I wanted to do my own self-hosted storage but for the cost and features I went with Dropbox. It’s $10 a month if you prepay for the year otherwise it’s $12 and you get two terabytes of storage. For that you get all the same things most self-hosted solutions will offer including 30 days of versioning/backups. Additionally it’s pretty popular so most software has built in integration which is convenient but not something you need. Bottom line is doing your own storage can be cheap but adding off-site backups gets expensive and just going straight to off-site backups (cloud storage) is going to be close to the $10-$12 dollars you’ll pay anyway but you have to do all the work.
