I self-host my own Google Photos alternative, and my cloud backups are so much cheaper than what Google offers

Google did away with its free photo backups quite a long time ago, instead opting to count even compressed backups against your overall Google Drive usage. While Google's pricing isn't bad for storage ($20 annually or $2 a month for 100GB), it's actually possible to get even cheaper elsewhere, all while maintaining control of your data. Combining Immich and Backblaze B2, a terabyte of storage is merely $6 a month, and you pay for what you use, so the costs are even less than that for most people.
