System Requirements

In this article


    A machine that you plan to protect with Veeam Agent for IBM AIX must meet requirements listed in the table below.




    Memory: 1 GB RAM. For information about RAM requirements for large-scale environments, see RAM Requirements for Large-Scale Environments.

    Disk space: 1.5 GB free disk space for product installation.

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


    IBM AIX versions starting from version 6.1 up to the latest update of version 7.2 are supported.


    • IBM AIX 6.1 is supported starting from Technology Level 5 (TL 5).
    • Backup of a Virtual I/O Server (VIOS) is not supported.
    • Only GA versions of the IBM AIX operating system that have been released before the current version of Veeam Agent for IBM AIX are supported.

    File System

    All file systems supported by the supported operating systems.


    • Total size of all file systems included in a file-level backup must not exceed 128 TB.
    • The maximum number of files in one backup job is 20,000,000. To back up a greater number of files, use multiple jobs.
    • Size of a file in a backup must not exceed 16 TB.
    • Name of a file in a backup must not be larger than 254 bytes.

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

    • Sparse files are not supported. Veeam Agent backs up and restores sparse files as regular files.
    • JFS external snapshots are not supported.


    For file system indexing, the following utilities are required: tar, mlocate and gzip.

    • The tar utility is installed together with the product.
    • The mlocate utility is provided along with the product in the product installation media.
    • The gzip utility must be installed separately.

    AIX Environment

    The LIBPATH AIX environment variable on the Veeam Agent computer must be set to blank (default value). If a different value is specified for this variable, you must make adjustments to the AIX environment for proper operation of Veeam Agent. For details, see this Veeam KB article.



    Backup Target

    Backup can be performed to the following types of storage:

    • Local (internal) storage of the protected machine (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
    • Veeam Backup & Replication 11a (build or later backup repository (Veeam Cloud Connect repositories are not supported)


    Consider the following:

    • If you back up to a repository managed by a Veeam backup server, Veeam Agent for IBM AIX must be able to establish a direct IP connection to the Veeam Backup & Replication server. Veeam Agent for IBM AIX cannot work with Veeam Backup & Replication that is located behind a NAT gateway.
    • Domain names of the Veeam Agent machine, Veeam Backup & Replication server and other servers in the Veeam backup infrastructure must be resolvable into IPv4 addresses.
