cmd_backup does not store node information for leading directories

[middelink]

Output of restic version

restic compiled manually
compiled with go1.8 on linux/amd64

Expected behavior

Include at least the information for directory given on the cmdline. Don't start in it. (follow rsyncs lead, rsync -avHAX rsync://xxxx / restores everything correctly for the entire tree, including /)
Change the snapshot title to "Directory/File" or something.

Actual behavior

Only the file seems to be backed up. However the snapshot "Directory" indicates that it comes with the full path.

I have some issues with it.

• (minor) it is unexpected. The heading says "Directory" but it is "File" in this case. I would prob have expected /home/middelin/go/src/github.com/middelink/restic/src/cmds/restic or cmd_rebuild_tree.go or something. Although I realize that opens up another can of worms.

• In case of actually using a directory, say /, the snapshots tree points to the contents of /, but does not contain /. This means if I want to restore the backup, I will not get the permissions, ownership etc of / restored. (which is important to me personally as I make full system image backups and let restic figure out the dedupping.)

I agree, this is not good style. I'm currently reworking the archiver (in #842), and I'll change the code to do what tar does: have the complete path that is given on the command line. I'm going to close this as a duplicate of #549 (which is even more severe).

Hm, I re-read your report, and I think you have a (different) and very valid point about the permissions of the top-level directory. Reopened.
