[I exchanged a few out-of-band emails with
John about this, and anticipate that he'll post when he's done with his testing,
but he suspects a different part of his environment than the 6.5.3.1 update at
this point.]
For what it's worth, not that I tested every corner case, but I just
backed up 17 RHEL clients through my
test environment at 6.5.3, saw ~ 40 MB/s aggregate throughput (to a disk STU),
dropped 6.5.3.1 on the master, and reran the test with the same results. (I'm not pushing the client update just now
because those are actually clients from a
production environment.)
So if others were, as I
was, alarmed by John's report and back-pedaled on updating, you're probably
safe to (do your own testing! and then) go ahead and
upgrade.

Wow.
Can you get some solid metrics on the speed drop?
Is it only Exchange clients that are affected?
Are these clients, SAN clients, SAN media servers,
etc?
Have you opened a case with Symantec over the issue
yet?
(Yes: I'd recommend updating the client software. As I believe I
mentioned on list, the security vulnerability, part of what 6.5.3.1 corrects,
affects all members of your NetBackup system, including
clients.)

We
upgraded out master and two media servers to 6.5.3.1 (in order to backup a
standby Exchange CCR node and Windows 2008) this week and our full backups this
weekend are running incredibly slow, about 1/3 the normal speed. The
client agents have not been upgraded, they are at v. 6.5.1. Do you think
upgrading the agent will fix the speed issue, or am I going to need to open a
support case?
Thoughts?
Thanks.

3 times. 6.5 base, 6.5.3 patch kit, then 6.5.3.1
security patch. Without LiveUpdate, I can't see any way to shrink this to
less than 3 separate installs.
