Here’s a question for you, my fellow Dopers…
Lets say you run your own small business (lets say a Bacon Salt packaging/redistribution company), you have a small staff, a couple of salespeople, graphic designers and the like, and you have a couple computers which store critical business data, and graphics files for your business
you have no I.T. department
Who’s responsibility is it for maintaining your computer system, backing up your data, and testing the backups for integrity, and having backup hardware in case of a hardware failure?
here’s a clue, it’s NOT the technician at the repair facility, it’s YOU, it’s YOUR responsibility to perform regular backups, make sure the backups are good, and have spare hardware on hand, so in the event of the INEVITABLE hardware failure, you can fall back on your backup hardware, minimizing downtime, or in the event of software corruption, lets say, due to bad blocks on the hard drive, you can restore from your last known good backup
I’ve been dealing with a small business customer over the past couple of days, that brought in his laptop because his hard drive was “making bad noises”, and he had NO backups
it turns out that his hard drive has a failing hard drive platter bearing, and bad blocks on the hard drive (85+ bad blocks), and, of course, predictably, he has no backups
I had to attempt to extract the data off his drive (which took over 5 hours) and got a good percentage of it, but was not able to get it all, I notified the customer of this, and told him it was very likely there was still corrupted data on the drive and i had gotten as much as I could, but could not vouch for it’s integrity, due to the bad blocks, I recovered what I could, replaced the hard drive, reinstalled the OS and restored from the backed up data
And yes, the corruption was still there, nothing I could do about it, since the customer did not have any known-good backups, I could only work with the corrupted data
trying to get the customer to actually understand this, OTOH, has been nothing but a headache, he does not understand that simply reinstalling the OS will NOT fix data that was corrupted in the first place, if you run your car into a tree, putting new tires on it will not fix the pre-existing damage…
and somehow, this data corruption is “our fault” somehow?!?
uhh, exqueeze me, I don’t think so, YOU supplied the corrupted data, YOU had the machine with the dying hard drive, YOU failed to perform regular backups, and YOU do not have any backup hardware to use while i was repairing the machine, constant pestering does not get your machine done any faster, if you want to see the source of the problem, I suggest you find the nearest mirror and look into it
and don’t come whining to me about the “high cost” of your repairs, i actually could have billed you for more hours than i did, as I put at least 5 hours of actual work into this machine attempting to recover the data multiple times due to bad-block related failures
the least you could do is take my recommendations to heart about having sufficient backup hardware and performing data backups on a regular basis, it’s not that hard to back stuff up, especially with Mac OS 10.5’s “Time Machine” software, which works brilliantly, BTW, there’s no excuse not to have stable, safe, usable backups
and stop trying to blame us for your damaged software, it was your lacidasical, lazzies-faire attitude towards data backup in the first place that caused this problem, maybe if you had spare backup drives and actually performed data backups, you wouldn’t be dealing with this headache
oh,and since you have a small company with no I.T. department, guess what, it’s YOUR responsibility to insure your data security and safety
here’s a clue, ALL hard drives will die, ALL of them, it’s not a question of If, but WHEN, hard drives are one of the few components in the machine with moving parts, and the tolerances of those parts is phenomenally small, they’re a problem waiting to happen, if you’ve learned anything from this experience, it’s that hard drives cannot be completely trusted, your data is nothing more than magnetic pulses on a rapidly spinning platter, you need to plan for the inevitable hard drive failure, and part of that preparedness is having backup hardware, performing backups on a regular basis, and having backups to your backups
redundancy is key, let me repeat that, redundancy is KEY
If you learned anything from this experience, I hope you can take at least two points from this experience…
backups are critical
hardware and software redundancy is vital
