Tusky offers an optional centralized backup service that stores copies of your files in a traditional blobstore alongside Walrus. This provides an additional layer of insurance against data loss — your files exist on both the decentralized Walrus network and a reliable centralized backup.

​
Why Backup?

The Walrus network is designed for durability through redundant encoding across storage nodes. However, some use cases demand an extra safety net:

Redundancy

A second copy in a centralized blobstore protects against edge cases where Walrus data might become temporarily unavailable.

Faster Recovery

In disaster recovery scenarios, restoring from a centralized backup can be faster than reconstructing from the decentralized network.

Compliance

Some regulatory environments require data to be stored in identifiable, auditable infrastructure in addition to decentralized systems.

Peace of Mind

For mission-critical data, a backup in a proven centralized system provides additional confidence.

​
How It Works

1

Enable backup on an environment

Turn on backup for any environment through the dashboard or API. Backup is configured per environment — you can choose which environments need the extra protection.
2

Automatic on upload

Once enabled, every file uploaded to the environment is automatically copied to Tusky’s centralized blobstore in addition to being published to Walrus.
3

Transparent access

File retrieval works exactly the same whether backup is enabled or not. If the primary Walrus path is unavailable, the aggregator can fall back to the backup copy.

​
Enabling Backup

Navigate to your environment’s Settings → Backup and toggle Enable Backup. All future uploads to this environment will be backed up automatically.

​
Pricing

Backup is a paid feature with a per-GB monthly cost on top of your standard Walrus storage fees. The backup fee covers:
  • Storage in the centralized blobstore
  • Data transfer to and from the backup
  • Automatic lifecycle management
Backup pricing is separate from Walrus storage costs and the Tusky platform fee. Check the dashboard for current rates.

What Gets Backed Up

For encrypted environments, the backup stores the encrypted file content. Tusky never has access to your unencrypted data, even in the backup.

​
Disabling Backup

You can disable backup at any time:
  • New uploads will no longer be backed up.
  • Existing backup copies are retained for the remainder of the current billing period and then deleted.
Disabling backup does not immediately delete existing backup copies. They are retained until the end of the billing period. After that, only the Walrus copies remain.
