✅ Key Features

✅ Prevents multiple instances using a lock file (/tmp/run_azcopy.lock).
✅ Reads a file with directory-to-container mappings.
✅ Validates each source directory before syncing.
✅ Checks if the destination container exists (test write).
✅ Stops immediately on any error (clean runs only).
✅ Monitors azcopy every 30 seconds and stops if business hours begin.
✅ Processes all directories sequentially using an array (fixing loop issue).
✅ Uses one log file for the entire run.
