Why Do SQL Backup Files Become Corrupted?
.sql dump files can become partially or fully unreadable due to an interruption during database backup, a transfer error (a corrupted transfer over FTP/email), a disk error, or incorrect character encoding.
Typical Scenarios Encountered
- The backup process was interrupted midway, leaving the file incomplete
- Character encoding was corrupted during file transfer
- The file was partially damaged by an email/disk failure
- It is unclear which database engine (MySQL, PostgreSQL, MSSQL) the backup file belongs to
Approach
The file's structure is analyzed to identify the point of corruption, and as much data as possible is recovered or made importable.
How Does the Process Work?
File Analysis
The file format, source of the issue, and solution path are determined through a free preliminary analysis.
Analysis Result
The expected success rate and timeline are clearly communicated.
Recovery
Following approval, the recovery process is carried out based on the analysis results.
Delivery
The recovered file is delivered to you through a secure channel.
The preliminary analysis and demo recovery are always free. If, after the demo stage demonstrates that the content is recoverable, you choose not to proceed with the full recovery, a fee of 250 USD + VAT applies, covering the analysis and demo work already performed.
Database content is not of interest; only the requested technical operation is carried out. The file may need to be opened to the extent required for recovery verification, but its content is never copied, shared with third parties, or retained on our systems after delivery. If requested, a written confidentiality commitment is also provided.
Frequently Asked Questions
Which database engines do you support?
.sql files originating from MySQL/MariaDB, PostgreSQL, and MSSQL can be worked on.
Is 100% recovery guaranteed?
It depends on the extent of the corruption; how much can be recovered becomes clear after the preliminary analysis.
