Overview
TRANSFERRING
HISTORICAL DATA ONTO
DISKETTES
Archiving is the process of copying historical data from the hard disk to
diskettes. You need to archive data when the hard disk begins to run out of
space and you want to save your old files. You should archive data once a
month to keep the system running efficiently.
This section discusses how to archive data and contains information about the
directories and files CMS uses. It includes procedures for copying the system
tables and historical data files to a diskette with the MS-DOS copy command,
and for erasing these files from the hard disk with the MS-DOS erase
command. This section also tells you how to restore archived data to the
hard disk so that you can print historical reports.
To print historical reports from archived data, you need the system tables and
historical data files for the days in which you're interested. The system tables
file contains the information that identifies the lines, splits, and agents for
which historical data have been saved. Up to four historical data files and
one system tables file fit on a single 360K 5 1/4 inch diskette. The 1.44MB
storage on a 3 1/2 inch diskette increases that storage four times.
If you are using a 6300 WGS, you'll be backing up onto 3 1/2 inch diskettes; if
you are using the PC 6300, you'll be backing up onto 5 1/4 inch diskettes.
To clear space on the hard disk, you can simply erase your oldest files;
however, if you want to save the data for possible future use, you should
archive those files to a diskette first, and then erase them from the hard disk.
Copy the four oldest data files and the oldest system table to the diskette.
After you verify that the files were copied, erase those files from the hard
disk.
If you archive files on a regular schedule, such as once a week, you can avoid
running out of space on the hard disk.
