After takeoff; the gear would not retract. I then selected SYS 2 and gear retracted normally. However; SYS 2 was deferred. We continued flight to destination and submitted AML for system 1.In hindsight; I've considered my action to use system 2 was wrong because of the deferral. During preflight and review of the Aircraft Release /AML; it was apparent that this was an ongoing maintenance issue. A recent flight had the same problem on takeoff and elected to use other system also; So in my mind; there was uncertainty on what was the problem between system 1 and 2. Additionally; there was not any history of landing gear extension issues; so at the time and in heat of the moment; I believed I was taking the safest course of action. Weather (snow and ice) was a consideration. I didn't want to leave the gear hanging if ice was present.
Airbus Captain reported using System 2; even though it was deferred; to retract the landing gear when it failed to retract using System 1.
