Exchange Logs deleted on backup
Joe 21.06.2007 19:28:02
I have just installed a Sonicwall CDP device that is set to backup Selected
folders including exchange.

Any exchange aware backup solution deletes the exchange log files. However
since I am now using 2 backup solutions, and the two don't communicate with
each other the Sonicwall device attemps to backup the logfiles on a periodic
basis but will generate an error if it can't find the correct numbered log
file.

Is there anyway to stop the SBS backup program (which uses NTbackup), to not
delete or tuncate the exchange log file after it runs?

No. I'd pick one backup solution and stick with it. You could disable
SBSBackup and use NTBackup to do an online backup of Exchange to file, and
then back up that file with your other device.

Heres the deal. This device CDP device doesn't do a full backup. It sits on
the network and monitors whatever yoy ask of it. for example with exchange,
it will take a snapshot every 4 hours. If you use it to backup the
mydocuments folder on the bosses computer the instant he finishes a document
and saves it, it copies it to its hard disk. At off hours it will move the
days changes off site to a storage farm. Its not designed to do a full server
backup per say. Thats why I want to keep the server backup going. Obviously I
can switch to a second party backup solution and turn off the log deletion
that way but thats more $$$. I was just hoping that there was a way to change
SBS ntbackup.

You'd probably have to Edit the BKPRUNNER.EXE with a HEX Editor.

Now I've Successfully edited it to remove the Verify,
but I haven't looked at the HEX Long enough to figure out what to touch for
that.
Grab a HEX Editor and test. You may find the part that says how to name it.
:)

Of course you are on your own :)

Maybe just move the transaction logs to a different directory from the
databases and not have the "CDP" device even look at backing up the
log directory?

Does this "device" even claim to be able to backup/restore Exchange mounted
databases?

First, I apologize fo waiting so long to respond back. I took a long weekend
to vacation a little then had to play catch up.

Russ, I will look at the hex editor part although the likelyhood of messing
up is probable rather grat.

kj, this device (it is a Sonicwall CDP) is very exchange and SQL aware. When
it does a full backup it delete the log files. If it does an incremental it
does not. It will do a full restore. It keeps track of the log file names and
is only likely to get into trouble if another device has deleted the log file
and now it does not "see" the correct name.

Since both of your exchange aware backup programs are 'uncoordinated, it
would seem only logical you are going to need to make a choice ( at least
for exchange full backups) and work around any shortcomings.
