Abstract
Methods, apparatus, systems and articles of manufacture to perform backup and recovery of data files using hard links are disclosed. Example methods disclosed herein include determining whether a first operation to be performed on a target file by a thread of a process is a file deletion operation, wherein the target file is referenced by a first hard link. Disclosed example methods also include creating, in response to the first operation being a file deletion operation, a second hard link to the target file, where the creation of the target hard link occurs while the thread of the process performing the deletion is blocked. Disclosed example methods further include returning control to the thread of the process performing the deletion after the second hard link is created to enable the operation to be performed on the target file.
