Main Features
Support for Proxmox VE
The Proxmox Virtual Environment is fully supported and you can easily backup
virtual machines (supporting QEMU dirty bitmaps) and containers.
Performance
The whole software stack is written in Rust, to provide high speed and memory
efficiency.
Deduplication
Periodic backups produce large amounts of duplicate data. The deduplication
layer avoids redundancy and minimizes the used storage space.
Incremental backups
Changes between backups are typically low. Reading and sending only the delta
reduces storage and network impact of backups.
Data Integrity
The built in SHA-256 checksum algorithm assures the accuracy and consistency of
your backups.
Remote Sync
It is possible to efficiently synchronize data to remote sites. Only deltas
containing new data are transferred.
Compression
The ultra fast Zstandard compression is able to compress several gigabytes of
data per second.
Encryption
Backups can be encrypted on the client-side using AES-256 in Galois/Counter
Mode. This authenticated encryption mode provides very high performance on
modern hardware.
Web interface
Manage Proxmox backups with the integrated web-based user interface.
Open Source
No secrets. Proxmox Backup Server is free and open-source software. The source
code is licensed under AGPL, v3.
Support
Enterprise support will be available from Proxmox.
