I would like to save some money, and since I already pay for Google Drive storage, I was hoping that I could back up my zotero to it. Is that possible?
You should not place your Zotero database directly in Google Drive, but it is possible to use Google Drive to sync attachment files in your My Library. This is done most easily using the Zotfile plugin. See here for details: https://zotero.org/support/sync#alternative_syncing_solutions
