You don't have to lough here. ;-) There is a subtle difference between scp and rsync which many admins don't know well: As soon as you start to copy a file to a remote destination via scp where the target file name exists the following happens: a) Target file is removed. b) Copy is started with the sink being the destination file name GROWING while copying. The same in rsync: a) Temporary file on target is created in the target directory. b) Copy is done to that temporary file. File grows while copying. c) IMPORTANT: Until now preexisting target file is untouched! d) When copy is ready, temporary file is renamed to target file. Conclusion: The time frame where you have a inconsistent file is much lesser with rsync. And while rsyncing one web server to the other you will have a time frame with inconstitencies which you want to be as small as possible.
