only 2 of 3 files uploaded to FTP server

Google Drive has the ability to "chunk" your backup archive into small parts in order to work around the PHP time limits involved. The FTP protocol does not have the ability to break down the archive, it is trying to upload a 2 Gb part all at one time. With FTP, the upload has to be completed within on PHP time limit period. It isn't going to work with a 2 Gb file.

You can reduce the part size of the archive by going to Configuration, on the Archiver Engine line, click Configure. You can see the Part size for split archive currently set to 2000. You will need to set it much lower for FTP. Try 10, if that works you can try to increase it farther. That will give you a LOT of parts to your backup archive. You need all of the parts to restore the backup.

thank you guys , i split the archive to 512 and worked fine with me the back up is 9 files now and im fine with that.

You're welcome!
