Just upgrade the day before yesterday from 23 to 25 with a lot of truechart apps the TrueNAS apps were an absolute breeze. Truecharts not so much. The biggest part of preparing is the backup as you won’t be able to access your kubernetes config after the update so get the deployment files as yaml and don’t forget that you might need more like ingress rules or kubernetes secrets (looking at you homarr)

He can’t open ports because of the ISPs setup.

That’s why I initially got them to reorganize my raid setup and have them as backups in case I need them. So I’m using lto4 which is 800gb per tape (current standard is lto9 16TB per tape) And it really depends on how cheap you can get the drive for me I got a tape drive for like 200€ and bought bunch of tapes ~50 for 6€ per tape if you can get a LTO5 drive for a similar price you would only need half the amount of tapes. So all in for me it was 500€ but you can definitely buy less tapes if you don’t need that many all at once. For your 30tb that would be 228€ in tapes.

It was great fun researching the topic and comparing different eBay listings for hours 😅

Currently doing a full backup of 37TB to tape. Which I would normally do once per quarter but I got a smart error on one of my drive that I’ll have to replace but before shutting down and removing the drive I want to have a full backup I might even get warranty on the drive at least I got the last time this happened drive has lower then 200 days of runtime. We’ll see

If you’re talking multiple Terrabytes and are located in the EU you might want to consider AWS Glacier I have like 6Tb on there and pay sub 20€ p.m. If you’re in the EU you can request one free migration download by contacting the support. Otherwise you’ll pay thousands.

My whole setup including 2 PIs and one fully speced out AM4 system with 100TB of drives a Intel Arc and 4x 32gb ecc ram uses between 280W - 420W I live in Germany and pay 25ct per KWh and my whole apartment uses 600w at any given time and approximately 15kwh per day 😭

stroj task runs daily the initial sync took forever tho because I only have 5MB UP connection

I’ve got the PR1500ELCDRT2U in my storage room and when it is just passing through mains then it is completely silent once it’s ether charging or running of the batterys than the fan kicks in but that’s it

so most of the time if your ISP goes down power is also out so cellular service might also fail because ether the power outage or high usage by useres using it as backup maybe Starlink? as it’s not affected by your local power grid

my 20 TB storage is currently hosted by Hetzner on a SMB Share with a acompanying server The storage is accessable via NFS/SMB i have a Windows 10 VPS running Backblaze Personal Backup for 7$/Month with unlimited storage while mounting the SMB share as a “Physical Drive” using Dokan because Backblaze B1 doesn’t allow backing up Network shares If your Storage is local you can use the win Backup Agent in a Docker container

I’m currently backing up my 20TB Hetzner Storage box using a windows VM to Backblaze Personal backup. I’m using https://github.com/dokan-dev/dokany to mount the SMB share as a “real” local drive.
