Backup strategies
System hangs and hard disk problems are hazards even with the most
reliable computer systems, including your SPARCbook. Problems may
be caused by operator error or by software or hardware failures.
However reliable the software and hardware is, there is always a risk
that you may lose valuable data. In the case of your SPARCbook, the
hard disk can be removed very easily giving rise to the additional risks
of losing or damaging a disk while it is not fitted in the system. For
these reasons, it is vital to maintain regular backups of your work and
of essential system configuration files.
SPARCbook usage and filesystem structures vary widely from system
to systems, which means that your backup strategy must be appropriate
for your individual needs. You should consult the system administrator
for your organization who will be able to advise you on the best
strategy for you and the facilities available. The following observations
may help in devising your strategy.
•
Your SP ARCbook runs the standard Solaris operating system
with backup capabilities identical to those of a conventional
desktop system, including
tar, cpio
and
ufsdump.
•
The preloaded operating system is supplied on a CD-ROM and
can be re-installed very easily. The installation process
automatically configures your hard disk for you but provides no
protection for work or applications directories.
•
Consider also how cumbersome different media and drives are
to carry around with your SP ARCbook and whether you are able
to power any external drives in a different country. The Tadpole
removable hard disk adapter and Tadpole SCSI floppy disk drive
provide light-weight options that are powered by your
SPARCbook.
