# Cloud Storage Pro

## Overview

Cloud storage is three different tools wearing one trench coat: sync (access everywhere), backup (disaster recovery), and sharing (collaboration).

Confusing them causes real damage: sync mirroring ransomware, 'backup' that deletes with you, sharing links that leak.

Pro usage: right tool per job, deliberate folder structure, tight sharing hygiene, and costs under control.

## When to use

- Choosing between cloud storage providers
- Storage full / costs growing unexpectedly
- Designing shared team storage that stays organized
- Understanding sync vs. backup vs. archive
- Cleaning up years of accumulated cloud files

## Core concepts

- **Sync != backup.**
  Sync mirrors everything including deletions, corruption, and ransomware. It's convenience + availability, not protection. Pair with real versioned backup.
- **Provider landscape.**
  General (Drive, Dropbox, OneDrive, iCloud), S3-style object storage (cheap, technical), and specialized (photo, code). Match to the job.
- **Selective sync.**
  Not everything needs to be on every device. Sync active work; keep archives cloud-only. Saves disk, bandwidth, and battery.
- **Sharing hygiene.**
  Link sharing: expiry dates, view-vs-edit, password where sensitive. Audit shared links quarterly — stale links are exposures.
- **Storage tiers.**
  Hot (frequent access), cool (monthly), archive (yearly/never). Move aging data down tiers; costs drop 5-10x per tier.
- **Versioning.**
  Enable file versioning where offered. It's the undo button for ransomware, overwrites, and 'oops' deletions.
- **Cost control.**
  Audit what's using space (usually: photos, videos, old project assets). Tier or archive the cold 80%. Set billing alerts.
- **Egress awareness.**
  Downloads out of some clouds cost money (notably S3-style). Know your provider's egress pricing before mass downloads/migrations.

## Practical workflow

1. **Clarify the jobs.**
   List what you need: sync (which devices?), backup (of what?), sharing (with whom?), archive (how cold?). Assign each to the right tool.
2. **Choose providers deliberately.**
   One primary sync provider + backup solution + archive tier. Fewer providers = less fragmentation and cost.
3. **Structure the storage.**
   Top-level: Active, Shared, Archive. Consistent naming. Don't replicate your entire local disk 1:1 — curate.
4. **Configure selective sync.**
   Active projects local; archives cloud-only. Revisit when projects complete.
5. **Lock down sharing.**
   Default links: view-only, expiring. Audit existing shares; revoke stale ones. Sensitive = specific people, not 'anyone with link.'
6. **Enable versioning.**
   Turn on where available; verify retention periods. Test restoring an old version once.
7. **Tier cold data.**
   Identify untouched-for-a-year data; move to cool/archive tiers. Automate lifecycle rules where supported.
8. **Set cost guardrails.**
   Billing alerts, quarterly storage audits, lifecycle policies. Review: does each GB earn its rent?

## Common pitfalls

- **Sync as backup.**
  The classic catastrophe: ransomware encrypts, sync faithfully uploads, 'backup' is also encrypted. Separate versioned backup, always.
- **Unlimited sharing links.**
  'Anyone with the link' forever, for sensitive files. Expiry + specific people for anything non-public.
- **Hot-tier hoarding.**
  Terabytes of untouched files on expensive hot storage. Tiering is the easiest money in cloud storage.
- **No selective sync.**
  500GB synced to a 256GB laptop. Sync is a cache of active work, not a mirror of everything.
- **Egress surprises.**
  Migrating terabytes out of S3-style storage without checking egress fees. Calculate before moving.
- **Fragmented providers.**
  Files across six services, none complete. Consolidate to the minimum that covers the jobs.
- **Ignoring versioning limits.**
  Assuming versions last forever. Check retention; extend for critical data.
- **No exit plan.**
  Years of data with no export tested. Verify you can actually get your data out — before you need to.
