When Vim Crashed and My Unsaved Article Disappeared

Two days ago I opened my computer, launched a terminal and, as usual, started writing an article with Vim. The writing progressed smoothly and the draft was nearly finished.

Just before wrapping up, I tried to open a virtual machine to fetch an illustration, but the VM hung and the whole system froze. With the mouse and keyboard unresponsive, I forced a power‑off and rebooted.

After the reboot I realized the article had never been saved. Opening the file showed it was completely empty, and all the content I had written was gone.

Normally Vim can recover unsaved work via its swap file ( .swp), but earlier I had disabled the swap‑file feature because the .swp files cluttered the directory. That decision left me without any chance of recovery.

Without a swap file or any automatic backup, I could only rewrite the article from memory, which was tedious and broke the original flow of ideas.

The incident reminded me of an earlier experience on a server where I edited a configuration file without making a backup; when the service failed I had to manually roll back changes, causing a noticeable outage.

Since then I have adopted a habit of always backing up files before modifying them—whether on a server, in a script, or when writing documentation—by copying them with a timestamped name.

The lesson is clear: features like Vim’s swap files may seem unnecessary, but when a crash or unexpected termination occurs they can be the last line of defense. Therefore, enable recovery mechanisms, save frequently, and back up critical files before making changes.
