Data Management

There are several considerations for managing data from the Cado platform

Controlling the lifecycle of data stored by the Cado platform

AWS supports this through Object Locks and Lifecycle Rules associated with your S3 bucket. Please see the AWS documentation for more details.

Azure supports this through Life Cycle Management Policies for your blob storage. Please see the Azure documentation for more details.

Storing sensitive customer data

Whether sensitive customer data is stored within the Cado platform is completely dependent on what data sources and evidence is imported into the software. In all cases, data is either stored within the database on the main Cado instance, within EFS, within a customers' S3 bucket or Azure storage. Since the Cado platform is deployed within the customers' cloud environment, the customer has control over the life cycle management of the data (example: using Life Cycle management policies) as well as who has access to potential sensitive data via VPC and Subnet rules.

Expanding available data storage within the Cado platform in AWS

Below are the steps for expanding the Cado data storage volume after deployment. This follows the steps as outline by AWS' documentation: Extend a Linux file system after resizing a volume


Before continuing, create a snapshot of the CadoResponseDataVolume volume which has the device name /dev/sdh. This will ensure you have a backup of the data volume to restore, in case you encounter an issue.

  1. Extend the /dev/sdh storage volume via the AWS Console by:
    • Navigating to your Cado instance
    • Click the Storage tab
    • Click on the volume instance ID for Device Name /dev/sdh
    • Select the CadoResponseDataVolume
    • Click Actions
    • Select Modify Volume
    • Enter the new volume size
    • Click Modify
  2. SSH into the Cado instance. example: ssh -i "us-east-2.pem"
  3. Run df -hT. Note the Avail space for the /dev/nvme1n1 filesystem mounted on /home/admin/data. This should display the old volume size.
  4. Run lsblk and note the nvme1n1 volume SIZE mounted on /home/admin/data. This should display the new volume size.
  5. To extend the volume and make it available to the OS, run sudo xfs_growfs -d /home/admin/data
  6. Run df -hT again and note the Avail space for the /dev/nvme1n1 filesystem mounted on /home/admin/data This should now display the new volume size.
