Class DurableFileWriter

Prevents partial write (e.g. power cut) by writing to a temporary file first. As a final step the following options are supported:

  1. Replacement with taking a backup: It replaces the target file with the temp file using OS Replace API. Replace method also does a backup of the target file first. If the file is corrupted the backup file contains the latest content prior to the crash. https://source.dot.net/#System.Private.CoreLib/FileSystem.Unix.cs

See more details: https://github.com/dotnet/runtime/issues/18034

  1. Replacement with ReplaceAPI but without a backup: Renaming a file in the same volume is atomic operation. In this mode Replace call uses Interop.Sys.Rename(sourceFullPath, destFullPath) internally.
