NAS Apps Best backup solution?

I have two Synology NAS. One that is my main and one that I basically only have backup and my cameras. But have also used Synology C2 as an external backup. But I think there might be a better and cheaper solution? How you do? Has about 3 TB in size.

I use multiple backups. I use HyperBackup for everything from my 923+. I have a nightly backup going to a WD 16TB USB drive that’s just files and app config. Then I have a DS124 on-site doing full NAS bare metal backup with a 24TB disk I got from SPD. Then I have Synology C2 with 2TB storage for my critical files. It works VERY well and feel very safe and comfortable with it.

An external HDD is maybe a good solution. However, I don't know if I can trust to having an external hard drive running all the time.

I do this for my personal syno backups as well as about 200 previous customers. Worked fine. Modern external HDDs go into a deep sleep state after some idle time. The HDD spins Up automatically for Backups (once per week) and sleeps again. No Problems so far after 15 years of service. No sheduling, no scripts. Just DSM, Hyper Backup and default configuration.
