Introduction to UIC's ADSM Network Backup Service
This article provides an introduction to UIC's ADSM Network Backup Service.
Backup your campus server over the network, unattended. Retrieve files inadvertently erased or recover from hard disk failure. Do this before you lose files.
Spectrum Protect software supports all modern versions of Microsoft Windows, Apple Mac OS, Linux, and many obsolete/older versions and operating systems also.
What does ADSM stand for? Originally it stood for ADSTAR Distributed Storage Manager, which is what IBM called the software it used. The software was then renamed to TSM (Tivoli Storage Manager) and is now called IBM Spectrum Protect.
What is the Network Backup Service?
Network Backup Service is a utility to backup the hard drive on campus servers (Windows, Mac, or Unix) when it is on the UIC campus. Usually, one would have to buy a spare drive or use other backup tools to backup your hard drive. ACCC, however, offers the network backup service for campus servers free of charge. This allows you to backup your drive over the network on servers that we maintain. If you ever accidentally delete a file or experience a hard drive crash, you can restore the missing information from the network backups.
You can easily set up automatic network backups to run every night or request to have the automatic backup run during the day.
How Many Backup Copies Does the Network Backup Service Keep and For How Long?
- The Network Backup system keeps up to 14 versions of each file.
- The current version of an existing file is kept as long as the file exists.
- The non-current versions of a file are kept at most 30 days; they are deleted either (1) when the backup service has to make a new backup copy and there are already 14 versions of the file in that file, or (2) when 30 days passes.
- The last version of a file that has been deleted is kept for 60 days after it is deleted.
- There is more; the Download Your Client page has a full of the network backup policies.
This is of particular importance for files that change daily, the most common of which are email inboxes. This means that Spectrum Protect now has copies of your email folders on your computers going back two weeks. It does not apply to email on GoogleApps@UIC or on Exchange
You can now see these versions on systems where you can get a shell session (any type of Unix on your desktop) by specifying the -pick -inactive switches on the dsmc restore command. On GUI systems (Windows and Mac), you can see them by clicking View then Display active/inactive files.

Who Can Use the Network Backup Service on Their Personal Computer, shared departmental PC, or server?
- The Network Backup Service is only available for use on campus servers.
- Given the high volume of data that is transferred when using it, the Network Backup Service can not be used from off-campus or from any type of outside connection. It may be used only with ethernet or UIC-Wireless connections on the Chicago UIC campus. The huge amount of data transferred during network backup makes it unusable over modem connections, or any type of DSL or cable TV connection even if physically located on campus.
- Back up only your files and documents, not scratch directories and not operating systems or software files that you can get back by re-installing. (The default options files provided with the ACCC client software is already set up to do this.)
Warnings about the restriction to backing up only one machine.
(To clarify: It is OK for your computer system to have multiple hard drives, as long as they are all used by one operating system image, but it is not OK to install Linux in a separately bootable partition, or to run Windows in Wine on a Mac, on the same machine and then back it up using the same Spectrum Protect account. In these cases, ask for a second account)
Note: We do not support the Archive function of the Spectrum Protect system and we have no plans to support it in the future.
Checking on the Status of Your Backups
The ACCC Status Web utility shows you when the last time you successfully backed up using the Network Backup Service and which allows you to sign up for daily automatic email messages to keep you up to date with this information. Type your email address in the box in the Watcher column to request the email message be sent to you.
