About AdvancedDisk file system requirements

AdvancedDisk can read and write any nonshared file system that NetBackup supports. However, AdvancedDisk is subject to any operating system or file system requirements or limitations. Requirements and limitations may exist beyond those mentioned in this topic.

For supported file systems, see the NetBackup operating system compatibility list at the Veritas Support website, as follows:

http://www.netbackup.com/compatibility

The following are additional requirements and limitations for file systems:

CIFS

Windows Common Internet File System (CIFS) requirements:

  • Ensure that the Windows disk shares are configured to reconnect on login.

  • Networked mapped devices are not visible to Windows services; therefore, NetBackup cannot discover CIFS disk volumes. You must use the Windows Universal Naming Convention (UNC) to specify the CIFS volumes that you want to use for AdvancedDisk disk pools.

  • You must configure two Windows services to use the same credentials.

    See Configuring credentials for CIFS storage and disk storage units.

  • You cannot delete a disk pool that is created by specifying volumes (such as for CIFS volumes). The disk pool exists until you delete its storage server.

NFS

Network File System (NFS) requirements:

  • You must use manual mount points. Automatic mount and unmount can change mount points, which may cause disk resources to be unavailable.

  • The NFS server that exports the mount points must be configured to allow root access to the file systems.

  • NFS uses a file system paradigm to manage objects. Therefore, carefully choose the volumes to include in the disk pool.

    For example, NetBackup does not filter out common file system mount points, such as / and /usr on UNIX and Linux systems. You should not use those mount points for storage.

  • Veritas recommends that you do not span backup images across NFS volumes in an AdvancedDisk disk pool. File system full conditions cannot be detected adequately. Therefore, a disk pool based on NFS volumes should be comprised of only one volume.

ZFS

Veritas recommends that you do not span backup images across ZFS volumes in an AdvancedDisk disk pool. File system full conditions cannot be detected adequately. Therefore, a disk pool based on ZFS volumes should be comprised of only one volume.

Disk pool configuration may affect how you configure your file systems.
