Set two years before the movie, it shows John Connors rise from foot soldier to leader. It has a slight cinematic feel thanks to a lot of cut scenes but doesn't impress.
off, online data backup is just as the name implies. Data is backed up over a networked connection (most likely using the TCP/IP standard protocol of the internet) to a remote location (ideally). An offline data backup most often refers to data that is backed up on-site, rather than to a remote location as mentioned above.
I usually do offline backup. I haven't tried online backup. Perhaps, someday I will need online backup but I will choose what kinds of data I will backup online.
