Copying zip failed because: File already exists at path

[sutcliffe121]

Problem:
Running php artisan backup:run gives the following error:
Copying zip failed because: File already exists at path: CJS-Web/NEW2021-03-21-12-11-08.zip.

My Setup:
I am trying this locally with a Laravel 8 site and I am trying to get the back up to save to a Digital Ocean Space by setting up a new file system using the S3 driver.

My config/backup.php:
/*
* The disk names on which the backups will be stored.
*/
'disks' => [
'public', 'do'
],

My config/filesystems.php:
'do' => [
'driver' => 's3',
'key' => env('DO_ACCESS_KEY_ID'),
'secret' => env('DO_SECRET_ACCESS_KEY'),
'region' => env('DO_DEFAULT_REGION'),
'bucket' => env('DO_BUCKET'),
'endpoint' => env('DO_ENDPOINT'),
'url' => env('DO_URL'),
],

My .env:
FILESYSTEM_DRIVER=do

DO_ACCESS_KEY_ID=removed
DO_SECRET_ACCESS_KEY=removed*
DO_ENDPOINT=https://fra1.digitaloceanspaces.com
DO_DEFAULT_REGION=FRA1
DO_BUCKET=removed
DO_URL=https://removed.fra1.cdn.digitaloceanspaces.com

Output from back up failed email:
Whoops!

Resolved. It was due to an incorrect setup of the Digital Ocean Spaces filesystem: https://stackoverflow.com/questions/66725041/using-aws-s3-v3-with-laravel-and-digitalocean-spaces-results-in-error-501-not-im
