May 6th, 2023 ~ 5 Minutes Reading
Database restoration is a critical task in any organization. That relies on a database management system to store and manage critical business data. While database backups are an essential part of any data recovery strategy, sometimes restoring a database backup can result in errors and failures. One such error is “SQL database cannot be recovered because the log was not restored.” In this article, we will explore the causes and solutions to fix this issue.
Causes of “the database cannot be restored because the log was not restored” Error
When attempting to restore a database backup, the database management system (DBMS) requires both the database backup file and the corresponding transaction log backups to be restored. The transaction log backups contain all the changes made to the database since the last full or differential backup. If the transaction log backups are not restored, the database cannot be brought to a consistent state, resulting in the “database cannot be restored because the log was not restored” error.
There are several reasons why transaction log backups may not be restored, such as:
- Missing Transaction Log Backups: If one or more transaction log backups are missing from the restore sequence, the database cannot be restored to a consistent state.
- Corrupted Transaction Log Backups: If one or more transaction log backups are corrupted, the database cannot be restored to a consistent state.
- Incorrect Backup Sequence: If the transaction log backups are not restored in the correct sequence, the database cannot be brought to a consistent state.
