User Responsibilities

If you are storing "critical" data in your Cyrus email account, AFS and/or MyFiles, it is essential that you keep your own backups to ensure that such critical data is not lost in the case of some unfortunate event. Computing Services will make a "best effort" to restore lost data, however, data recovery is not guaranteed. 

It is up to you to determine if your your data is critical. If you have files or email messages that you do not want to risk losing, you should consider that information "critical" and create your own backup. There are a variety of options for maintaining your own backups of your data. The following are some suggestions for the various types of data.

Cyrus Email Messages

You can save email messages in local folders on your computer. These local folders can then be backed up to an external device as an added measure to protect against loss. Computing Services does not backup locally stored email.

AFS File Space

To backup your AFS data, use SFTP to copy the files to your computer. You can then backup those files to an external device or another file storage option. For information on how to use the SFTP see:


While using a computer lab computer, you can save your MyFiles data (Desktop and My Documents files) to an external drive. If you have lost critical data that was stored in your Cyrus Email, AFS or MyFiles space, you can restore the data provided it was present the last time the data was backed up (See Backup Schedule).
