File Servers
DTU Compute IT Support maintains file servers which provide a number of filesystems. Some of the more “important” ones are mentioned below.
List of file systems:
Important
*nix refers to Unix-like operating systems, here mostly Linux but also macOS. The *nix paths are mounted and accessible from Linux servers, and rarely used directly on client machines. Mounting network shares on macOS is done using the Windows path (CIFS protocol), and Linux clients can do this as well.
$HOME
Description: Standard Unix-like home-directory. Mounted as x:\ on Windows. Every user has exactly one folder.
| *nix path | /home/<username> |
| Windows path | \\nas1.compute.dtu.dk\home|home1|home2|home3|home4\<username> |
| Backup frequency | Daily |
| Live data | Yes |
| Snapshots | Yes |
WINHOME
Description: A CIFS-only share mounted as h:\ on Windows. Every user has exactly one folder.
| Windows path | \\nas1.compute.dtu.dk\winhome\<username> |
| Backup frequency | Daily |
| Live data | Yes |
| Snapshots | Yes |
Project
Description: Areas with greater capacity than $HOME but lower backup frequency. Ask DTU Compute IT Support for a folder.
| *nix path | /project/<projectname> |
| Windows path | \\comp-nas3.compute.dtu.dk\project\<projectname> |
| Backup frequency | Weekly |
| Live data | Yes |
| Snapshots | Yes |
Note
All files are synced daily to a shadow server which ensures that only up to one working day of data is lost in case of a complete failure of comp-nas3.compute.dtu.dk
DTU-Compute
Description: Areas that are available from both DTU Compute servers as well as from DTU Computing Center cluster machines. Ask DTU Compute IT Support for a folder.
| *nix path | /dtu-compute/<projectname> |
| Windows path | \\comp-nas3.compute.dtu.dk\dtu-compute\<projectname> |
| Backup frequency | None |
| Live data | Yes |
| Snapshots | Yes |
Note
All files are synced daily to a shadow server which ensures that only up to one working day of data is lost in case of a complete failure of comp-nas3.compute.dtu.dk
NoBackup
Description: Larger disk areas mainly for performing calculations on the linux clusters. Ask DTU Compute IT Support for a folder.
| *nix path | /nobackup/<projectname> |
| Windows path | \\comp-nas3.compute.dtu.dk\nobackup\<projectname> |
| Backup frequency | None |
| Live data | Yes |
| Snapshots | Yes |
Note
All files are synced daily to a shadow server which ensures that only up to one working day of data is lost in case of a complete failure of comp-nas3.compute.dtu.dk
Groups
Description: Area for group based projects. Mounted as k:\ on Windows.
| *nix path | - |
| Windows path | \\nas1.compute.dtu.dk\groups |
| Backup frequency | Daily |
| Live data | Yes |
| Snapshots | Yes |
WWW Docs
Description: Web pages for courses, projects, etc.
| *nix path | /www/docs |
| Windows path | \\www2.compute.dtu.dk\docs |
| Backup frequency | Daily |
| Live data | Yes |
| Snapshots | No |
WWW Pages
Description: Personal www pages. Every user has exactly one folder.
| *nix path | /www/home/<username> |
| Windows path | \\www2.compute.dtu.dk\<username> |
| Backup frequency | Daily |
| Live data | Yes |
| Snapshots | No |
Windows Backup
Description: A CIFS share for taking backup of a Windows PCs
| Windows path | \\nas1.compute.dtu.dk\backups\<username> |
| Backup frequency | Daily |
| Live data | No - Copy of local data |
| Snapshots | Yes |
Note
Use of this share is deprecated. Backup is made to the server backup.compute.dtu.dk via the comp-backup program
*nix Backup
Description: A file server for taking backup of a Linux/Mac PCs
| *nix path | backup.compute.dtu.dk:/home/<username> |
| Backup frequency | Daily |
| Live data | No - Copy of local data |
| Snapshots | Yes |
