Every adult operator who’s been in business ten years has a backup story. The one where a RAID controller died and took six months of uploads with it. The one where a ransomware script encrypted everything. The one where an overnight migration script silently truncated a table. The ones who tell these stories with a smile are the ones who had real backups; the others aren’t around anymore.
This post is the 2026 backup and disaster recovery playbook for adult tubes: the 3-2-1 rule, hot vs cold content tiers, database vs filesystem strategy, recovery time and point objectives, and how to actually test.
The 3-2-1 Rule
Industry baseline for reliable backups:
- 3 copies of your data.
- 2 different media / storage types.
- 1 copy offsite.
Example meeting 3-2-1: primary server + daily snapshot on same provider + weekly sync to different cloud provider. Three copies, two types of storage, one offsite.
What You’re Protecting
| Asset | Volume | Recovery Urgency | Backup Strategy |
|---|---|---|---|
| Database | GBs to low TBs | High (RPO: ≤ 1 hour) | Logical + physical, frequent |
| Application code | MBs | Low (in git) | Git repository |
| User uploads (new) | Variable | High | Continuous sync |
| Processed videos (HLS, thumbs) | Large TBs | Medium (regeneratable) | Source retained, processed cached |
| Source original videos | Large TBs | Critical (not regenerable) | Cold archive, redundant |
| Configuration files | MBs | Medium | Versioned backup |
| Logs | GBs/month | Low | Rotated + archived |
Tier 1: Database Backup Strategy
Logical Backups (mysqldump / pg_dump)
- Hourly dump of critical tables (tblVideos, tblCMSUsers, tblTokenTransactions).
- Nightly full dump.
- Compressed (gzip) and encrypted before offsite transfer.
- Retention: last 7 daily, last 4 weekly, last 12 monthly, last 3 yearly.
Physical Backups (binlog / WAL)
- Enable binary logging for point-in-time recovery.
- Ship binlogs to offsite storage continuously.
- Combined with full nightly dump: can restore to any minute in the past 7 days.
Replica Servers
- A read-replica doubles as a hot standby.
- Daily snapshot of the replica is cheap and doesn’t stress primary.
Tier 2: Application + Config Backup
- All code in a private git repository (GitHub Enterprise, GitLab self-hosted, or Bitbucket).
- Config files (config.inc.php, nginx.conf, php.ini, systemd units) in a private git repo or encrypted object store.
- Secrets managed via vault (HashiCorp Vault, Bitwarden, or cloud-specific).
Tier 3: Content (Videos, Images)
This is the big tonnage and the most expensive backup problem. Strategy:
Hot Tier: Your Active CDN
The content users stream from. BunnyCDN, Wasabi, etc. Assumed to be always-on.
Warm Tier: Cross-Region Replication
Same provider, different region. Wasabi auto-replicates for low cost; BunnyCDN multi-region storage zones.
Cold Tier: Cheap Archive
- Backblaze B2 — $6/TB/month, ideal for cold archive.
- AWS S3 Glacier Deep Archive — cheapest but slow retrieval.
- Physical disks in a safety deposit box or second location for very large catalogs.
What to Back Up From Content
- Critical: Original source uploads. These are irreplaceable.
- Important: Processed web.mp4 / HLS master.
- Regenerable: Thumbnails, preview clips, contact sheets — can be recreated from source.
Back up what you can’t regenerate; accept the time/compute cost of regenerating the rest.
RPO and RTO: Define Them Explicitly
- RPO (Recovery Point Objective): how much data can you afford to lose? For DB: 5–60 minutes typical. For content: usually the moment of last sync.
- RTO (Recovery Time Objective): how fast must you be back online? 1–4 hours for most mid-size tubes.
Write these down. Design backups to meet them. Test against them.
Restore Testing: Non-Negotiable
A backup you haven’t restored is not a backup. Quarterly:
- Spin up a blank server.
- Restore most recent DB backup.
- Restore config and code.
- Run sanity checks: login works, admin loads, a sample video plays.
- Time the entire process; compare to RTO.
- Document issues found.
Encryption
- All offsite backups encrypted at rest (AES-256).
- Key management: keys never on the same server as encrypted data.
- Rotate encryption keys annually.
- Compliance note: adult user data is often special-category under GDPR — unencrypted backups containing it are a reportable breach risk.
Ransomware-Resistant Backups
- Air-gapped offsite copies (or object-lock / write-once-read-many).
- Wasabi and B2 both offer object lock — backups that can’t be deleted by the holder (or attacker) for a defined period.
- Immutable retention policy on critical archives.
Disaster Recovery Scenarios
Scenario 1: Server Hardware Failure
VPS crashes, RAID dies. Restore from cloud-provider snapshot (RTO: 30 min–2 hr). If snapshot unavailable, full restore from offsite (RTO: 2–8 hr).
Scenario 2: Data Corruption
Bad migration, ransomware, human error. Point-in-time restore from binlog + previous dump (RTO: 1–3 hr).
Scenario 3: Provider Suspension
VPS or CDN provider pulls your account. Full restore to alternate provider from offsite backups (RTO: 4–12 hr).
Scenario 4: Total Facility Loss
Rare but possible (fire, flood, nation-state action). Offsite geographic diversity means you can rebuild elsewhere from cold archive (RTO: 24–72 hr).
Cost Benchmarks for a Mid-Size Tube
| Backup Layer | Typical Monthly Cost |
|---|---|
| Database backups (encrypted, offsite) | $5–$30 |
| Code + config versioning | $0–$20 |
| Content cold archive (10TB) | $60–$100 |
| Content cold archive (100TB) | $500–$1,000 |
| Cross-region content replication | +20–40% of active CDN cost |
Closing Thought
Backup strategy is boring. It’s also the difference between a bad day and a dead business. Build the 3-2-1 structure, match backups to RPO/RTO, test quarterly, and you’ll sleep better than almost every operator in the industry.
