You cannot natively back up Spaces buckets on DigitalOcean, but you can use one of the following methods:
Create a new bucket on another team and transfer files using rclone or a similar tool. For detailed steps, see our tutorial on transferring buckets with rclone.
Use a tool like s3cmd to download the files and save them in a local repository. For detailed steps, see our tutorial on setting up s3cmd with Spaces. Once you finish setup, you can download a bucket’s files recursively with the s3cmd command s3cmd sync s3://your_bucket_name/folder /destination/folder.
Set up backups with SnapShooter to keep the contents of a bucket synced to another bucket. You can use the S3 sync backup job after setting up Spaces as your SnapShooter storage provider.
Set up a tool like GoodSync to automatically back up and sync files.
