snapdiff roadmap

FelixZhou · ‎2024-07-03

we are currently using Rubrik CDM and snapdiff for NAS backups. according to NetApp, the snapdiff will not be supported after version 8.17. Rubrik is pushing us to a different backup solution of NAS cloud direct for NAS backups, but this is a duplicated investment and a lot of data movement.

does anyone have more details about NetApp snapdiff support?

looks if we lost snapdiff, the NAS backup on Rubrik CDM will still work, but on some shares which have multi millions files, the indexing and metascan will take hours to complete, it is causing user access issue to the shares.

Please share the information or workaround if you have.

thanks in advance

SnapDiff will continue to be supported by NetApp, but the current version of SnapDiff uses a different API architecture than earlier versions. This will require backup vendors that use earlier versions of SnapDiff to update their software so it can use the current version of SnapDiff. You can check with Rubrik to see what their plans are for doing this, and the potential timeline for it to be available.

@FelixZhou SnapDiff is a sensitive topic to both NetApp and their technology partners, here are some links for some more information:

Many customers had backups failing when they upgrade to ONTAP 9.10.1 with different backup products (Commvault being one) so there was a backpedal to reenable SnapDiff v1 and v2 for a few major ONTAP releases.

I would stay on ONTAP 9.13.1 if SnapDiff is a requirement and question your NetApp contacts for more information. The SnapDiff changes have created a divide between NetApp and their backup technology vendors so you need to get both sides of the story and form your own conclusion.
