Recover Specific Data by Using Git Commands

Employ Git Recovery Commands

When working with Git within Azure Repos, it is essential to understand how to recover specific data to maintain repository integrity and support continuous integration workflows.

Trace and Recover Data

One effective way to trace commits and recover data in Azure Repos is by using the git reflog and git log commands. These commands help locate missing history:

• git reflog: It logs all reference updates in your repository, allowing you to see adjustments even for orphaned and deleted branches.
• git log: This command shows the commit history of the repository, which can be useful to track changes over time.

Restore Files and Branches

To restore files or branches, you can apply several commands with appropriate options:

• git checkout: Useful for switching branches or restoring files to a previous point in their commit history.
• git revert: Reverts the changes introduced by specified commits without removing them from the history, which is useful in undoing changes in a safe manner.
• git reset: Can be used to move the current branch tip backward to a specified state, either modifying the index or working directory.

Retrieve Stashed Changes

For retrieving stashed changes or isolated patches, you can leverage:

• git stash: Temporarily stores modified tracked files so you can work on something else and reapply those modifications later.
• git cherry-pick: Allows you to apply the changes introduced by existing commits onto your current branch. This is particularly helpful for selective application of bug fixes or features.

Understanding and effectively utilizing these git commands will enhance your ability to manage repositories, ensuring robust and reliable development workflows in Azure DevOps environments. Using these commands maintains repository integrity and facilitates seamless continuous integration.

Conclusion

In summary, mastering Git recovery commands is crucial for effectively managing data in Azure Repos. Tracing commits using git reflog and git log helps locate missing history. Commands like git checkout, git revert, and git reset are essential for restoring files or branches, ensuring developers can undo changes safely. Finally, retrieving stashed changes using git stash and applying selective patches with git cherry-pick enhances flexibility during development. These tools ensure robust repository management and support continuous integration workflows.
