I've looked at all the previous similar questions, but the answers seemed to be all over the place and no one was moving a lot of data (100GB != 10TB).
I've got about 10TB that I need to move from one raid to another, gigabit net, XFS file systems. My biggest concern is having the transfer die midway and not being able to resume easily. Speed would be nice, but ensuring transfer is much more important.
Normally I'd just tar & netcat, but the raid I'm moving from has been super flaky as of late and I need to be able to recover and resume if it drops mid process. Should I be looking at rsync?
EDIT: looking into this a bit more, i think rsync might be too slow, i'd like to avoid this taking 30+ days. So now i'm looking for suggestions on how to monitor / resume the transfer with netcat.
