Re: Recommended Backup Job Settings for EMC Data Domain

Post by rntguy » Jul 17, 2017 2:50 pm

thanks. so i'll leave backup job at extreme, copy job at automatic (which will keep it as extreme), decompress upon arrival on cloud dd, and backup job storage optimization at Local 16TB+ for best dedupe rates by DD.

am I missing something?

[MERGED] DataDomain settings

Post by mtso » Mar 27, 2018 8:17 am

Good morning,
we have primary local backups and secondary backups to a remote Datadomain. We have a 1 Gbit pipe between the local datacenter and the offsite datacenter.

What are the suggested settings for backup to the remote Datadomain?

Type
- Backup job, "configure secondary destination for this job", or backup copy job?

Advanced settings, storage tab
- inline data deduplication: enabled or disabled?
- compression level ?
- storage optimization ?

Thanks in advance.

Tom

- Backup job, "configure secondary destination for this job", or backup copy job?
The first option points to backup copy job wizard, so these are just two (exactly same) ways to configure backup copy job.

Advanced settings, storage tab
Check this thread for recommended settings.

Thanks.

Hi guys,

i think this fits in here: A customer has got 2 repositories. We are copy-jobbing from each repo to one DD 2500 by DDboost.
Everything looks fine and the data rates are about 400MB/s on 1Gbit links, which is astonishing.

anyway: the DDboost clients on the DD show only one entry for one repository (which is the management host).
I just wanted to make sure that both repositories are using DDboost to the DD. Mostly the copy jobs are running
simultaneously so it's hard to tell if both use DDboost. shouldn't there be two entries on the DD showing both
repositories? or is the client hostname there shown only an alias defined by the management host?

cheers
kai

Any chance the management host plays the gateway role for both?

The gateway is set to automatic for the DD.
So I guessed it chooses the "nearest" gateway for each repository it's pulling data from.
repo1 should use repo1 as gateway and repo2 should use repo2 as gateway. both are windows hosts and
both are available options to choose from at the gateway config.

hmmm ... did I hit something here? sounds as if automatic GW is not really automatic.
at least it doesn't choose the optimal path for the data?

If automatic gateway selection is enabled, then mount server specified for the repository should be used (and if the mount server is not accessible, Veeam B&R fails over to the backup server). You're saying DD Boost shows "only one entry for one repository (which is the management host)" - as I understand, the management host is the backup server, so looks like it is used for both repositories in your case.

Anyway, if repository is added as DD Boost and the job to this repository works fine, then it uses DD Boost, no doubts. ;)

Hi foggy,

just doing a backup copy from 2nd repo to DD. the data is definitely pushed to the first repo and then by DDboost to the DD.
Looks to me as if the veeam transport service is relaying this. but 100% the 2nd repository is not speaking DDboost to the DD directly.
So "automatic" is not choosing the best / optimal way to push data from multiple repos to a DD.

Hmm.. looks like both backup copy jobs are backing up to a single DD repository then. In this case, the same server (mount host specified in the target repository settings) should be selected as gateway. If you create two repositories on DataDomain and point jobs to them accordingly, each should select its own gateway.

foggy, we can do that, but what is the point of "automatic gateway" setting? This doesn't seem to work as intended.
I'd suggest reviewing this on the product side and enable real "automatic gateway" based on the shortest path from
a repo to a DD. isn't that obvious?

I see your point, but due to some implementation specifics of the backup copy job, gateway cannot be selected the same way it is selected for the regular backup jobs.

foggy, can you introduce this as a product improvement request? I think we agree on the value of this setting ...
