Backup Strategy
Data is sometimes lost by a user either accidentally
removing or overwriting a file or misusing a command.
A power failure could corrupt data or cause a hard disk
crash.

be avoided.
NOTE
Data can be restored if you follow proper backup
strategies – one of the most important responsibilities of
the system administrator is to implement a solid backup
strategy.
The backup strategy you use to protect from data loss
depends on a number of variables such as:
■
How heavily is the system used?
■
How often does the data change?
■
How critical is it that files can be restored
quickly?

to obtain an Agilent SE could be avoided
if you maintain a separate backup of the
/etc/bootptab and
/hp3070/diagnostics/th1/config files.
However, the need for a separate backup of these
two files should be eliminated by following a
practice of maintaining system recovery tapes for
your system(s); if you maintain system recovery
tapes, use of a disaster recovery tape should never
be necessary.
Introduction
Use of these instructions can be avoided by maintaining
system recovery tapes for your system(s).
A disaster recovery tape can be used to restore a system
when a system recovery tape is not available.
If a disaster recovery tape is used, you will be required
to re-establish both the /etc/bootptab and
/hp3070/diagnostics/th1/config files. If these two
files are not available (from a backup source), it will
likely be necessary to contact your Agilent systems
engineer (SE) to re-establish them.

Disaster-recovery tapes are available from Agilent.
They are manufactured to bring a 3070 system to a
specific working revision of 3070 software.
Use these instructions if a system recovery tape does not
exist AND either:
■
A system disaster has occurred such as a disk
crash OR

A replacement disk drive has been installed.

In the event of a disaster such as if the hard drive
crashes, the quickest way for recovery is through the use
of a system recovery tape.
However, the need for a separate backup of these
two files should be emiminated by following a
practice of maintaining system recovery tapes for

Use the system recovery tape:
■
To restore a system with a hardware failure on the

If the normal HP-UX system cannot boot.
NOTE
NOTE
The system recovery tape cannot be used to
recover individual files.
A disaster recovery tape can be used to restore a system

The process will take over an hour. You will see feedback on the display only if you
need to take some action. You will be notified of any files that are in use and
therefore backed up to another name.
NOTE
If you see the error:
grmd: Cannot write to the sockets directory
Then log in as root then enter:
chmod 777 /var/spool/sockets
The system should come up with a CDE login prompt.
