Hard Disk Failure? What Next?

Laserdyne S94PFailure of a hard disk is bad enough. However, it is much worse if you do not have a backup to use in getting back into operation.

A hard drive backup can be done at several levels. The most extensive backup is to create an image (also referred to as a ‘ghost’) of the hard disk drive (HDD) using a software application such as Acronis or Norton Ghost. Note that creating this backup may require the services of an IT specialist.

Acronis is one of several software applications available from retailers. It is also the one used by Prima Power Laserdyne to create HDD images. Creating an image has the benefit of backing up the operating system (OS), software applications, and all data files contained on the HDD.

Laserdyne Backup Utility

A less thorough, but easier to perform, backup which can be completed by the machine operator uses the Laserdyne Backup Utility. Note that this backup does not include the operating system or work files.

When using the Laserdyne Backup Utility there are three backups available: full backup, mini backup, and data backup. The full backup includes all files necessary to configure and operate the system (except that it does not include the OS). The mini backup includes all essential system files, but omits non-essential files to reduce the backup size. Meanwhile, the data backup includes only system data.

How often should you create a backup?

The hard drive should be re-imaged at least yearly. The Laserdyne Backup Utility should be run more frequently. The full backup should be done semiannually (two time per year) while the mini or data backup should be done monthly or whenever system files are changed.

Additional information on the Laserdyne Backup Utility can be found in the User Interface Section of the Laserdyne System 94P Operation and Programming Manual.
