Restoring Cluster Files Overview

The ufsrestore(1M) command copies files to disk, relative to the current working directory, from backups created using the ufsdump(1M) command. You can use ufsrestore to reload an entire file system hierarchy from a level 0 dump and incremental dumps that follow it, or to restore one or more single files from any dump tape. If ufsrestore is run as superuser or assume an equivalent role, files are restored with their original owner, last modification time, and mode (permissions).

Before you start to restore files or file systems, you need to know the following information.

• Which tapes you need

• The raw device name on which you want to restore the file system

• The type of tape drive you will use

• The device name (local or remote) for the tape drive

• The partition scheme of any failed disk, because the partitions and file systems must be exactly duplicated on the replacement disk
