Re: Backing up a Butler SQL Server

2000-12-14 Thread Jim Coefield

Phil,

Butler SQL 2.5.2 (the version I'm using) is Apple-scriptable. The 
User manual contains a sample script for it (if you don't have access 
to the manual, let me know, and I'll send it to you). The User manual 
has a whole chapter dedicated to backup strategies (and the Reference 
Guide goes into greater detail) and also states the following:


Butler SQL includes support for online backups using its Backup command.

The Backup command is necessary because it is not possible to
make reliable copies of files that are in use. For example, you do not want
to backup a database that includes partially completed transactions.

Butler SQL's Backup command:

* waits until all current transactions are completed,
* makes a copy of the one or all of the databases installed on the server, and
* detaches the database journal and activity logs.

While the backup is in progress no users will be allowed to update the
affected databases or begin a database transaction. Users will, however,
be allowed to view data in the databases. Once the Backup command has
completed normal access to the server will be restored. At this point you
can then use your backup software to copy the files to archival media.
Refer to the SQL Reference Guide for a detailed description of the Backup
command.

The backup command can be issued from any application that allows you
to send SQL to a Butler server. For example, you could use AppleScript to
write an applet that connects to your server, issues the backup command,
then disconnects. Here is a simple AppleScript script that will backup a
database on a server...

Good luck,

Subject: Backing up a Butler SQL Server
From: "Phil Geller" [EMAIL PROTECTED]
Date: Wed, 13 Dec 2000 07:40:40 -0800

A client is using a Butler SQL Server to support a Panorama database.  This
database stores data in RAM.  I would like to Retrospect server, running on
the same system to shut it down, so that the data is flushed to a file,
before the backup starts.  Butler SQL is not Apple Scriptable (at least
without an optional add-on, which may not be available for this version... I
haven't researched that yet.)

Does anyone have thoughts on the best way to deal with this?  What I've done
for now is shutdown and restarted the server just before the backup begins.
If it works that should update the database file.

Re: Error 212, VXA, Retrospect 4.3

2000-11-03 Thread Jim Coefield

Dave,

I'd first follow the advice given me by Ecrix Irena a few weeks ago, 
and if that doesn't help, most likely your drive is experience some 
sort of scsi problems with your computer. I'll forward you that post.

If that advice doesn't help, I'd contact Ecrix and tell them about 
your situation. Pulling logfiles and giving them sense information 
from the drive will help to resolve the situation. Some of us with 
certain configurations have been working with Ecrix to resolve 
problems with Retro Mac and VXA drives. They are working on firmware 
updates to resolve specific problems that folks are experiencing. I 
have found Ecrix to be most responsive to folks with certain 
configurations who can help them debug their drives.

Subject: Error 212, VXA, Retrospect 4.3
From: "David Weeks, weeks.de" [EMAIL PROTECTED]
Date: Fri, 03 Nov 2000 00:53:51 +0100

Hello All,

two weeks ago we bought a VXA drive which we are running on an Adaptec SCSI
card in a PPC 8500/200 with128MB RAM.
Backups run just fine and very fast, but after having backed up the entire
network (probably 40GB) the next incremental backup suddenly stops and asks
for the tape that's already in the drive. This tape is now marked as
"gelöscht" which is German for erased or deleted. When this first happened I
ejected the tape and put it straight back in the machine and it appeared to
recognise it but when I tried to continue the incremental backup it brought up
an Error 212 message. When I tried to retrieve data from the tape it appeared
to rewind to the correct spot and start to retrieve the document, but then
stops and again brings the error 212 message.
The first time this happened I thought that I had maybe set up the script
incorrectly or had inadvertently deleted the tape. Therefore yesterday I
rewrote the backup scripts and backed up the whole network again onto a new
tape. This evening I came back into the office to find that todays incremental
backup had also stopped and was again demanding the tape already in the drive.
All other details are again as described above. This is, as you will surely
realise, a very disturbing situation for us as we are now without a safetynet
and our old DAT based system simply cannot cope with the amount of data we are
generating.
if anybody is able to shed some light on this Iwould be very grateful.

Best regards,

David Weeks

Re: retro-talk #741 - 10/25/00

2000-10-25 Thread Jim Coefield

Irena,

I've had good ideas and response from Ecrix, and we are working on 
the problem. I think that we'll work it out, one way or another. I 
have the utmost respect for Retrospect (dozens of my clients use it 
flawlessly (with many different backup mediums), and I believe that 
Ecrix is trying its best to bring new technology and products into 
the tape drive arena to provide good affordable solutions for small 
to mid-size business LANS.

