I’m at a crossroads and after some advice to decide if I stay on Truenas and persevere or go back to DSM on Synology If you can help in any are I will be very grateful :slight_smile: I was using synology DSM suited my needs. The cost of their hardware in Australia is getting too high for what I ne…

By online nas you meant a “local nas that is always online”. yes then create a new learn-dataset and learn snapshots with that. Then use your backup nas as a target for snapshot replication. If online nas means a VPS on the internet (not in your local lan) - do the opposite. Create your learn-datas…

First of all, relax. I fully understand your excited + worried situation here. Linux has come a long way since last 20 years, and does not bite that often now a days , especially the selected ones coming from windows background :grinning: Yes, Macrium Reflect is a perfect choice for this. I am us…

Thanks :slight_smile: I shall relax and continue to take my time. I’m a bit worried not having a running backup regime yet still ok because my offline backup has all non-replaceable media to date. I even have a 3rd NAS which was my backup until it was dropped by a removalist. Catastrophic failure …

Yes, your snapshot will serve the purpose of a read-only copy. I know its a bit difficult to get the head around this concept initially. Let me try to explain it in a simpler way as I perceive it. Think of the first snapshot as a Full backup and all the following snapshots as diff backups. Now if t…

Here’s the simplest and clearest explanation I’ve seen of snapshots: [image] Snapshots defy math and logic. "THEY DON'T MAKE SENSE!" Resources Why ZFS “snapshots” don’t make sense A children’s book for dummies, by a dummy nerd_face +1 “I don’t really underst…

That is a good summary thank you. I thought of a snapshot as a map of the data that prevents deleted blocks being overwritten which allows them to be recovered until I delete the snapshot. Is that assessment correct? In my scenario of media I can take a snapshot and each time I add media take a new…

Quick question. For the learning process are you advising a dataset on my backup NAS or one on my online NAS? I’m unsure if using the online NAS with another dataset can still let me learn the same skills but it would be more convenient to begin learning each element of the required steps for my ne…

[image] mgrobins: Is that correct? Pretty much. Typically you’d take snapshots on a schedule, for a specified lifetime.
