Backup Data on Floppy Disk in UNIX

This chapter describes how to backup data on a floppy disk. Help on how to restore data can be found under Data Restoration.

Note:

• The data backup on the operating system level should only be applied if the Data Backup via the MICROS Retail OSCAR POS Menu System is not possible.

Carry out a data backup as follows:

1. Change to the directory /usr/oscar/osc<Datum>/work.srv.
2. Create a new directory with the name daten by entering mkdir daten.
3. By use of the command copy *.DAT /usr/oscar/oscDatum/work.srv/daten you copy the data to be moved to the new directory daten
4. By use of the command copy *.IDX /usr/oscar/oscDatum/work.srv/daten you copy the indices to the new directory daten
5. Then change to the directory daten by use of the command cd daten
6. Create a tar archive by use of the command tar cf <Name>.tar *.*
7. Compress the tar archive by use of the command compress <Name>.tar
8. Copy the archive to floppy disk: tar cv6 <Name>.tar.Z
9. You can now delete the directory daten. In order to prevent queries you should sign on as a superuser (su <RETURN>, Password). The deletion procedure is to be carried out as follows:
   cd ..
   rm -r daten
   exit

Note:

• All UNIX commands are case-sensitive.
• <Datum> in a directory name stands for the release date of the MICROS Retail OSCAR POS software.
