Zotero Syncing - version history and restoring tags and attached files
I work with zotero on a large, collaborative project (about 8 people per library) where we store thousands of journal articles to be reviewed and work across 4 different taxa specific zotero libraries. A colleague opened an old computer yesterday (Oct 3, 2017) that she hadn't used since June 2017 and synced Zotero. She chose the "remote" version for all syncing but zotero updated the remote version with her local instance, thus deleting 6 months of organization, tagging, and file attachments to each of the references. Why did this happen given that she chose the "remote" version for all syncing? How can this be prevented? What is the best way to restore both the tags and information, as well as all of the pdf file attachments?
