5.1 Backing Up and Restoring by sfxdump and sfxrestore

The sfxdump and sfxrestore commands are backup and restoration tools for GFS Local File Systems. The commands have the same functions as the ufsdump and ufsrestore commands in UFS. The following is the main features of the sfxdump and sfxrestore commands:

• Multiple backup and restoration

  The entire file system can be backed up, Incremental backup or backup as individual files can also be executed. The file system can be restored from these backups.

• Multiple tape support

  A file system can be backed up on multiple tapes. Therefore, if the contents of a file system or file to be backed up cannot be stored on one tape, the contents can be backed up on multiple tapes.

• Command line interface compatibility with ufsdump/ufsrestore

  GFS Local File Systems can be backed up and restored using the same command line interface as that of the ufsdump and ufsrestore commands in UFS.

Note the following about compatibility between the ufsdump/ufsrestore and sfxdump/sfxrestore commands:

- Backup data created by the ufsdump command is not compatible with that by the sfxdump command. The sfxrestore command cannot restore the data backed up by the ufsdump command. In the same way, the usfrestore command cannot restore the data backed up by the sfxdump command.

- The sfxdump command can back up only GFS Local File Systems. In addition, the ufsdump command cannot back up GFS Local File Systems.

This section explains how to execute the sfxdump and sfxrestore commands to back up and restore GFS Local File Systems. For information on the sfxdump and sfxrestore commands, refer to the Appendix B, "Reference Manual."
