Thanks for mentioning FOSS Browser, this looks nice

1 TB active, 2 TB Backup on my own storage and 2 TB Backup remote on internxt (lifetime plan).

Before being overly excited about their lifetime offerings (and discounts on such) getting the backups running reliably was a pain up until their last webdav update, so I would consider them with caution. Also I’m not sure they do another round discounts on their plans… at least their marketing mails said it was the last chance - but hey, that also might be a strategy to make you buy in.
