VERIFYING A BACKUP

Once you have performed a backup, you may like to verify it to check that everything has
backed up correctly. This is done by pressing the VERIFY key followed by EXECUTE. You
will see this screen:
You should press EXECUTE to continue, EXIT to abort. As the verification takes place,
you will see this screen:
You may abort the process at any time by pressing the EXIT key.
NOTE: The VERIFY process does a comparison of what is on the source disk and what is
on tape and the idea is that the disk contents and the tape contents must be identical for
the verification to be successful. Because of this, the VERIFY process is best done
immediately after a backup. In this case, you should have no problems as the two media
should have identical contents. If, however, you make a new recording on the source disk
or delete anything from the source disk after the backup, the contents of both media will
not be the same and so you will receive messages such as "FILE XXXX MATCH NOT
FOUND". This is telling you that either it has found something on the disk which does not
correspond to what is on tape (i.e. you may have made a new recording) or it has found
something on tape which it cannot find on the disk (i.e. you have maybe deleted
something off disk).
It is not essential that you run the VERIFY process after a backup but, bearing in mind the
potentially serious implications of a faulty backup, it is highly recommended. However, you
will please note that the VERIFY process will take about two or three times as long as the
backup took so whilst it's recommended you verify your backups, you might like to do it
during a 'quiet moment'.
