A method for remote mirroring of digital data, said method comprising the steps of: copying the data from a primary network server to a nonvolatile data buffer in a data transfer unit which is digitally connected to the primary network server, the primary network server including an operating system which is capable of accessing a nonvolatile server store, the data copied to the data transfer unit being a substantially concurrent copy of data which is being stored by the operating system in the nonvolatile server store of the primary network server; copying the data from the data transfer unit to an input end of a communication link which has an output end physically separated from its input end; generating and sending a spoof packet to the operating system of the primary network server; and copying the data from the output end of the communication link to a nonvolatile server store on a remote network server. view more

The method of claim 25, wherein said step of generating and sending a spoof packet precedes said step of copying the data from the output end of the communication link.

The method of claim 23, wherein said step of generating and sending a spoof packet occurs in response to a triggering event selected by a user from the group consisting of: receipt of the data by the data transfer unit which is digitally connected to the primary network server; storage of the data in a nonvolatile buffer in the data transfer unit which is digitally connected to the primary network server; copying of the data from the data transfer unit to the input end of the communication link; copying of the data from the output end of the communication link to a second data transfer unit which is digitally connected to the remote network server; and copying of the data to the remote network server. view more

The method of claim 25, wherein data which is being stored by the operating system in the nonvolatile server store of the primary network server travels along an internal communication path having a predetermined internal bandwidth, and said step of copying the data from the data transfer unit to the input end of the communication link comprises: buffering at least some of the data within the data transfer unit; and copying the data to a communication link which has a lower bandwidth than the internal bandwidth of the primary network server. view more

The method of claim 25, further comprising the steps of: compressing the data prior to said step of copying the data from the data transfer unit to the input end of the communication link; and decompressing the data after said step of copying the data from the output end of the communication link. view more
