BE Puredisk is a port from NBU to run on Windows, NBU Puredisk was wriiten against Unix/Linux as such comparisons of version numbers (and release dates) are potentially not that valid.

Let's face it, BackupExec will never have the same level of development like NetBackup has today. Same goes for NetBackup, where it'll never get some of the development BE has. There is lots of overlap, but also some differentiators.
One of fthose is that NBU is updated more often, has a newer dedupe engine binary build, and more dedupe streamers. Not to say that there is an artificial limit put in one product or another, but it has to make you wonder...(So frustrating at times actually)

About the CONF files in BE... I've known about them for a long time, since BE2010. However, it was Symantec's opinion that users shouldn't mess with it, and didn't support changing any of those values for the first year+. They still only support a couple of things actually, not all the options.
Me? I still change em. I too used to have customers with PD6.5, and it worked really really well. Almost as good as Avamar from EMC.

Intersting info - however it does nto change the fact the BE suport team is finding issues with PDDE that are then found to also affect NBU (PDDO guess) - which kind of means that whatever the revision number, fixing issues with Dedup is a two-way street with NBU issues being used to fix BE and BE issues being used to fix NBU.

Teiva- Good point. You should NOT be messing around with these conf files if you don't know what you're doing. You'll mess it up bad. I don't see much reason to change any settings untill told so by Symantec.
Colin- I don't see where you're going with this... yes both BE and NBU will share issues because they use the same PDDO code.. BE just uses an older version, 6.5.
The question is why doesn't BE use PDDO 6.6 code? It's newer, faster, better... and what NBU uses.
BTW.. Now that I think about it... I don't think rebaseing was added to PD till 6.6.3... It wouled be great to see BE running on this code.
It's also funny BE reports its running 6.5.0.0.-Beta. LOL

Except there were some great settings to turn on like compression, changing segment size, throttling bandwidth, and encryption... yet for more than a year, the BE team were telling folks "it's not supported to change those settings." But it worked fine in the real-world.
The problem is really two different teams and testing schedules. What works good with NBU or PD or BE is not cross-tested with the others. This is one of the HUGE problems Symantec is facing today with their products and reliabiltiy. This is why there is so much layoffs happenings within the company. Trimming the fat. They needed to do this a long time ago!

\Here's another one that will blow some peoples minds... you can be running a much more up to date version of PDDO if you are running NetBackup 6.5 verses the most current version of Netbackup 7.5.x...
How's that? PDDO is built into NetBackup 7.x.. so you get what ever version that shippes with that verison of NBU. In version 6.x you had to install the PDDO engine on the media servers. So you can simply download what ever the latest version of PureDisk is, and then update your NBU media servers to match!
Oh.. here's an email reply when I asked if the long awaited BE 2012 version that will finally support VSphere 5.1 will also update the PDDO engine.. oh.. and if you read the email, they acknowledge BE runs an oudated PDDO version.. Colin?
Short answer: NO
Sorry for the delayed response. While there are plans to update our dedupe technology to the latest PureDisk version, the service packs for Backup Exec 2010 R3 and Backup Exec 2012 is only targeted to provide new platform support. Updating to latest PureDisk is definitely on our radar, but it is currently planned for a future release of Backup Exec.
How's does it make sense to have all these different version levels of your software duck taped and bolted to your different products is beyond me... but hey..

OK I did some asking around internally
Both the Built in/embedded NetBackup Dedup Engine MSDP (so not the separate Pure Disk Engine) are the same as the BE PDDE version and are 6.5 derivatives.
The full (none embedded) version PureDisk is the 6.6.x version.
The embedded versions of Puredisk do remain as a minor revision behind due to development timescales and other factors.
There is a future version of PureDisk being planned which on release will almost certainly affect the embedded versions in both NBU and BE - any changes will be as and when product updates for the core programs roll out PureDisk (Embedded) updates. As such BE may never go to the 6.6 codebase as it may just go straight to whatever version is most appropriate at the time and no I cannot give a timescale for such changes.
Also the word Beta in the command you mention for BE is a known issue (it was in fact me that reported it)

Colin, PureDisk is dead isn't it? EOL already. Some of my Customers were given FREE NBU 5200 appliances for their troubles of Puredisk 5000's and when on their own hardware. LOL.
So to say that BE/NBU will be behind is a bit misleading? Hopefully it'll surpass it. :)
