g. our Mailcow at Netcup. The host backups from the PBS run via the cli tool proxmox-backup-client which is available from Proxmox. I create a bash script which is accessed via a cronjob. In reality this would look like this. First of all, this article is in no way sponsored. Becker Software is not affiliated with Proxmox.
