git-github-reflog

To recover lost commits after a hard reset, use the Git reflog to view the history of HEAD updates, locate the commit hash from before the reset, and reset your branch back to that specific reflog entry.

Yes, you can restore a deleted branch in Git by searching the reflog for the branch's last commit hash and using git branch to recreate it, pointing the new branch to that recovered commit.

Git reflog is a local record of updates to branch tips and HEAD references. It works for recovery by logging every commit update, allowing you to navigate and restore historical states that standard commit history no longer tracks.

To find a specific file version lost during a bad rebase, search the reflog for historical commit states, checkout the file from a previous reflog entry, and restore it to your working directory.

Git reflog is a local recovery mechanism tracking your repository's HEAD and branch updates. It recovers lost local commits, but remote recovery depends on the remote server's own reflog and branch history retention policies.

The main limitation of git reflog is that it only retains local history for a default period, typically 90 days. If a deleted branch or lost commit is older than the reflog expiration, it is permanently removed and cannot be restored.
