During the initial climb out of ZZZ we got the HYD2 LO QTY EICAS message. I ran the QRH that instructed us to monitor the affected hydraulic system. I sent an ACARS text to dispatch advising them of our situation and that we possibly will have to divert. As I was texting back and forth with Dispatch I noticed the #2 hydraulic quantity kept decreasing. At that point I made the decision to divert. Initially I wanted to divert to ZZZ1 but later changed the destination to ZZZ2 as it was closer to our current location. I advised Dispatch; Flight Attendant; ATC; and passengers of the situation. Meanwhile; the First Officer and I reviewed the 'Hydraulic System 2 Failure' QRH; just to be prepared for the event that we completely lose the #2 hydraulic system. We started preparing for arrival into ZZZ2 and I ran the overweight landing QRH. Once we were ready and set-up for the approach into ZZZ2; we transferred the controls and I became the Pilot Flying. The approach and landings were uneventful and within the overweight landing criteria. After; we taxied to the gate I made logbook write-ups for the EICAS message; overweight landing; and lockout/tagout device installation.
ERJ145 Captain reported that a hydraulic system failure resulted in a diversion.
