> IncrementalTableBackupClient.incrementalCopyBulkloadHFiles uses HFile.isHFileFormat() to filter files before copying. This method opens each file and reads the trailer to verify magic bytes, which requires a remote I/O round-trip per file. For backup output directories with many files, this is unnecessarily slow.
