File/NAS direct to Veeam Data Cloud Vault

[KarmaKuma]

If I am not mistaken, unstructured/filer backups can be directly written to Veeam Data Cloud Vault, correct?

The only technical requirement is a cache repo, situated as close to the source data/NAS and proxy as possible (optimally all in a single, local subnet), sufficiently sized (~5% of source data size) and built on ssd as recommended in other posts/docs?

Our use-case and idea: Primary NetApp C30 with SnapMirror to secondary NetApp C30 in off-site datacenter, incl. local and remote tamperproof short-/mid- and longterm snapshots. "Straight to cloud" (Veeam Data Cloud Vault) backup offshoring for risk-mitigation w.r.t. bad-actor/ransom/etc. Immutable GFS based backup-set with history of 90 to 180 days (short-/midterm retention only, no longterm backup archive).

In our case, "straight to cloud" backup without first backing up to a local/on-prem repository is enough from a security/risk perspective if our risk assessment is correct. So, if there is no real technical requirement or big advantage of using a local/on-prem repo with offload/copy to cloud, we would like to backup directly to cloud.

Thanks for your inputs

Hi Karma,

Yes, that's correct. VDC Vault is listed as a supported repository (Object Storage).

The only technical requirement is a cache repo, situated as close to the source data/NAS and proxy as possible (optimally all in a single, local subnet), sufficiently sized (~5% of source data size) and built on ssd as recommended in other posts/docs?

Correct. We have documented this in our Best Practice Guide.

For a estimation of the cache repository and proxy resources, please take a look at our calculator:

Thanks a lot for confirming!

Do you have any sizing/metrics as to from what data-set on (size/filecount/etc.) hdd based cache should really be avoided and ssd seriusly be considered?

In our case we're talking about ca. 25TB/12m files on Netapp with a daily change rate of <=1%. Estimated growth is 7-10% and the cache repo should be sized for 5y, so ~ 40TB/20m files. The calculator suggests ca. 200GB cache and gives an estimate on S3 PUTs but does not state anything about the load on the cache repo.

We will put in place a SOBR based on 2x Dell R760xd2 with 24-28 hdd raid60 each for use as VMware primary repo. Could this be used for NAS cache without serious performance impact compared to ssd? Especially when planning to only run a single incremental NAS backup per day and not multiple incrementals daily? Trying to save some $$$ here and there
