Public bug reported:
Backup fails due to error when accessing a temporary file:
Under certain circumstances the `files.snar` file cannot be copied from
the temporary directory. This issue is caused by bad permissions of the
created temporary directory. In the case that NSsbackup is called as
superuser first, the temporary directory cannot be accessed by non-
privileged users afterwards and the backup fails.
Experienced with
OS: Ubuntu 8.10
NSsbackup 0.2.0-RC6 installed both from PPA and from source.
Here is the interesting portion of the log:
