DellEMC Data Domain as repository

[rasmusan]

Hello

We would like to use out DellEMC Data Domain as repository for Office 365 backups, however DDBoost is not natively supported i Backup for O365... and it is stated that SMB 3.0 repository i supported experimentally....

However Data Domain only supports SMB 2.1, even in newest releases and according to support they do not plan to introduce SMB 3.0

anyone had success with using Data Domain as repository in Backup for O365?? Maybe just using SMB 2.1?

thanks...

hey Rasmus,

that won't work I'm afraid. Also, the repository that we use differs from the one Veeam Backup & Replication is using. They are using "flat files" while VBO uses a JET DB as repository engine. Running this on a Data Domain would really be very bad for performance I'm afraid

Cheers
Mike

Hi Mike


hmn good point about JET DB - I will look into other alternatives !

thanks

Any update to this?

[nielsengelen]

No, dedup devices are not supported due to the fact that JetDB doesn’t perform on those.

ok, so I got a NFS mount on the data domain attached to my vmware environment. ill add a local disk using that NFS mounted datastore. does anyone know if you can disable compression/dedupe on a particular mtree on a data domain? im going to test as is to see how the space gets consumed on the DD and will report back once confirmed.

No, you cannot disable compression/dedup on a particular MTree.

Curious if you did try writing to Data Domain for your M365 backups. I suspect the SMB 3.0 requirement has more to do with concurrency functionality than it does performance. (https://docs.microsoft.com/en-us/window ... b-overview) In that case Data Domain will not work for you, although I'd think you could make a secondary copy of the backup and store that on Data Domain for that extra copy.
