I've dabbled in both Garage and RustFS. Both are good but IMO flawed.

Garage is good but has weird tooling and a terrible searchable term. You'll receive lots of garage doors and electrical gate results when searching for issues with it.

The biggest problem with Garage is the metadata on an sqlite. If you have a single file and that sqlite corrupts then all your data is unaddressable and treated as pile of anonymous blocks. If you have multiple servers you can rebuild the metadata but if you have only one server you REALLY need to make sure that file is backed up.

So if you use S3 as a backup you have to keep a backup of your backup.

RustFS is closer to Minio, but I hate the way they log stuff. They basically use journald as a metric database dumping json formatted lines about library calls and how long they took. Its hard to make sense of those logs. Its the kind of log not meant to be human readable but to render on a dashboard.

Why not just publish these as a prometheus endpoint?

Also high CPU usage for no reason. I also noticed RustFS constantly trashing disk and keeping 10% CPU usage while looping some health check I have no idea how to disable (I've tried RUSTFS_SCANNER_ENABLED=false and others with no results). And of course lots of json metrics on journald.

I personally prefer garage because my backup box sit at my office and I like not needing to listen to HDD sounds all day every day while Rustfs loops its health check.
