Every File Backup & Sync Method Explained (21 Minutes)

Backup, sync, archive and version history are four different things, and mixing them up is how footage gets lost. This video explains every backup and sync method you'll meet as a creator, one term at a time: the 3-2-1 rule, full / incremental / differential backups, snapshots, RAID 0/1/5/6/10 (and why RAID is not a backup), NAS, SMB and NFS, external drives, cloud sync vs cloud backup, object storage, egress costs, offline and cold storage, tape and LTO, Time Machine and File History, checksums, bit rot, ransomware, immutable backups, encryption, restore testing, and a simple workflow for solo video creators. Tap a timestamp to jump to the term you need.

NOTES
- Numbers on screen that aren't from a named source are examples (file-size and upload-time math, RAID usable-space examples, the project space split).
- I quote no prices. Cloud and hardware prices change; check what a full restore costs, not just storage.
- LTO capacities come from secondary trade coverage and sources differ on the first LTO-10 drives; check the LTO consortium for current specs.
- "3-2-1-1-0" is a vendor naming convention, not a formal standard. The credit to Peter Krogh for popularizing 3-2-1 comes from secondary sources.
- Facts were checked in October 2026. Product behavior and retention windows change, so confirm current details before relying on them.
- This is general education, not advice for your exact setup. "My advice" labels mark opinions.
- Narration is an AI-generated version of my own voice.
