Is it possible to get back a previous version of a document?

during an update of a calc document I removed some important information.

If you did not take any precautions - no.

Did you enable Always create backup copy in Tools | Options | Load/Save |General ?

If so, look in your backup directory which is shown in Tools | Options | LibreOffice | Paths.

If you are on Mac, replace Tools | Options with Preferences | LibreOffice.

There is an option, Menu/File/Version
