Is it possible to find the previous zotero.sqlite.bak files?

Hiii this is my first post.

I accidentally deleted all the files under the "Unfiled Items". I found that the associated "Addon Item" was also removed which means all my reading progress indicators for my items have disappeared :((((((
Half an hour ago, I found a solution: I disabled "Sync automatically" and found my "zotero.sqlite.bak" to change the version of my library items. It worked!
But then I re-enabled synchronization automatically (I don't know why I did that) and restarted Zotero several times. So both "zotero.sqlite" and "zotero.sqlite.bak" files were updated multiple times so that I I can't find the version from half an hour ago.
May I ask if it would be any possible to find that previous zotero.sqlite.bak file? Thanks!

There should be even older zotero.sqlite.1.bak. Beyond that, only if you have some other backup of the files. (Our restore instructions say to make a copy of all zotero.sqlite files before changing anything.)

Hiii thanks for your reply. I found "zotero.sqlite.1.bak" when I first attempted to repair my files and it worked. But it was then overwritten as I changed its file name to "zotero.sqlite" and redid the auto-synic and I didn’t have a backup of the previous versions. Fortunately, the loss wasn't too significant though I did lose the reading progress indicators I’d accumulated over several years.
But I have another question: the file "zotero.sqlite.1.bak" is no longer being automatically generated in the data directory. How can I make it work again? Thanks!
