cloud backup

Hello, I'm trying to figure out a good and cheap option ( short term ) to have my nas TS-464 back'd up to cloud. Wondering what option(s) people use? For long term, I've been thinking about local storage using TrueNAS. Thanks

Any recommendations of a firm or an expert who can remote in to help us setup a cloud backup for both of our DS-214+ ??? Prefer someone with a lot of Synology-to-cloud backup experience. We just lost our IT manager to serious health issues. Central time zone ... thanks Gents!
