Quota Allocations

There is a maximum quota allocation alloted to you for each of the areas listed below.

Area Maximum Quota
AFS (Andrew File System) 2 GB *
MyFiles 2 GB
Google Apps @ CMU 30 GB
Exchange Email 10 GB
Cyrus Email 10 GB

* Those who are working on specific projects may request additional space through a Project Volume.

Exceeding Your Quota

If you've exceeded your maximum quota, you must remove files.

Note: On a cluster Linux computer, dragging items into the trash and emptying it will not free up space in your quota. To remove files, you must open a terminal window and use the rm command to free up space.

Tips for Managing Your Quotas

Email Quota

  • Store archives of old email messages to disk rather than on-line.
  • Store archives of project related email messages to disk rather than on-line.
  • Routinely clean out your Sent Mail and Spam folders, deleting messages you no longer need.

AFS Quota

  • Remove unwanted files from AFS
  • If the files are associated with a specific project, you may qualify for Project Volume space; for more information see the Project Volumes.
  • Archive or compress old project files.
  • Within Unix, use the gzip utility to zip files:
    At a command prompt enter: gzip file_or_foldername. To unzip a gzipped file, enter: gunzip file_or_foldername.gz
  • Using the compress and uncompress utilities:
    At a command prompt enter: compress file_or_foldername. To decompress a file or folder enter: uncompress file_or_foldername.Z

    Note: For additional help with using these commands, please refer to the man pages within Unix.
