Narrative:

At cruise; the right engine vibration was at 4.0 and in the amber caution range. The captain handed controls over to me and went through the QRH procedure for high engine vibration. When reducing power 2 percent the vibration went down to acceptable levels. The captain tried contacting dispatch to see if a return to ZZZ was the best course of action; the dispatcher replied follow the QRH and gave no other guidance. At this point we were past the 1/2 mark and continued to ZZZZ. Upon landing it was noticed that the same engine vibration has been written up in the logbook 10 previous times in the last two weeks. In addition it was discovered on the last maintenance write up for the engine vibration; a high powered engine run was required but only an engine run to 45% N1 was completed and the maintenance write up was signed off as good. When calling maintenance in ZZZZ; the maintenance personnel advised the captain against writing the engine up again; as it was contract maintenance in ZZZZ and not much they could do. This posed a huge safety risk to the passengers and crew of future flights.
