Does anyone know if there’s something that’s the equivalent of USN on exFAT drives? I have some data on an exFAT drive that I would like to include in a backup but don’t want to have to do a scan of all the files every time the drive is backed up.
Ah. Too bad. Thanks. I have read about the TexFAT journaling extensions but can’t find out where this is implemented except in IOT devices.
If you find a way, please post. All I could find quickly was articles (including Microsoft’s) saying no way.
I don’t know if this is what you mean, but exFAT has a TexFAT in WinCE as a transactional file system.
Comparison of file systems says it has Metadata-only journaling where the Rationale fits transactions.
Transaction-Safe FAT File System mentions TexFAT.
Note that in the Comparison above, the exFAT line mentioning TexFAT has a flat No to File Change Log.
A file change log differs from a file system’s journal.
so when searching for a solution, please look for something useful to the application, not internal to FS.
