Find a file by filename anywhere

[enboig]

I have lost a file, and I don't know which host was, neither the folder; I only have filename. How can I find it? Mounting everything and using find isn't the most efective way.

rustic find --glob <FILENAME>, e.g. rustic find --glob file.txt.

If you can specify a filter to e.g. rule some snapshots out, use this to make the search faster, e.g. rustic find --filter-path /snap-path --glob ...

If you even know the exact path (within the snapshots), use
rustic find --path <PATH>, e.g. rustic find --path /my/path/to/file.txt
