Backups are not as cool as pentesting, but boy do they matter when things go sideways. This week I\u2019m sharing how a Proxmox backup disk space meltdown led me to a completely overhauled \u2014 and honestly pretty bulletproof \u2014 backup setup for both home and work. Claude played a big role in helping me sort it all out. Here\u2019s what we get into: The backup history tour \u2014 I\u2019ve been through CrashPlan, Dropbox, Backblaze (which saved my bacon after my house fire in 2019!), and a mystery one that may or may not have had \u201cPanda\u201d in the name. These days I\u2019m settled on ARQ for personal backups \u2014 dead simple, backs up to just about everything (Dropbox, OneDrive, Google Drive, even their own ARQ Cloud for ~$80\/year), and all data is encrypted at rest. Not a sponsor, but they should be. The 3-2-1 rule \u2014 I actually asked Siri mid-episode, and she initially thought it was a grounding\/anxiety technique. (Valid, I guess?) The real answer: three copies, two different media, one offline. I\u2019ve got a local copy plus OneDrive, Google Drive, and Dropbox \u2014 so I think I\u2019m covered. The work side: Proxmox + PBS \u2014 My \u201cdata center\u201d is a beefy Hetzner Proxmox box with about a dozen VMs. I had Proxmox Backup Server (PBS) set up on a secondary Hetzner box, happily cranking away\u2026 until it ran out of disk space and started yelling at me every night. Claude to the rescue \u2014 I spun up a Claude project, fed it terminal output and retention configs, and it gave me a straight-up honest assessment: either gut your retention policy (risky) or get more disk. It then walked me through Hetzner\u2019s auctions page \u2014 which I didn\u2019t even know existed \u2014 to find a storage-heavy, low-horsepower box. Ended up with two mirrored 8TB drives plus a 14TB drive for around $40\/month. Not cheap, but totally worth it as a business expense. The new setup \u2014 PBS is now on its own dedicated Hetzner box. VMs from both my data center and my home NUC Proxmox box back up there nightly. Claude also suggested using that 14TB drive as an SFTP target for ARQ, giving me yet another redundant copy of all my personal data. It\u2019ll take a few weeks to fully sync, but I\u2019m running some flavor of the 4-3-2-1 rule now (I made that up). Proxmox forever \u2014 Someone wrote in asking if I\u2019d go back to ESXi now that Broadcom brought back the free version. Hard no. I\u2019ve fallen in love with Proxmox and I\u2019m not going back. 7MinSec wiki scripts repo \u2014 Head over to 7MinSec.wiki and click the Scripts button to find a new GitHub repo where I\u2019m publishing pentesting scripts. First one up: a push-button Exegol installer. More to come \u2014 and I\u2019ll probably tease new scripts first over at 7MinSec.club on TuesdayTOOLSday!
