What files should be compressed?
Any infrequently-used files should be compressed. In Unix and MPE, a daily or weekly batch or cron job can handle compression automatically. The SafeCapacity program for Windows NT/2000 is used to set policies that determine when compression of online files occurs and what files get compressed. Compressing infrequently-used files will allow more data to be kept online, making it simple to access at necessary times.
