Hi there,
I have a big problem: I made a survey with multiple versions, each new version usually developed from the previous. Mean while, the data accumulate. At some point, because a lot of version were there and it was confusing for me to find the proper version, I decided to delete some old version of this survey. But by mistake, I deleted the one with the data from last full month and I realize that just few minutes later.
My question is if I can recover the lost data somehow.

I need to say I have some files saved on 23-rd of November, related to this survey ( .lsa, .xml, .lss, .zip) but I don't know how to use them.

Thank you in advance for your advice.

Not unless you have a backup of the database

I added a sentence in my original message where I said I have some files saved, related on this survey. Is one of them good to make a backup?...

"*.lsa" should be fine. Just import them.

The "a" of "lsa" means "archive". This contains the survey structure and the responses.

Wow, I did it! I was very lucky to made this backup file, it was only an exercise, to see how this function work. Thank you very much for your support!

Best regards,
Cristian

A tool that can be interesting : gitlab.com/SondagesPro/coreAndTools/backupSurveyLocally ;)

Thank you, Denis! I forgot to mention that at that point and I did not used the forum since than.
