Symantec NetBackup, Manual

Page: 23 / 168

See “Configuring an AdvancedDisk disk pool” on page 29.
Additional requirements and limitations are as follows:
■
NFS file system 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.
Note: Symantec 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.
■
Windows CIFS not supported
On Windows, networked mapped devices are not visible to Windows services,
and AdvancedDisk cannot discover Common Internet File System disk volumes.
Therefore, AdvancedDisk does not support the Common Internet File System.
About AdvancedDisk storage servers
A storage server is a NetBackup media server that mounts the disk storage and
writes data to and reads data from the disk storage.
For AdvancedDisk, NetBackup media servers function as both storage servers and
data movers.
See “About AdvancedDisk data movers” on page 23.
Multiple storage servers can exist. The storage servers share the storage equally.
About AdvancedDisk data movers
A data mover transfers data from primary storage (a NetBackup client) to
secondary storage during backups. It also can move data back to primary storage
during restores and from secondary storage to tertiary storage during duplication.
You do not configure data movers separately. For AdvancedDisk, NetBackup media
servers function as both storage servers and data movers. Data movers are
configured when you configure storage servers.
