So encryption will be with ssh. Thanks.
Then, considering both options, my question would be what happens if the
internet connection failed for some period of time? Will the second command
keep visitors waiting?
Are there any different kind of solutions? Where only changed data is synced?
Is such a solution likely to be slower than using dumps?
