Recover Data
Recover Data	To support data recovery due to a disk crash, the following tasks
	are required:

	Task	Page

	Dump Data	4-9

	Restore Data	4-11

	Audit Database	4-17
Dump Data
Dump Data	The fsdump command is used to perform a dump of each file
	system.

Note

For more information on the fsdump command, refer to the Command Reference book.

Enter a -fdumpfilename to specify the file system to be dumped.

The fsdump command creates a fs_dump.file for each file system dumped. The file system must be mounted for the file to be created. The file is dumped with the files in the file system. Then, the file is removed from disk.

When used with the UNIX xfsrestore command and the FileServ fsaudit command, any file system that contains migration directories can be restored.
