With cloudHQ, you can set up a real-time backup of all your Dropbox Business accounts to Amazon S3, Amazon Glacier, or any other cloud storage service (Google Drive, etc.).

Real-time data backup will automatically make a backup copy of every change made to your Dropbox files. This means cloudHQ is essentially capturing every version of your Dropbox files and saving them to Amazon S3.

This insturctions will work also you want to backup your Drobpox to Box, Goole, Egnyte, etc.

It allows the Dropbox administrator to restore data (or create a snapshot of your system) to any point in time. You can think about cloudHQ sync as very powerful version of Apple Time Machine.

To set up real-time backup of Dropbox, you need to create backup sync pairs. Backup sync pairs define how cloudHQ will backup files for certain users. The backup sync pairs will back up each of your users’ Dropbox accounts to a dedicated folder. For example:

Dropbox (bob@acme.com)   -> Amazon S3/Backup_bucket/Dropbox (bob@acme.com)
Dropbox (alice@acme.com) -> Amazon S3/Backup_bucket/Dropbox (alice@acme.com)

...

And here are step-by-step instructions for how to achieve that:

Dropbox for Business Preparation:

• Ensure that you are a Dropbox for Business admin. Instructions are here: Dropbox for Business admin.

Amazon S3 Preparation:

Before we start the cloudHQ wizard to back up your Dropbox users, we first need to create an appropriate Amazon S3 bucket, Amazon AWS IAM user, and configure Amazon Glacier policies for your backup bucket (if needed).

• Create Amazon S3 bucket to store your Dropbox backups.
  If you are looking for Amazon S3 encrypted backups, then you will need to attach an AWS policy that will enforce AWS server-side encryption. The instructions are here: https://support.cloudhq.net/how-to-enforce-aws-server-side-encryption-on-your-amazon-backup-bucket/.
• Create an Amazon AWS IAM user to own this backup. Instructions are here: https://support.cloudhq.net/how-to-create-amazon-iam-user-for-cloudhq-sync-backup-to-amazon-s3/.
• Optionally, you can set up Amazon S3 to Amazon Glacier archiving rules. Instructions are here: https://support.cloudhq.net/how-to-setup-archive-to-amazon-glacier/.

Authorize cloudHQ to access your Amazon S3

In order to back up to Amazon S3, cloudHQ needs to be authorized to access your Amazon S3 bucket dedicated for backup.

To do that, you must provide a key ID and a secret access key of an IAM user with full read-write access to your backup bucket. If you don’t know what that is, please check here: https://support.cloudhq.net/how-to-figure-out-your-access-key-id-and-secret-key-in-amazon-s3/.
