I did notice Windows' internal command MKLINK appears to be able to visa versa - if you want create hard link to target, you need custom implementation of CreateHardLink and not use FILE_OPEN_REPARSE_POINT (if you will use NtOpenFile) or FILE_FLAG_OPEN_REPARSE_POINT if you use CreatFileW ) So you can simply use CreateHardLink as is and nothing more need todo. the lpExistingFileName opened with option FILE_OPEN_REPARSE_POINT Also, (and I could be wrong about this) the functions provided in the GitHub repo seem to only be compatible with Windows 10 and later, but I'd hope to at least support Windows 7 as well.ĬreateHardLink create hard link to the symbolic link (reparse point) themselves, not to the target. I also came across some code snippets from a Google developer ( ), with some details on the implementation of CreateHardLink and whatnot, but it seemed a little too low level for me to make any real sense out of it. Is there possibly a solution using only the Win32 API? So theoretically, I guess I could just use the system function in C, but to be honest, it feels lazy and I tend to avoid it. Now I'm stuck wondering, what's the solution to this? How can I create a hardlink that points to a symbolic link itself as opposed to the target? I did notice Windows' internal command MKLINK appears to be able to create hardlinks to symlinks. Symbolic link behavior-If the path points to a symbolic link, theįunction creates a hard link to the target. Unfortunately, the page for CreateHardLink clearly states: Thus, if symbolic links exists in a prior backup, I must be able to point to the symbolic links themselves, not the target. Quick background to this question as I'm sure it'll raise a few eyebrows: I'm developing a command line tool in C for making backups, and I am implementing incremental backups using NTFS hard links. You can run this command at any time and make a safe copy of the repository, regardless of whether other processes are using the repository. This subcommand makes a “hot” backup of your repository, including all hooks, configuration files, and, of course, database files. You don't need to stop the server's services when you run svnadmin hotcopy: I've shut down the svn service, so there's no danger of someone Please, double-check that you are using up-to-date Subversion command-line tools (what svnadmin -version says?). Tried 2 different QNAP nas boxes) I get various errors, always aįrom what I see, an unexpected network error indeed occurs when you hotcopy the repository onto your NAS. Work, but if I try to write the files directly to a shared folder (I Doing that to a local folder of the same PC seems to I want to set up an automatic incremental backup of my SVN See KB106: Getting Started with Backup and Restore and KB137: Choosing backup destination. It supports backup scheduling, encryption, incremental backups and backups to remote shares and Azure Files cloud. Note that you can consider the built-in Backup and Restore feature.
