Cloud services like Google Drive, Dropbox, and OneDrive cap free storage at 15GB, insufficient for 4K videos and high-res photos. Paid plans cost ~$100/year, backups crawl on poor Wi-Fi, and privacy-conscious users avoid remote servers. Local backups using USB drives, SSDs, or external HDDs offer fast, unlimited storage without subscriptions or internet dependency.
Google Storage Reality Check
| Service | Free Tier | Photos vs Drive |
|---|---|---|
| Google Photos | 15GB shared | Compressed “Storage saver” doesn’t count (pre-2021) |
| Google Drive | 15GB shared | Full-resolution files count against limit |
| OneDrive | 5GB | All files count |
| Dropbox | 2GB | All files count |
Required Hardware for Local Backups
- USB-C Flash Drives: 64GB-2TB, $10-50, portable
- Portable SSDs: 500GB-4TB, $60-200, fast reads
- External HDDs: 2-8TB, $50-150, highest capacity
- OTG Adapter: USB-C to USB-A ($5), connects drives
Manual Backup Process (5 Steps)
- Connect drive via OTG adapter (appears in file manager)
- Open Files app → Browse → Internal storage
- Select folders: DCIM (photos), Movies, Downloads, Documents
- Tap Move/Copy → Select external drive → Confirm
- Safely eject drive before disconnecting
Automatic Backup Apps
FolderSync enables scheduled backups:
- Free version: Manual sync
- Pro ($4.99): Auto-sync on connection, Wi-Fi only
- Folder pairs: DCIM → External/Photos → External
- Incremental backups save time on subsequent runs
Storage Capacity Comparison
| Content Type | Phone Storage Used | External Drive Needed |
|---|---|---|
| 1000 photos (12MP) | 4GB | 64GB USB |
| 100 4K videos (10min) | 200GB | 500GB SSD |
| Full photo library | 50-200GB | 1TB HDD |
| Everything (photos+videos) | 300GB+ | 2TB+ HDD |
