When compressed, the size went down to 1,948 bytes.

For example, a simple, black-and-white Windows Paint file (BMP) I created took up 812,086 bytes of disk space. So rather than having data always expanded and taking up valuable disk storage, it makes sense to have infrequently-used data be readily available, but in a compressed format.Īlso, some file types are inefficient. It's doubtful that most of us really use all data that's available to us on file servers or on our local hard disks. The second reason that compression is needed today is for efficiency.

Remember the days when an entire application would fit on one floppy disk? Now some vendors (including Novell) are shipping their software on CD-ROMs for easier and faster installation. Compression: An OverviewĮven though the price of disk storage has dramatically declined over the past 10 years, the need for data compression has risen due to two main factors.įirst, today's applications require more storage space than in the past. This AppNote explains the internal workings of the first two methods and discusses the impact of using these technologies on your servers. With the release of NetWare 4, Novell has introduced three new server technologies to more effectively utilize disk storage on your NetWare server:
in Stamford, Conn.Įncryption that's built in at the operating system level, which Microsoft includes with Windows, generally works well for protecting files on individual servers, Thompson said. But now, "there is significant interest in compression and encryption at the server level for batch file transfers," said David Thompson, an analyst at Meta Group Inc.
PKZip and similar compression technologies have primarily been used at the client level in the past. "But we are taking that on one client at a time," Knobloch said. Because of that, it has been a challenge to get some of them to accept encrypted PKZip files from Gilsbar. But Knobloch said many of the clients and insurers that Gilsbar deals with have standardized on encryption technologies developed by Palo Alto, Calif.-based PGP Corp. The new encryption functionality has been very easy to implement, he added. With an April 1 deadline looming for complying with the federal Health Insurance Portability and Accountability Act, Knobloch said Gilsbar plans to use PKWare's new software to compress and encrypt all records containing patient health information, as required by the law.
