Possible problems

After a while, the program speeds up and wants to download all the files without distinction.
This is due to a lack of memory that allows PHP to make comparisons and select modified files.
You can increase the amount of memory allocated in the php.ini file, which is located in the Windows directory or equivalent on Unix, as well as the script execution time :
```
max_execution_time = 3000
memory_limit = 1024M
```
It is also possible that the server will close the connection if it lasts too long. A backup device is recommended.

If you installed Windows Live OneCare, which restricts ftp translations, check the program before using it in production.
