Re: [rdiff-backup-users] Backup Ext3 -> Fat32: files randomly renamed...

Hello Jean-Luc,

no - this is a feature!
Fat(32) is not case sensitive and cannot distinguish between "Document.doc" 
and "document.doc" - so rdiff-backup converts all files to some special 
format which preserves the filename.

see manpage of rdiff-backup 1.1.7 :

--override-chars-to-quote

      If the filesystem to which we are backing up is not  case-sensitive, 
automatic  'quoting'  of  characters
      occurs.  For  example,  a file 'Developer.doc' will be converted into 
';068eveloper.doc'. To override this
      behavior, you need to specify this option.

regards
roland
