Hello there @ju.mahieu,
I've tried it on a lab and was not able to do it via CLI, however i was able to do it via API / GUI, to do it in a reoccurring way you will need two steps:
1. You need to create a new Snapshot management policy
via GUI
go to ADMIN > Import/Export > then right click on Snapshot Management, and select Create Configuration Snapshot Management Policy
or via API
Method:POST
url: https://{{Your_APIC_IP}}/api/node/mo/uni/fabric/snpmgr-{{YourSnapPolicyNAME}}.json
payload{"configSnapshotMgrP":{"attributes":{"dn":"uni/fabric/snpmgr-{{YourSnapPolicyNAME}}","name":"{{YourSnapPolicyNAME}}":"download","fileName":"{{NameOfYourFile.tar.gz}}","rn":"snpmgr-{{YourSnapPolicyNAME}}","status":"created"},"children":[{"configRsRemotePath":{"attributes":{"tnFileRemotePathName":"{{YourRemoteLocationsPreviously created}}","status":"created,modified"},"children":[]}}]}}
2. Every time you want a new snapshot this policy has to be triggered and it can be done again via GUI or via API (my suggestion is to trigger it via API as you can automate it).
via GUI
Inside of your Snapshot Management Policy, on the Policy tab, on the option "Start Now:" select "YES", then click submit on the bottom right side.
via API
Method:POST
url: https://{{Your_APIC_IP}}/api/node/mo/uni/fabric/snpmgr-{{YourSnapPolicyNAME}}.json
payload{"configSnapshotMgrP":{"attributes":{"dn":"uni/fabric/snpmgr-{{YourSnapPolicyNAME}},"adminSt":"triggered"},"children":[]}}