I do think though, that with the VXA promotions, and the newness of 
the drives, that some of us are doing a bit of beta testing for them 
(and they have been very responsive in tech support). I hope that we 
can work all the bugs out, because after looking at many different 
technologies for backups, initial cost, media cost, techno 
improvements, etc. I still think that Ecrix has a hot product. It 
just needs to be tested out in a bunch of different environments, of 
which I'll admit that mine is a bit unique. And then tweaked for 
perfection.

Thanks,

Jim Coefield,

Hi Jim,

I put these notes in to remind folks that an error 206 with a VXA drive can
be caused by factors other than the issue reported on MacIntouch. Ruling out
these other factors in your situation pinpoints the problem, thus contacting
Ecrix makes sense. I just don't want users to be waiting for information

Could we get an update from Dantz and Ecrix on the VXA/Retro Mac
issue, as reported by MacIntouch, 10-20-00 (see below)?

The post on MacIntouch goes a long way to explaining some of the
problems I've been seeing with my VXA drive. If not for having just
finishing rebuilding my LAN and upgrading my net connection, and
installing new servers, routers and switches, I was going to dive
into troubleshooting the problems I've been having. Maybe all I have
to do is wait for the firmware update?

I've not only got many 206's, but errors 102 (trouble communicating),
203 (hardware failure), error 205 (lost access to storage medium),
error 100 (device rejected command). In addition, after these errors,
the drive will not continue to use the current tape, and always wants
a new one (whether 4 gigs or 40 gigs were written to it)--leading me
to believe the the end of write markers were never properly written,
which could leave the tape in an unusable condition.

Also, the drive can take up to several hours to eject a tape after
one of these errors--following Ecrix's advice to eject a tape: power
down the drive, disconnect it from the backup Mac server, turn it on
and hit the eject button many times quickly in a row. Makes for a
very tedious process of continually regenerating backup sets.

I've been using a BW G3/300 with a Miles Initio Blue Note scsi card
and OS 9.0.4 with Retro 4.3. Using the VXA tool to maximize capacity
over speed seemed to exacerbate the situation.

Re: computer synchronizing

2000-10-09 Thread Jim Coefield

Phillip,

I'm using Retro 4.3 on the BW G3 backup server running OS 9.0.4, 
which also is the destination for the duplication (to an HFS+ disk 
partition). The source is coming off of a PC running NT 4 Service 
Pack 3 on an NTFS formatted drive. It's always the same files that 
get reduplicated (or so it seems as they go streaming by in the 
duplicate window--no file by file logs on duplicates). I can find no 
rhyme nor reason why it's the same files. They all have the same 
directory permissions as the root directory that gets sourced by 
Retro.

Which platform are you running for Retrospect?

I have found that there are enough differences between file info on 
Windows and MacOS, that Retrospect would not match the same file 
located on the two different file systems.  This could be especially 
true if one volume is NTFS, since Retr.o for Mac doesn't recognize 
the NT security settings.

As a side not, I found this also to be true with Apple's folder 
synchronization tool with one folder being on a PC formatted disk 
and the other a Mac drive.

Any one else care to comment?

[OT] Re: clones and PowerPC computes

2000-09-29 Thread Jim Coefield

rant

OK,

It's not often that I get into these sorts of me too's, or platform 
put-downs, but as the proud owner of a Power Computing PowerBase 
Minitower, and 4 7200's (and many other machines), and having 
provided support for many Power Computing computers over the years, 
I've got to say something here.

The PowerBase, while based on the 7200 motherboard, made many 
significant improvements on the original design, including the 
ability to upgrade the machine easily with the addition of a daughter 
card processor, not to mention initial processor speeds of up to a 
240Mhz 603. PowerBases are easily and cheaply upgraded to G4's, and 
run rock solid--try that with a 7200 (without an expensive mother 
board swap).

The PowerBase also came with on board IDE, in addition scsi, making 
the addition of large/cheap IDE drives easy. Not to mention having an 
extra full size bay for, say, a CD-R; try that with a 7200--no can 
do. Pop in a good fast scsi drive for the system/apps, and then pop 
in a cheap IDE for storage, and you've one heck of a fine computer.

Yes, the fans were noisy, but a pair of Silencers at $12/each easily 
took care of that, and you also could easily add a processor fan for 
$10 to cool that 240Mhz 603 or G3 or G4 upgrade. The Mac 8500 is just 
as noisy, but thrice as hard to get into and work on. Oh, and lets 
not forget the built-in vga monitor port to hook up other than Apple 
monitors without an adaptor. All-in-all one heck of a fine machine 
for those who like to tinker! I'll be using mine in my home office 
for years to teach my kids about computers--using and 
repairing/upgrading them. Ever see an 8 year-old girl put a CD-Rom 
drive in a computer by herself? Not in a 7200 you won't, but in a 
PowerBase MiniTower she can.

