receiving a user-initiated command to control the replication system; generating a connection object; determining if the connection to the replication system has been initiated; sending the command to the replication system if the connection is initiated; obtaining input from a character stream to process; processing data for use by a backup system; if the connection has not been initiated: generating a reader thread; receiving asynchronous I/Os; checking for a response from the replication system; and reading into a buffered I/O stream. ### Claim 2 (depends on 1) The method of claim 1, wherein generating a connection object enables persisting data that is pertinent to a secure socket connection between a backup system and the replication system. ### Claim 3 (depends on 1) The method of claim 1, wherein generating a connection object comprises generating a connection object to assemble and translate the command to the replication system. ### Claim 4 (depends on 1) The method of claim 1, wherein obtaining input from a character stream to process comprises obtaining input from a character stream comprising alpha-numeric-punctuated characters in an XML document. ### Claim 5 (depends on 1) The method of claim 1, wherein generating a connection object comprises generating a connection object wherein usage of memory pertaining to the connection object includes operating system (OS)-specific read and write handles that redirects I/Os to and from a secure shell and to a backup system. ### Claim 6 (depends on 1) The method of claim 1, further comprising: generating an external binary to establish a secure shell connection to the replication system; redirecting communications between the secure shell connection and a component library of the backup system; asynchronously tracking I/Os to and from the secure shell connection; and re-establishing the secure shell connection if secure shell connection is disconnected. ### Claim 7 An apparatus, comprising: electronic hardware circuitry configured to: generate a secure connection with a replication system using credentials; receive a user-initiated command to control the replication system; generate a connection object; determine if the connection to the replication system has been initiated; send the command to the replication system if the connection is initiated; obtain input from a character stream to process; process data for use by a backup system; generate a reader thread if the connection has not been initiated; receive asynchronous I/Os if the connection has not been initiated; check for a response from the replication system if the connection has not been initiated; and read into a buffered I/O stream if the connection has not been initiated. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the circuitry comprises at least one of a processor, a memory, a programmable logic device or a logic gate. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the circuitry configured to generate a connection object enables persisting data that is pertinent to a secure socket connection between a backup system and the replication system. ### Claim 10 (depends on 7) The apparatus of claim 7, wherein the circuitry configured to generate a connection object comprises circuitry configured to generate a connection object to assemble and translate the command to the replication system. ### Claim 11 (depends on 7) The apparatus of claim 7, wherein the circuitry configured to obtain input from a character stream to process comprises circuitry configured to obtain input from a character stream comprising alpha-numeric-punctuated characters in an XML document. ### Claim 12 (depends on 7) The apparatus of claim 7, wherein the circuitry configured to generate a connection object comprises circuitry configured to generate a connection object wherein usage of memory pertaining to the connection object includes operating system (OS)-specific read and write handles that redirects I/Os to and from a secure shell and to a backup system. ### Claim 13 An article comprising: a non-transitory computer-readable medium that stores computer-executable instructions, the instructions causing a machine to: generate a secure connection with a replication system using credentials; receive a user-initiated command to control the replication system; generate a connection object; determine if the connection to the replication system has been initiated; send the command to the replication system if the connection is initiated; obtain input from a character stream to process; process data for use by a backup system; generate a reader thread if the connection has not been initiated; receive asynchronous I/Os if the connection has not been initiated; check for a response from the replication system if the connection has not been initiated; and read into a buffered I/O stream if the connection has not been initiated. ### Claim 14 (depends on 13) The article of claim 13, wherein the instructions causing the machine to generate a connection object enables persisting data that is pertinent to a secure socket connection between a backup system and the replication system. ### Claim 15 (depends on 13) The article of claim 13, wherein the instructions causing the machine to generate a connection object comprises instructions causing the machine to generate a connection object to assemble and translate the command to the replication system. ### Claim 16 (depends on 13) The article of claim 13, wherein the instructions causing the machine to obtain input from a character stream to process comprises instructions causing the machine to obtain input from a character stream comprising alpha-numeric-punctuated characters in an XML document. ### Claim 17 (depends on 13) The article of claim 13, wherein the instructions causing the machine to generate a connection object comprises instructions causing the machine to generate a connection object wherein usage of memory pertaining to the connection object includes operating system (OS)-specific read and write handles that redirects I/Os to and from a secure shell and to a backup system.
