Please do not post the same question in multiple threads, it will likely get you banned. I read them all and I can tell you may have lost your data and I can see that you want it back very badly. Give it a day and do some more searching using your favorite search engine for "truenas recover snapshot" and similar words. I'm not a snapshot guru so I unfortunately cannot help but your question will have a lot of eyes on it so be patient.

Please post the exact version of TrueNAS you are running, and you system specs. I know you posted it in one of the many threads that I deleted unfortunately and I'm sorry for that. Just stick with this one thread and you will get an answer, hopefully within less than 24 hours from now.

I hope you are able to recover your data and wish you the best of luck.

If a complete dataset is destroyed so are all snapshots associated with it.

Does it mean sir there's 0 chances of recovering it? that it wont recover anymore or even i used tools for recovery it doesn't make sense anymore sir?

If a complete dataset is destroyed so are all snapshots associated with it.

What were the steps you took to "delete" the snapshots and datasets? Everything is vague right now.
