I'm storing ~13 TB. Just enough that online backup (Backblaze etc.) is too expensive to be reasonable, not enough that tape is really sensible. ZFS fits the bill, and let me build a reliable off-site backup system to HDDs. LTO-7 has 6TB of capacity per tape, so I suppose I could get away with... well, ten or so? But it'd be a lot more manual work, and the tape drives are far more expensive than four 8TB HDDs. With tape, there's also the issue that if you only have one tape drive, you don't know if your tapes are readable in anything else.
