Method and System for Enabling Simultaneous Copy of a File Among Two or More Hosts

A method and system is disclosed for enabling simultaneous copy of a file among two or more hosts.

Consider three hosts such as Host A, Host B and Host C. Among these hosts, a file is being copied from Host A to Host B. At the same time, Host C may also initiate a copy operation of the file from Host B. Fig. 1 illustrates a scenario where such copy operation may raise problems with a copy of the file on Host C.

As shown in fig. 1, there may be instances when copy operation on Host C would get completed first as the available file on Host B may not be a complete copy of the file on Host A. This results in a partial copy of the file on Host C.

In order to avoid this scenario, connection between Host B and Host C is kept alive until Host B has the complete file transferred from Host A in accordance with the method and system disclosed herein.

This is achieved by introducing a check in a file transfer server to check if a file that is being transferred has been created in an "Append Mode" (for downloading/copying the file from some other location) rather than "Read/Write Mode". If, yes, then Host B keeps the connection with Host C alive while simultaneously transferring whatever packets of the file it receives from Host A until the complete file is transferred.

Therefore, in accordance with the method and system disclo...
