AWS EC2 Snapshot Script

This PowerShell script automates the creation of snapshots for AWS EC2 volumes. It allows users to create snapshots either for a specific volume or for all volumes attached to an EC2 instance identified by its private IP address.

Features

• Create snapshots for a specific volume by providing the Volume ID.
• Create snapshots for all volumes attached to an EC2 instance by providing the Instance IP.
• Monitors the progress of each snapshot until completion.
• Copies tags from the EC2 instance to the snapshot.
• Adds a user-defined Name tag to each snapshot.
• Displays a clear summary of all snapshots created.

Usage

Prerequisites

1. AWS Tools for PowerShell must be installed.

   Install-Module -Name AWS.Tools.EC2 -Scope CurrentUser

2. AWS credentials must be configured.

   Initialize-AWSDefaultConfiguration -ProfileName <ProfileName> -Region <Region>

Script Parameters

• -InstanceIP (optional): Private IP address of the EC2 instance whose volumes you want to snapshot.
• -VolumeId (optional): Volume ID of the specific volume you want to snapshot.
• -SnapshotName (required): The name to assign to the snapshot.
• -Description (required): Description for the snapshot.

Examples

1. Create Snapshot for a Specific Volume

.\CreateSnapshot.ps1 -VolumeId "vol-03e50165686709bbc" -SnapshotName "MySnapshot" -Description "Snapshot for a single volume"

2. Create Snapshots for All Volumes Attached to an Instance

.\CreateSnapshot.ps1 -InstanceIP "10.0.0.10" -SnapshotName "MySnapshot" -Description "Snapshots for all attached volumes"

Output

Example Output

Snapshot Summary:
Volume ID: vol-07cdd2216ade2b772 | Snapshot ID: snap-0f015a23860b1e308 | Status: Completed
Volume ID: vol-08a167d06b7d90f4d | Snapshot ID: snap-092d83879d80c9946 | Status: Completed

Notes

• If both -InstanceIP and -VolumeId are provided, the script prioritizes -VolumeId.
• Proper error handling ensures that failed snapshots are reported in the summary.
• Make sure the IAM role or user associated with your credentials has permissions for ec2:DescribeInstances, ec2:CreateSnapshot, and ec2:CreateTags.
