[rdiff-backup-users] Case sensitivity problem

[padoivi]

Hi,

Seduced by the reverse diff and mirroring capabilities of rdiff-backup, I 
decided to start using it.

Everything is working fine but I get problems with files or directories names 
containing capital letters such as "Documentation" which names get converted 
into things like ";068ocumentation" (the worst case being with file names such 
as "README or INSTALL").

I am backing up from an ext3 filesystem (Linux, Ubuntu Hardy) to an ntfs 
filesystem  (external hard drive, USB 2.0 connection) which are both supposed 
to be case sensitive.

I tried the --override-chars-to-quote option (reading from various forum posts) 
but I get the following error message :


>> rdiff-backup --exclude-special-files --override-chars-to-quote "A-Z;" 
>> /home/bob /BackuP/RDIFF-BACKUPS-BOB/home/bob

Any help would be appreciated.
