Recover Data
To support data recovery due to a disk crash, the following tasks
are required:
Dump Data
The fsdump command is used to perform a dump of each file
system.
Enter a -f dumpfilename to specify the file system to be
dumped.
The f
sdump 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.
