The RAID issue has been debated much on this group.
As a former institutional information systems manager who oversaw RAID
systems, in my opinion Tony is right that RAID is not the best backup
system in this case when offsite websharing and backup systems are
easily available at at reasonable cost.
If a RAID controller fails it is very likely that you lose everything
and the resources, maintenance and knowledgebase/ skillset needed to
"do" RAID reasonably safely are WAY beyond her capabilities.
No need for RAID for her when there are better, cheaper and easier
alternatives available now that once weren't.

do the exact opposite of what you think they do.

She didn't SAY she wanted a live backup. She said: "I just want to
have a [raid] setup to back-up my photo archive.".
And even if she does, just how live does a backup need to be? RAID
complicates the system. That can be difficult to justify in the real
world. Assuming she shoots daily, there's no need for more than a
daily incremental backup, and monthly full offsite backups. RAIDs just
multiply the failure rate of each drive, and the RAID can be
impossible to rebuild when many failures occur. When a drive is
striping, the entire system is vulnerable! NO WAY.
Really, she doesn't need disks at all just for good backup, just a
broadband connection.
