The guide covers why local-only backups are insufficient, walks through the Backblaze bucket and Application Key setup, and shows how to configure PBS to use S3 as a datastore. The author also notes the cost trade-offs versus a self-hosted 3-2-1 pipeline for large or sensitive workloads. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I configure Proxmox Backup Server to use a Backblaze S3 bucket as a datastore? Create a bucket on Backblaze with an application key set to allow access to all buckets, then in Proxmox Backup Server's S3 Endpoint tab enter the Backblaze bucket's endpoint IP, use the KeyID and Application Key as the Access and Secret Keys, and enable the Path Style and Skip-If-None-Match header options before adding an S3-type datastore pointing to that bucket. _Homelabbers wiring up offsite Proxmox backups can compare setup notes and tooling on daily.dev._ ### Why would someone still keep a self-hosted remote backup pipeline instead of only using S3 for Proxmox Backup Server snapshots? Cost and confidentiality: backing up several terabytes of virtual guests weekly, with recoveries happening a few times a month, adds up to significantly more expense on cloud storage than a self-hosted 3-2-1 pipeline built from repurposed old hardware, and confidential dev VM data is better kept off third-party cloud platforms entirely. _Anyone weighing cloud versus self-hosted backups for Proxmox VMs can track cost tradeoffs like this on daily.dev._ ## Similar posts on daily.dev -
