Is $200 to repair a leaking copper pipe near water heater a fair price?

My water heater was installed in 2015. During these 10 years, I’ve had multiple leaks around the pipes connected to the water heater, including tiny pinholes on the pipe wall, small holes on the other side, and fitting area leaks. The leaks always happen around the upper copper piping near the heater. The current leak appears to be spraying directly from a small perforation on the copper pipe itself. Since I am not on-site, I need to understand what the typical repair method should be and want to ensure the repair is done properly, not just a temporary patch.
