{Synology Glacier Backup App} Is it possible to move a S3 Vault to Glacier deep archive?

To archive approximately 11TB of data using the Synology Glacier Backup app and transition that data to Amazon S3 Glacier Deep Archive, you need to follow specific steps, given that direct support for Glacier Deep Archive is not available in the Synology Glacier Backup app

Overview of the Process

1. Backup to Amazon S3 Glacier: Use the Synology Glacier Backup app to initially back up your data to Amazon S3 Glacier.

2. Transition to Glacier Deep Archive: Set up an S3 bucket and configure lifecycle rules to transition your data from S3 Glacier to Glacier Deep Archive.

Steps to Achieve Your Goal

Step 1: Backup Data to Amazon S3 Glacier

1. Log into Your Synology NAS:

   • Access your NAS interface.

2. Install the Glacier Backup App:

   • Go to the Package Center and search for "Glacier Backup" to install it.

3. Create a Backup Task:

   • Open the Glacier Backup app.
   • Click on Backup > Actions > Create.
   • Follow the wizard:
     • Name your backup task.
     • Enter your AWS Access Key and Secret Key.
     • Select the AWS region where your Glacier vault is located.
     • Choose the shared folders you want to back up.
     • Set a backup schedule (consider running it fully once and then incrementally).

4. Start the Backup:

   • Review your settings and click Done to initiate the backup process.

Step 2: Set Up an S3 Bucket for Lifecycle Management

1. Create an S3 Bucket:

   • Log into your AWS Management Console.
   • Navigate to S3 and create a new bucket (ensure it’s in the same region as your Glacier vault).

2. Configure Lifecycle Rules:

   • Go to the bucket properties and select "Lifecycle rules".
   • Create a new rule that transitions objects from S3 Glacier storage class to Glacier Deep Archive after a specified number of days (e.g., immediately after upload or after a set period).

Step 3: Transition Data from S3 Glacier to Deep Archive

• Once your data is in S3 Glacier, it will automatically transition according to the lifecycle rules you set up. This process is managed by AWS, and you will incur costs based on the number of transitions and storage duration.

Important Considerations

• Direct Support Limitations: The Synology Glacier Backup app does not support direct uploads to Glacier Deep Archive, meaning you must first back up to S3 Glacier before transitioning.

• Costs: Be aware of costs associated with transitions between storage classes, especially if you have many small files, as these can accumulate charges.

• Data Retrieval Times: Understand that retrieving data from both S3 Glacier and Deep Archive can take several hours, so plan accordingly if you need access.
