官方最新消息 Proxmox Backup Server 2.0 available

此版改版內容

Released 13. July 2021

  • Based on Debian Bullseye (11)
  • Kernel 5.11
  • ZFS 2.0

  • Changelog Overview

    • Tape Backup:
      • Matured from technology preview to the first stable release
      • Improve restore flexibility, allowing you to select multiple snapshots for one restore job
      • Read chunks sorted by inode on backup, to leverage improved read speed on slow spinning disks with increased sequential access

  • Backend:

    • Support for Single-Sign-On (SSO) with the new OpenID Connect access realm type

      You can integrate external authorization servers, either using existing public services or your own identity and access management solution, for example, Keycloak or LemonLDAP::NG.

    • ACME/Let's Encrypt integration with stand-alone and DNS Plugins, for easy deployment of trusted certificates

    • Improved caching for proxmox-backup-client map

    • Single file-restore support for VMs that use ZFS or LVM internally

    • Support setting an HTTP proxy for package updates and subscription check requests

  • Enhancements in the web interface (GUI):

    • Make dashboard status panel more detailed, showing, among other things, uptime, Kernel version, CPU info and a high level repository status overview.

    • New Repository management panel in the Administration tab shows an in-depth status and a list of all configured repositories.

      Basic repository management, for example, activating or deactivating a repository, is also supported.

    • ACME/Let's Encrypt GUI integration

    • Support setting comments on a backup group

    • Updated ExtJS JavaScript framework to latest GPL release 7.0

    • Improved translations, including:

      • Arabic
      • French
      • German
      • Japanese
      • Polish
      • Turkish

  • Installer:

    • Rework the installer environment to use switch_root instead of chroot, when transitioning from initrd to the actual installer.

      This improves module and firmware loading, and slightly reduces memory usage during installation.

    • Automatically detect HiDPI screens, and increase console font and GUI scaling accordingly. This improves UX for workstations with Proxmox VE (for example, for passthrough).

    • Improve ISO detection:

      • Support ISOs backed by devices using USB Attached SCSI (UAS), which modern USB3 flash drives often do.
      • Linearly increase the delay of subsequent scans for a device with an ISO image, bringing the total check time from 20s to 45s. This allows for the detection of very slow devices, while continuing faster in general.

    • Use zstd compression for the initrd image and the squashfs images.

    • Update to busybox 1.33.1 as the core-utils provider.

  • Known Issues

  • Network: Due to the updated systemd version, and for most upgrades, the newer kernel version (5.4 to 5.11), some network interfaces might change upon reboot:

    • Some may change their name. For example, due to newly supported functions, a change from enp33s0f0 to enp33s0f0np0 could occur.

      We observed such changes with high-speed Mellanox models.

    • Bridge MAC address selection has changed in Debian Bullseye - it is now generated based on the interface name and the machine-id (5) of the system.

      Note that by default, Proxmox Backup Server does not uses a Linux Bridge for networking, so most setups are unaffected.

  • Upgrade from 1.1
