File Storage, Backups & Restores

Every user with a CPSC account has a:

  1. Home directory on one of our Unix servers in: /home/{grad, prof, research, staff, visitor}/username
  2. Library directory on CS Domain Windows clients (Desktop, Documents, Pictures, Videos, Download). 

These file systems are backed up daily.  One of these dailies is archived at the beginning of each month and kept as a "monthly".  Undergrad monthlies are kept for 18 months while Faculty (grad, prof, research, staff) monthlies are kept for 2.5 years. 

NOTE: Data stored outside these locations or on local drives is not backed up.  Please read here for more information on backups.

Scratch Space

We have additional disk space available for storage of non-critical data. This is an ideal place to keep files that don't need to be backed up, but must be easily accessible.

This service is available to faculty, graduate students and staff. Undergraduates do not have access to this space.

NOTE: This disk space is NOT backed up.

This disk space is accessible directly from your unix account as/home/scratch/username

You may also setup a symbolic link from your home directory with the following command:

ln -s /home/scratch/username ~/scratch

From Windows, you may access this space by mapping the network drive as \\nse\scratch\username. You may also add it as a permanent addition to your login by choosing the "Reconnect at logon" option in the "Map Network Drive" dialogue.

Archive Space

We have additional disk space available for archiving data. This is an ideal place to keep files that are no longer accessed with any frequency but are important enough that they need to be backed up.

This service is available to faculty, graduate students and staff. Undergraduates do not have access to this space.

This disk space is accessible directly from your unix account as /home/archive/username

You may also setup a symbolic link from your home directory with the following command:

ln -s /home/archive/username ~/archive

From Windows, you may access this space by mapping the network drive as \\nse\archive\username. You may also add it as a permanent addition to your login by choosing the "Reconnect at logon" option in the "Map Network Drive" dialogue.

Quotas

Disk quota is the amount of storage space allocated to a user and only applies to undergraduate accounts. All other accounts including faculty, graduate, and staff have no imposed quotas, but will be notified if their usage is deemed excessive.

Undergraduate Quotas

Every undergraduate account is assigned 1 GB on their home directory. In cases where the quota is insufficient to complete course work, a request can be made from the course's professor or instructor.   Also, after a student's 1st year, there is a .5GB increase for each year a student is in the program.

To view your Unix quota limits and usage, run quota -s  in a terminal, or run the CPSC Guide.

Backups

We perform daily backups on all home directories. Daily backups are kept for a week. Weekly backups are kept for a month. Monthly backups are kept from 18 to 30 months.

Data stored on local machines or on /home/scratch are not backed up.

Since backups are performed daily, if a file or directory does not exist for a minimum of 24 hours, it will most likely not be part of a backup. Files that have existed for longer than 24 hours should be recoverable.

File Recovery

If a file or directory was unintentionally deleted or modified and has existed for more than 24 hours, we may be able to recover and restore the files.

Users can submit a request to the Faculty of Science Help Desk for a file recovery request with the following information:

  • The exact path of the deleted files(s) or directory(s)
  • The date and time of the deletion

File recoveries will take one business day to perform and depends on the size of the files to be recovered.

If you deleted your assignment hours before a submission deadline, it is unlikely we can have it restored in time. Please create a file recovery request and cc the request to your instructor and TA.
