How to Keep IPFS Files Available Long-Term: Pinning, Backup, and Recovery

On-Chain

22 October 2026

IPFS itself does not guarantee that files stay available long-term. It is only a content-addressed network that tells you where to find files, but nobody is obligated to keep your files forever. To make an IPFS file accessible long-term, you must do two things: pin it in at least one reliable place, and ideally keep copies in several independent locations. If you rely only on a single free gateway or a single pinning service, your file will eventually disappear.

Pinning: Keeping Files from Being Cleaned Up

IPFS nodes run garbage collection regularly, deleting data that nobody is using to free up space. Pinning tells a node: do not delete the data for this CID. When you run ipfs add locally, the files you add are pinned recursively by default. But local pinning only works as long as your own node is online and your hard drive is healthy. If your laptop shuts down, the drive fails, or you manually unpin the file, it is gone.

For files that need long-term availability, remote pinning services are a more practical choice. The official IPFS documentation lists several scenarios for this: your local node is not always online, you need a backup, your local disk space is limited, or you want multiple nodes to keep copies. Third-party pinning services such as Pinata and Filebase essentially run IPFS nodes for you and charge money to keep your data. The official IPFS documentation reminds users: these are services operated by third-party companies, and there is no guarantee they will continue running forever. You should research them carefully before relying on them.

Pinning is not a permanent promise. If you stop paying, or the service provider shuts down, your data can still be lost. The IPFS documentation puts it bluntly: paying a pinning service simply outsources the job of covering storage costs. If the person paying stops paying, the content may disappear completely. IPFS guarantees that content can be found, but it does not guarantee that content remains available.

Backup: Redundancy Matters More Than Any Single Solution

The experience of Astar Degens DAO in 2026 is a useful case study. Their NFT metadata was originally pinned on an IPFS node hosted by Hetzner. Over time, that node became unreliable, and marketplaces started showing broken metadata. Because the contract's setBaseURI had already been permanently locked, they could not point the contract to a new IPFS location. Their only option was to recover the original directory CID byte by byte. The recovery process used caches from multiple gateways and a local backup made by one member in 2022. In the end, they pieced together all 10,000 files and re-pinned them to Pinata's paid infrastructure. Afterward, their improvements included redundant pinning across multiple providers such as Pinata, Filebase, and web3.storage, automated monitoring of gateway accessibility, and having multiple trusted holders keep offline backups of CAR files.

The lesson from this case is not "Pinata is safe." The lesson is that a single pinning point degrades over time. Nodes break, service providers change, and payments can stop. Redundancy needs to be spread across different failure domains: different providers, different geographic regions, and ideally offline copies that you control yourself.

Recovery: The CID Is Deterministic, but the Data May Not Be Findable

IPFS content addressing has a useful property: as long as the file content is byte-for-byte identical, re-adding it produces the same CID. A teaching example on GitHub demonstrates this: after unpinning and deleting the content, running echo with the same string and running ipfs add again produces exactly the same CID as before. This means that if you still have the original file, recovering the CID is deterministic.

But if you do not have the original file and only remember the CID, recovery is not guaranteed. You need to pull the data back from some node that still has those blocks cached. A gateway may have cached your file, but caching is not a pinning promise and can be cleaned up at any time. The Astar Degens recovery was difficult precisely because the original data was no longer pinned in any reliable place. They had to piece it together from scattered caches and private backups.

CAR files are a backup format worth knowing about. A CAR file packages an IPFS directory and all its blocks into a single file that you can store offline and re-import when needed. Astar Degens ultimately exported the recovered data as a 14.4 MB CAR file and uploaded it to Pinata. If you put important content on IPFS, exporting a CAR file regularly and keeping it in your own hands is more reliable than depending on any single pinning service.

A Deeper Solution: Filecoin and On-Chain Proofs

The official IPFS documentation positions Filecoin as a complementary layer for long-term storage: IPFS handles addressing, while Filecoin provides a storage protocol in which storage providers must regularly prove that they are still storing your data. Filecoin Pin is a tool launched in 2025 that packages IPFS files, uploads them to Filecoin storage providers, and requires providers to generate daily proofs of data possession. Payment is released only after on-chain verification passes. Its selling point is verifiable persistence: you are not trusting a service provider's promise, but rather cryptographic proofs and on-chain payment conditions.

However, this approach has costs. Filecoin storage requires managing deals, monitoring proofs, and handling renewals, which is not simple for ordinary users. It is also still a paid service. If you stop paying or the deal expires, your data faces the same risk of being cleaned up. If you just want a static website or a few documents to remain accessible long-term, Filecoin Pin may be too heavy. But if you need auditable storage that does not depend on a single company continuing to exist, it is worth considering.

Practical Guidance

If you are only sharing a file temporarily, a public gateway is enough and you do not need to pin anything. The file will survive in the gateway cache for a while, but do not expect it to stay forever.

If you have a file or static website that needs long-term availability, the lowest-cost approach is this: pin it with a paid pinning service such as Pinata or Filebase, and also export a CAR file to store locally. Regularly check whether gateways can access your CID. If you see timeouts or 504 errors, try another gateway. If multiple gateways fail, your pinning may have already failed, and you need to re-upload.

If you manage IPFS data referenced by on-chain contracts, such as NFT metadata, the redundancy requirements are higher. Keep copies with at least two or three different pinning providers, because once a contract locks its URI, you cannot change the address by updating the contract. The Astar Degens lesson is this: do not assume any node will stay online forever, and do not assume you will have time to recover calmly before the data disappears.

If you need verifiable storage that does not depend on a single company continuing to exist, Filecoin Pin is currently the tool in the IPFS ecosystem closest to that goal. But it is neither free nor maintenance-free. Accept those two points before using it.
