Review Comment:
The trailing slash should ideally not be necessary. I'd prefer to just drop
it and we deal with the consequences. **If** needed, the previous code was
clearer IMO so I'd rather see something similarly clear.

Assuming that actually works, I think a little comment is needed like

Review Comment:
why trim after we've called normalize? If trimming had been first thing;
probably needs to continue to be first thing. I don't like trim in most places
including here though (it's generally sloppy); in a major version we can get
away with dropping it.
+1 to Eric's comment. And no need to call normalize at this spot.

Review Comment:
This beginning of this method is awkward. Ultimately we want to resolve
path against SolrHome, while insisting that path is relative, even if an
absolute path was passed in. (gosh I wish a comment was there saying this). I
kinda wish we could declare that as a requirement to callers so they didn't
pass absolute paths (up to you; maybe scope creep). So we strip off any
leading path separator chars, thus converting it to a relative path. If we do
that, UNC will be impossible.

Review Comment:
Do not pre-compute this stuff; it should only be calculated/fetched when the
metric is fetched. Maybe could clarify that the TODO is to move metrics
initialization to after data directory initialization, thus avoiding this
exception (hopefully) but that may not be entirely possible.

No Eric; the BackupRepository abstraction is based around URI & String. We
could change it (maybe that's your proposal) but that's a big change that
