If a new version of a supported Linux distribution is released after the release of the current version of Veeam Agent, Veeam Agent may require a patch to support this new OS version. For details on Veeam Agent compatibility with Linux OS versions, see this Veeam KB article. Customers with a valid contract can request a patch from Veeam Support; for other customers, the support of the new Linux distribution will be provided with the next release of Veeam Agent.

  • To ensure proper functioning of the veeamsnap kernel module, verify that the Veeam Agent computer does not have any of the following modules installed: hcdriver, snapapi26, snapapi, snapper, dattobd, dattobd-dkms, dkms-dattobd, cdr or cxbf.
  • 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, 35
  • openSUSE Tumbleweed

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.
  • Ubuntu 21.10 minimal install is not supported.

 

File System

Keep in mind that characters that you can use in the file name may be encoded in 2 bytes or more.

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.
