How to back up the literature database in EndNote to the cloud?

EndNote facilitates cloud backup of literature databases primarily through its synchronization feature with EndNote Online. This ensures your core library data remains accessible across devices. Essential principles involve synchronizing library content to EndNote's secure cloud servers. Necessary conditions include possessing an EndNote Online account, active synchronization activated within EndNote desktop, and reliable internet connectivity. This primarily applies to the main library file (e.g., Library.enlx) containing references, groups, and metadata. Crucially, be aware that the compressed back-up file (.enlx) created locally is distinct from the synchronized library and file attachments stored in the .Data folder require separate backup procedures to a chosen cloud storage platform. Implementing cloud backup involves first signing into your EndNote Online account within the desktop application and enabling synchronization in the preferences menu. This automatically pushes the library structure and reference metadata to the cloud. To comprehensively safeguard all data, including attachments, regularly create a compressed library backup (.enlx file) via File > Compressed Library (.enlx) and manually transfer this file, along with the entire .Data folder, to a preferred cloud service like Dropbox, Google Drive, OneDrive, or iCloud. This approach provides essential data security and facilitates disaster recovery, cross-device access, and collaborative research continuity.
