Another Possibilities for Data Backup

Users may also make use of Data Storage (Datová úložiště) provided by the association CESNET (Terms of Service, valid from July 9, 2018), which is a very simple procedure based on the following three steps.

1. Set up a user account at MetaCentrum
2. Check your directories at CESNET Data Storage
3. Back up your files to CESNET Data Storage

Step 1: Set up a user account at MetaCentrum

• Fill in a registration form available at https://metavo.metacentrum.cz/en/application/index.html. Your identity will be checked on-line through the Czech Academic Identity Federation eduID.cz. (Choose options “eduID.cz” and “Institute of Physics” and enter a username and a password for your VERSO account). You will receive an e-mail about a new account creation in a few hours.

Step 2: Check your directories at CESNET Data Storage

• Log in to a Data Storage login server. Use a username and a password for your MetaCentrum account.

ssh username@ssh.du4.cesnet.cz 

• Check the directories VO_metacentrum-tape_tape/ and VO_metacentrum-tape_tape-archive/

ls -l VO_metacentrum-tape_tape/
ls -l VO_metacentrum-tape_tape-archive/

• Alternatively create a subdirectory for your data backup or your data archive

mkdir VO_metacentrum-tape_tape/directory-for-backup/
mkdir VO_metacentrum-tape_tape-archive/directory-for-archive/

Step 3: Copy your files using the rsync or scp command

• Log in to the server you are going to copy files from

• Change to the directory you are going to back up

cd ~/backed-up-directory/

• Run the rsync or scp command

rsync -avz backed-up-directory username@ssh.du4.cesnet.cz:VO_metacentrum-tape_tape/directory-for-backup/
rsync -avz backed-up-directory username@ssh.du4.cesnet.cz:VO_metacentrum-tape_tape-archive/directory-for-archive/
