Integration with deduplication appliances

[evilaedmin]

Hi,

Deduplication appliance (StoreOnce) can show global deduplication ratios for each repository (Catalyst Store or NAS store), and Veeam / VeeamOne can show me the logical size of individual backup files / VMs), but are there any ways to leverage existing tools to learn which VMs may not be good candidates for a deduplication repository: some example hypothesis would be that they are hosting too much pre-compressed media, or others.

Thanks!

Hi Eugene,
Could you elaborate on your environment and backup settings?
Do you use inline (Veeam backup job) deduplication and compression?
If you keep backups on deduplication repository it is recommended to turn it off.
Thanks

Hi Nikita,

For purpose of conversation, let's say I have 100% best practice StoreOnce settings for Veeam backup repository: Per-VM backup files, uncompress before writing, weekly Virtual Synthetic Full, licensed Catalyst integration. I'm hoping that VeeamOne if not this version, in future, can give me detailed information of StoreOnce Catalyst performance.

Indeed Veeam ONE doesn't have close integration with dedup storages yet. However if you have deduplication repository Veeam ONE will show full size of all backups separately from the used space (after deduplication), so you can see how much data is saved by the deduplication.
Is that sufficient to see how much data is saved you you would like to know which files were duplicated most/less?
Thanks!

Exactly this, with maybe reports to help with Trending for when situation changes, such as formerly well-deduping files suddenly less-compressible.

Got it.
And what is the use case, i.e. what is the plan if you find out some files are less-compressible than others?
Thanks!
