PRIMECLUSTER Global File Services Configuration and Administration Guide 4.2 (Solaris(TM) Operating Environment)

24.1 Types of Backups and Restores

The following describes the types of backups and restores for GFS Shared File Systems.

• Backing up and restoring file by file
  • The GFS Shared File System backup and restoration tools sfcdump(1M) and sfcrestore(1M) have the same functions as the UFS ufsdump(1M) and ufsrestore(1M) commands.
  • General-purpose backup tools not dependent on the file system structure (ArcServe/OPEN, Solstice Backup, etc.)
  • Standard Solaris OE commands cpio(1) and tar(1)

• Backing up and restoring the entire file system
  • Standard Solaris OE command dd(1M)
  • Support tool sfcmkbkup(1M) for backing up and restoring by executing the dd(1M) command

Commands that depend on the file system structure, such as UFS ufsdump(1M) and VxFS vxdump(1M), cannot be used to backup a GFS Shared File System.

Use sfcdump(1M) instead.

The following describes the types of backups and restores of GFS Shared File System data covered in this chapter.

• backing up and restoring data using sfcdump / sfcrestore(1M) (24.2)
• backing up and restoring data using sfcmkbkup(1M) (24.3)
• backing up and restoring data using Standard Solaris OE commands cpio(1), tar(1) and dd(1M) (24.4, 24.5)
