Actually, IMO, an rsync job is safer than raid, it covers more failure modes, but not as fast.
It depends on how you define "safe". In my book, the longer a system runs without two identical copies, the less safe it is. There is no way an rsync copy will ever catch up with a RAID1 mirror.
problem with raid is that nothing verify disk failures on unused data. the raid purpose is uninterrupted running, not data saving.
Absolutely.
What is being said? With raid you can setup a background scrub which scans all the member disks and ensures there are no bad blocks and data is consistent. http://en.m.wikipedia.org/wiki/Data_scrubbing#RAID Notice mdraid has support for data scrubbing.
