Tape Backup: Is it Obsolete?
Tape backup software is today becoming an
obsolete technology as newer backup software solutions are
replacing the traditional tape backup software systems. Tape
backup is usually used by larger corporations such as banks and
financial firms that depend on the resilience of tape backup and
tape backup software. Tape backups are much more dependable than
normal backups as data is written on a physical tape (floppy or
cassette) that can be stored and later retrieved when needed.
There are, however, disadvantages of tape backup
software and these include: it can be very time consuming to
make a backup and to retrieve the data, it is monetary expensive
to make a backup, and much needed storage is required to store
the tape backups. For those companies that require long term
backed up data, then tape backup software is the solution to
their backup needs.
Today's market demands low price software and hardware, fast access and backup times, and convenient restore options. In all these points tape backup is unfortunately unattractive. First, the hardware to read and write tapes isn't standardized. Second, tapes are not standardized: they require special devices and software. Tapes needs to be rewound so they don't provide random access, unlike USB flash drives and regular hard drives.
Another interesting shift in market trends is that information is becoming increasingly short-lived. Data does not need to be kept forever. Usually the "life expectancy" of information is just a couple of years in most industries, after which information is becoming obsolete and redundant.
Apart from very few extremely critical applications, tape backup technology is simply not keeping up with the times. The cost per GB, the cost of maintenance, and the inconvenient handling make tape backup an outdated technology which is only suitable in small niches who can afford it.