And for the 7200's, I currently run three of them for servers--email, 
listserve, and web. Yes, they're getting old, and yes I'm getting 
ready to swap them out, but they've been faultless 
workhorses--running for 4-5 year's straight without a squeak. I'd 
rather invest my $$ in bandwidth first, then upgrade the machines.

There's many good reasons Apple bought Power Computing. They had 
great engineers, who were beating Apple to the market with products 
that had more punch and value than their Apple counterparts, and 
eating up market share. They had a team of marketing individuals who 
put together one of the first kick-$^% online stores and excellent 
marketing campaigns. The $100+ million Apple spent to buy them out 
was, in addition to eliminating competition that was threatening 
their success, to bring that expertise in house to Apple--those 
engineers and marketeers that wanted to work with Apple, that is.

Having said all that, I wouldn't hesitate to bring my upgraded 
PowerBase into my hosting LAN and use it for a backup server, a web 
server, or use it for any purpose whatsoever. In fact there are 
hundreds, if not thousands of them out there being used for just 
those purposes. One only has to go to http://www.powerwatch.com and 
login to their PowerPC users forum to see the vibrancy and life that 
still exists in the PowerPC platform.

  Actually, most of the motherboards are the same as the Apple 
equivalents.  They changed other things like floppy drives and 
CD-ROM drives to a cheaper 3rd party though.
  
  I had a customer that had a Power Computing PPC.  Equivalent to 
the 8500. I opened it up and the motherboard had an Apple part 
number on it.  The processor board was made by someone else.  The 
floppy drive had died within months of getting the system.  The 
CD-ROM drive makes an awful noise, but it still works.  The power 
supply is basically an ATX power supply that was modified a little.

I think that is exactly what the first contributor meant when he

34MB for a 2 tape VXA set archive (that I will be letting grow 
indefinitely), and 25MB for a new single tape VXA set (using

Stewart is correct. A file backup set's catalog is stored in the file's
resource fork, which cannot grow past 16 MB in size. This issue is covered
in the 4.3 Read Me and Retrospect Help.

Solving this problem requires *significant* changes to Retrospect's backup
set architecture--it's not a simple matter. We are working to address this
issue with a future release.

In the meantime, the Retrospect Help file suggests the following
workarounds:

o  Perform a recycle backup to the file backup set, which
clears the catalog and starts anew. (Backed-up data in
the set is removed.)

o  Perform a new media backup to the file backup set, which
creates a new, empty file with an empty catalog. (The
old file is left intact with its backed-up data.)

o  Do not try to copy so many files or volumes to the file
backup set. Consider creating separate backup sets for
different volumes.

o  Stop using file backup sets and instead use CDs, disks,
or tapes. You may transfer backed-up data in file backup
sets to other kinds of backup sets.

o  Leave the catalog compression option on (it is on by
default) to help keep down the size of catalogs.

I hope this helps.

Thanks Larry,

This sounds like a decent compromise between the extremes (no 
Protection, the Multiple User work arounds, and high security like 
DiskGuard or others). I don't think that most folks wandering around

probably are smart enough to defeat any security system--just open

This screensaver also sounds excellent for those Macs/monitors that

To prevent intruders from disturbing the backup server while it's logged in,
use the BlackWatch screen saver http://penumbra.apple.com/blackwatch.html
to password protect your computer.


BTW, there's a posting on the BlackWatch web site that says:

(8/23/00) A patch for Retrospect (versions 4.0 through 4.3) is now

performing a scheduled backup, making it fully compatible with BlackWatch.

Re: Duplicating volumes

2000-06-08 Thread Jim Coefield

Garrett,

I had the same dilemma, and came up with some reasonable solutions 
(if you have adequate drive space elsewhere on your network). Beauty 
of this, is you have two duplicates. I'm assuming that the servers 
you are referring to aren't your Retrospect server machine--that you 
are using Retro on one machine to do the backups on separate server 
machines.

Goes like this:

Solution 1)
Set up two duplicate scripts. The first one will mirror your main 
server drive to a second machine (a subvolume on that second 
machine's hard drive works fine). Set this script to go off first.

Then create a second script to duplicate the subvolume on the second 
machine to duplicate back to the second drive on the server. Make 
sure the time for the second script is set to go off after the first 
script.

Solution 2)
If you have two servers with two drives in each, you also could 
duplicate one server's main drive to the second drive on the second 
server, and vice versa for the second machine.

Solution 3)
Alternatively, you can put the second drives on another machine, and 
just run a duplicate script from your server to it's new location. 
Then when/if you need the drive, if your main server drive fails or 
crashes (or you have some other hardware failure), you can just 
re-hook it up to your main server and away you go, or use the second 
machine as a backup server while you rebuild your main server's 
drive, or replace it if it's failed. This also has the advantage of 
only hitting your main server once for a duplicate.

