Have you ever lost a file? I mean, it was there one day and gone the
next?! How would you like to never lose another file again? Read on...!
Technology Secret #8
Backups Don't Work
There
are four main problems with tape backups.
-
Most of
us don't keep our backups current.
-
It takes
too long to find a missing file on tape, and too long to restore it.
-
Over the
long run tapes and tape hardware become expensive.
-
Most users can't restore a file by themselves.
Most
companies
don't keep backups current. The sad truth is that we don't do as
good a job as we should keeping our backups up-to-date. Yet we rely on them to save
us
when a disk drive fails or we accidentally delete an important file! Backup jobs fail, we don't test our Restore
procedures, tapes go bad over time...
But even if we do keep everything current, it takes too long to find
a missing file on the
backup tape. First you need to find the right tape. If it is
offsite, you need to retrieve it. Then you hope and pray that the
catalog or index of that tape is accurate. If it isn't, you're going
to have to rebuild a listing of every file on the tape. Then you need
to make sure that the file is readable, recoverable, that no damage has
occurred to the tape or file. Then and only then can you restore it.
Usually, this process cannot be done by the person that lost the file
-- a System Administrator is required -- adding to the expense, complexity,
and time required to restore one little file!
I've seen this process take ALL DAY.
What happens if you are dedicated about making regular backups? As your business
grows your data will grow. As your data grows, your backups will
grow...from one tape per backup to two...to three... So you buy bigger tape
drives and more media and the cycle just continues.
Soon you
might want to invest in a tape changer. Do you know that they are
unreliable? A friend of mine once bought a very expensive tape
changer ($25,000) that eventually had to be removed and replaced with a
competitor's unit. The months of problems and stress caused by this bad hardware
was enormous.
Here's another problem. In the Microsoft world, a tape created
on one tape drive must be read back by an identical tape drive using the
same backup program that created the tape! Don't try to restore an
old tape on a new tape drive...
Can I tell you a better way? What is needed is something
ONLINE, AUTOMATIC, and EASILY ACCESSED by anyone in your company.

Secret #9
Use Your Tape Drive For Disaster Recovery,
Use Hard Drives For Backups.
First,
let me explain the difference between Disaster Recovery and Backups.
Backups traditionally are tape archives. The archives are
created by copying data stored on hard drives to a tape. The tape
contains a (usually compressed) copy of the hard drive data. Backups
are used to restore files that have been inadvertently deleted.
Disaster Recovery, on the other hand, is a large, multi-faceted
project. The goal of Disaster Recovery is to maintain business
operations in spite of a flood, say, or a tornado or fire.
Tapes are ideal for DR because they may be carried to an offsite
storage location for safekeeping. (We have full copies of our clients'
archives here in my office for just this purpose. Call us at (302)
999-1899 if you need
this service.)
Tapes are cumbersome, as we saw above, for recovering a single file or
folder. A much better system is online storage -- an extra hard
drive (or several) that contains an accurate copy of your corporate data.
Let me draw you a picture.

This
simple diagram is typical of many businesses. The server contains the
corporate files used in day-to-day operations. The server also may
have a built-in tape drive used to make backups. (In some companies, a
dedicated machine is used for backups -- a practice we recommend.)
Notice the disk labeled 'Copy' on the server above. This disk
is just what is says it is. A copy of the data stored on the other
disk. If one disk fails, you still have the other.
There are a LOT of ways to achieve
this level of data integrity. We can mirror disks, write a nightly batch job to copy files from one disk
(or PC) to another, or create a dedicated backup system. Each
situation is unique -- you can learn more right here, or call us to maximize your protection immediately.
What is a dedicated backup system? Let's say you buy a new PC
to replace a slower model. You can take that old PC, install a whopper
of a hard drive (for about 100 bucks), and use it to maintain a copy of your
corporate data.
Give us a call so we can plan your upgrade. Empower all of your
users to recover lost files without the use of tapes or backup
software! Abolish dependence on the System Administrator -- believe
me, he'll thank you for it! You can reach us at (302) 999-1899.

Secret #10
Use Linux For Data Protection
Instead of Windows Backups
Linux
leverages your hardware dollar.
Remember the slower PC we just upgraded? Red Hat Linux will run just
fine on this machine. And your Windows users will see this machine
just like every other Windows system on your network.
Backup Scripts are POWERFUL. Once written, they run and run and
run and run... Each of your systems can be protected -- there are
NO extra licenses to buy, NO extra software to install, and NO
extra administration required.
Reduced costs, short and long term. In the short term, you save
the capital expense of top-dollar Windows programs and operating systems
and the high-end hardware needed.
In the long run, you save MUCH money by increasing productivity of your
workforce and reducing administration expenses.
Call us to learn how to exploit Linux technology. Gain some
understanding into what Linux can do. You CAN break free of the "lost
file" headache. We're here to help.
