Influx Data missing after restore

I have been trying to backup and restore data from one remote host to another. It has been giving me issues. It restored the the tables perfectly, but for the individual data points inside the table - some data points are missing after restore. I went back to check old host and the points are there, but not in the restored data in new host. Does anyone know what could be causing this problems? I have been using Influx documentation below for backup and restore.
