Backup NetApp environment with cold data tier
Posted by sdrake_sul@reddit | sysadmin | View on Reddit | 6 comments
Evening everyone,
I’ve been tasked with researching backup and DR options for a our NetApp environment (a couple of Petabytes of mixed audio/video data, millions of files) and would love to hear what others are doing in production.
Our main challenge:
We need a disk-based daily backup solution that can leverage NetApp snapshots without causing cold data to move back to hot storage during backup operations. We have looked at Veeam and use it already internally. However to backup the NetApp it is very expensive. We would like to compare against other products.
Separately, we also have a requirement for a long-term tape-based archive (think multi-year retention), but that’s considered a different workflow — the primary goal right now is to find a day-to-day backup solution that works efficiently with tiered storage.
If you’re managing large NetApp volumes, I’d love to know:
- What backup product(s) you’re using (and why)
- How you handle cold vs. hot data tiering during backups
- Whether your solution integrates cleanly with NetApp snapshot technology
- Gotchas or lessons learned at this kind of scale
Thanks in advance for sharing your setups and experiences!

How is the data tiered in the NetApp system today? FabricPool? A scale-out cluster with volumes on either flash or HDD?

Thanks for the information. Currently it is tiered using a FabricPool

Install a secondary NetApp system, probably a C30 with 200 TiB usable or so. If you have 2 PiB currently, this is comfortably about 10%.
Atttach Fabric Pool to this C30, but not the same bucket as you use today. I'm not sure if the S3 storage is onprem with StorageGrid or cloud storage. Doesn't really matter, just make sure the S3 bucket is not the same region/zone or even the same provider.
Set up SnapMirror/SnapVault. The initial base line will need to read everything from the cold tier, but this is only needed once.
Subsequent snapshots will inherently only replicate hot data to the secondary system, and you're all set.
Another option is to use SnapMirror Cloud to an S3 bucket. A bit simpler, but this is the full volume only. There won't be any snapshots available on the Cloud copy. A restore will have to be full volume.

Was using Commvault to back up our NetApp + a dell tape library, recently migrated to cohesity which can do tape, but we decided against it. Replicating to another cohesity cluster in a different department of our org and also doing long term cloud backup with their Fort Knox offering. We do only have about 30 TB of data though

Been a while since I played with NetApp backups, assuming things haven't changed that much.

Thanks for the insights I will check these out.
