Subject: [os2genau] Re Tape Backup

W have a TRAVAN SCSI back up solution  (Back Again 2000) and the tape drive is 
now cactus! Its over 6 years old and the mechanism is dodgy!

My question is are the current IDE tape drives now just as reliable and efficient?  In 
1995 when we set things up SCSI was the better choice but it seems that with better 
and better drivers etc, that the IDE Tape is quite fast (we back up at night anyway 
when all is at a standstill!)

As always, it depends.

Since you compared SCSI and IDE drives back then,
SCSI hardware has also gotten better.

( its probably still easier to connect an external SCSI
  device,
  than it is to add another internal IDE device )


Major improvements have probably been in

- motherboard data bus ( width in bits, speed - Hz,
                                       and chips to manage the bus )

- adapter hardware ( SCSI and IDE chips and adapters )

- improvements in SCSI and IDE 'protocols' with increases
  in speed and buswidth

- physical system memory ( for most of us )
 =

- operating systems like OS2
  ( which use the system CPU and memory to transfer data
    via data and device busses to your physical devices )


Now you have IDE with Ultra DMA
BUT you also have SCSI adapters which will support mind
boggling data transfer speeds, and a huge number of devices.


At least, whether you use a SCSI or IDe device,
you should be able to get the job done.

Chris

For tape backup, stick with SCSI. IDE or Floppy controller attached tape drives
are, in my experience "flakey" at best. Irrespective of which Operating System
is in use. They're simply not worth the aggrovation!

Now you could consider other media than Tape. Especially if speed is a factor.
Castlewood has you released a 5.2 GB version of their removable disk storage
solution. DVD-RAM and DVD-R are also options. If you use any of these
options you won't need the Back again software as you can address these as
a normal drive and a simple scheduled Xcopy or Zip will do the job.

Since you bought Warp Server for e-Business, I'd recommend you look at
the Warp Server backup program that is supplied with it. It hasn't been
publicised but it is a very good full backup solution supporting most
SCSI tape drives as well as local and LAN harddisks, optical drives,
floppies (Hmm, I wonder how effective THAT is ?) and ADSM
connections to midrange and mainframe systems. I use it here with my
Sony DDS Drive (SCSI of course).

Cheers/2
