Re: [rdiff-backup-users] [Errno 39] Directory not empty

[Joe Steele]

I can't say what exactly caused your problem, but I can reproduce 
such an error this way:

 | $ mkdir -p src/d1/d2
 | $ mkdir backup
 | $ touch src/d1/f1
 | $ touch src/d1/d2/f2
 | $ rdiff-backup src/ backup/
 | $ touch backup/d1/d2/f3
 | $ rm -rf src/d1/d2/
 | $ rdiff-backup src/ backup/
 | Exception '[Errno 39] Directory not empty: 'backup/d1/d2''

In the above example, a new file was manually created in the 
backup directory.  This results in rdiff-backup getting confused. 
 Such changes are, of course, a bad idea.

I can clean up the mess by removing the file and running the 
backup again:

 | $ rm backup/d1/d2/f3
 | $ rdiff-backup src/ backup/
 | Previous backup seems to have failed, regressing destination now.

So -- is there any chance files were created in your backup 
directory by means other than rdiff-backup?  The rdiff-backup 
program depends on the accuracy of its file lists found in 
<backup-dir>/rdiff-backup/mirror_metadata.*, and if they don't 
match the contents of your backup directory, then problems will 
eventually arise.
