Can I pin a specific CID from another provider to my own node


I am wondering if I can pin my file stored under a specific CID from also to my own ipfs node. I would like to make sure that my file is also available from my own node (and with the same CID).

Kind regards

CIDs are not tied to anyone, CID is purely computed from the content.
You can do ipfs pin add --progress=true Qmfoo (where Qmfoo is the CID you want to pin) and your node will pin it.
