DLT has not addressed that issue. Since linear pulls the tape across the
heads at a faster rate (150 inches per second vs helical scan's .5"/second),
it requires streaming -- otherwise you end up "shoe-shining". This
reposition is very intense on the heads/tape of a linear drive.

Not really. AIT and DAT and I assume M2 spin the heads and slow down the
tape but the relative speeds are in the same neighborhood. (I assume
it's easier to spin the heads faster than move the tape faster which is
why DLT appears to be falling behind in the race.) Anyway, you still

Yet another thought about backups.
Currently we have a dedicated NT server with 280 GB of cheap IDE drives
inside. Multiple times, in a day, it duplicates the changes from critical
servers (two remotely). The changes are usually no more than 300 MB per
execution.
The duplication serves several

I'm not planning on taking the discussion offlist, though I've had a
few responses offlist, and those have recommended Ecrix or AIT, so
those are the leading contenders.
My boss is really leery of Ecrix, no matter how much I push it. She's
worried that, should something happen to the company
I can't speak for everyone but I hope you keep this discussion on the list. If
it does happen to go off-line, I would greatly appreciate a copy of the final
thoughts.
I agree. IMHO the biggest problem with tape drives is not the purchase cost or the
tape costs, but the sheer level of grief
I've noticed that Ecrix is coming out with
larger tape libraries, Does anyone think that will make it a more viable
solution or is AIT still the way to go?
Hi Tim,
Ecrix has tape libraries (they call them autopacks) already in service.
And VXA-2 is right around the corner. AIT is a great
...in that case, go with Sony's AIT-2. The company is certainly in no danger
and they also have a road map to higher capacity and performance.
Both VXA and AIT use evaporated metal media rather than particulate
media making head life and drive reliability a plus.
Avoid cold/condensing
My boss is really leery of Ecrix, no matter how much I push it. She's
worried that, should something happen to the company in two years or
so (since they're the only one doing this kind of tape/drive now), we
won't have the $$ in our budget to purchase a whole new system. I
keep working on

Julia,
I can't speak for the other tape formats but I have always used DLT as it
seems to be the "Industry Standard". I would recommend taking a look at the
HP series of Autoloaders. I use an HP SureStore 818 which holds up to (8)
40GB Tapes (80GB compressed) so I can store up to 640GB on a
I would have to say AIT. Sony pulled the plug on the proposed DDS-5 so I
wouldn't suggest that line at all (end of product life). Also, DAT drives
have 1/5th the head life expectancy (10,000 hours instead of AIT's 50,000
hours).
DLT would definitely be better than DAT but is faced with the

Currently, we are using one DDS-3 tape drive for our entire local base of about 70

I am also interested in doing a remote backup of our NYC office. They have static

So, should I keep the same tape system (DDS-3) and get a
