Support for Restoring AWS Deployment from Snapshot

[emrgnt-cmplxty]

Describe the problem

I experienced an issue where their EC2 instance went down for unspecified reasons and needed guidance on how to bring back up the Chroma environment. I took a snapshot of the attached volume and am interested in restoring the AWS deployment using this snapshot.

Context:

• The user utilized Chroma version 0.4.12.
• A snapshot was taken of the volume attached to the instance.
• The user tried using terraform apply -target=aws_instance.chroma_instance to bring down and back up the EC2 without destroying the attached volume.
• The user mentioned facing challenges and is looking for a more efficient solution for re-deployment using the snapshot.

Describe the proposed solution

Requirements:

Feature for Snapshot-based Restoration:

• Add support for restoring AWS deployment from a snapshot, specifically allowing the use of a snapshot ID to base the volume on.
• Disable the formatting of the volume during this restoration.

Documentation & Guide:

• Provide comprehensive documentation or a guide to facilitate users in restoring the service back online using snapshots.
