Show HN: ZeroFS – Make S3 your primary storage

I assessed the tool on a CentOS 7 system today. It can't run on older CentOS 6. It will generate core dump.

My testing went well. I was able to mount ZeroFS as NFS and write a 100M file to the mount point. The file persists after I deleted ZeroFS cache.

My plan is to use it for backup process. If we don't have such tool, we would need to prepare a large Filesystem stage area, then run rclone to upload to cloud space. With this tool, I can mount it on Backup server, rsync file server a large Filesystem to the ZeroFS mount point, eliminating stage area.

Will ZeroFS support large Filesystem size about 800GB?

Perhaps your cpu is too old? The prebuilt binaries require newer CPUs but you can build your own.

Absolutely, and much, much more than that.

Glad to hear it can support large file system. Is ZeroFS stable with:

Millions of files, Interrupted transfers, Backup Server Reboots, Long-term operation?

Yes, that should work fine!

Is this only was S3 or any S3 compliant service? Does it support any sort of storage tiering ?

Any S3 compliant service.

Yes, it has a local cache that's populated on reads, but no writeback cache yet.

better than juicefs and without the macfuse shennanigans ?
