Re: [Veritas-bu] Question for NetBackup 7.0 Dedup user OR Data Domain users

Remember that the built in de-dup
as a limit on the amount of data it can keep track of.
Over that amount you need to use a
de-dup appliance.

Subject: [Veritas-bu] Question for NetBackup 7.0 Dedup user OR Data
Domain users
We are looking to change our
backups to a disk based deduplication solution, and 2 of our options are to
utilize NetBackup 7.0’s built in dedupe (Client and Media server) or to
put a Data Domain box in. I wanted to see if I could get some real world
feedback on what you guys have been seeing in terms of dedupe rates,
performance, etc. For example Data Domain claims we would only see about
5:1 dedupe rate using NetBackup, which seems quite a bit lower than what I
would expect….and of course they claim they would get about 20:1. I
realize that all data is different, which is why I have hopes that several
people will reply with what they are seeing. Thanks for your time!
