Zoot can synchronize your databases between any number of computers using a cloud synchronization service like Dropbox, OneDrive or Google Drive.
The benefit of cloud synchronization is that you have access to all of your databases on all of your computers without having to manually transfer files yourself.
Another less obvious benefit is database backup automation. When you use a cloud synchronization service your databases are backed up to the cloud.
Some cloud synchronization services will even maintain multiple versions of your databases in case you want to revert to a previous version or retrieve data from a previous version.
Dropbox is one such service and is recommended for use with Zoot.
