完全和不完全恢复都将使用备份映像，可以启用或不启用前滚操作 - Overflowlogpath - specify the location of the logs during a rollforward operation to allow access logs in multiple locations
Overflowlogpath指定前滚操作中的日志位置，以便在多个位置访问日志。 - Reverting is potentially much faster for this purpose than restoring from a backup ; however , you cannot roll forward afterward
采用此方法还原很可能比从备份还原快得多；但是，此后您无法对数据进行前滚操作。
