SyncBackPro allows the user to backup or synchronize their files with an email server whether SMTP, POP3, or IMAP4 (not to be confused with synchronizing emails). This is similar to backing up via FTP, however the backup is made via an email server e.g. Gmail, Yahoo!, etc. SyncBackPro provides advanced customization of the settings that allow the user to define SMTP and POP3/IMAP4 server connection details like "Must use SSL/TLS connection", "Direct SSL/TLS connection", and includes the ability to create a custom email body instead of using the default.
You can backup and synchronize your files via cloud storage services. Google Cloud Storage is a service for storing and accessing your data on Google's infrastructure. The service combines the performance and scalability of Google's cloud with advanced security and sharing capabilities.
