A couple of remarks. Nagra recorders are among the best you can get, so sound quality is no problem. But I have worries about saving vinyl on tape, since tape gets worn out faster then vinyl, is vulnerable to dirt, magnetic fields, changes in temperature and dirty or mis-aligned playback-heads. If you want to make a back up from LP's for daily use, I suggest you burn them onto CD's and keep your vinyl in a vault :). Seriously, I don't think putting them onto tape is worthwhile. If you want, you can load your vinyl in a PC, restore the sound a little (noise, cracks etc.) and then burn them on CD. Also a lot of trouble, but IMHO worth it.
