The installation ISO image is available for free download. Distribution-specific components are open under the AGPLv3 license. For updates, both a paid Enterprise repository and two free repositories, differing in update stabilization levels, are available.       <\/p>\n<p>The system part of the distribution is based on the Debian 10.9 (Buster) package base, Linux kernel 5.4, and OpenZFS 2.0. The software stack for backup management is written in Rust and supports incremental backups (only changed data is transferred to the server), deduplication (only one copy is stored when duplicates exist), compression (using ZSTD), and encryption of backups. The system is designed based on a client-server architecture \u2014 Proxmox Backup Server can be used for both local backups and as a centralized server for backing up data from various hosts. Fast selective recovery and data synchronization modes between servers are provided.    <\/p>\n<p>Proxmox Backup Server supports integration with Proxmox VE for backup of <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/vps\/\"   title=\"of virtual machines\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2051\">of virtual machines<\/a> and containers. Backup management and data recovery are conducted through a web interface. There is an option to restrict user access to their data. All traffic transmitted from clients to <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-shicago\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2893\">server<\/a> is encrypted using AES-256 in GCM mode, and the backups themselves are transmitted already encrypted using asymmetric encryption with public keys (encryption is performed on the client side, so server compromise will not lead to data leaks). Backup integrity is verified using SHA-256 hashes.       <\/p>\n<p>In the new release:  <\/p>\n<ul>\n<li class=\"l\"> Synchronization with the Debian 10.9 'Buster' package base has been completed.\n<li class=\"l\"> The ZFS filesystem implementation has been transitioned to OpenZFS 2.0.\n<li class=\"l\"> Support for tape drives that support the LTO (Linear Tape-Open) format has been added.\n<li class=\"l\"> Support for saving and restoring storage using a pool of tape drives has been introduced.\n<li class=\"l\"> Flexible policies for determining data retention periods have been implemented.\n<li class=\"l\"> A new driver for tape drives has been added, operating in user space and written in Rust.\n<li class=\"l\"> Support for managing automatic cartridge feeding mechanisms in tape drives has been added. To control autoloaders, the utility pmtx has been proposed, which is an equivalent of the mtx utility rewritten in Rust.\n<li class=\"l\"> Sections for configuring components, jobs, and executing tasks on schedule have been added to the web interface.\n<li class=\"l\"> The Proxmox LTO Barcode Label Generator web application has been added for generating and printing barcode labels.\n<li class=\"l\"> Two-factor authentication support using one-time passwords (TOTP), WebAuthn, and one-time recovery keys has been added to the web interface.      <\/ul>\n<p>Source: <a
