When I was setting up my own home lab a few years back, one of the things that kept me up at night was a simple question: what happens when important data disappears overnight? I learned the hard way that digital content — government statements, social media posts, official press releases — can vanish in hours with zero warning. After testing large-scale scraping pipelines in my rack across several archival projects, I know exactly what kind of hardware you need when urgency is real and the clock is ticking. The situation unfolding right now around the Hungarian election is a perfect case study in why every serious home labber should have a purpose-built archiving rig ready to go.
Key Takeaways
- Following Hungary’s April 2026 election, the DataHoarder community mobilized to archive social media content from officials who began deleting their online presence within hours of the result — a real-world stress test for home lab archiving rigs.
- A purpose-built archiving NAS needs at minimum 40TB of raw capacity, 10GbE networking, ECC RAM, and a ZFS-based OS like TrueNAS Scale to handle sustained write loads from parallel scraping jobs.
- The 3-2-1 backup rule (3 copies, 2 media types, 1 offsite) is non-negotiable for preservation work where data loss is irreversible.
- Hard drive selection matters enormously: CMR drives with 7200 RPM spindles outperform SMR drives for the random write patterns generated by web scrapers ingesting mixed media.
- Five NAS and storage products stand out in 2026 for this use case, ranging from a budget-friendly 4-bay entry point at around $300 to a prosumer 12-bay powerhouse capable of holding 240TB raw.
Why Hungary’s Election Made the DataHoarder Community Mobilize
On April 12th, 2026, Hungary held a landmark election in which the hungary voted 16year ruling FIDESZ party out of power — ending a political era that had fundamentally reshaped the country’s media landscape, judicial independence, and public institutions. Within hours of the results becoming clear, community members on r/DataHoarder began noticing something alarming: officials associated with the outgoing government were quietly deleting their social media footprints. One high-profile example involved a former cabinet minister whose entire Facebook page — years of posts, videos, official statements, and photos — disappeared completely before most people had even finished their morning coffee.
This is not a new phenomenon. Digital erasure is a well-documented response to political transitions, corporate scandals, and institutional accountability moments. The Internet Archive’s Wayback Machine captures only a fraction of what exists on platforms like Facebook, Instagram, and YouTube. Private social media content behind login walls is especially vulnerable. When a page owner hits delete, that content is gone unless someone with the right tools and the right hardware was already running a crawl.
The r/DataHoarder community rallied quickly. Within 24 hours, four volunteers had begun coordinated archival work. But the technical questions came flooding in: what tools should they use, how much storage do they need, and what NAS hardware can actually handle the sustained write loads of a parallel multi-site scraping operation? That is exactly what this guide answers.
For more context on how other community-driven archiving projects have handled massive datasets, our guide on how two students scraped, processed, and hosted an entire 354GB archive is essential reading for anyone new to this scale of data work.
What Large-Scale Web Archiving Actually Demands From Your Hardware
Storage Capacity Planning
In a real home lab setup, the biggest mistake beginners make is underestimating how fast storage fills during active scraping. A single politician’s Facebook page with a decade of activity — including HD video content — can easily reach 200GB to 400GB. Scale that to 50 or 100 public figures and affiliated media outlets, and you are looking at 10TB to 40TB of raw data before compression. Add in WARC files, metadata, checksums, and redundant copies, and the real storage requirement for a serious coordinated archival effort sits comfortably above 50TB.
The community consensus on r/homelab is clear: always build with at least 2x your estimated storage need. Scraping jobs produce unpredictable output sizes, especially when video is involved. A page you estimated at 50GB can balloon to 300GB once yt-dlp pulls down every embedded video at maximum quality.
Networking Requirements
Archiving pipelines are network-intensive on the ingest side and storage-intensive on the write side. Running 8 to 16 parallel scraper threads against Facebook, YouTube, and web archives simultaneously can push 200 to 400 Mbps of sustained inbound traffic. Your NAS needs 10GbE to avoid becoming the bottleneck. A 1GbE NAS will cap your effective write speed at around 112 MB/s theoretical — and real-world ZFS write performance on a busy array will be lower. 10GbE gives you headroom to run multiple scrapers without queuing writes.
CPU and RAM for ZFS
ZFS is the only filesystem worth using for long-term data preservation. It provides end-to-end checksumming, self-healing, and snapshot capabilities that traditional filesystems cannot match. However, ZFS is RAM-hungry. The rule of thumb is 1GB of ECC RAM per 1TB of storage, with a practical minimum of 16GB for any serious array. A TrueNAS Scale build running 8 drives will want 32GB of ECC RAM to keep the ARC cache effective and prevent data corruption during power events.

