+# Backblaze B2
+
+## Overview
+
+S3-compatible cloud storage for off-site backups of critical homelab data. Configured as a Cold storage tier in TrueNAS and as a rclone remote for Obsidian vault sync.
+
+## Key Facts
+
+- **Service**: Backblaze B2 (S3-compatible)
+- **Purpose**: Off-site backup of configuration, documents, and selected data
+- **Cost**: ~$7/mo
+- **TrueNAS integration**: B2 bucket configured as Cold storage tier in TrueNAS SCALE
+- **Obsidian vault sync**: rclone remote `b2-homelab-backups` syncs vault to B2 bucket
+- **Access**: Application key-based authentication (not AWS credentials)
+
+## TrueNAS Configuration
+
+TrueNAS exports `backblaze-b2` remote as a Cloud Sync channel. Datasets backed up include:
+- Obsidian vault snapshots
