· Schedule an incremental backup to a usb drive · run the schedule to create the first full backup · remove the drive · run the schedule again What should obviously happen is that you get a message saying that the tib file can't be found, an opportunity to connect the drive, and a chance to retry task. When the task runs, it should create an incremental backup, leaving the first full tib file intact. What actually happens on my computer is that I get an ugly I/O error first. Pressing cancel brings up a nicer dialogue box. I plug in the usb drive, press 'retry', and the task deletes the full back up and creates a new one! This basically means that scheduling incremental backups to a usb drive is impossible unless I keep the drive in the computer the entire time; unheard of if you're a laptop user. Can anyone confirm this please? Thanks.