Be forwarned that file sharing privileges will not be maintained 
during duplicates, as the permissions are always relative to the root 
of a certain drive (in this case your main drive)--I don't believe 
that even naming the drives the same thing will maintain those 
privileges. I have replaced drives on computers, and named them the 
same thing as they originally were, and then restored the drive via 
Retrospect, and when I run a regular backup script to tape, I always 
have to go back and forget the old drive, and add the new one to the 
script. I believe that Retrospect looks deeper into the drives 
identity than just it's name and the computer it is on to recognize 
it on a network (is this right Dantz?).

So if you are using Apple's Users  Groups with file sharing for, say 
NetPresenz ftp to use with a web server, then you're out of luck, and 
will have to reset those permissions manually. Found out this the 
hard way. Now, if someone else has found a good way to maintain those 
file sharing privileges during duplicates, I'd love to know! :-).

And yes I know that running AppleTalk and file sharing on a server is 
not a good thing (if you have OS 9 you can use TCP/IP file sharing 
and turn AppleTalk off), but until I either upgrade to another ftp 
server that doesn't use file sharing, or upgrade WebStar to v4.x 
which has a decent ftp server built in, I'm stuck with NetPresenz to 
allow access to my servers. And I like NetPresenz--wish that 
Stairways Software would have continued developing it!

I'd be happy to just have new installers, that didn't require you to 
install one version (like 1.1 for Windows) and then update it (to 
v5), and allowed you to install the latest version in one step. I've 
used up all of my PC client numbers, but have quite a few Mac #'s 
left (that can be used with Windows v5 client). When you go to 
install the 1.1 Windows client, it won't accept the Mac numbers like 
v5 does, so you have to go through the stupid step of either 
deactivating another PC (and , or converting it to a Mac serial #, to 
"borrow" the number to activate the 1.1 client just so you can update 
it to v5. It's a big PITA. Maybe there's an easier way to do this,

Re: using large hard disk as backup destination

1999-12-21 Thread Jim Coefield

This is what we do in our GIS lab. We automatically duplicate 
(nightly when no ones working and files are closed) many drives that 
contain our critical ArcView and ArcInfo data scattered across our 
network (combination Windows 95, 98, NT4) to a single map server 
(NT4) via Retro on a Mac (100base-T ethernet) that has several 27 GB 
hard drives. You just need to make sure that the subvolumes you 
create on the destination drives, representing the drives scattered 
across the network, contain enough free space.

The map server w/backup drives then gets backed up periodically to 
tape. This situation seems to keep our map techs happy, as they worry 
about data integrity once the GIS info has been written to tape, 
given Arc's unique handling of data structures, pointers, and 
workspaces. Restores for Arc GIS data have to be done very carefully, 
and being able to move data from a duplicated drive back to its 
original location is much preferred to restoring from tape. Took one 
Arc workstation meltdown, wrestling with the Arc data structure to 
devise this (hopefully) foolproof system.

One gotcha on many PC machines: the BIOS can't handle drives larger 
than, I believe 32GB without being upgraded. Not all PCs will allow 
you to upgrade their BIOS, or it isn't worth the time and effort to 
do so. Found out the hard way, which is why my BW G3 has a nice 34GB 
Maxtor (which had a disclaimer "inside" the box about this possible 
limitation), and the PC has 27GB drives. Not often you can one-up the 
PC/NT support person, when you're the Mac guy in the lab. But in this 
situation with Retrospect, you sure can.

Hmmm - here's an alternate possibility:

1.  Set up a folder for each client volume to be backed up
2.  Set each folder as a volume using the subvolume option in Retrospect
3.  Create a duplicate script for each of these.  Using the duplicate
function with replace entire HD, you will get a mirror of each volume on
the server - retrospect is smart enough to do an incremental duplicate
so these should run pretty quickly
4.  Then backup the server locally to a handy tape device.

This will require more active management and tracking as you won't be able
to use Retrospect's advanced search features by client name since it will
all be one data source, but if you organize your server structure carefully,
you should be OK.  You also won't be able to use the smarts of the backup
server scripts and will be stuck with scheduled ones (not critical for a
smaller backup group tho').

NB - this only works if you have a clear controlled client group that you
know exactly the available capacity and can ensure that you have sufficient
space on the server.

Ancillary issues are that if you have a mix of Windows and Mac clients there
are some naming issues that may arise since the Mac can't handle names over
32 characters, and if you decide to try this from a Windows box, you'll need
to ensure that you have things set up to properly handle MacOS resource
forks. Sigh - nothing's ever as simple as it first looks.
