Are open files handled during backups?
The Backup Manager provides the option to backup any files that are then open. However the results of an open file read are not guaranteed (the backup may be completed while you are working in a file and those changes may not be captured by the backup manager). In order to guarantee 100% backup results and to prevent skipped open files during backups you need to start the backup manually after you finish work or the system will save the changes in the next backup schedule that you set.
