====== Nginx Log Rotation Script ======


==== Overview ====

This Bash script is designed to manage and rotate Nginx log files. It ensures that logs are periodically backed up, cleared, and maintained efficiently by keeping only the latest backups.




==== Script Functionality ====


=== 1. Define Log File Paths: ===


  * Sets up paths for access and error logs.
  * Specifies a directory for storing log backups.

=== 2. Verify Log File Existence: ===

  * Checks if the `access.log` and `error.log` exist.
  * If either file is missing, the script exits with an error.

=== 3. Backup Logs :===

  * Creates a timestamp (`YYYYMMDDHHMMSS`) for log backups.
  * Copies the current logs to the backup directory with a timestamp suffix.

=== 4. Verify Backup Success: ===

  * Ensures the backup process was successful.
  * If the backup fails, the script exits with an error.

=== 5. Clear Log Files: ===

  * Empties the access and error logs to free up space.

=== 6. Backup Retention Management: ===

  * Keeps only the latest 7 backups.
  * Deletes older backups beyond the set limit.

==== Script Link ====

==== Conclusion ====

This script automates the log rotation process for Nginx logs by ensuring efficient backup and cleanup. By maintaining only the last 7 backups, it helps manage disk space while ensuring log history is available when needed.
