Restoring a source file referenced by multiple file names to a restore file

A system, comprising:

• a processor;
• a file system having files;
• at least one process accessing files in the file system;
• a restore operation executed by the processor to perform operations, the operations comprising:
• processing an operation to restore a source file having a first file name to a restore file in the file system, wherein the source file is in a state of being accessed by one of the processes;
• determining whether a second file name references the source file;
• creating a first temporary file name and a second temporary file name that both reference the restore file in response to determining that the second file name references the source file;
• determining whether the source file is being accessed;
• performing an operation to release the source file from being accessed;
• and in response to releasing the source file, performing:
• renaming the first temporary file name to the first file name;
• and
• renaming the second temporary file name to the second file name, wherein after the renaming of the first and second temporary file names, the first and second file names reference the restore file.

An article of manufacture comprising a computer readable storage medium having code executed to cause operations with respect to a file system in a system, wherein processes executing in the system access files in the file system, and wherein the operations comprise:

• processing an operation to restore a source file having a first file name to a restore file, wherein the source file is in a state of being accessed by one of the processes executing in the system;
• determining whether a second file name references the source file;
• creating a first temporary file name and a second temporary file name that both reference the restore file in response to determining that the second file name references the source file;
• determining whether the source file is being accessed;
• performing an operation to release the source file from being accessed;
• and in response to releasing the source file, performing:
• renaming the first temporary file name to the first file name;
• and
• renaming the second temporary file name to the second file name, wherein after the renaming of the first and second temporary file names, the first and second file names reference the restore file.
