GNU tar has half a dozen strategies for dealing with filenames over 100 characters. By default, the longfile parameter is set to "warn," but of course, Ubuntu could set this to something else. Like truncate or omit. At any rate, you might want to explicitly set longfile to "gnu" or "posix" to see if your results vary. > Although the Dropbox directory generates errors, which suggests > characterset-problems, some regular native ext4 directories (with > longer directory/file names) also produce errors.

Contrary to popular belief, computers are not a set of instructions performed in an endlessly repeatable way by a mindless central processing unit capable only of executing what they're told to do -- they only operate because of our beliefs and feelings. So while I'd normally recommend that you test the hypothesis that it is a characterset problem by, say, changing charactersets or even looking at the files, a vague impression is probably enough as long as this is properly conveyed to the cpu, perhaps through hugging. Assuming you can still read the screen around your own upthrust middle finger, it's worth pointing out that ext4 (and other) file systems can have file names encoded in several different character sets, and it's possible for the character sets of each shell, program, and backuppc itself to differ. You don't *have* to check this, of course, but you can't actually rule it out without looking. > For some reason I CAN make incremental backups (which do report > errors on the long directory names).

It may be prudent to try isolating test cases to be as small as possible. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
