Backup file

Backup file
 

I've seen three different translations of "backup file," used in the context of computer software:


el archivo de backup
el archivo de respaldo
el archivo de copia de seguridad


Which is the most accepted translation? Is it different based on location (Spain vs. Latin America)?

It isn't necessary to include 'el archivo de.'

Each of the terms below appear in various websites, and I believe they'll be understood by computer users just about everywhere. I've listed them in order of number of hits returned in Google.
copia de seguridad
copia de reserva
copia de respaldo
respaldo
backup

I agree with Rusty and with "archivo de respaldo". It may change from region to region and probably it also changes with context. :)
