Life is full of tools, tips, tricks and technology. However most people fail on the “When to” and “When NOT to” use a particular piece of technology.
For example you would not use a pair of scissors to cut the lawn, or a lawn mower for a hair cut , yet they are both cutting / triming devices !
So why it is we see some people use a full on SQL database to manage the population of a TEN item drop down box and other use MSAccess (and the MSACCESS GUI not a web app) to run a million pound revneue generating mission critical business application for 100 users over 20 sites

Over the xmas break i thought i would review my data backup process, i have a few friends with kit at their house linked to mine via long range WiFi !, so File replication between server seemed like a good plan !
Got some big disks attached to each server using??USB 2, and setup replication, Sorted,
NAH, nothing is that easy,
NTFRS has got to be the most quirky thing ever to setup, my first word of advise, is go for a pint after you configure it, and BEFORE you put any data in the replicated folder. no in fact, that is No 2. No 1 has to be test you infrastructure HARD first.
My 1st snag was a delayed write error on my USB2 disk, which corrupted the USN data for the replicated folder, and completely screwed the whole replication process, after some soul searching, crying, fretting and LOTS of cursing. I reset the entire NTFRS config for that server.
Sorted I though, no such LUCK
another Delays write error, Closer inspection revealed i had been a cheap skate when i added USB2 to my aging server, it had a “VIA” chip, DOH!, DOH!, DOH!, DOH!, DOH!
Quick trip to a local computer retailer?? (not PCWorld), we have a local back street guy who is VERY good,
and i kissed good bye to the I/O issues. This is cool so i thought, all my data became “pre install” and everything seemed to be fine,
This is where the pint comes in, I “moved” (big mistake) my data from the pre_install folder to the replicate folder, and everything looked good, get up the next morning, NO DATA AROOGA AROOGA CURSE CURSE CURSE (BTW this was XMAS day, i have a record of upseting the wife, but tellting her i may have lost all the photos on XMAS would surely top it all)
after a week of searching volume shadows copies and offline data on all my PCs and friends servers, I had successfully recovered ALL our data, (can i have my testicles back now please)
so 1st things first MAKE Copy or three, and try again !
This time i did go for a pint or 3 before “COPYING” in my valuable data, and all i NOW Ok
all the data if almost fully synchronise across the servers, well 150 G of photos and other random data, will take a while to sync over wifi !
Some serious Lessons learnt
1. don’t mess with your home IT on Xmas Eve
2. don’t rush NTFRS config
3. don’t MOVE data when you have the space to copy it

got my self one of those domestic power meters and been around the house,
HOLY COW!!!!
Need to change my storage strategy, the Compaq RA4100 fibre channel chassis with 12 disk may well be over kill, but it is also DAMN expensive to run,
and I have NO idea why the UPS is pulling 100Watts with NO load !!!
??As i am only ising the storage for archive type stuff not “live” apps, I am planning to replce it with an external USB2 disk,
the Cost Recovery Period will be less than 4 months !
Not sure what to do about the server though, it is runnign AD, Exchange, VMware server with VOIP PBX and dansguardian ….
