Before I start the question I will just state that I am no sysadmin, but a layman seeking help.

I'm using Linux 3.10.0-514.26.2.el7.x86\_64 and Amazon Web Services external backup service. In order for it to work I need a backup directory on my server, where all the files will be zipped, copied to and accessed from by the external backup service.

The question is - should I mount a separate partition on that directory? Backups can take a lot of HD space, and having a separate partition for this purpose should in theory secure my day-to-day server operations and websites from issues with low amount of free disk space.

But is it the right approach? Is there a better one?
