I understand that you are new to the forum however in order for anyone to provide you good answers and to possibly solve your problem you need to read the forum rules, provide details of your system if it's relevant, and provide good details of the problem. Based on the way you are typing I would guess that English is not your primary language. Try to use a simple language translator from your native language to English. If English is your language then you need to slow down and create comprehensive sentences. We truly do want to help but we need clarity.I can know who you delete?
Yes, of course it's possible to overwrite files.Sorry for the lack of details, and thanks for the help.
Is it possible to overwrite files?
You do not. Once the space has been marked as unused then it is available for data to be written. FreeNAS does not overwrite the data with the intention of wiping the data, that is something different.Thanks, how do you stop overwriting? I did not create any script
Depending on your pool's redundancy type/setup you may be able to recover some files using PhotoRecWin or similar software.recover freenass file
Is there a place where I see all the snapshots saved?You do not. Once the space has been marked as unused then it is available for data to be written. FreeNAS does not overwrite the data with the intention of wiping the data, that is something different.
If the data in question is very important then I'd shut down FreeNAS and contact a data recover service. They MIGHT be able to recover the data.
Is there a place where I see all the snapshots saved?Thats an interesting thought, will PhotoRec work on ZFS? Everything I've read would suggest that 'normal' recovery tools won't work on ZFS
RunIs there a place where I see all the snapshots saved?
zfs list -t snapshot
or dive into a hidden subdirectory named .zfs
.I know little about it, too. If a file is striped then maybe a half of it can be recovered. If it is mirrored then maybe the whole of it. If some other redundancy applies - then I don't know.will PhotoRec work on ZFS? Everything I've read would suggest that 'normal' recovery tools won't work on ZFS
Yes, they'll list in the web GUI. Where will depend on which version of FreeNAS you're using, which you should have told us in your first post, but didn't, so the best I can tell you is to RTFM for your version to find out where they're listed.Is there a place where I see all the snapshots saved?
