1. A method, comprising:
- detecting, by a processing device, a hard link creation operation with respect to a file;
creating, by the processing device, a change log record to reflect the hard link creation operation, the change log record comprising a first identifier of a first index node and a second identifier of a second index node, wherein the first index node references a first physical location of contents of the file before the hard link creation operation and the second index node references a second physical location of the contents of the file after the hard link creation operation;
appending the change log record to a change log file;
creating a file name alias comprising the identifier of the second index node; and
performing a file system operation by accessing the file using the file name alias.

Abstract
Systems and methods for identifying files in change logs using file content location identifiers. An example method may comprise: detecting a file system operation associated with a file; and creating a change log record comprising an identifier of a first data structure referencing a first physical location of contents of the file before the file system operation, and an identifier of a second data structure referencing a second physical location of the contents of the file after the file system operation.

8. A system, comprising:
-
a memory; and a processing device, operatively coupled to the memory, to; detect a hard link creation operation with respect to a file; create a change log record to reflect the hard link creation operation, the change log record comprising a first identifier of a first index node and a second identifier of a second index node, wherein the first index node references a first physical location of contents of the file before the hard link creation operation and the second index node references a second physical location of the contents of the file after the hard link creation operation; append the change log record to a change log file; create a file name alias comprising the identifier of the second index node; and perform a file system operation by accessing the file using the file name alias. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a processing device, cause the processing device to:
-
detect, by the processing device, a hard link creation operation with respect to a file; create, by the processing device, a change log record to reflect the hard link creation operation, the change log record comprising a first identifier of a first index node and a second identifier of a second index node, wherein the first index node references a first physical location of contents of the file before the hard link creation operation and the second index node references a second physical location of the contents of the file after the hard link creation operation; append the change log record to a change log file; create a file name alias comprising the identifier of the second index node; and perform a file system operation by accessing the file using the file name alias. - View Dependent Claims (16, 17, 18, 19, 20)
