Importing Large AWS EC2 Instances

Importing AWS EC2 instances with disks over 500GB can start to reach limitations in AWS.

If possible, acquire these systems using the "Triage" option if SSM is enabled. Alternatively, you can use another option such as SSH or AWS EC2 Connect where available (select the instance in the AWS console, then select "Actions" > "Connect") to acquire with Cado Host.

To speed up the importing of very large instances via the normal Volume acquisition method, we recommend:

  • Creating a Snapshot of the disk, then enabling Fast Snapshot Restore on it. You will need to wait for up to an hour for the Fast Snapshot Restore to be enabled, then you can import the Snapshot (snap-xxx).
  • Another option is to change the instance type of the target system to a larger system. When acquiring, we match the instance type of the target system for compatability. Larger instances can have higher disk, network and CPU limits.
