Can you outline some of the pros and cons of different data backup methods for laptops or mobile devices?
Using custom backup scripts or backup software designed for laptops or mobile devices both work well under the right circumstances. The main drawback to these approaches to backup is that there are never any guarantees of how long a user is going to be connected to the corporate network. There is a very good chance that a user may log off before a backup completes.
Continuous data protection products that are designed for laptops can often remedy this problem because they are designed to stream data to the backup target any time the user is logged on. If a user disconnects, then the software simply resumes the upload process the next time that a connection is available. Some organizations have begun using technologies such as Microsoft's DirectAccess to ensure that the user is connected to the corporate network any time that they have Internet access. Doing so allows the backup to run, even if the user isn't accessing any corporate resources.
