Hi MSK,
thanks for sharing your experiences!
I’ll monitor this thread as I also want to backup from one ZimaBoard2 unit to another ZimaBoard2 unit. So having your experienced issues fixed and getting to a reliable status is absolutely crucial!
I’m also still new to the ZimaOS world, and while I like the tinkering aspects of it, a rock solid backup and data / system safety is an absolute must-have. Basically a NAS’ very genuine main purpose. But I’m seeing in this forum here sometimes some posts, which are worrying to me.
Speaking of that, I stumbled over these 2 posts here, which you maybe also want to take a deeper look. Basically you need to establish and backup the system disk as well, since the RAID1 configuration information is stored there. If the system disk dies or gets corrupted with a faulty OS update for example or whatever accident happens, then big headaches would start, if there is no backup of the system, in particular of that specific config data.
I’m wondering what other steps / precautionary measure should be also considered. Perhaps a very senior experienced ZimaOS person can comment on. I bought ZimaBoard units and into ZimaOS to primarily have a safe place for my data and proper backups. Having to read a couple of user experiences with lost access to RAID setups, not fully functioning backups, no out-of-the-box system backup and restore approach offered user-friendly in ZimaOS, is not really acceptable and makes ZimaOS looking not ready for prime time.
