Hello Julia,

Two suggestions for you depending on whether you want to go with Firewire or SCSI.

* For a Firewiire solution, take a look at the new VXA-1 Firewire drive. The only drawback is that you'll still have to switch tapes manually.

* For a higher capacity automated SCSI solution which will leave you a lot of room for growth, check out the VXA autoPAK, which is a 15-slot autoloader/library available with either one or two drives. It gives you 495 GB of uncompressed capacity. It's one of the best values you'll find for an autoloader or library in this range.

Both of these are compatible with Retrospect. You'll find more details at www.vxa.com

Subject: Purchasing a new system
From: "Julia Frizzell" <[EMAIL PROTECTED]>
Date: Tue, 23 Jan 2001 10:24:25 -0500

Hello folks!

We recently got our funding for another 5 years from the federal
government, and including in our first year budgeting is the money
for a new backup system. I'm not planning on leaving Retrospect
behind, so all I really need help with is a new tape drive system.

Currently, we are using one DDS-3 tape drive for our entire local
base of about 70 users. About 65 of those are Mac users, and about 5
are Windows NT boxen. We also have 7 Mac machines that are various
servers, and 3 NT servers. For the users, we only back up their
bookmarks.html file and their Documents folder (using ASR we can
restore a desktop in little time, so there's no real need to backup
the entire hard drive), and *currently* we only back up the My
Documents folder for the NT user boxen, and specific directories for
our servers.

The desktops are backed up to tape nightly, with the laptops being
backed up to tape during the day by a backup server. The servers are
backed up weekly to hard drive (only exception being our Staff volume
getting backed up nightly). The main reason for the latter is that we
don't have anyone to do a tape switch after the Friday backup, I
think (this system was in place before I got here).

We change the nightly tapes daily, with incrementals M-Th, and a
recycle backup on Friday. I alternate tapes weekly, with an A set and
a B set.

What I would like to do: The backup server system mentioned by Craig
last week sounds like it would work great for me. I want to back up
the servers nightly as well, which will increase the space each set
takes up.

I am also interested in doing a remote backup of our NYC office. They
have static IPs, and could possibly be added to our backup sets. They
have laptops and desktops, and I'm just not sure if I want to go that
route, but it's a possibility. But on the other hand, if we do get a
new tape drive, we could send them our old one and they could use
that to backup.

So, should I keep the same tape system (DDS-3) and get a new drive
(auto-loader), get an additional drive (poor man's auto-loader), or
go with something new? I have the archive of this list from last
year, when someone went through and priced the different drives...ah,
found it! [see below] DDS-3 was second to Ecrix (oh, it's pronounced
ah-kree! Just noticed that on their web page. I'll have to stop
calling it eh-cricks :).

Oh, Retrospect is running on a Mac vanilla G3. It *could* possibly be
run on a MP G4, with a SCSI card or maybe Firewire/USB if that was
the way to go.

Advice would be appreciated.

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 set.  In
reality I only use 6 tapes in the magazine to keep things more manageable so
I can get up to 480GB on a magazine set.  We also have lots of single DLT
drives around but I only use those for special tasks.  So far It's been
working out very well .....

Here's a link to the HP series of products for you >

Subject: Backup FTP server?
From: "Steve Rothman" <[EMAIL PROTECTED]>
Date: Tue, 23 Jan 2001 11:37:32 -0500

I've used Retro's backup - to - FTP functionality a little, but now I
want to go the other way around. The FTP server I want to back up is
at a remote location, but I have full FTP access to it, but not shell
access. There is only about 20MB of data on it but it is in a complex
directory hierarchy with tons of little files.

I've been using Anarchie (ooops Interarchy) to copy the whole shebang
to a Mac, and then use Retro to back up the Mac. The Retro part works
fine, but I have a lot of trouble getting Anarchie to properly copy
all the files to my Mac, it often seems to get hung up and time out.
I think the server is a bit spotty, sometimes very reliable and high
performance, other times not so great.

Anybody have a suggestion for a good reliable (and hopefully
scriptable) way to get an entire FTP directory hierarchy on my Mac so
that Retro can then back it up?

And wouldn't it be cool if Retro could back up an FTP site? -Steve

Subject: VXA vexations
From: "David Thornton" <[EMAIL PROTECTED]>
Date: Tue, 23 Jan 2001 11:04:41 -0600

I've got a VXA drive with the low-voltage differential SCSI
interface, and Retrospect is giving me 206 errors whenever I
try to back anything up to the drive.

When first received, the drive was attached to my desktop G3
(beige) for testing, and worked very well. Once I felt it
was ready for full use (and when I finally found the time)
the drive and the ATTO SCSI card were moved to another beige
G3 desktop that serves as our primary backup machine. Now I
can't get the thing to back up anything without giving the
dirty heads, bad media error. Same SCSI card, same cable,
same tapes (tried several), very similar computer, same OS,
same version of Retrospect; the only thing that seems to be
different is the location of the drive. The backup machine
is located in the server closet, along with lots of other
equipment. I've tried a few different locations within the
space that's available to me, but that has done nothing to
help.

The Retrospect knowledgebase says something about
interference from another device being the culprit in
something like this. Has anyone else seen stuff like this
from VXA drives, or is it just me, or perhaps something
gone south on the drive?

