Backing up file system configuration information

The mmbackupconfig command can be used to back up vital file system configuration information. This information can later be used to restore the layout and major characteristics of the file system.

The mmbackupconfig command creates a file that includes:
  • Disk information (NSD names, sizes, failure groups)
  • Storage pool layout
  • Filesets and junction points
  • Policy file rules
  • Quota settings and current limits
  • File system parameters (block size, replication factors, number of inodes, default mount point, and so on)
The output file generated by the mmbackupconfig command is used as input to the mmrestoreconfig command.
Note: The mmbackupconfig command only backs up the file system configuration information. It does not back up any user data or individual file attributes.

It is recommended that you store the output file generated by mmbackupconfig in a safe location.
