Yes Rob is correct. In my mind I had typed hp/ux 10.20. 
 
And the problem with hp/ux 10.20 is not unique to netbackup. The TSM stopped 
active support for hp/ux 10.20 a little while ago. But one difference with TSM 
is that they officially support one client version up and one down. But 
unoffically the clients work many versions back. And with hp/ux 10.20 they even 
have semi-support of the older client level. 
In the case of TSM the problem was threading support, their newer clients 
required threading and hp/ux did not have the same threading support as others 
unix's. 
 
It would be nice if netbackup would support older clients. But maybe not at the 
same level of support. 
For example they might support nbu 3.4 for hp/ux 10.20 but not for hp/ux 11. No 
new features.
 
This is important for at least 4 reasons. 
 
1) sometimes a site is running apps (purchased) where there is no way they are 
going to be upgraded to run on the lastest os level. 
 
2) Sometimes a site is running hardware used for special purposes that is not 
going to be upgraded. For example an xray machine with an old pc or unix box 
for an controller. The xray company supports the hardware as is but does not do 
upgrades on the older boxes. To get an upgraded computer means buying a new 
xray machine, which is many times the $$ of the computer. 
 
3) DR purposes. One may be asked to restore data for backup taken many years 
ago. 
 
4) Major software systems work with the old o/s but not the newer levels. And 
management does not want to fix something that is not broken, with large $$$.

        I think Len's comment above was intended to refer to the 10.20 HP-UX
        release, not the entire HP-UX platform in general.  ;-)
        
        There are also a few solaris 2.5.1 users out there who aren't so
        happy about these supportability rules...
