 The
Problem:
Backing up your data may seem like a simple thing to do. Making a
single backup copy of your hard disk drive, or some of your
important files actually is a very simple task. Planning and
implementing a backup strategy that will allow you to recover your
data when it is lost can be a more complex task. There are a lot of
factors that will determine the methods used to backup your data,
the frequency of the backups, the retention of previous backups, and
the storage of backup data.
Regardless of the backup method that is
used, the data has to be stored on some data storage medium
somewhere.
-
Magnetic tape
-
Magnetic tape has long been the most
commonly used medium for bulk data storage, backup, and archiving.
Tape has typically had an order of magnitude better capacity/price
ratio when compared to hard disk, but recently the ratios for tape
and hard disk have become a lot closer. There are myriad formats,
many of which are proprietary or specific to certain markets like
mainframes or a particular brand of personal computer.
Disadvantges:
higher costs compared to other storage medium, tape is
physically delicate and easily compromised by environmental factors
such as heat, humidity, and magnetic interference, tape cartridges
must be replaced frequently (every 6-12 months), and tape’s innate
sensitivity contributes to high failure rates. Backup and recovery
experts estimate that anywhere from 42 to 71 percent of tape
restores fail.
Hard disk
The capacity/price ratio of hard disk has been rapidly improving
for many years. This is making it more competitive with magnetic
tape as a bulk storage medium. The main advantages of hard disk
storage are low access times, availability, capacity and ease of
use. External disks can be connected via local interfaces like
SCSI, USB, FireWire, or eSATA, or via longer distance
technologies like Ethernet, iSCSI, or Fibre Channel.
Disadvantages: easily damaged, especially while
being transported (e.g., for off-site backups), and their
stability over periods of years is a relative unknown.
Optical disc
A recordable CD or DVD can be used as a backup device. One
advantage of CDs is that they can in theory be restored on any
machine with a CD-ROM drive. (In practice, writable CD-ROMs are
not always universally readable.) In addition, recordable CD's
and DVD's are relatively cheap. Many optical disk formats are
WORM type, which makes them useful for archival purposes since
the data can't be changed. Other rewritable formats can also be
utilized such as CD-RW or DVD-RAM. The newer HD-DVDs and Blu-ray
Discs dramatically increase the amount of data possible on a
single optical storage disk, though the hardware may be cost
prohibitive for many people.
Disadvantages:
easily damaged by scratching, easily lost or misplaced, and
the physical lifetime of the optical disk has become a concern
as it is possible for some optical disks to degrade and lose
data within a couple of years.
Solid state storage
Also known as flash memory, thumb drives,
USB flash drives, CompactFlash, SmartMedia, Memory Stick, Secure
Digital cards, etc., these devices offer excellent portability
and ease-of-use.
Disadvantages:
high cost per megabyte, and easily lost or misplaced.
Remote (OnLine) backup service
Backing up via the internet to a remote location can protect
against some worst-case scenarios such as fires, floods, or
earthquakes which would destroy any backups in the immediate
vicinity along with everything else.
Disadvantages:
internet connections (particularly
domestic broadband connections) are generally substantially
slower than the speed of local data storage devices,
and unless encrypted, loss or compromise of sensitive data is
possible.
