Utgivelse av Proxmox Backup Server 1.1

Proxmox, known for its development of Proxmox Virtual Environment and Proxmox Mail Gateway, has released the Proxmox Backup Server 1.1 distribution, presented as a ready-made solution for backing up and restoring virtual environments, containers, and server data. The installation ISO image is available for free download. Distribution-specific components are open-source under the AGPLv3 license. Both a paid Enterprise repository and two free repositories, differing in update stabilization levels, are available for updating installations.

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 if duplicates are present), compression (using ZSTD), and backup encryption. The system is designed on a client-server architecture — Proxmox Backup Server can be used for both local backups and as a centralized server for backing up data from various hosts. It provides fast selective recovery and data synchronization modes between servers.

Proxmox Backup Server støtter integrasjon med Proxmox VE-plattformen for sikkerhetskopiering virtual machines og containere. Administrasjon av sikkerhetskopier og datagjenoppretting skjer via et webgrensesnitt. Det er mulighet for å begrense tilgangen for brukere til sine egne data. All dataoverføring fra klienter til server encrypted using AES-256 in GCM mode, and the backups themselves are transmitted already encrypted using asymmetric encryption with public keys (encryption is done on the client side, and compromising the server with backups will not lead to data leakage). The integrity of the backups is controlled using SHA-256 hashes.

I den nye utgaven:

• Synchronized with the Debian 10.9 'Buster' package base.
• The implementation of the ZFS file system has been updated to use the OpenZFS 2.0 branch.
• Support for tape drives that support the LTO (Linear Tape-Open) format has been added.
• Support for saving and restoring storage using a pool of tape drives has been included.
• Flexible policies for defining data retention periods have been implemented.
• A new driver for tape drives, operating in user space and written in Rust, has been added.
• Støtte for styring av automatiserte patronleveringsmekanismer i båndlagringsenheter er lagt til. For styring av automatisk lastere er det foreslått et verktøy kalt pmtx, som er en analog til verktøyet mtx, omskrevet i Rust.
• Det er lagt til seksjoner i webgrensesnittet for konfigurasjon av komponenter, arbeider og oppgaver basert på timeplan.
• Det er lagt til et webprogram kalt Proxmox LTO Barcode Label Generator for generering og utskrift av etiketter med strekkoder.
• Webgrensesnittet har fått støtte for tofaktorautentisering ved bruk av engangspassord (TOTP), WebAuthn og engangsnøkler for gjenoppretting av tilgang.
