So you either forget to qualify your answer,
I didnt forget anything, child.
or it's a "I wouldn't but it's ok for someone else", situation?
Wrong, as always.
Taint a theory, child.
so you make these backups on a file by file basis,
Yes, with the most critical stuff. Not to protect against
hard drive death, but because that is desirable for other
reasons, so its easy to backtrack when I have started to
modify some code and have discovered a damned good
reason why the approach has a serious downside etc
that I did not anticipate. That AUTOMATICALLY provides
complete protection against hard drive failure too.
or at least are seeming to suggest either
this or that everyone is running RAID arrays.
You need to get your seems machinery seen to, child.
I used the word mirror for a reason.
We both know neither of these are happening in many cases.
Irrelevant to whether there is any point in replacing physical
drives at some rate you have plucked from your arse WHEN
YOU HAVE ENSURED THAT YOU CANT LOSE ANYTHING
THAT MATTERS IF A HARD DRIVE DOES FAIL.
You continue to overlook system downtime.
Lying, as always. I HAVE SAID REPEATEDLY THAT THE FAILURE
RATE I SEE WITH HARD DRIVES IS SO LOW THAT SYSTEM
DOWNTIME ISNT SOMETHING THAT MATTERS HERE.
I get vastly more system downtime from just reconfiguring systems
as I change what I am doing on a particular PC over time etc and
other stuff like the mains power not being available for hours etc.
Even on a personal PC, it is inconvenient to have to restore a backup
Wrong when that has never actually been necessary over decades now.
MORE DOWNTIME IS INVOLVED WITH REPLACING THE HARD
DRIVE ON SOME CALENDAR BASIS THAT YOU HAVE PLUCKED
OUT OF YOUR ARSE WITH NO EVIDENCE THAT THAT PARTICULAR
FREQUENCY IS THE APPROPRIATE ONE, WHEN THAT REPLACEMENT
IS ACTUALLY INFINITELY HIGHER THAN I ACTUALLY SEE WITH
FAILING HARD DRIVES.
or swap in another RAID member contrasted with the replacement
at another time, when it's convenient and before the old drive fails.
The whole point of true RAID, where the R actually means redundant,
is that you get to replace the failed hard drive when its convenient, child.
Your ideal is not seen in reality,
Wrong again. It is here, child.
and it still doesn't counter the downtime
from failure, the time to restore backups,
WHICH IS MUCH LESS THAN THE DOWNTIME AND TIME
TO RESTORE THAT IS INVOLVED WITH MINDLESSLY
REPLACING THE HARD DRIVE EVERY 4 YEARS, CHILD.
or the loss of performance from continuing to use an old drive.
Just another of your pathetic little pig ignorant fantasys.
I replace drives when they become too small, AT A HIGHER
RATE THAN YOUR STUPID 4 YEARS THAT YOU HAVE
PLUCKED OUT OF YOUR ARSE, so I get BETTER
performance than I would get if I left the replacement for 4 years.
And when I reused a drive that was much older than 4 years
on another PC where that drive was plenty big enough, and
discovered that the boot time of that system was irritatingly
slow, I replaced it with another that was also older than 4
years to get a better boot performance. The machine is
rebooted infrequently enough that it wasnt worth buying a
new drive for since it was always an interim config which
has been entirely replaced with a wireless laptop which
give much better instant on than that system with a brand
new hard drive could ever have, and the much more
convenient portability that a wireless laptop brings with it.
Of course it does matter.
Nope, NOT WHEN THE DOWNTIME NECESSARY TO CHANGE
THE HARD DRIVE EVERY 4 YEARS IS MORE THAN THE
DOWNTIME SEEN DUE TO HARD DRIVE FAILURE.
While it may not be hundreds to thousands of dollars loss,
we're not talking about high expense to replace the drive
either, again it is possible to get one for $40 and divided
by # of years used, quite inexpensive.
