J Drive

Revision as of 11:18, 13 March 2012 by Roveson (Talk | contribs)



Each CAEDM account and group has a separate network filespace to save files and access them later. Every J Drive user and group space is backed up nightly and is limited in size.

User Filespace

This is your personal filespace on the J:Drive. All CAEDM users have some amount (set by your Quota) of disk space on the J:Drive. This disk space can be managed from the "Disk Space" tab of the CAEDM Account Manager. Note that your user filespace and your group filespace are different, and the quotas on both do not affect eachother.

Besides the normal storage directories (Picturs, Videos, Documents), there are a couple of special directories in your J:Drive filespace. The 'groups' and 'www' directory both have special function. Your 'www' directory is the root directory of your webspace. It is empty by default, but if you create a file called 'index.html', it can be viewed from a browser at the URL 'http://www.et.byu.edu/~username'. The 'groups' directory, on the other hand, is a directory of links to the group filespaces you have access to (whatever groups you might be a member of). Do not delete the 'groups' directory.

Group Filespace

These filespaces are accessible from your J:Drive at the path '~/groups/groupname'. You have access to the filespace of any group you are a member of. You can also see the status of all your filespaces from the CAEDM Account Manager. The group filespace always has at least a 'www' directory, wherein you can modify the group webspace. The group webspace is viewable in a browser at the URL 'groupname.groups.et.byu.net'.

There may also be a directory called 'scratch' in your group filespace. This is a link to the scratch space, which is temporary storage for all of CAEDM. Note that this space is not backed up, and if you leave your files here, nobody is responsible for them.

Quota

J Drive usage and disk quota limits for users and groups can be viewed using the CAEDM Account Manager.

Accessing the J Drive from On Campus

The J Drive is available by default from:

Windows Machines

Many BYU campus computers will be able to 'map' your J:Drive as a network drive. By mapping your J:Drive, your computer will treat and see your CAEDM J:Drive as it would any of its other local disk drives such as it's C:Drive or a USB thumbdrive. To do so, follow these instructions:

My Computer Method

  • Right click "My Computer" and select "Map Network Drive...".
  • Select j: as the drive in the "Drive" box.
  • Type in the "Folder" box \\fs-caedm.et.byu.edu\CAEDMusername.
  • Select "Connect using a different user name".
  • Enter your CAEDM user name and password.
  • Click "OK" and then "Finished".

Command Prompt Method

  • Use the 'net use' command with server 'fs-caedm.et.byu.edu'.


To unmap the J:Drive, do the following:

  • Right click "My Computer".
  • Select "Disconnect Network Drive...".
  • Select from the list of network drives "J:".
  • Click "OK".


If you are using a laptop computer, keep in mind that BYU Guest wireless and other on-campus networks may not currently support mapping your J:Drive. The easiest thing to do is connect physically by ethernet to BYU's network or to BYU Secure wireless if you wish to map your J:drive to your computer.

Macintosh Machines

You can also access your J:Drive from a Mac OS X machine on campus by doing the following:

  • Select the Finder
  • From the top menu, select go > connect to server.
  • In the window type the following: cifs://fs-caedm.et.byu.edu/YOURCAEDMNAME
  • Click 'Connect'
  • A screen will pop up prompting you for your username and password. Make sure your name is the same that you use to log into caedm.
  • Done! You can access your J: drive files straight from your mac's finder.

Linux Machines

You can use scp with the sever 'scp.et.byu.edu', or you can map the drive with SAMBA (fscaedm.et.byu.edu).

Accessing the J Drive from Off Campus

Windows Machines

There are a few ways to access your J:Drive files from off-campus:

SFTP of SCP: These are two protocols for transferring or copying files from one computer to another. There are client applications such as Filezilla or WinSCP that allow you to work on your files in place or drag-and-drop from one computer to another. To use either one of these or one of the many other programs available, you may need to download and install them first.

For whichever program or application you choose to use: 

Hostname: sftp.et.byu.edu
Port: 22
User: your CAEDM username
Password: your CAEDM password

Connecting to your J:Drive using WinSCP (NOTE: If you have FileZilla or another FTP client, these same settings will apply.):

  • Go to the website and download the free client.
    • To install the software, download the "Installation Package."
    • To use the client on a computer without permission to install software, download the "Standalone Application."
  • Start WinSCP. Enter the following information in the corresponding fields:
Hostname: sftp.et.byu.edu
User name: <Your CAEDM User Name>
Password: <Your CAEDM Password>
  • Click 'login'. (NOTE: You will recieve a message about trusting the server. Click 'yes' (if you trust us).)
  • WinSCP will then show a window with two sides, the left is your home computer, and the right shows files on your J: drive. You can drag files between your computer and your J: drive.

IMPORTANT NOTE: This method will probably not work from public hotspots like libraries or coffee shops, as the required port (22) is usually blocked.

Other Methods

CAEDM VPN: You can set up a connection to the VPN to access your files.

Off-campus RGS workstations: Your J:Drive is mapped to them automatically.

Citrix applications: These have access to your J:Drive. You can save files to and open files from your J:Drive using these applications.

Email them to yourself: This works too. But keep in mind that some email providers may have caps on the size of the mail that can be sent and some files are too large to be sent.

Macintosh Machines

To access your J:Drive files from off campus on Mac OS X, do the following:

  • Set up the VPN.
  • Use the steps above for accessing your files from on campus.

Linux Machines

You can use scp with the sever 'scp.et.byu.edu' or use the VPN.


NOTE: Keep in mind that depending on your operating system, some of the above methods may require different efforts or may not be supported entirely

Backups

All user data not stored in the 'scratch' directory is backed up nightly. To restore lost data from the tape backup, use the CAEDM WebRestore tool accessible in the 'Restor Files' tab of the CAEDM Account Manager.
