[linux-lvm] Backup costs (was: LVM reimplementationre)

[Daniel Whicker]

Ben,
	I think you missed a very important aspect.  The actual investment of
the tape drives.  A SDLT or LTO drive is going to run from about $4000
on up.  According to datacomm warehouse, a HP 230 external LTO drives
runs $3700.  An SDLT drive runs $4300.  You can't compare just the media
costs with that of the drive.  Let's consider a 1TB of data.

SDLT:
$4300 + (10 tapes * $50) = $4800

LTO:
$3700 + (10 tapes * $130) = $5000

AIT2:
$2800 + (20 tapes * $90) = $4600

IDE:
10  Drives * 270 = $2700

DDS4:
$900 + (50 tapes * $24) = $2100