STILL NO POINT IN INCREASING THE SYSTEM DOWNTIME
TO SWAP THE DRIVE WHEN THE DOWNTIME SEEN DUE TO
HARD DRIVE FAILURE WILL BE MUCH LOWER.
INFINITELY LOWER IN FACT WHEN MOST PERSONAL DESKTOP
SYSTEM NEVER ACTUALLY SEE A HARD DRIVE FAILURE.
The only thing that makes any sense at all is to
have full backups of anything that matters, so its
a complete yawn if the hard drive does actually die.
"A config"? Which magic config is that Rod?
Nothing magic about it, gutless.
Hot-swap SCSI or SATA perhaps
No perhaps about it, child.
but you are the one already citing costs.
Hot swap SATA doesnt cost a cent more, child.
Anything else and the time to restore
data is still downtime from use.
PITY ITS MUCH LESS THAN THE DOWNTIME YOU SEE IF YOU
ARE STUPID ENOUGH TO SWAP THE DRIVE EVERY 4 YEARS.
A nice vague theory until examined more closely and contrasted
with the trivial cost of drive replacement before they fail.
PITY THAT THE DOWNTIME INVOLVED IN MINDLESSLY SWAPPING
THE DRIVE EVERY 4 YEARS IS VASTLY HIGHER THAN THE
DOWNTIME ACTUALLY SEEN DUE TO HARD DRIVE FAILURE.
So do you continue using these mirrors after drives have failed,
until it's no longer a mirror, OR, do you replace the failed members
ONLY IF THEY DO ACTUALLY FAIL, CHILD.
and see that DOWNTIME you pretend doesn't exist.
Lying, as always.
Downtime doesn't have to mean system is unplugged and all
internals spread everywhere, only being down (from intended use).
You quite sure you aint one of those rocket scientist gutless lying children ?
THE DOWNTIME I SEE, HOWEVER YOU DEFINE THAT, IS
VASTLY LESS WHEN I REPLACE HARD DRIVES WHEN THEY
FAIL THAN I WOULD SEE IF I MINDLESSLY REPLACED ALL
HARD DRIVES ONCE THEY GET PAST 4 YEARS OLD.
Your mirror covers that?
Yep.
WHICH IS HIGHER IF YOU MINDLESSLY REPLACE ALL DRIVES
ONCE THEY GET OLDER THAN 4 YEARS OLD, INSTEAD OF
REPLACING THEM ONLY WHEN THEY ACTUALLY FAIL.
YOURS IS THE HIGHER COST APPROACH.
which was one of the reasons you'd already cited.
Lying, as always.
Granted, it does cause downtime to replace the old drive too
Funny that. AT A MUCH HIGHER RATE THAN REPLACING
THE DRIVE WHEN IT DOES ACTUALLY FAIL TOO.
but with one important difference, that it's
scheduled at the convenience of the user.
Completely academic with the failure rate of hard drives actually
seen with properly configured personal desktop systems.
Yes 4 years is somewhat arbitrary,
Plucked out of your arse.
some companies do it every two, or three, but none wait 5 AFAIK.
Plenty dont bother to swap on a calendar basis.
4 years also factors for cost per year.
Waffle.
It's about weighing risk against cost.
AND WITH PERSONAL DESKTOP SYSTEMS, THE COST IN
DOWNTIME AND HARD DRIVE EXPENSES IS ACTUALLY LOWER
IF YOU ARENT STUPID ENOUGH TO MINDLESSLY SWAP DRIVES
AT SOME RATE YOU HAVE PLUCKED OUT OF YOUR ARSE.
If we want to be thorough, sure, if your drive is 6 years old instead of 4
I do still recommend replacing it before it fails rather than as a result of it.
No one actually gives a flying red **** what some fool like you 'recommends', child.
Some of us have been doing this stuff before you were even born, child.
And have enough of a clue to have noticed that the downtime
involved with adequately backed up personal desktop systems
is actually LOWER if you dont mindlessly replace hard drives
on some calendar basis that you have plucked from your arse.
