Ok, so that's the issue - your version of perl on arm only uses 32 bit IVs. I'm surprised it is built that way - does anyone know if that is default for perl on arm generally?
That means the file size (and mtime) are limited to 2^32. Fortunately rsync-bpc doesn't suffer from this, so your backups of large files are fine. However, viewing their metadata in the CGI interface, or using BackupPC_tarCreate, BackupPC_ls or BackupPC_attribPrint will not show the right file size. Let me think about how to do a workaround in the perl BackupPC::XS module.
