Identify what needs protection

An application usually needs more than a database: uploaded files, private configuration, the code version and necessary keys. The backup inventory must reflect those dependencies. Copying only the database can leave records pointing to missing files.

Define acceptable data loss and recovery time. Those requirements guide the backup schedule, version retention and storage locations.

Restore in an isolated environment

Periodically use a backup to rebuild the application in a separate environment. Check the data, attachments and important workflows. Do not practise against the database serving users.

Record the time required and any manual steps. If only one person knows how to restore the system, that is another operational weakness to address.

Protect the backup itself

Backups often contain sensitive data. Restrict read access, keep them outside public directories and use an appropriate retention period. Check deletion of older copies carefully so the only usable backup is not removed.

After major storage or schema changes, review the recovery guide. Code, database and files must be compatible; reverting only one part can make the situation more complicated.
