Re: [rdiff-backup-users] Security Violation with --compare for FilenameM

From: Jesse Reynolds
Subject: Re: [rdiff-backup-users] Security Violation with --compare for FilenameMapping.set_init_quote_vals
Date: Sun, 9 Jul 2006 23:34:52 +1000
Well now I've tried formatting my backup volume as HFS+ Case Sensitive, but I still get the same security violation message when I try and run a --compare: 

        rdiff_backup.Security.Violation:
        Warning Security Violation!
        Bad request for function: FilenameMapping.set_init_quote_vals

Any ideas anybody?

Full output below.

Thank you
Jesse

[resending...]

Hello
Now I have rdiff-backup version 1.0.4 installed on two servers and I've successfully created a backup of /etc (local is Mac OS X 10.4.6, remote is Solaris 10 x86). But now when I try and do a -- compare I get a Security Violation exception, for function FilenameMapping.set_init_quote_vals.
I can update the local backup copy from the remote just fine, but -- compare fails.
I guess this is specific to backing up to a HFS+ filesystem that is case insensitive. How can I get around this? 

Thanks
Jesse
