    Considerations and Limitations (Linux)

    OS

    • Only GA versions of the supported distributions that have been released before the current version of Veeam Agent for Linux are supported.
    • The Linux OS must be set up to receive software updates from the default repositories enabled in the OS after installation.
    • For cloud-based installations that use customized kernels (such as Linux distributions deployed from AWS Marketplace or Azure Marketplace), the veeamsnap kernel module has experimental support status. For details about experimental support, see this Veeam KB article.
    • Automatic Veeam Agent deployment from the Veeam backup console is not supported for the following distributions:
    • Fedora 33, 34
    • openSUSE Tumbleweed
    • Debian 11

    You need to install Veeam Agent for Linux directly on a target computer. For details, see the Installing Veeam Agent for Linux section in the Veeam Agent for Linux User Guide.

    • RHEL, CentOS, and Oracle Linux (RHCK) are supported up to certain kernel versions. For details, see this Veeam KB article.

    File System

    For the kernel version 4.13 or later, if a value of extended attribute exceeds the limit, Veeam Agent uses the ea_inodes feature. Backups created using the ea_inodes feature cannot be mounted on kernel versions up to 4.12.

    • BFQ I/O scheduler is not supported.
    • Sparse files are not supported. Veeam Agent backs up and restores sparse files as regular files.

    Software

    System Requirements IMPORTANT

    Linux user account used to work with Veeam Agent for Linux installed on the protected computer must have the /bin/bash shell set as the default shell.

    For details, see the Installing Veeam Agent for Linux section in the Veeam Agent for Linux User Guide.

    • Version of the following packages varies according to the Linux kernel version that you use:
    • linux-headers (for Debian-based systems)
    • kernel-headers (for RedHat-based systems)
    • kernel-devel (for RedHat-based systems)
    • linux-image-<version>-dbg (for Debian 11.0)

    where <version> — the Linux kernel version that you use

    • For openSUSE and SLES distributions, either of the following packages is required: libncurses5 or libncurses6.
    • The dmidecode package is required for Veeam Agent management — a valid BIOS UUID must be obtainable either from dmidecode | grep -i uuid or from /sys/class/dmi/id/product_uuid. Each Veeam Agent that consumes a license installed in Veeam Backup & Replication must have a unique BIOS UUID. If a valid UUID cannot be obtained, Veeam will generate it automatically.
    • The libmysqlclient package is required to process MySQL database system located on the Veeam Agent server. Package version varies according to the MySQL database system version that you use.
    • The libpq5 package is required to process PostgreSQL database system located on the Veeam Agent server.
    • The python3 package or another RPM package providing a /usr/bin/python3 binary is required for CentOS, RHEL 7.0 and later distributions if a pre-built binary kmod-veeamsnap package is to be installed.
    • The btrfs-progs package version 3.16 or later is required.
