File system Layout
The primary task in restoring this system is to duplicate the original filesystem. After installing the base operating system, establishing the network connectivety and installing security patches the original contents of these filesystems can be restored in place from tape.

The size is based on allocating 3 Meg of storage per user. This space is little used by alumni users but is there if required for publishing personal hompages etc. Also, the '/var' filesystem is a separate 'slice' and is allocated somewhat more than the usual amount of space. This was done to ensure that the alumni users would have ample space for mail. Again this is not being used to any great extent but is designed to accomodate a theroretical capacity limit that could be required.
The other file systems reflect the nature of the machine. That is, as an e-mail host. Currently there are no compilers installed and very little extra system software. The primary servers used are POP and WWW.

To restore this system would be straight forward. Providing good backup tapes exist. The first step is to aquire and assemble equipment that matches the previous system as close as possible. Duplicating the file systems during the OS install to match the original layout. Restoring the user community, mail spool and various files such as the passwd file. Below is an outline of how this process might occur.
To create a replacement system from scratch will involve the following steps each of which will be documented in detail later in this document.
1) Aquire replacement component parts ( as detailed above) 2) Determine suitable site for assembling replacement system. 3) Put together the replacement system. Hardware. 4) Establish base operating system and network capability. 5) Restore file system layout to match old alumni system. 6) Restore directly from tape file systems from previous system. 7) Test and evaluate to see if all systems are in place.
I. Replacement Hardware.
Follow procedure outlined in the SSE for submitting detailed replacement parts request. Perform all administrative tasks required to get replacements expidited from SMCC. II. Establish New Site. Consult Disaster Recovery Coordinator for site assignment. Submit required space and power requiremnets. III. Reconstruct Hardware. Upon reciept of hardware, unpack and assemble components at the new site. Retain all paperwork, shipping info etc. IV. Bring up base system. 1. Establish a base operating system environment to match prior system. If the new system ships with an OS newer than the previous system. Locate and install the system that had been on previously installed. (e.g. Solaris 2.4 vs. Solaris 2.5) Then do an upgrade if desired. 2. Install patches (current reommended patches) 3. Install current recommended security software. As outlined in documentation written by Peter Laws regarding the latest recommended security steps to establish for a secure Sun system. 4. Coordinate IP# and DNS entries with NWS to recreate the 'alumni' hostname. V. Recreate filesysems. 1. Using the preferred restore method (UFSrestore See DRPWWW02) restore individual filesystems that are not related to system operation (e.g. /export/home1) such as the user community. 2. Restore individual configuration files on a one by one basis. The password files /etc/passwd /etc/shadow are examples of this sort of file. There will be numerous files of this sort outlined in another section of this documnet.
