I'm looking at building a file system sync utility that monitors file system activity, but it appears that some of the file system monitoring features in the linux kernel are obsolete or not fully featured.
What my research as found
dnotify came first with notification has the features of notifying for delete,modify,access,attribs,create,move can determine file descriptor, however is now out dated by inotify and fanotify
inotify came out second with notification has the features of notifying access, modify, attrib, close, move, delete, create, etc however it does not give you a file descriptor or process and will be outdated by fanotify
fanotify is the latest which informs of access, modify, close, but does not inform of delete or attribs, but does provide file descriptor
I need a way of determining the process (e.g. from fd) and things like delete, modify, attribs, etc in order to sync everything, any suggestions? Unfortunately dnotify seems the best but most out-dated
