Slide 13
Backing up databases
v Regular backups should be kept for use
in case of accidents, i.e. hardware crash,
programme corruption etc.
v Backups can be kept in diskettes or in a
different directory of the same PC.
v If the database is too big to be copied
to one diskette it can be compressed and
copied to many diskettes using Winzip
v Database can also be copied to a CD if
you have a CD writer.

Note
How often you need to take backups depends on the rate of
additions/ alterations to the database.
You must remember that in case of any hardware/software
corruption you will lose all your data since the last backup.
If there are many databases with a large number of records
it is better to have backups on a Re-writable CD
