<pre wrap="">I'm not sure I understand your question... it takes 48 hours to backup
to disk!
Of course, we can't afford to stop Exchange to either backup or restore
data. Everything has to be done online...

<pre wrap="">Something is very wrong. We use Legato Networker on Solaris and it
backs up many TB during the night including at least six Exchange
servers each with larger databases than yours. Of course we spread the
full backups so most servers only gets a diff or inc backup but still
the full backups never takes more than a few hours.

<pre wrap="">We generally install either Legato or Veritas and backup many Exchange
servers/TBs overnight. Check to make sure that the servers are being
kicked off at different times...don't try and start everyone at
midnight! 250GB is nothing.

<pre wrap="">I agree with all of you. It should not take so much time... disks are
on a local raid5 box. I think the time is spent extracting people's
mailboxes from the db and copying them to disk... but still, it takes
way too long...
How do you restore a single mailbox or some emails? Do you have to
restore the hole db and then extract the relevant emails? If so, it is
a waste of time and resources... unless there isn't any other way... I
think this is what they are trying to avoid but obviously it is not
working very well...
Thanks!

<pre wrap="">I'm not the Echange admin (thank god!), but IIRC what he does is that
he effectively "doubles" the size of the backup by exporting all the
mailboxes first.... And the echange module is supposed to facilitate
this too, but ... this was easier:-):-).
Our Exchange database seem to be the same saze (or slightly larger) as
yours... Shouldn't be taing 48 hours:-).
If you like, I can have a chat with him come monday, to get the gory details.
Cheers

<pre wrap="">Hi Glenn,
Yes, please tell me more about your setup.
</pre>
</blockquote>
<pre wrap=""><!---->Ahm, as I said.... I'm not the "exchange guy":-). Just had a chat with
him... Seems we only did the stupid export thing for a very short
while before transitioning to Exchange 2k3.
His emphatic advice is to only do an Information Store backup, and use
a method (described "in some docs by M$", his words, not mine:-) where
you work with a secondary (offline) database to do individual mailbox
restore. Since we work with disk backup, this is lightning-fast. The
secondary DB isn't large, and you purportedly don't restore the entire
thing... And he further asserts that this didn't work with exchange
prior to 2k3. And that's the sum of that:-). I imagine this is pretty
much what everyone else have been telling you;-)
(Sometimes that guy can be ... less than communicative:-/. Sorry for
the poor detail.)
Cheers

Yes, he's right. Especially when using ntbackup as it doesn't provide
individual mailbox backup.<br>
<br>
With Exchange agent that backup software provided, individual mailbox
could be backup. This is normally the setup of them.<br>
<br>
To backup individual mailbox, care should be taken on the mailboxes. I
faced on some mailboxes that have corrupted emails inside. These
generated a lot of errors or warnings and timeout (BackupExec) . So
the backup logs should be read to see what is happening.<br>
