System Maintenance
Backup
It is recommended that you have a regular backup strategy. Your IT department may
already have a backup strategy in place which is suitable for the test set and its data.
Using the Agilent Recovery system in conjunction with a regular backup strategy should
allow full recovery of the test set data.
The Windows operating system has a Backup utility that you can use to archive files and
folders in case of a hard disk drive failure. See the Microsoft Windows Help and Support
Center for more information on this utility. You can also use third party backup utilities.
However, you must ensure that this third party software is compatible with the test set's
system software. See “Customer Installation of Software" on page 43 for more
information.
When performing backups, we recommend that you backup the data to an external
storage device connected to the network or one of the test set's USB connectors. Also,
you should perform backups at times when the test set is not being used for normal
operations as it may impact the test set's overall performance.
System restore
Windows contains the capability to restore the system to a previous point in time.
System Restore is enabled with default settings as provided by Microsoft. However,
System Restore is not 100% successful. Therefore, it is not the recommended method to
backup the test set. System Restore has not been tested to verify successful restoring.
Disk defragmenting
Over time the hard disk on the test set becomes fragmented. Windows has a Disk
Defragmenter utility that you can use to defragment the hard disk. See the Microsoft
Windows Help and Support Center for more information on this utility.
Running Disk Defragmenter should be performed when the measurement
application is not running. Measurement throughput is significantly
impacted while disk defragmentation is in process.
