how to backup my mac without time machine

I've been using Time Machine for years, backing up 3 Macs with no less than 512GB storage used (each). Could go 3 or more if you are looking at many TB of data. You don't have to go 2 bay.but it is great to have the ability to have drive redundancy. Pretty aniemic.slow, and won't run the more modern and robust BTRFS file system. I would not recommend their low end J series. File serving, or syncing.one may expect better performance. For backups, slow and steady is fine most of the time, as it chugs away in the background. Same for all brands low-end choices will be the slowest. There is a reason high-end file servers have lots of RAM and large CPUs. throughput can be limited by many things, including RAM and CPU. One thing to consider: The cheapest boxes, are, well, cheap. Makes it easy and secure to get data or backup anywhere you have a network connection, without having to know an IP, fuss with firewall rules, or even touch a router. I really think their Quick Connect is under-rated. Backing up and sharing is enough to justify the cost. The best part is all you can do with it.but don't feel compelled. Not perfect.but nothing in the consumer price range is.

I have used both Drobo and Synology, and strongly recommend the Synology.
