In case of cron job that creates an archive with a constant name will the archive be replaced with new one on the next cron job or terminated as the file with this name is already exists?

Cron just run your command, so it's up to you how this command may look. For example:

0 8 * * * rm -rf arc.zip && zip -r arc.zip /tmp

This cron runs every day at 8am and performs next steps:

  1. remove file arc.zip
  2. create new archive arc.zip from /tmp directory

There's no magic in cron - it just runs a program at a given timing. If that program has the logic to check if the archive exists, it will still have it when run via as a cron job. If it just overwrites the archive, it will continue doing so when run as a cron jbo.
