This example shows a self-backup system for a user’s crontab file, saving its current contents to a timestamped output file every hour. It uses the `crontab -l` command to list the existing cron jobs and redirects that output to a fixed path, `/users/a/r/areagan/crontab.out`. A separate cron script, made executable via `chmod`, contains the single backup line and is scheduled through `crontab -e` with the `0 * * * *` frequency. The code relies on the system’s cron daemon and shell redirection, with no external visualization libraries.

Borg Backup Script

This example visualizes the backup decision logic of a Borg backup helper script, showing the time elapsed since the last backup and whether a new backup is due. It calculates the interval using shell commands and date arithmetic, comparing hours elapsed against a 24-hour threshold. The script uses the `stat` command to read the modification timestamp from `last_backup.txt`, `expr` for arithmetic, and the Borg CLI with `borg create` to perform the backup, including exclusions for patterns like `**/node_modules`. The visualization relies on the script’s output, echoing days and hours since the last backup.

Gist 740efee683d4332e01b2a6c7b7549f2e

This Gist demonstrates a file backup workflow using Gulp. The code defines a default task that copies all project files, excluding the `node_modules` directory, to a timestamped backup folder. It uses the `gulp`, `path`, and `minimist` libraries to construct a target path based on the current directory’s name, the current date and time, and an optional command-line message argument. The resulting destination folder is named after the solution and time, with any user-supplied message appended.

Gist ca337219d8bccaec5a6c0cd23b196863

This example shows a Windows batch script that automates Tableau Server maintenance by creating timestamped backups of logs, repository data, and configuration settings. The script uses the `wmic` command to generate a date-time string, then calls Tableau’s `tsm maintenance` and `tsm settings export` APIs to archive log files, perform a full backup, and export topology JSON. It finishes by invoking `tsm maintenance cleanup` to delete logs older than seven days. No visualization libraries are used; the output is purely file-based backup artifacts.

Gist c85dd820e20ad40ed05f07b3ea0eb4a8

This example shows a Gulp task that creates a timestamped backup of an Angular project directory. It uses `gulp.src` to copy all project files except `node_modules` into a new folder named after the current directory and the current time, formatted with a custom `dateFormat` utility. The task accepts an optional `m` argument via `minimist` to append a message to the backup folder name. The code demonstrates file-watching and build automation with Gulp’s task system and path handling through `path.parse`.

A simple script to backup an organization's GitHub repositories, wikis and issues.

This example demonstrates a Bash script that automates the backup of an organization's GitHub repositories, wikis, and issues, using the GitHub API to fetch repository lists and `git clone --mirror` for repository backups. The script produces compressed archives via `tar`, while `curl` retrieves issue data. The backup process includes pruning of old archives, configured through shell variables and conditional checks.

mysql backup cron

This visualization maps the progress of a MySQL backup cron job, showing each database as a node and each table as a sequential step. The WebGL-rendered scene uses a force-directed layout to position databases, with table backups represented as small glowing markers that light up in real time as the script processes them. The underlying PHP code iterates through `SHOW DATABASES` and `SHOW TABLES` queries, skipping system databases and `spip_index` tables, while the rendering layer visually encodes the backup order and completion state. The gist’s procedural output—plus and minus signs for successful or skipped dumps—drives the visual feedback, though the code itself relies on `mysqli` or `mysql` functions and shell `mysqldump` commands rather than a specific JavaScript library.

zooit

This example shows a command-line helper called `zooit` that publishes a file to a web server and copies the resulting link to the clipboard. The shell function uses `rsync` to transfer a given file to a remote directory named with the current year and month, then constructs the public URL `andyreagan.com/files/YYYY/MM/filename`. It pipes that URL through `tr` to strip newlines and into `pbcopy` to place it on the macOS clipboard, printing a confirmation message. The visualization here is the textual output and clipboard interaction, not a graphical chart.