The Software Stack Every Archiving Home Lab Needs
Operating System
TrueNAS Scale is the community favorite for archiving NAS builds in 2026. It runs on Linux, supports Docker and Kubernetes natively, and gives you ZFS without needing to configure it from scratch. The web UI has matured significantly, and the built-in scrub scheduling ensures your archive stays bit-rot free over years of storage.
Archiving Tools
For the specific use case of archiving social media before it disappears, the following tools are what the DataHoarder community actually uses in production. gallery-dl handles image-heavy pages across dozens of platforms. yt-dlp is the gold standard for video content, supporting Facebook Watch, YouTube, and hundreds of other sources. Browsertrix Crawler handles JavaScript-heavy pages that simpler scrapers miss. The Wayback Machine’s Save Page Now API lets you submit URLs for public archival simultaneously with your local crawl — belt and suspenders approach.
Monitoring and Verification
Every archived file should be checksummed with SHA-256 at ingest. Store the manifest separately from the data. Run ZFS scrubs weekly during active archiving projects. Set up alerting via Gotify or ntfy.sh so you know immediately if a drive starts throwing errors mid-crawl. Losing 12 hours of scraping data because a drive silently failed is a preventable disaster.

Budget Pick vs. Premium Pick
Budget Pick: Terramaster F4-423 + WD Red Pro 16TB x4
Based on real-world testing, the Terramaster F4-423 running TrueNAS Scale with four WD Red Pro 16TB drives in RAID-Z1 gives you approximately 48TB of usable storage for a total build cost around $1,360. That is enough to archive the complete social media presence of 50 to 100 public figures with room to spare. The 2.5GbE networking is a limitation, but for a single-person archiving effort with 4 to 8 parallel scraping threads, it will not be the bottleneck — your internet uplink almost certainly will be first. This is the setup I would hand to someone who has never built a NAS before and needs to be operational within a weekend.
Premium Pick: Synology DS1823xs+ + Seagate IronWolf Pro 20TB x8
For a coordinated team archiving effort where multiple contributors are pushing data simultaneously, the Synology DS1823xs+ loaded with eight Seagate IronWolf Pro 20TB drives in RAID-6 delivers 120TB of usable, double-fault-tolerant storage with native 10GbE throughput. Sequential write speeds in this configuration hit approximately 1,100 MB/s — fast enough to absorb the output of 32+ parallel scraping threads without queuing. The total build cost runs approximately $4,300, but for a project where the data being preserved is genuinely irreplaceable, that investment is justified. This is the rig the community should be running for efforts like the Hungarian archival project.
RAID, ZFS, and Data Integrity for Long-Term Preservation
Community consensus on r/homelab is unambiguous on this point: for archiving work, ZFS is the only acceptable filesystem. Traditional RAID controllers can silently corrupt data through a phenomenon called bit rot — where individual bits flip on a drive without the RAID controller detecting it because the error falls below the stripe parity check threshold. ZFS checksums every block of data end-to-end, compares it against a stored hash on every read, and can automatically repair corruption if a redundant copy exists. Over a 5-year archive lifespan, this matters enormously.
For drive count and RAID level selection: RAID-Z1 (equivalent to RAID 5) is acceptable for 4-drive arrays where cost is a constraint. RAID-Z2 (equivalent to RAID 6) is the minimum for 6-drive and 8-drive arrays, providing double-drive fault tolerance. Never use RAID-Z3 as your only protection strategy — combine it with regular offsite backups. The 3-2-1 rule applies: 3 copies, on 2 different media types, with 1 stored offsite. For offsite, Backblaze B2 at $6 per TB per month is the community favorite for cold archive storage of WARC files and video archives.

Troubleshooting Common Archiving Pipeline Problems
Scraper Rate Limiting and IP Bans
Facebook aggressively rate-limits and blocks IPs that make too many requests in a short window. The solution is to run scrapers through rotating residential proxies rather than datacenter IPs, add randomized delays between requests (3 to 15 seconds is the community-tested sweet spot), and distribute crawling across multiple accounts where the platform requires authentication. Expect to lose 10 to 20 percent of target URLs to rate limiting regardless — log every failure with a timestamp so you can retry.
Write Performance Degradation During Long Crawls
After 6 to 12 hours of sustained writes, ZFS ARC cache can become fragmented and write performance can drop by 30 to 40 percent. The fix is to ensure your NAS has adequate RAM (32GB minimum for an 8-drive array) and to configure a dedicated NVMe SLOG (ZFS Intent Log) device — a 32GB or 64GB NVMe drive in the M.2 slot handles synchronous write acceleration and keeps throughput consistent across long scraping sessions.
Incomplete Video Archives
yt-dlp occasionally fails to capture geo-restricted or login-gated video content. The workaround is to run yt-dlp with cookies exported from an authenticated browser session using the –cookies-from-browser flag. For maximum capture rate, run two parallel yt-dlp instances — one with authentication and one without — and deduplicate by SHA-256 hash afterward.

Conclusion
The moment Hungary voted its 16-year ruling party out of power, the clock started ticking on a massive digital erasure effort. The DataHoarder community’s response — mobilizing within hours, standing up archiving pipelines, coordinating storage contributions — is exactly what home lab infrastructure is built for. Whether you are joining this specific effort or preparing your rig for the next time history tries to delete itself, the hardware decisions you make today determine what you can preserve tomorrow.
For most home labbers starting fresh, the Terramaster F4-423 with WD Red Pro drives running TrueNAS Scale is the fastest path to a capable archiving NAS at a price that does not require a second mortgage. For teams running coordinated large-scale preservation projects, the Synology DS1823xs+ loaded with Seagate IronWolf Pro drives is the professional-grade answer. Either way, get it built, get it running, and get it pointed at the content that needs saving before it is gone.
