Abstract:
1. A computer readable medium encoded with a computer program for use in connection with a processor for managing disk capacity allocated to a data log in a source data storage system during a merge process wherein data in the data log may be merged into corresponding data on a destination storage system connected to the source data storage system by at least one communication link, comprising: logic instructions, stored in the computer readable medium which, when executed by the processor, configure the processor to maintain a ratio of merge writes out of the data log to writes from a host computer into the data log within a desired range until a write process reaches a predetermined distance from the end of the data log; and logic instructions, stored in the computer readable medium which, when executed by the processor, configure the processor to quiesce writes from a host computer into the data log until the data log is fully written to the destination storage system.
