Merging Databases
The Merge Database function is designed to add tests from a backup source to the tests on the hard
disk database (the destination). One disadvantage of the Restore Database function is that it erases
all the patient tests on the hard disk and replaces them with the patient tests from the backup
source. If some tests found on the hard drive are not on the USB storage device, backup floppy
disks, or network file server, these test results will be lost.
The merge database feature has the added advantage of helping prevent the loss of patient data by
the inadvertent use of an outdated or improperly labeled backup set. No tests are deleted from the
hard drive.
Merging two databases can be a lengthy process. If your backup source contains 10,000 patient
tests, it may take up to 75 minutes to merge the backup database with the current hard drive
database.
Note: If your HFA II-
i
suffered a hard disk failure that could not be repaired by the previously
described methods, you will not be given the opportunity to use the Merge option. You will need to
use the Replace procedure.
To merge a backup database with the current hard disk database:
1
From the File Functions screen, select BACK UP/RESTORE.
2
Choose the Source of the backup database (USB storage device, file server, or floppy), and the
Destination (Hard Drive). Select PROCEED.
3
A pop-up window will appear giving you the option to replace the
current hard drive database with a backup database, or merge the two
databases. Choose MERGE.
4
Insert the backup USB storage device or first backup floppy disk,
and select OK. A popup window with the phrase “Restoring from USB
storage device/floppy/File Server” and a progress indicator will appear.
The HFA II-
i is analyzing the disk to determine how long it will take to
merge the two databases.
