Shouldn't you copy the file to another drive?
- That would be Raid 2, a totally unnecessary amount of Raids

Technically that would mean that one copy of the file is no longer updated when the other is.

You should consider using ln bkp.tar.gz bkp2.tar.gz instead.
- loop { rsync -tu bkp.tar.gz bkp2.tar.gz rsync -tu bkp2.tar.gz bkp.tar.gz }
- that just keeps the data in one physical location though

Btrfs:

sudo btrfs -m raid1 -d raid1 /dev/sda1 /dev/sdb1

ZFS:

zpool create mypool mirror /dev/sda /dev/sdb

This isn't even meme, this is exactly how it is. I run this script once a day on my Raspberry Pi NAS:

rsync -va /media/pi5tb/ /media/pi5tb_backup/
