File Backup via Menu
The
following program description deals with:
A
file backup can generally be carried out from the operating system level, but
it is started from the MICROS Retail OSCAR POS menu by default. Open the window File Backup via System. There are four input or selection fields available by
use of which you can determine the data to be saved and the data medium.
After
making the entries described further below, click on the Start button to start the file backup. A
window will then open in which the currently saved data will be displayed. Make
sure that an appropriate Data Medium has
been inserted before the start.
Notes on file backup on floppy disk:
- The number of floppy disks needed for the file
backup depends on the quantity of data to be saved. The MICROS Retail OSCAR POS
application prompts the necessary disk change with "Please insert Disk 2 (3, 4 ...) + Ent".
According to the message, insert the next disk then and confirm by
pressing the Enter key. Any data on the disk will be overwritten. Label
and enumerate the disks to avoid overwriting your data by mistake.
Four
input fields are available in the area of file backup.
Three
(in UNIX) / zwei (in Windows NT) options are offered by the MICROS Retail OSCAR POS application:
- From Working Directory (UNIX and Windows NT)
All *.DAT- und *.IDX files of the directory work will be saved.
- Server Database (UNIX und Windows NT)
All *.DAT files of the directory work.srv will be saved. The directory
name will be displayed, too.
- Whole MICROS Retail OSCAR POS Directory (UNIX and
Windows NT)
All directories incl. all files from MICROS Retail OSCAR POS will be saved.
The
following selection options or available:
- To Streamer Tape
Select this option if you carry out the
backup by use of a streamer. This option is the most frequently used one,
- since a tape contains a large memory capacity
- and offers actual data security as an external
data medium, even in cases of a hard disk defect.
- To Floppy Disk
The memory capacity of a floppy disk is limited. Therefore it should only be used
for the backup of small quantities of data.
The MICROS Retail OSCAR POS application checks for the correct floppy disk format
automatically. If it does not correspond to the format required by the
operating system, the floppy disk will be formatted.
Note:
If your MICROS Retail OSCAR POS application is installed on a UNIX system,
the data will be stored in CPIO format. Please consider the commands
related to the format, e.g. for checking the saved files.
The system assumes 3,5" disks with a memory of 1.4 MB. Compare the
notes on Capacity.
Just like the streamer tape, the floppy disk offers data security in cases
of a hard disk defect.
- To Archive File
If you choose this option the files to be saved will be copied to a
separate directory. The path and name of the directory will be determined
via the Name of the Archive File.
Please note that in cases of a hard drive defect, these data could be
affected.
An
entry in this field is only possible if you selected the Archive File to be the Data Medium. Enter the path and the
directory name.
Enter the capacity of the data medium in
this field. Depending on the selection, there might be already a predefined
value. For example, if you choose the option “floppy disk”, the field will
display 1440 (= 1,4 MB Disk). The value can be edited. Please note that
the unit of the values displayed or to be entered is KByte. The actual memory
capacity of the medium can be found on the medium’s label. If you choose to
save your data in a Working Directory,
you do not have to enter a capacity value.
If
the value displayed by default does not equal the value of your medium, you can
edit the default value:
- Enter the directory /usr/oscar/oscar.d/fgl
- Open the file runBackup.fgl
by use of an editor (in UNIX e.g. scoedit runBackup.fgl). Make sure the
spelling is correct (case-sensitive!!).
- Use the search function to search the character
sequence "LET
capa" and replace the value that follows this entry by
the desired memory capacity.
Example:
Old: LET capa = 120000
New: LET capa = 240000
- Save the changes and close the file.
