I would suggest you open the backup directory table and append the data from current.

This can avoid the filename, both already exist.
and you can also backup even the file is in use by other user.

For example,
use backThu\myTable IN 0 ALIAS BkMyTable EXCL
SELECT BkMyTable
ZAP
APPEND FROM MyTable
USE in BkMyTable

Although The backup time would be longer, it would ensure the data is copied.
There maybe some unexpected error such as original data file corrupted.
COPY FILE will fail but append data from it works.
