Another option for backing up your library and working between different computers is to use EndNote Online. Your EndNote Online library will mirror your desktop version EndNote library when synchronized. For more details see the EndNote Online LibGuide.
Never store an EndNote working library on any cloud service such as Dropbox for sharing, or even for your own use on multiple computers. This will lead to library corruption because of the way cloud services synchronise files over the internet.
Also, never store a working library on a flash drive. These methods are inadvisable because when you are working in EndNote, it is saving data to multiple files, and the data must be saved in a set sequence. When cloud services transfer that data, they may change the sequence of file saves. This eventually leads to library corruption. The library may appear to be fine for days, weeks, or even months, but will eventually be corrupted.
