Email Disk Management Tips

July 28, 2011 by Lyle Wiedeman

disk quota

Many faculty and staff, especially those filling multiple roles, find their increasing use of email and email attachments makes it difficult to do University business and remain within their disk quota limits.

While the ideas below won’t apply to all people or all situations, being aware of these strategies should prove useful to many.

Empty your trash

Depending on the program you use to access your email, deleting messages may not actually get rid of them – they may accumulate in your Trash folder and take up space you could use more productively.  If you have messages in your Trash folder, your email program will offer an option to empty it.  Example: in Thunderbird, select “Empty Trash” from the File menu.

Check your drafts and sent-mail folders

There are many circumstances in which partially-written messages are saved to a “drafts” folder.  You should check that folder periodically and delete messages that you no longer need.

Email programs save copies of every message you send.  While many of these messages constitute an important record, it may prove worthwhile to discard messages beyond a certain age or with little long-term value.

Watch your spam

UCI gets a large volume of unwelcome commercial and malicious email and central UCI systems test and repel millions of messages a day.  As a complement to this filter, each account has settings for spam (see My Email Options) which defines a threshold for considering a particular message to be spam, and may quarantine it for inspection and discard.  If you have a spam folder, examine it and empty it regularly.

Ask for more space

If you have already checked that you haven’t lost space to spam and deleted mail, your University role may simply require more space than the default quota provides.  Contact the OIT Help Desk (oit@uci.edu, x42222) to review your particular disk usage and quota options.

Partition your usage

If you have multiple University roles, consider directing email for each role to a separate account.  Quotas are applied to accounts, not people, and this may provide all the additional space you need, or at least protect one account with modest use from the email associated with another.  Group UCInetIDs are available for a small monthly fee which can be used (for example) as mailboxes for deans, directors, and chairs.

Use local storage

Most email programs offer the option of creating “local” folders – i.e., the ability to store email messages on the machine you are sitting at.  The advantage of this is vastly increased storage, but it has the downside that email stored in local folders can not be accessed from other computers.

The most common phenomenon that creates large mail storage is email attachments.  Messages, even those with HTML and a few images, take up little space.  Large documents, high-resolution images, sound files and videos consume your mail storage when they’re associated with your email as attachments.  Consider storing your attachment as a local file and deleting the email that carried it.  If you want access to these documents from multiple computers, consider storing them on OIT’s Webfiles service.

OIT is ready to assist you in assessing your usage patterns and needs, and matching them to available options.

UCI Receives Broadcom Donation

July 28, 2011 by Allen Schiano

disk array

For several years, the Broadcom corporation has been supporting computing at UC with  substantial donations of computing hardware.  Previous donations of computers and disk arrays have benefited other UCs, as well as OIT, ICS, and researchers at UCI.

Broadcom recently donated disk arrays totaling almost 100 terabytes, comprising 24 shelves of high-performance disks compatible with OIT’s existing campus disk storage, used for campus email and departmental shared space.  This donation will allow OIT to expand our available space and improve disk performance.

OIT is currently exploring making network-accessible disk space available to departments on a cost-sharing basis.  Interested departments should contact Andrew Laurence (x43966) to discuss options.

Autorun is a Security Risk

July 28, 2011 by Isaac Straley

autorun

There is a feature in the Windows operating system, autorun, which on the face of it seems sensible and useful.  When you attach removable media (CD, DVD, USB key, etc.), Windows will look for a file with instructions on what to do with it, such as which program on the device to run.  This makes installation of software simple (insert the DVD, a screen comes up giving you a variety of options including “install”) and autorun can be used for other handy actions.

However, today autorun is being exploited by the makers of malware to put harmful software on your computer.  It is now considered prudent to disable this feature of Windows.  Microsoft has released security updates to all recent versions of Windows to enable end-users to turn it off, and has published a knowledgebase article with instructions how to install the security update and then disable autorun.  If the technical details get in the way, there is a one-button “Fixit” in the knowledgebase article which will download and run a wizard to turn autorun on or off for you.

Computer and Network Security Testing

June 6, 2011 by Isaac Straley

Vulnerability Assessment is a valuable portion of an overall process to ensure the security of hosts on a network.   OIT provides software and services to the campus to assist with the vulnerability assessment process.

Usually done hand-in-hand with risk assessment (i.e., the potential loss to the University in the event of unauthorized access), vulnerability assessment at UCI can be applied to a single system or a group of related computers.  Items to check in such a vulnerability assessment include directory and file permissions, user account and password policies, and current operating system patches.

Some tools are available at no cost to interested individuals to download and employ such as Microsoft’s Baseline Security Analyzer.  Other tools require specialized expertise, such as McAfee Foundstone which OIT licenses.

In addition to scanning a computer internally for vulnerability, OIT can assess the security of a computer’s configuration from the point of view of the network and remote users. Items to check in a network based vulnerability assessment include installed and running services, and local firewall settings.

More information is available at the OIT Security Team’s Vulnerability Assessment page.

License Microsoft Software with UC-MCCA

March 30, 2011 by Bob Hudack

Microsoft Office

Popular Microsoft software is available at reduced cost to UCI through an agreement between UC and Microsoft, the “Microsoft Consolidated Campus Agreement” or MCCA.

The MCCA agreement is an annual lease rather than a standard outright purchase, and cost is based on a unit’s employee count rather than the number of computers that will run the software.

There are over 65,000 Campus Agreement Participants enrolled throughout the UC System. At UCI, the Merage School, OIT, ICS, UCI Libraries, Health Sciences, Soc Eco, Arts, Housing, Bio Sci Dean’s Office, Engr Dean’s Office, Law, A&BS, and others have enrolled.

While a careful analysis of your individual situation is always recommended, units which have more computers than staff (say, a computer lab) or units which want to be running the latest release of a package are likely to find MCCA an attractive alternative.

Participation in MCCA is subject to an open enrollment period which ends this year on May 6.  Contact Bob Hudack at x46759 or rjhudack@uci.edu for help in determining if this program will help your unit.
