Azure Blob Storage

1. Set up the storage

1. In the Azure portal, create a Storage account (or use an existing one).
2. Inside it, open Containers and create a new private container.
3. Open Security + networking > Access keys and copy the Storage account name and one of the Keys.

2. Connect it in Nyx Backup

New backup set > destination Azure Blob Storage, then enter:

• Account name - the storage account name.
• Container - the container you created.
• Account key - from step 3.
• Access tier (optional) - leave as the default, or pick a cheaper cold tier. See Cold storage tiers below.

Once Test connection succeeds, set a schedule and retention, save the set, and choose Run now. Nyx Backup encrypts everything on your machine before upload, so this destination only ever holds encrypted blobs. Give each machine its own bucket or folder - see Connecting storage.

Cold storage tiers

Azure Blob offers cheaper tiers in the Access tier field:

• Cool and Cold - cheaper to store, read immediately, with a per-GB retrieval fee and a minimum storage duration (30 days for Cool, 90 for Cold).
• Archive - cheapest, but objects are offline and must be rehydrated before a restore. Nyx Backup requests the rehydration and waits for it, then downloads. Rehydration takes time (up to several hours) and Azure charges a retrieval fee.

Because of the minimum storage duration, cold tiers suit archives you keep and rarely restore, not fast-changing folders.
