If you want to have your content stored in IPFS indefinitely, you have to pin it on some IPFS node otherwise it will get deleted after capacity of IPFS node holding it currently is reached. This is similar to seeding a torrent. There has to be somebody who has complete copy of file before other peers can copy and redistribute it.
If you do not have own IPFS node there are services which will do pin it and have it available for other IPFS nodes for you. Good pinning service should allow you to specify duration of pinned files, do manual unpin in case you do not need these files anymore and extend pin duration. It is also helpful to have it replicated on more nodes.
