No, most of time, we actually need automatic recovery, because Sheepdog
is targeted for thousand nodes cluster, where manual recovery will cause
very high administration. Manual recovery could be complementary to the
automatic recovery, where people can use it with caution for
maintenance. Note, automatic is very crucial to assure data reliability
that we must try our best to assure copies as many as specified, this
means, when you do manual recovery process, you are risking to lose your
data because in that window you have some copies less than expected.

Thanks,
