> How to get a list of all NOT unused files
There may be a simpler way, but one idea:
* list all unused keys
* list all present keys
* filter out the unused keys from the present keys
So something like this:
```
$ git annex findkeys | sort >present-keys
$ git annex unused --json | jq -r '.\"unused-list\" | to_entries | map(.value) | .[]' | sort >unused-keys
$ comm -2 -3 present-keys unused-keys
```
> Those that should be saved are tagged
If you wanted to focus just on keys referenced from tags, you could
generate a list of those keys with
```
$ git rev-list --objects --no-object-names --no-walk --tags | \
git annex lookupkey --ref --batch | grep -v '^$'
```
---
After generating a list of keys with either of those approaches, you
could copy them to your new repo with
```
git annex copy --to=NEW-REMOTE --batch-keys ...
```
For example, the full pipeline for the second approach could be
```
$ git rev-list --objects --no-object-names --no-walk --tags | \
git annex lookupkey --ref --batch | grep -v '^$' | \
git annex copy --to=NEW-REMOTE --batch-keys
```
