Copy an EOS Bucket to Another E2E Account

Object storage buckets cannot be directly transferred between accounts. This guide walks through migrating objects from a bucket in one E2E account to a bucket in another using the MinIO CLI (mc).

Step 1: Create a Destination Bucket​

In your destination E2E account, create a new bucket to receive the copied data.

  1. Click + Add Bucket on the Manage Object Storage page and enter a unique bucket name.
  2. Click Create.

Step 2: Attach Admin Access Keys to Both Buckets​

You need bucket admin access keys for both the source bucket (in the old account) and the destination bucket (in the new account).

For each bucket:

  1. Select the bucket and go to the Permissions tab.
  2. Click Attach Access Key.
  3. Generate a new key or select an existing one with Bucket Admin role.

The secret key is shown only once. Copy and store it before closing the dialog.

Step 3: Install the MinIO Client (mc)​

On your Linux server, download and install mc:

wget https://dl.min.io/client/mc/release/linux-amd64/mc
chmod +x mc
mv mc /usr/local/bin

Verify the installation:

mc --help

Step 4: Configure Both Buckets as mc Aliases​

Add an alias for each bucket using the access keys from Step 2. Replace the placeholder values with your actual keys.

# Destination bucket (new account)
mc config host add <destination-alias> https://objectstore.e2enetworks.net <ACCESS_KEY> <SECRET_KEY>

# Source bucket (old account)
mc config host add <source-alias> https://objectstore.e2enetworks.net <ACCESS_KEY> <SECRET_KEY>

Example:

mc config host add new-account-key https://objectstore.e2enetworks.net AKIAIOSFODNN7EXAMPLE wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
mc config host add old-account-key https://objectstore.e2enetworks.net AKIAI44QH8DHBEXAMPLE je7MtGbClwBF/2Sy99Eh4R9N0EXAMPLEKEY

Step 5: Copy Data from Source to Destination​

mc cp --recursive <source-alias>/<source-bucket> <destination-alias>/<destination-bucket>

Example:

mc cp --recursive old-account-key/my-old-bucket new-account-key/my-new-bucket

The --recursive flag copies all objects including those in subdirectory prefixes. Once the copy completes, verify the object count in the destination bucket matches the source.
