First of all you must know that by definition the FTP protocol doesn't allow multiple tasks (requests) on the same connection.
Due to the fact SiteVault must handle multiple requests on the same FTP connection we built a very powerful FTP client that is capable of managing a virtually unlimited number of requests.
You will be pleased to see that while a Backup or Restore task is in progress you will still be able to access your FTP connection (that is involved in the Backup/Restore process).
Basically you can do an unlimited number of tasks on the same FTP connection. SiteVault request-management system will take care of the rest.
Even more: browsing data will have priority. That means that when you open (select) a folder the task of reading that folder will be moved on the top of the queue.
Tree browsing mode especially created for FTP.
You will also enjoy an interface that do not locks, due to the fact that all tasks are processed on different threads. Copy/Paste from one FTP connection to another is also supported.
The new PHP gateway will allow you to copy files a lot faster than using regular FTP. This means the backups will run faster and it will use less resources.
