Transferring Data on Viper

For less than 100GB: you can skip to using universal method or skip to your OS: Windows / Mac / Linux.

Small to medium amounts of data

This can be carried out using a number of SFTP-styled packages such as sftp, scp, rsync, and Filezilla to name a few. Filezilla can be downloaded as a Windows application and may be more suitable for people who prefer a Windows environment, rather than the command line.

Note that plain FTP is disabled on viper.hull.ac.uk and SFTP (secure FTP) is the recommended method.


The following can only be performed on Windows after installing MobaXterm or PuTTY.

The example user is user1; you will need to enter your own username here:

From your local computer to Viper
scp myfile user1@viper.hull.ac.uk:myfile
rsync -av my-directory viper.hull.ac.uk:/data/users/YourID
From Viper to your local Computer
scp user1@viper.hull.ac.uk:bio/YourUCInetID/hpc-file
rsync -av viper.hull.ac.uk:/data/users/YourID/mydatadirectory


The following example uses MobaXterm, for transferring large files it is recommended to use FileZilla. For instructions on how to use FileZilla view the Linux section. follow the instruction in the Getting Connected section for installing MobaXterm.
