This relates to a few known bugs in smbclient processing the name of the server; you may get some mileage out of shortening the name to 8 characters or fewer and only using uppercase letters.

Unless they're running the same version of Samba with the same bug, I wouldn't expect them to have the same problem. > Nothing useful has appeared in my searches and the specific function > name does not seem to appear anywhere in the BackupPC list archives.

Well, since it's an smbclient issue, you'll want to start there. Source code is available, and it may be sufficient to compile the latest version from source rather than using a buggy packaged version (I'm looking at you, Ubuntu.) Of course, with the source, you can debug it using the standard toolchain as you see fit. However, let me echo what Holger said, in that it's probably better to move to a more robust transport with native semantics like rsync. If it's local anyway, tar should also work fine. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
