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.
