I soft-launched this a few weeks back, but here is my most polished (i.e. not very) @rustlang project to date: metadata-backup, a tool for backing up your file system metadata.
Contributions welcome!
@freemo Depends on what you are backing up. A few seconds in most cases, but if you hit something with hundreds of thousands of little files and directories it can be minutes or more (in my case some deduplicating backups).
In my use case backing those up isn't that useful anyway, so a way to exclude them is probably a more fruitful way to speed up my backups.
