When copying to an empty partition, rsync provides no advantage over cp -a. It does.
It can verify the copy, or retake an interrupted transfer.
Given that we're normally copying to a directly attached drive, how often do those problems show up? How is copying any different than any other write in this regard. There are already error detection/correction methods in use. Even when copying over a network, there are mechanisms in TCP & Ethernet to detect & correct errors.
Which fail.

:-) You forgot this one: http://en.wikipedia.org/wiki/Murphy%27s_law In my experience, there seems to be an inverse relationship between how critical one's data is and how long it can hang around uncorrupted and undisturbed. The more important it is, the more frequently you should be backing it up. IOW, frequent and redundant backups -- serving both archival and operational needs -- is for all practical purposes the only defense. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
