With keyfile and blake2 algorithm(Key stored in ~/.config/blake/)

borg init -e keyfile-blake2 REPO

borg create --stats --progress -C zlib,9 /path/to/repo::{hostname}-{user}-{now:%Y-%m-%dT%H:%M:%S} [PATH...]

borg create --stats --progress -C auto,zlib,6 [BACKUP-FOLDER]::usb-full-backup-{now:%Y-%m-%dT%H:%M:%S} [FOLDER-TO-BE-BACKED-UP]
borg init --encryption=none .
borg init --compression=none .

In combination with deja-vu:

borg create --stats --progress -C auto,zlib,6 [BACKUP-FOLDER]::{hostname}-{user}-{now:%Y-%m-%dT%H:%M:%S} [FOLDER-TO-BE-BACKED-UP] && deja-dup --backup && notify-send -t 1000 "Backup ready"

without -C compression option the lowest default is used.
