Preparing to Restore Files and File Systems
The ufsrestore command copies files to disk, relative to the current working directory,
from backups that were created by using the ufsdump command. You can use
the ufsrestore command to reload an entire file system hierarchy from a
level 0 dump and incremental dumps that follow it. You can also use
this command to restore one or more single files from any backup tape.
If you run the ufsrestore command as superuser, 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:
The tapes (or diskettes) you need to restore from
The raw device name on which you want to restore the file system
The type of tape device you will use
The device name (local or remote) for the tape device
Determining the File System Name
If you have properly labeled your backup tapes, you should be able
to use the file system name (/dev/rdsk/device-name) from the tape label. For more
information, see How to Find File System Names.
Determining the Type of Tape Device You Need
You must use a tape device that is compatible with the backup
media to restore the files. The format of the backup media determines which
drive you must use to restore files. For example, if your backup media
is 8-mm tape, you must use an 8-mm tape device to restore the
Determining the Tape Device Name
You might have specified the tape device name (/dev/rmt/n) as part of
the backup tape label information. If you are using the same drive to
restore a backup tape, you can use the device name from the label.
For more information on media devices and device names, see Chapter 30, Managing Tape Drives (Tasks).
