pyznap VS Vault

Sanoid/syncoids been mentioned but honestly for once a week learning by doing . Pyznap also excellent when you want to automate. https://github.com/yboetz/pyznap

In contrast, zfs snapshots are immutable, and thus anything short of a hardware failure can be addressed with a simple zfs rollback command. This includes deliberate, accidental, and malicious actions. They can also be automated (I personally use pyznap but syncoid is also quite popular), creating what is effectively an incremental backup. I maintain - for each dataset - 24 hourly, 7 daily, 6 monthly, and 1 yearly snapshot. Additionally, I have a wholly separate server that wakes up once a day to ingest these snapshots via zfs send/recv, so even if I made a horrible mistake or suffered a catastrophic hardware failure, I could completely restore from the other server. This last point brings snapshots firmly into the realm of backups, IMO.

Another favorite option is Pyznap, which is python based and originally created to have have a few features and changes compared to sanoid. The author is also active here on reddit. I and not sure what the differences are anymore, it'll come down to trying them and preference.

I have two Supermicro X9 2Us, each with Proxmox. One has allegedly existed solely as a backup target, which wakes up daily to ingest ZFS snapshots using pyznap. Unfortunately, for reasons which are unclear, this particular node doesn't always like to see its boot device, which is an NVMe drive. It's the exact same board as my primary, with the exact same modified BIOS to allow booting from NVMe. It usually takes 2-3 cycles before it'll see it and boot.

I have two nearly identical systems, both running Proxmox, with Debian VMs. One is a backup, which (once this is worked out) will wake up daily to ingest incremental backups. I'm using pyznap to handle the backup strategy.

HashiCorp Vault

For a more comprehensive and robust secret management solution, get your hands on tools like GCP Secret Manager, or HashiCorp Vault. They're like the security guards of your secrets, providing a safe house, access control, and keeping logs of who’s been snooping around.

HashiCorp Vault is a popular tool for managing secrets in Kubernetes clusters. It offers advanced features such as secure storage, encryption, dynamic secrets generation, and integration with Kubernetes through its Kubernetes authentication method.

So you've just bought a new platform tool? Maybe it's Hashicorp Vault? Snyk? Backstage? You’re excited about all of the developer experience, security and other benefits you're about to unleash on your company—right? But wait…

You seem to be looking for a cross-platform solution, and https://www.vaultproject.io/ provides just that. If everything was in AWS, AWS Secret Manager might be great, but imo Vault provides much better platform-agnostic capabilities.

> Refer to Build Certificate Authority (CA) in Vault with an offline Root for an example of using a root CA external to Vault.

Secret Management: Securely stores sensitive configuration data and secrets using tools like AWS Secrets Manager or HashiCorp Vault. Avoid hardcoding secrets in code or configuration files.

The author of this tool basically took the Shamir code from Hashicorp Vault, which is pretty mainstream. If you're looking for a solid implementation, I would start there[0]. I wouldn't use the Shamir code from this repo, as it's an old version of the vault code using field arithmetic that doesn't run in constant time.

Out of curiosity, what do you mean by this? cross-cluster? they already have HA: https://github.com/hashicorp/vault/blob/v1.14.1/website/cont...

while digging up that link, I also saw one named replication: https://github.com/hashicorp/vault/blob/v1.14.1/website/cont...
