    Abstract: Provided are a method, system, and article of manufacture for managing the copying of writes from primary storages to secondary storages across different networks. Information is maintained on a first group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied and a second group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied. A failure notification is received from one of the primary devices in the first or second group of a failure to copy a write from the primary device to the secondary device. A freeze command is issued over a first network, using a first network protocol, to the at least one primary device in the first group to stop copying writes to the corresponding at least one secondary device. A freeze command is issued over a second network, using a second network protocol, to the at least one primary device in the second group to stop copying writes to the corresponding at least one secondary device.

    Abstract translation: 提供了用于管理跨越不同网络的从主存储器到辅助存储器的写入复制的方法，系统和产品。 信息被保持在至少一个主存储器的第一组，至少一个主设备管理对至少一个主存储器的输入/输出（I / O）访问，以及至少一个对应的辅助存储器， 至少一个主存储器被复制，并且第二组至少一个主存储器，至少一个主设备管理对至少一个主存储器的输入/输出（I / O）访问，以及至少一个对应的辅助存储器， 到至少一个主存储器被复制。 从第一组或第二组中的一个主设备接收到故障通知，以将写入从主设备复制到辅助设备。 使用第一网络协议通过第一网络向第一组中的至少一个主设备发出冻结命令以停止将写入复制到对应的至少一个次设备。 使用第二网络协议通过第二网络向第二组中的至少一个主设备发出冻结命令以停止将写入复制到对应的至少一个次设备。

    Abstract: An apparatus, system, and method are disclosed for continuously protecting data. A mirror module mirrors a primary record set to a base record set. A log module accumulates each record change to the primary record set in a log. A change selection module selects a record change from the log. A change application module applies the selected record change to the base record set to form a recovered record set.
