Scenario: AI gained access to the database and executed TRUNCATE TABLE users. How to restore the data?

Answer from AI
If the command TRUNCATE TABLE users is executed, the data from the table is deleted without the possibility of rollback within a single transaction, as TRUNCATE usually does not support rollback.
Recovery options:
-
Restoring from a backup — the most reliable method. Find the latest database backup and restore the table or the entire database to the point before deletion.
-
Using transaction logs (if configured) — in some DBMS, point-in-time recovery (PITR) can be applied to revert the database to a state before the TRUNCATE was executed.
-
If replication or change logging is enabled — attempt to extract data from the replica or logs.
-
Using backup or data archiving systems — if configured, data can be restored from there.
Example of restoring from a PostgreSQL backup:
pg_restore -d your_database backup_file.dump
