Configuring Veeam Backup & Nextcloud External Storage with Sovereign Indian S3 Buckets

For Indian IT infrastructure managers, system integrators, and Managed Service Providers (MSPs), protecting corporate VMware/Hyper-V virtual machines and private collaborative file stores is a top operational priority.

Two enterprise open-standard platforms dominate this space:

1. Veeam Backup & Replication: The gold standard for enterprise virtual machine, Windows Server, and Linux physical server disaster recovery.
2. Nextcloud Hub: The leading self-hosted private cloud productivity platform for Indian enterprises and government agencies seeking to avoid public cloud vendor lock-in.

Both platforms support S3-compatible object storage as their primary or secondary capacity tier. However, backing up multi-terabyte virtual disk images (.vbk, .vib) or archiving sensitive internal documents to overseas US/EU cloud buckets violates Indian data residency norms (such as the DPDP Act 2023 and RBI directives) while incurring exorbitant dollar-denominated egress and storage fees.

In this guide, we provide a hands-on tutorial for configuring Veeam Scale-Out Backup Repositories (SOBR) and Nextcloud External Storage with QuixiCloud M-S3 sovereign Indian buckets.

Part 1: Configuring Veeam Backup & Replication with QuixiCloud M-S3

Veeam utilizes S3 object storage within its Scale-Out Backup Repository (SOBR) architecture as the "Capacity Tier" for automated, policy-based offsite tiering and ransomware-proof immutability.

Step 1: Add New Object Storage Repository in Veeam

1. Open the Veeam Backup & Replication Console.
2. Navigate to Backup Infrastructure > Backup Repositories > Click Add Repository.
3. Select Object Storage > Choose S3 Compatible.
4. Enter a name for the repository (e.g., QuixiCloud-Mumbai-S3-Vault).

Step 2: Configure Service Point & Credentials

• Service Point: https://s3.quixicloud.com
• Region: in-west-1
• Credentials: Click Add and enter your QuixiCloud Access Key and Secret Key.

Step 3: Select Bucket and Enable Immutability

1. Veeam will connect to QuixiCloud and display your available buckets. Select your designated backup bucket (e.g., veeam-enterprise-backups).
2. Create or select a target folder.
3. Enable Immutability (WORM): Check the box:
   Make recent backups immutable for [30] days.
   • QuixiCloud’s S3 Object Lock compliance engine ensures that even if local administrative credentials are compromised by a ransomware attacker, the offsite backups in QuixiCloud cannot be deleted or encrypted during this retention window.

Part 2: Integrating Nextcloud with QuixiCloud Sovereign S3 Storage

Nextcloud can utilize QuixiCloud M-S3 in two primary configurations:

1. Primary Object Storage: Replacing the local server disk entirely, allowing Nextcloud to scale to petabytes with zero storage management overhead.
2. External Storage App: Mounting specific S3 buckets as collaborative project shares for specific departments or user groups.

Method A: Mounting S3 as External Storage (Quickest Setup)

1. Log into your Nextcloud instance as an Administrator.
2. Go to Apps > Enable the External Storage Support app.
3. Navigate to Administration Settings > External Storage.
4. Click Add Storage > Select Amazon S3:
   • Configuration:
     • Bucket: nextcloud-department-shares
     • Hostname: s3.quixicloud.com
     • Port: 443
     • Region: in-west-1
     • Enable SSL: Checked (True)
     • Enable Path Style: Checked (True)
     • Access Key: Your QuixiCloud Key
     • Secret Key: Your QuixiCloud Secret
5. Click the green checkmark. A green indicator verifies that your sovereign Indian S3 bucket is mounted and accessible to your Nextcloud users!

Method B: Nextcloud Primary Object Storage (config.php)

To configure Nextcloud to use QuixiCloud M-S3 as its primary data store, add the following objectstore block to nextcloud/config/config.php:

'objectstore' => [
    'class' => '\\OC\\Files\\ObjectStore\\S3',
    'arguments' => [
        'bucket' => 'nextcloud-primary-vault',
        'autocreate' => false,
        'key'    => 'YOUR_QUIXICLOUD_ACCESS_KEY',
        'secret' => 'YOUR_QUIXICLOUD_SECRET_KEY',
        'hostname' => 's3.quixicloud.com',
        'port' => 443,
        'use_ssl' => true,
        'region' => 'in-west-1',
        'use_path_style' => true,
    ],
],
