Can you give us a bit more informationj? What is the full rdiff-backup
line that apparently causes the problem? What linux os are you running
on the server?

I'm been stumped by a problem for days.
I use nothing but linux and have been using rdiff-backup for years to backup
all my machines to one central server. I use the traditional method of the
central server reaching out using ssh.
A friend wanted me to setup a backup of their windows machine to a linux server.
I tested this at home by making windows machine with cygwin on it.
It works just like my linux clients where the central backup server reaches out
It works great.
I then setup a linux server and windows machine at the friends house. As far
as I can tell, the setup is (almost) identical to my test system at home.
I setup the linux server at the frien's house the same as my home system. I
have a user called rbackup that performs the backup. I pre-created the
destination/target folder and made rbackup the owner. When rdiff-backup runs
for the first time, it does a complete backup successfully. However, for some
reason,when rdiff-backup is finished, it removes some permissions from the root
of the destination folder.
The permissions change from:
The next time rdiff-backup runs, it fails with many permission errors.
For example, it says permission denied for
The reason for this seems to be because (at some point in this second backup)
rdiff-backup removed even more permissions from the root of the target folder.
They end up as:
Firstly, why is rdiff-backup making modifications to the root of the target
Secondly, why does it do the most asenine thing that it can possibly do by
removing all the permissions?
As a test, on the system with the problem, I tried to run a local backup. That
is, the central server makes an ssh connection to itself to run a backup. This
backup runs fine and does not modify the root of the target folder.
I gather I must have some difference between my test system (at home) which
works, and this troublesome system, but I can't finger it out!
