Chapter 3 Back Up the System to an NFS-Mounted Directory
12
Back Up the File System to an NFS-Mounted
Directory
The file system can be backed up to a directory that is located on an NFS-mounted
file system. You must be able to access the NFS directory through the
/net/[remotehost]/[path_to_NFS_directory] directory structure. In addition, you
must have write-access to the directory or the backup will fail.
Note: Procedures for setting up the NFS are beyond the scope of this document. See
your System Administrator, if necessary, for help in setting up the NFS.
Important: All commands in this procedure must be executed as root user. We
recommend creating an FS (for file system), and DBKF (for database and key files)
directory in the NFS directory path.

1 Ensure that you have write-access to the NFS-mounted file system and backup
directory.
2 To back up a file system over NFS, type the following command and press Enter.
/usr/local/backup_restore/backupFileSystems –v –B
/net/[remotehost]/[path_to_NFS_directory/[hostname]/FS
Notes:
The [remotehost] should be replaced with the actual hostname or IP address
of the remote computer system which is exporting (or shares) the file system
into which you will write the backup.
of the remote computer system which is exporting (or shares) the file system
into which you will write the backup.
The -B option allows you to define a backup directory path.
The [path_to_NFS_directory] represents the directory path on the remote
host which will hold the backup files.

The [hostname] should be replaced with the hostname of the system you are
backing up.

This can be a very lengthy command. Type to the end of the command before
you press Enter. The command is likely to wrap to the following line.
