The device isn't a lot of use without the media, either.
Yep, its obviously the total cost of the hardware and media
that matters. Pity you ignored the cost of the hardware
required to write the media entirely. Utterly bogus.
Pity these 'numbers' are only a little
less bogus than the previous obscenity.
(Just once more, because I'm really tired of arguing with you,
Yeah, can get tiring having your utterly bogus 'numbers' exposed.
and I think everybody else will have got the point by now.)
Even you should be able to bullshit your way out of
your predicament better than this pathetic effort, Sachs.
Consider a user who needs to back up 10 GB of
data, which changes at the rate of 20% a month.
Thats very rarely seen with the personal desktop systems
being discussed. And with the few that do see anything like
that, it would be with those who produce personal video
footage and that stuff is better handled by writing the new
footage to more than one DVD than using tape for backup.
You have always been, and always will be,
completely and utterly irrelevant when we were
discussing the backup of personal desktop systems.
He wants to make a monthly full backup and
a daily differential backup (as I do) and keep
three months of history (1/4 of what I do).
Hardly anyone wants to do anything
like that with personal desktop systems.
What makes a hell of a lot more sense WITH PERSONAL
DESKTOP SYSTEMS is to write the stuff that you'll slash
your wrists if you lose to CDRs or DVDs if its video footage,
and use an external hard drive for complete backups of the
main hard drive for minimum hassle if the main hard drive dies.
You may choose to have the external hard drive big enough
so that it can contain more than one image of the internal
drive so you can gracefully handle the situation where the
system went pear shaped for whatever reason like a virus
but it took you a while to notice that that had happened etc.
And you dont need and endless series of history with that
full backup because if the worst comes to the worst, you
can always just do a clean reinstall and the fact that that
should be an extremely rare event indeed, since you do
have more than one image on the external hard drive, thats
no more than a damned nuisance if say the house burns
down and takes the external drive as well as the PC.
His setup cost for DDS3 tape is roughly:
DDS3 tape drive (we'll assume he doesn't
buy one of the steeply discounted system
pulls available on eBay, as I did): $600
Utterly bogus. You cant compare the price of high
risk pulls with brand new full warranty burners.
And even that utterly bogus price would pay for a very large
external hard drive, and a DVD burner and a CDR burner.
And if you use the real price of a brand new full
warranty DDS3 tape drive, you would have heaps
of cash left over if you avoid the tape drive route.
10 tapes (he only needs three, but let's be generous): $30
SCSI card (we'll assume he doesn't have one): $30
Total: $660.
Totally bogus price. You aint comparing apples
with apples when that price is a high risk pull and
the others are brand new full warranty hardware.
For CD/RW's, first off, he finds that his differential
backups require two disks after about a week.
Only a fool would backup like that. We happened
to be discussing the use of AN EXTERNAL HARD
DRIVE for that full backup. The CD/RWs are only
used for the stuff you'll slash your wrist if you lose.
So he goes to weekly full backups. He
needs 31 disks for each full backup, and needs 12 sets to cover 3
months, plus an additional 72 disks to do 6 differential backups a
week, a total of 444 disks. Let's cut it close and say 450. He pays:
Typical CD/RW burner: $80
Utterly bogus. No one pays anything like that
for a brand new full warranty burner today.
450 CD/RWs at $0.86 each: $387
Utterly bogus. Anyone with a clue uses the CDRWs for
JUST the stuff you'll slash your wrists if you lose and uses
an external hard drive for the complete system backup
to all convenient recovery if the main hard drive dies.
AND that external drive costs a LOT LESS than your DDS3 tape drive.
So yes, the CD solution is cheaper, by about 40%. Will that compensate
our user for having to swap 31 disks to back up his system every week?
More utterly bogus silly stuff when the external hard drive avoids that.
Or for the risk of finding that one of those 31 disks is
damaged or misplaced if he ever has to do a full restore?
More utterly bogus silly stuff when the external hard drive avoids that.
You obviously aint capable of rational thought.
More to the point, no one will practice a weekly
procedure which requires swapping 31 disks.
Duh. The external hard drive avoids that.
I've found that any backup system which requires manual media
changing is unworkable; most users simply will simply blow it off.
Duh. The external hard drive avoids that.
I haven't done the numbers for DVD/RWs.
I think they'll come out about the same.
And just as utterly bogus.
The device cost will be intermediate between CD and tape;
so will the cost of media and the number of disks required.
Pity you didnt even 'do the numbers' with the config being
discussed, an external hard drive to all fast and completely
automatic full backups of the main hard drive, without the
maintenance hassles that are inevitable with any tape drive,
and at a MUCH lower price than the hard drive, even if you
still use the utterly bogus high risk pull tape drives.
With the dirt cheap burner used for backup to removable
media of the stuff you'll slash your wrist if you lose, with
proper offsite backups of that crucial stuff, so that even
if the entire house burns down, its no more than a pain to
restore to the new PC that comes with the new house etc.
So, once more, in case the point has been lost in all of this fuss:
Wrong. As always. The point has always been that tape has
passed its useby date for backup OF PERSONAL DESKTOP
SYSTEMS. It now only has a place for the backup of servers etc.
the cost of backups on CDs, DVDs, and tape are very
different in some situations, not very different in others.
Waffle.
Which medium is appropriate depends largely on the user's needs.
Yep, and tape is almost never appropriate for
PERSONAL DESKTOP SYSTEMS ANYMORE.
External hard drives are MUCH BETTER VALUE, much more reliable,
much faster, etc etc etc. And a cd burner should be used AS WELL
for the stuff you'll slash your wrists if you lose, with proper offsite
storage of one copy of that stuff, in case the house burns down etc.
With a DVD burner being used instead if the volume
is high enough with say personal video footage etc.
For users who need to back up anything more a small
fraction of a modern hard disk, tape is the only viable solution.
Complete and utter pack of lies. As always from you.
