Systems and methods for performing data replication

A system for performing data replication, the system comprising:

• at least one computer application executing on a computing device and configured to generate operations associated with data on a source storage device associated with a source storage system;
• a filter module disposed between the at least one computer application and the source storage device, the filter module configured to:
• monitor a plurality of journal entries associated with writing data to the source storage device;
• identify a first journal entry of the plurality of journal entries, the first journal entry comprising a first data modification operation, a first file identifier descriptor (FID) of a file to be modified by the first data modification operation, and a first location of a first portion of the file to be modified,
• wherein a FID identifies a file or directory of a file system on the source storage system and is usable to construct an absolute file name for transmitting data to a replication system;
• identify a second journal entry of the plurality of journal entries, the second journal entry comprising a second data modification operation, a second FID of a file to be modified by the second data modification operation, and a second location of a second portion of the file to be modified,
• wherein the first journal entry and the second journal entry are from the same journal;
• a processing module configured to:
• determine that the first and second data modification operations can be combined into a single modification operation based on a determination that the first and second FIDs both correspond to a first value;
• and
• combine the first and second data modification operations based on said determination;
• and
• at least one database thread configured to construct an absolute file name for replaying the single modification operation on replication data of a destination storage device by associating the first value with a short name and at least one directory name, wherein neither the first nor second journal entries comprises the absolute file name,
• wherein the destination storage device stores a replicated version of data written to the source storage device.

• and
• means for transmitting the single write operation and the absolute file name to a destination storage device to replay on the destination storage device the data modifications associated with the first and second write operations,
• wherein the destination storage device stores a replicated version of data written to the source storage device.
