Question about long-term pinning and file availability on BTFS

Hi everyone,

I’m currently testing BTFS v2.3.4 for a personal decentralized storage project and I’m curious about file persistence over time.

If I upload and pin a file locally using my node, but the node is offline for a while, is there any way to ensure that the file remains accessible on the network?
Do I need to manually pay for hosting with a third-party host node, or are there any built-in mechanisms for replication? Speed Stars

Also, are there any active projects or communities using BTFS for long-term archival use?

Thanks in advance for your insights!
