Restoring Your Data
Chapter 6 699
Examples of Restoring Data Remotely
Here are some examples of restoring data remotely (across the network):
• To use frecover to restore files across the network, enter:
frecover -r -vf remote-system: /dev/rmt/0m
• To use the tar command to restore files across the network, enter:
remsh remote-system -l user dd if=/dev/rmt/0m bs=7k \
| tar -xvf -
If the tar backup used relative paths, the files will be restored
relative to the current directory. If absolute paths were used, the files
will be restored to their original paths.
Recovering From a System Crash
IMPORTANT To protect your data, you should create a recovery system to be used in
the event of a system crash.
On 10.x systems See copyutil (1M) and the documentation accompanying your support
media for instructions on creating a recovery system. copyutil is only
available from the support media.
On 11.0 systems On 11.0 systems, you can create a customized System Install Image of an
existing system. To obtain the system recovery features and manpages,
install Ignite-UX from the Application Release CD-ROM and choose the
bundle that matches your release (for example Ignite-UX-11.0).
The following commands support system recovery:
• make_recovery - creates the System Recovery Image
• check_recovery - checks whether the System Recovery Image needs
to be recreated.
For detailed information, see the HP-UX installation and update guide
for your version of HP-UX.
