David,

I still use NBU 3.4 and bpvault extension 3.4 but I'm sure that NBU 4.5 
with the vault option works the same way.
Your DB backup will "sneak in" if it's queued and your vault job swaps 
tapes to duplicate another image, but it won't pause the vault job to 
allow a backup.
You ought to get a 3rd drive if your DB is at such risk.

Solaris server with STK silo with 2 9840<br>
&gt;tape drives.<br>
<br>
&gt; &nbsp;I have vault 4.5 running which takes up both my drives when vault 
is<br>
&gt;running. &nbsp;I have an important Database backup that must be performed 
to<br>
&gt;backup the arch files. &nbsp;If this backup doesn't get done the DB can't 
write<br>
&gt;its arch files and the DB will go down. &nbsp;This arch backup is started 
from<br>
&gt;the client whenever the arch directory hits a certain threshold so the 
time<br>
&gt;this backup starts in not set at a given time; it could be several times 
a<br>
&gt;day at any given hour. &nbsp;<br>
&gt; &nbsp; I only have 2 drives and when vault is running 1 drive is reading 
and the<br>
&gt;other drive is writing.<br>
&gt;<br>
&gt; &nbsp;Question<br>
&gt; &nbsp; &nbsp; &nbsp;With the set up described above, if my vault backup is 
running and<br>
&gt;will take a couple of hours, but I have this DB arch backup that 
suddenly<br>
&gt;wants to try to run, will it interrupt vault when its busy switching 
between<br>
&gt;&quot;read&quot; tapes? &nbsp;If no, how can I have an important backup run 
while vault is<br>
&gt;running and I only have 2 drives? &nbsp;Does vault use priorities like 
backups<br>
&gt;do? &nbsp;What can I do?<br>
&gt;<br>
&gt;Thank You<br>
&gt;David<br>
