Is there a way to restore an annotated tag? One was accidentally deleted and pushed. I can restore normal tags by just using git tag again, but for an annotated tag, there's a tag object and I'm not sure how to restore it.

If the tag still exists, `git fsck --unreachable | grep tag` should show you output listing the dangling tag objects. Once you have that list, use `git show SHA1` to view the object. When you find the tag, make a reference to it with `git update-ref refs/tags/NAME SHA1`.

Thanks, that worked.
One thing I noticed that I wasn't sure about is that I SSH'd into the server and ran git update-ref to restore the tag. That created the symbolic name in .git/refs/tags/NAME to point to that tag object. But what I noticed is that the only file listed in .git/refs/tags is the tag I restored. There are other tags in the repository (and a fresh clone gets them), but they don't show up in that directory. Is it going to be a problem that ran git update-ref on the server (which is a bare repository) rather than on a clone that I push? I just want to make sure that the tag objects are referenced so they don't go away after the 2 week garbage collection grace period.

The other tags are in the .git/packed-refs file.

No.
