I’ve been using Synology NASes since 214. Currently running DS218 as my main NAS, DS216 as a mirrored backup for the DS218. DS216 only wake up at 2am to do what it is configured to do, then go back to sleep at 6am.

RAID is not backup - it doesn't guard against file corruption, human errors, catastrophic failure, software bugs, virus/malware, etc,..

I learn it the hard way, my system run on 4 HDD, but the motherboard failed
Now, all gone. How do I prevent such incident again, mirror plus backup?

Mirror or not doesnt matter, what matters most is backup

Did an impromptu backup when the system was giving warning that the mirroring hdd fail and thr 3rd and 4th HDD cannot be detected. Now they did a 1 to 1 exchange, understand everytuing is gone

you can always buy another Synology 4-Bay NAS and slot in the same sequence without data loss.

so must buy at diff places???

my last issue is not hdd but from Synology os.
it just cant read the hdd and got alert say hdd fail. After repair (format), the hdd is actually fine.

Is normal for same batch to die at the same time.

RAID rebuild depends on the RAID type - most people would configure only for 1-disk redundancy (failure) to maximize the usable storage, so if you have more than the disk failure tolerance allowed, you are out of luck.

If you cannot afford data loss; please consider having another backup.

the best approach is as above. However how many of you practice that? Unlikely ba.

at the end of the day you can always ride on luck like some of them here. However i don't take my chances.
