Minimal Influx Backup

I ran the backup command for my DB and it created the backup folder. I now have large files in the folder that look like this:

20200815T015240Z.s240.tar.gz

There are also corresponding files with a similar label, different extention:

my_database.autogen.00240.00

Are one of these files redundant? If I delete these autogen files will I be able to restore the DB?

What if I had just one of these daily files and nothing else - Can I restore from that?

Thanks!
