default snapshot name case in SCS vs ONTAP

JS75 — Wed, 02 Apr 2025 10:50:58 GMT

Hello

Does anyone know the reason for default snapshot names in SnapCenter begin uppercase like 'Daily', 'Weekly', while ONTAP defaults to all lower 'daily', 'weekly' etc. Since snapshot names are case sensitive it's causing confusion and complexity with protection policies.

thanks,

Jacek

Hi Jacek,

Snapshots created by Snapcenter will start with the Resource group name. For example, in the output provided below, the snapshot names under the volume 'nfs1' beginning with 'RG1' were created by Snapcenter, whereas the rest were created by ONTAP.

To customize your snapshot names, For more detailed information, please refer to the following documents:

- [Create resource groups for VMs and datastores on Snapcenter plugin for VMware vSphere(SCV)](https://docs.netapp.com/us-en/sc-plugin-vmware-vsphere/scpivs44_create_resource_groups_for_vms_and_datastores.html)

- [Create resource groups and attach policies on SnapCenter](https://docs.netapp.com/us-en/snapcenter/protect-mysql/create-resource-groups-and-attach-policies.html)

Here is the output for your reference:

If my understanding is not correct, could you please share the sample output with me? I'll be more than happy to check and get back to you.

Hello Pravin,

I made a mistake - what I meant was the SnapMirror Label case mismatch. The default SnapMirror labels for ONTAP created snapshots are 'daily' and 'weekly' while the same for SCS and SCV are 'Daily' and 'Weekly'.

Hi Jacek,

Thank you for the clarification.

Snapshot label is case sensitive, you shall edit the resource group on Snapcenter /SCV and update the custom snapshot label matching your ONTAP snapshot label.

Refer below documents:

SCV: https://docs.netapp.com/us-en/sc-plugin-vmware-vsphere/scpivs44_create_backup_policies_for_vms_and_datastores.html

Snapcenter: https://docs.netapp.com/us-en/snapcenter/protect-mysql/create-backup-policies-for-mysql.html

Thanks and Regards,

Sure, I can do that. My concern was on why it's created this way that one NetApp product (ONTAP) uses lowercase while the other (SCS/SCV) use first-upper. It's quite confusing and I either have to create separate snapmirror policies for 'daily' and 'Daily' or combine two labels in one policy. Is there any specific reason NetApp did that this way?

Thanks

Jacek
