Thanks! We have 2 raid1 partitions right now, I set of disks has the
OS the other set the data. They are all in removable racks also. all
I would have to do is add some drives. I think I'm going to still do
the rsysnc backup though because I don't want any one to have to
think about doing the backup. But I'm going to talk with him about
teaching him to do a backup to a mobile rack, He is VERY concerned
about data safety, I'll think he'll go for it.

Hi Seth,
Your plan may work for you, but may take extra money for hardware and
suffer
from data transfer or communication problems. It will also take a lot
of
your time and may be a problem when it comes time to restore data.
Look for
something that a non-technical person can do to backup and RESTORE
your
system and its data.
I suggest that you look into using a $20 mobile rack fitted with a
20 to
100GB hard drive for your backups.
My best friend is a dentist and his office has a dozen workstations
connected to a Linux server. He uses a removable 20GB hard drive to
do an
incremental backup every day. He has eight mobile rack cartriges that
he
rotates each day and parks or saves one for a monthly backup. He
takes a
daily backup home and returns to work the next day with an old rack
to be
updated with new files.
We use a simple script and MD5 to do the backup and verify that the
copy is
good. the dentist also benifits by having current patient records and
xray
images at home to help a patient after hours or on the weekend.
Cost is minimal and can be spread over time. We paid about $20 for
the
mobile rack and have gotten 20GB drives for $50 on sale at CompUSA.
We
bought four to start and over time added to them as we needed, up to
about
fourteen now. The dentist has eight for the office. two for his home,
and he
gave me four.
Incremental data backup is quick, about 5 min for daily, or 30 min to
a
freshly formatted empty drive. We scrub or format a removable backup
drive
from time to time and rewrite all files to it.
We keep the operating systems for all workstations on CD-ROM as
Norton Ghost
Images. Two CD-ROMs are made for each workstation, one for office and
the
other is saved off site at the doctors home.
The backup design was to keep system and data separate and have
redundant
backups for office and at home. We wanted to ensure that we could
restore
everything in the event of fire, theft, or hardware failure.
We have used the system for over a year and it works. I have trained
five
non-technical office personnel and the dentist to use the system. We
plan
and do a RESTORE of both workstation and server at least twice a year
to
ensure that procedures work and are known by all. I let the dentist
or his
office manager do all the work and I stand by for questions if
needed.
Mobile racks and cheap hard drives have been good to us. Oh, the
drives
don't need to be fast, we use 5400 RPM. The drives are parked or
offline
most of the time and are used once at the end of the day or if there
is a
thunder storm coming.
Remember, keep it simple so non-techies can do the job, make sure it
works
and several people understand the procedure to make it work.
Hope this helps you think of another way to backup and RESTORE your
system
and data.
