Database Backup and Restore
There are at least two database files that need to be backed up weekly (or in the case of large cal-
ibration volumes, daily) to avoid data loss in the event of database corruption or hardware fail-
ure. Ideally the database files should be stored on a network share that is backed up nightly. This
would eliminate the need to manually back up each of the files. If a network drive is not avail-
able, the database can be backed up to the built in DVD burner or CD ROM drive, a removable
USB drive, or portable CD ROM drive. You can rename the database files or create new files if
they become too big.
The following are the two database files:
• Electronic Test Equipment (ETE) database, equipment.mdb. The ETE database contains re-
cords of the test equipment model numbers, serial numbers and calibration dates.
• Device Under Test (DUT) database, dca.mdb. The DUT database stores the model numbers,
serial numbers, pass/fail status, test limits, and test sequences.
To backup the ETE and DUT database
1 On the test system PC, close the "Lightwave Division" test executive software application.
2 Using Windows Explorer or My Computer, locate the subdirectory folder c:\lwdcal\data.
3 Select all ".mdb" data files that you wish to have backed up. This includes the files
equipment.mdb, dca.mdb, firefly.mdb etc.
4 Copy the files to one of the backup medias as mentioned above.
To recover a database
1 Exit all applications.
2 Copy the database files from the backup location to the following disk drive folder:
