<b>The size of your backup means nothing. The thing you can't reproduce is the only thing worth saving.</b>
Everybody backs up the 50GB of media that's already on your CDN and could be re-fetched in an afternoon, then skips the 200MB that actually can't be rebuilt: user accounts, orders, lead data, link mappings, conversion history.
Tier your backups by reproducibility, not by byte count. Save the irreplaceable hourly; let the regenerable assets ride a slower lane.
Hauling around terabytes of recoverable junk while your irreplaceable data sits on one disk is backup theater.
Back up what you can't rebuild, first and often. Fight me in the comments.
