RE:[Veritas-bu] Netbackup PureDisk vs datadomain / Diligent..

[Koping Wang]

Hi,
We are also looking in D2D solution which work with netbackup. We are
going to make decision between DataDomain and Dilligent. This is my
thought about these two products.
Dillignet:
Pro:  VTL - low impact on configuration.
faster - it use fiber channel.
more add on functions - there are some good add-on functions you
can buy from diligent. 
Con:  costly - Software: Netbackup VTL license, Diligent license, Redhat
RHEL 64-bit license.
   Hardware: 64 bit AMD server, disk storage. If you
don't have san, you might need a fiber switch.
Datadomain:
Pro:Simple, no software license needed.
Con:  Not expendable, if you run out of space, you screw up.

Netbackup PureDisk: PureDisk is like a separate software from Netbackup.
You can have a lot of choice if you want to look into different D2D
products. PureDisk only support windows client.

Title: Message



I've 
been using Sepaton (www.sepaton.com) 
for almost 3 years now (Since Sept. 2003) - Two Words - LOVE 
IT.
 
Hardware is awesome - Service is great - Sales are 
not pushy.
 
I have 
a 45 Tb (RAW) unit (formatted down to 30TB - I am paranoid when it 
comes to Redundancy) - getting another 39TB(RAW) - next 
week.
 
They 
have a multitude of options - software compression (hardware is due out Q3), 
certified on both Decrue and NeoScale for Encryption, changed-blocks (Sepaton's 
DeltaStor) backups are in Q4.
 
But 
the most important thing - is that the only thing I had to so far as far service 
goes - replace failed disks (once every 3-4 months)

Ok..
 
How fare have you 
come in you evaluation with diligent and falconstor? Have you found any big 
difference between the two?
We have looked at 
diligent for some time now, the down side right now is that there is only 
one test installation here in Sweden which results little knowledge and no 
local support/service organisation.
Falconstor I think 
have a couple of installation and some more OEM installations. But I haven’t 
looked that much at them 
yet.

are 
you referring to Diligent's ProtecTIER, content based screening, that only backs 
up the changed blocks, minimizing the amount of data on 
disk??
 
Falconstor, IIRC, does software based compression before writing to the 
virtual tape, and that's it.

[Ashby, Andrew]

We have DD200's here and they have been true to our 
expectations.    We push all of our non-critical, short 
expiration, jobs to them.
We have been happy with the compression and reliability - 
though we have had a few issues.   Nothing we couldn't get 
fixed.
If its not already out there - their newest model allows 
you to connect to your own back end storage.
 
Would we buy again?  
Yes.
 
Andrew

My 
intent is to backup to VTL at night, and duplicate to tape during the day, 
every day.
we'll 
keep at least 2 weekly FULLs plus subsequent incrementals on 
disk
 
we're using the disk primarily as a means of getting 
away from multiplexing, as we have so many slow clients, that even with 8+ 
multiplexing, we can't stream our LTO3 driveswith VTL, we have don't have to 
deal with the performance hit of shoeshining, and we will get much better performance from SATA 
array to LTO3 during our duplication, than from network clients direct to 
Tape.
 
Also, because of pools and policies we're required to 
have, we can just create more virtual drives than we have physical drives, and 
the virtual drive doesn't care that there's only a single 10Mb/s client on the 
end of an encrypted link, whereas with physical tape, you're shoeshining from 
here to tomorrow, and tying up a $20,000 tape drive for 24 hours to backup one 
machine.later on, after that backup is done, it types up a physical drive 
for 5 minutes to duplicate.
 
that's my rational 
anyway.
 
Paul

  Do you have any 
  thoughts on how you would use tapes in a diligent or falconstor environment? 
  Or are you looking at only use disk as a backup media?
  For safety reasons 
  one could mirror the disk and replicate the servers to different sites, but 
  yet I don’t know if its enough.
   
  Basically with these 
  products you only have one generation of a fullbackup (if you don’t make some 
  more of curse, but then you need more disk capacity), which means if you lose 
  that disk all backups are gone. Do you see any risks with this? Of course if 
  you mirror the disk to one or more sites you are much safer.
   
  I think the tape 
  vendors have brainwashed me!! J

we're 
looking at Diligent and Falconstor.
 
primarily because Netbackup isn't "there" yet..DSSU doesn't cover what we 
need, and it doesn't look like they're ready to go wide open with purdisk yet, 
so with falconstor or diligent, we can license the SW and run it on commodity 2U 
servers and attach it to whatever disk we want, and roll it into our current 
environment with little impact..then when Netbackup is ready to play ball in 
the Enterprise D2D arena, we can re-allocate the servers, and re-use the 
disk directly, rather than having a big piece of proprietary hardware 
sitting on the data center floor.
