As our Sun system is a cooperative venture, there are no set fees for use of the computing resources. Certain users make very heavy use of disk, processor, network, and printer resources, and they each pay thousands of dollars per year to support the opera- tion. Major users have mutually agreed to pay a share of mainte- nance and supply costs proportional to their share of the use of all the workstations. Compared to these users, your requirements may be quite minor. However, if you do end up using many hours of CPU time, more than a few megabytes of disk space, or print more than a few hun- dred pages a year, your consumption of resources will be noticed.
Many small users contribute to the system by buying printer supply items.
Such assistance is welcome. The system administrator arranges for the regular backup to tape of all home directories. However, scratch directories are not guaranteed to ever be backed up. You should therefore backup your own scratch directories, and you may wish to make your own more frequent backups of your home directory. It is also possible to read and write DOS floppy disks with a Sun.
