CP, Rsync or other?
-
Ubuntu 16.04
In the process of getting rid of my 8 year old ReadyNAS with its NFS share .
I need to copy (a complete duplicate would be nice) the data from the NFS share to local storage. Having limited Linux knowledge, I don't know if using rsync or cp is a better option?
I can script either one but would "rsync -av src dst" or "cp -pRu src dst" be best?
I would also like to have this copy only new files after the original copy is done because I will have both of them going until I my maintenance window on Sat. Then I will be able to change the app currently pointing to the NFS share.

rsync is basically always better.

Thanks. Much appreciated.

rsync is what handles the "some things have already been copied" algorithm.

And it will make it much easier instead of copying all the files again.

IT Rule of Thumb: RSYNC is always the right answer

Scott is right. When in dubt use rsync. Anyway cp is faster then the delta algo of rsync. Therefore the basic rule -if you care- should be: first time you copy go cp then always rsync. Even if cp fails you can restart with rsync.
But basically you do not bother and you go straight w/ rsync.
