Hard Links to Directories

On most UNIX systems, only the root user can create a hard link to a directory. Some systems do not permit hard links and many vendors warn you to avoid using these links.

NetBackup does not back up and restore hard-linked directories in the same manner as it does files:

• During a backup, if NetBackup encounters hard-linked directories, it backs them up multiple times, once for each hard link.
• During a restore, NetBackup restores multiple copies of the hard-linked directory contents if the directories do not already exist on the disk. If the directories exist on disk, NetBackup restores the contents multiple times to the same disk location.
