Help with my backup plan please

[ARoel]

Hi,

I'm formulating some sort of my own backup policy because as I just realized, my file organization for the past decades have been a mess (no backups, some even with triplicate files in one HDD) and I'm lucky I was able to recover my decades old family photos. I lost a lot of photos before just because of hardware failures. Surprisingly, not a single one was lost due to a corrupted files (at least from what I can remember). I want to make sure I avoid all that now. 

As of now, I have these:

1. Working PC equipped with 2 x 4TB HDDs, set to RAID1.

2. Home server - Truenas with NextCloud installed, equipped with 4 x 4TB HDDs, set to RAIDZ2 (I think this is similar to RAID6). Set up in the same house where my working PC is.

3. OneDrive subscription

 

My planned backup "rule" as of now is to:

1. Retain ALL raw files in my working PC, whether they be active or not. I'll archive everything there.

2. Working PC is then synced to a folder in NextCloud (Home server). No file in here will ever be touched or accessed unless my working PC gets stolen, catches fire, or things like that, unless I really have to (something which I will try to avoid at all cost). Files will never be uploaded to NextCloud  directly as well.

3. NextCloud is then synced to OneDrive. Similarly, no file will be accessed unless both my PC and Home Server get lost at the same time. No files will ever be uploaded here.

 

I'm new to this and I'm not sure if this is a good plan to follow. I think this is enough protection from hardware failure. or maybe not?

Remember I just said I never had a corrupted file? Not anymore. I just had it last night (It's in this topic:

. )

 

I'm not sure what caused the file to be corrupted but what happened eventually was: corrupted fie in main PC = corrupted file in home server = corrupted file in OneCloud. So, not a single useable file was left. Luckily it was my first file using this new system I want to follow. A blessing in disguise and a wake up call, telling me that I am not doing enough.

So, with all that, what else should I do? Basically, I just want my kids, their kids, grandkids, and so on to still be able to access these files in the future. Thank you.
