I've been down "LTO at home?" rabbit-hole... I nearly ended up buying a SAS HBA, until I realized that S3 Glacier is tape-as-a-service.
S3 is too expensive to do a restore from. And you have to restore to verify.
AWS is an option up to 30TiB, but also feeds into the over-provisioned data-center market pressures. The recent "rclone --gui" solution does bestow rsync/sshfs like features for Windows users now, and remote mounts are easier/cleaner to bring up. =3
Just bought an LTO drive yesterday (after failing to cool its predecessor properly - dont be like me). They got more expensive more or less in line with HDDs :(
