You can set your own parallel file downloads limit. By default BackupSheep servers only make 3 connections when downloading your files. However, you can set this limit between 1 to 10. This can significantly increase backup speed.
Please note that increase in the number of parallel downloads may trigger firewall rules in your FTP/SFTP server and it may block our endpoint IPs BackupSheep IPs. Higher parallel download connections can also lead to high load on your server.
