System Requirements for Nosnap Veeam Agent for Linux on Power

Starting from version 6.1, if you want to back up Linux computers running on IBM Power Systems, you can install Veeam Agent for Linux using the veeam-nosnap package for Linux on Power. This package allows Veeam Agent to operate without Veeam kernel module using the native file system snapshots instead.

Before you install Veeam Agent using the veeam-nosnap package for Linux on Power, consider the following limitations:

  • The RAM-based changed block tracking (CBT) mechanism is not supported. As a result, if you plan to back up a significant amount of data, the backup will require greater time.
  • Veeam Agent can create a snapshot of LVM logical volumes and BTRFS subvolumes. To back up data that resides on other file systems and volumes, you can use only file-level backup in the snapshot-less mode. For details, see Snapshot-Less File-Level Backup.
  • For a successful backup, Veeam Agent requires unallocated extents on volume groups.
  • For a successful bare metal restore, all disks of the Veeam Agent computer you want to restore must be available in the backup.

System Requirements for Veeam Agent for Linux on Power

If you plan to install Veeam Agent for Linux on Power, make sure the protected Linux computer meets the requirements listed in the table below. To learn about system requirements for Veeam Agent for Linux installed using Veeam kernel module package, see System Requirements.




System: IBM Power System


Memory: 1 GB RAM or more. Memory consumption varies depending on the backup type and the total amount of backed-up data. For more information, see RAM Requirements for Backup of Large Number of Files.

Disk Space: 100 MB free disk space for product installation

Network: 10 Mbps or faster network connection to a backup target

Disk layout: MBR or GPT


Important! Check considerations and limitations that apply to the list of supported OSes.

Veeam Agent supports little endian versions of the following Linux distributions for IBM Power:

  • SLES 15 SP3 and 15 SP4
  • SLES for SAP 12 SP5, 15 SP3 and 15 SP4
  • RHEL 8.4 and 8.6
  • RHEL for SAP 8.4

File System

Important! Check considerations and limitations that apply to the list of supported file systems.

Veeam Agent for Linux on Power supports consistent snapshot-based data backup for the following file systems:

  • BTRFS (for OSes that run Linux kernel 3.16 or later)

If BTRFS has additional abstraction layers (such as LVM, software RAID, dm-crypt and so on) above it, only file-level restore operations are supported. Instant Recovery, restore verification (SureBackup), bare metal recovery and volume-level restore are not supported.

Supported file systems that are not located on logical volumes, other file systems and network file systems like NFS or SMB shares can be backed up using the snapshot-less mode only. For details, see Snapshot-Less File-Level Backup.


Important! Linux user account used to work with Veeam Agent for Linux on Power must have the /bin/bash shell set as the default shell.

Protected computer must have the following components installed:

  • libacl
  • libattr
  • lvm2
    • libfuse2 (FUSE libraries for SLES-based systems)
    • fuse-libs (FUSE libraries for RedHat-based systems)
    • syslinux (for RedHat-based systems)
    • btrfs-progs (version 3.16 or later, for backup of BTRFS file system)
    • tar (for file system indexing, log export and rotation)
    • gzip (for file system indexing, log export and rotation)

    Considerations and Limitations


    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. 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.

    • The Linux OS must be set up to receive software updates from the default repositories enabled in the OS after installation.

    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.


    Consider the following:

    • During volume-level backup, data from shared disks, clustered file systems or clustered LVM will not be backed up.
    • To perform volume-level backup, Veeam Agent for Linux will create an LVM snapshot, which can cause instability of the cluster or cluster software. This can happen due to the failover conditions configured for the cluster. However, if the cluster instability is caused by creation of an LVM snapshot only during backup, please contact Veeam support for assistance.
    • Backup of clustered file systems using a native file system snapshot is not supported. This includes snapshots created with the help of custom pre-job or post-job scripts.
    • The following objects can be backed up only by snapshot-less file-level backup:
    • Files on shared disks, clustered file systems or clustered LVM
    • Files on local file systems that are not hosted by LVM
    • Sparse files are not supported. Veeam Agent backs up and restores sparse files as regular files.
    • Backup of pseudo file systems, such as /proc, /sys, tmpfs, devfs and others, is not supported.

    Backup Source

    Any file systems and devices that are accessible from the host OS. To learn about limitations, see File System.

    Backup Target

    Backup can be performed to the following types of storage:

    • On-premises or cloud-based object storage.
    • Local (internal) storage of the protected computer (not recommended).
    • Direct attached storage (DAS), such as USB, eSATA or Firewire external drives.
    • Network Attached Storage (NAS) able to represent itself as SMB (CIFS) or NFS share. Requires cifs-utils or nfs-utils packages to be installed on the Veeam Agent for Linux computer, depending on a network storage type.
    • Veeam Backup & Replication 12.1 or later backup repository (including deduplication appliances).


    Consider the following about backup repositories:

    • [For local storage] A backup repository should be created on a separate volume from the volume that contains data you plan to back up.
    • [For Veeam backup repository] Backup repositories with enabled KMS encryption are not supported.


    Consider the following:

    • Veeam Agent for Linux should be able to establish a direct IP connection to the Veeam Backup & Replication server. Thus, Veeam Agent for Linux cannot work with Veeam Backup & Replication that is located behind the NAT gateway.
    • Domain names of the Veeam Agent computer, Veeam Backup & Replication server and other servers in the Veeam backup infrastructure must be resolvable into IPv4 or IPv6 addresses.
