[labnetwork] System backups

[Hughes, John S]

Hello Tony,

As per your suggestion, I asked our IT folks to look into getting SSDs to use as backups for a lot of our process tool computers. We have quite a few "legacy" systems, and the question they asked me was: where can we get an SSD drive with an IDE connection and <2GB capacity, since some of our older systems can't handle the high capacity drives.

If you, or anyone else, knows of a good vendor for such drives, I'd appreciate hearing about them.

Thanks
John

Hello Keith;

Great topic.

We had similar concerns. Some of our equipment use DOS
and the computers that came with the system could only accept
a limited size of hard drive, which you can not buy anymore.

When a hard drive failed we tried buying old recycled hard drives but
found they did not last too long. And we could not replace all the old
computers with a new one since some systems might need an ISA slot.

The solution we found was to use smaller solid state drives.
That way we could keep our legacy computer. This has worked
so well that we make back ups of the whole drive and copy it on
to another solid state drive. This spare solid state drive can then
be swapped out when the original hard drive fails. Minimum
equipment down time.  Only thing is that the back up work needs
to be done before you have problems. Making regular backups
from time to time helps, that way you do not lose to most current
recipes.

They make them in many sizes and configurations, IDE, SATA, and USB.

For backing up the drive I like to use an IDE to USB adapter and
plug that into the normal desk computer. From there you can
mirror or ghost the drive, or even store it on a remote server and
then copy it to the new spare solid state drive.

Regards, Tony W.

We have 35 computers running systems in our clean room.

Stuff like the Ellipsometer, PECVD,Etchers, SEM, three different RTA's, Furnaces.

How do you back up and protect all these systems from a disk failure?

We use WIN95, 98, and XP....whatever the manufacturers were using when they wrote the operating software.
