adminWhat Website Backup Means
A website backup is a recoverable copy of the important parts of a website. It should include files, database, uploads, configuration and enough information to rebuild the site.
Where Backup Sits In The Stack
Backup sits across the whole infrastructure. It protects application files, database content, uploaded media, server configuration and business continuity.
How Backup Works
A backup process copies website files and exports the database on a schedule. A strong backup system stores copies outside the VPS and tests whether those copies can be restored.
Why Backups Fail
Backups fail when they only copy files but not the database, stay on the same server, are never restored, exclude uploads, or run out of disk space during backup creation.
How To Think About Backup
Backup is not complete until restore is tested. A backup file that cannot rebuild the website is only a false sense of safety.

Core Concept
Backup is the recovery layer that allows a website to be rebuilt after failure, attack, migration error or data loss.
System Role
It protects the business continuity of the website by preserving files, database, uploads and configuration outside the live system.
How It Works
The system exports the database, copies website files, stores them safely, and uses a restore process to rebuild the site when needed.
Connected Components
WordPress files, uploads, MySQL database, wp-config.php, Nginx config, SSL notes, cron jobs, offsite storage, restore environment.
Common Failure Points
Files backed up without database, backup stored only on same VPS, no restore test, missing uploads, corrupted archive, failed scheduled backup, full disk during backup.
Verification Method
Verify backup existence, file size, database dump integrity, offsite storage, restore test and recovery time after a simulated failure.
Basic Commands
ls -lh /var/backups;
mysqldump --version;
tar -tzf backup.tar.gz | head;
mysql --version;
df -h