From: "Stephen Jones" <[EMAIL PROTECTED]>

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 same situation
as 4mm.  The current best DLT is the 8000 series.  It's 40GB uncompressed by
6MB/second.  The Gen I version of the upcoming SuperDLT will *NOT* be
backward compatible.  Are you prepared to purchase something that will not
work with the very next version of the hardware?

AIT, also made by Sony, gives you two choices (AIT-1 and AIT-2).  AIT-1
(35GB/3MB/second uncompressed) inside a library costs less than $4500 and
holds 525GB uncompressed.  AIT-2 is 50GB by 6MB/second (and is considerably
less than a DLT library - it's also self-cleaning, DLT is not).

AIT-2 is backward compatible (read and write) with AIT-1.  You could start
with AIT-1 and upgrade to AIT-2 in the future should you need more capacity
and speed -- and use the very same library chassis.

AIT-3 (100GB by 12MB/second) is due out later this year and is backward
compatible with AIT-1 and 2.  When AIT-4 hits the street two years form now
(a proposed 200GB by 24MB/second), it too will be backward compatible with
all previous AIT generations.

DLT, up to a couple years ago, was definitely king of the hill.  But in the
game of technology, no one stands paramount indefinitely.  AIT has
definitely become more popular -- with a roadmap to larger/faster drives
while remaining backward compatible.  I was surprised to hear the news that
DLT could not offer backward compatibility with their upcoming SuperDLT
drive.  We have many DLT customers who will not be able to upgrade.  In
fact, because of that, a lot of our DLT customers have moved to AIT.

Please feel free to contact me with any tech questions, I have been a
storage engineer for ten years and work with all formats daily.

All the best!

I had a VXA 1 LVD SCSI with many problems.  The SCSI chain would loose the
device and Windows 2000 would report many SCSI timeout errors.  This all was
finally resolved when Ecrix replaced the drive and they also sent me a metal
plate that resides on the cable.  This plate removes any interference.

The drive now works like it should have.  Very nice although it took way to
long to resolve.  It appears that VXA drive are much more sensitive to any
noise.

Hope this helps,

Situation.

Some computers would be locked up in the morning when folks came in. It
appeared to be sleeping but couldn't be awakened.

I normally set all desktops to turn off at 5:30am to allow time for the
backup but have them off over weekends and holidays. (This is in
multiple offices.)

I finally figured out that it was likely the retro client waiting for
shutdown. If the energy saver turns off the monitor, then does an
automatic shutdown, AND the retro client is set to wait you get STUCK.
(Well I guess you could move the mouse a little at a time trying to hit
one of the buttons.)

So I've been trying to remember to turn off the DEFAULT wait at shutdown
that you get when you install a client but is there a way out of this
when it does happen?

re: 206 errors on Mac
Ecrix have revised the drive firmware to V2848
11/11/00 in order to address some of these problems.
Timing problems may vary from one system to another,
even with the same cable/adapter/terminator/drive
due to differences in the system clock and bus speeds
and also due to system and network loading effects.

Take a look at the Ecrix site for more info and make sure
you're using current firmware:

size=3D"+1" color=3D"#000000"> V2848&nbsp;</font></div>
<div><font face=3D"Verdana" size=3D"+1"

problems.</div>
<div>Timing problems may vary from one system to another,</div>
<div>even with the same cable/adapter/terminator/drive</div>
<div>due to differences in the system clock and bus speeds</div>
<div>and also due to system and network loading effects.</div>
<div><br></div>
<div>Take a look at the Ecrix site for more info and make sure</div>
<div>you're using current firmware:</div>

<blockquote type=3D"cite" cite>I've got a VXA drive with the low-voltage
differential SCSI<br>
interface, and Retrospect is giving me 206 errors whenever I<br>
try to back anything up to the drive.<br>
<br>
When first received, the drive was attached to my desktop G3<br>
(beige) for testing, and worked very well. Once I felt it<br>
was ready for full use (and when I finally found the time)<br>
the drive and the ATTO SCSI card were moved to another beige<br>
G3 desktop that serves as our primary backup machine. Now I<br>
can't get the thing to back up anything without giving the<br>
dirty heads, bad media error. Same SCSI card, same cable,<br>
same tapes (tried several), very similar computer, same OS,<br>
same version of Retrospect; the only thing that seems to be<br>
different is the location of the drive. The backup machine<br>
is located in the server closet, along with lots of other<br>
equipment. I've tried a few different locations within the<br>
space that's available to me, but that has done nothing to<br>
help.<br>
<br>
The Retrospect knowledgebase says something about<br>
interference from another device being the culprit in<br>
something like this. Has anyone else seen stuff like this<br>
from VXA drives, or is it just me, or perhaps something<br>
gone south on the drive?<br>

>Oh, Retrospect is running on a Mac vanilla G3. It *could* possibly be run on a MP G4, with a SCSI card or maybe Firewire/USB if that was the way to go.

I'd replace the DDS3 drive immediately - they only last 2-3 years in my experience so you're probably on borrowed time already.

I'd do the remote office over TCP/IP, either to your new tape drive or to a holding disc then to tape.

Then I'd get an Exabyte M2 or a rackmount dual-drive Ecrix to back up to. That way, even with addituonal data to be backed up, you should be able to complete the backup overnight without changing tapes.

Regards

PS - I would strogly recommend not re-using the DDS drive anywhere. If you need another drive get another Exabyte or an Ecrix. Another Ecrix won't break the  bank, and then you have drive redundancy...
