  4. Disk Drill: Disk Drill is another user-friendly option that supports a wide range of file systems and storage devices. It offers both free and paid versions, with the paid version providing more advanced recovery options.
  5. TestDisk: An open-source tool, TestDisk is highly effective for recovering lost partitions and making non-booting disks bootable again. It's more technical and suited for users with some IT knowledge.
  6. PhotoRec: Often used in conjunction with TestDisk, PhotoRec is another open-source tool that specializes in recovering lost files, including photos, videos, and documents, from various storage media.

What should I do immediately after experiencing data loss?

Experiencing data loss can be stressful, but taking immediate action can significantly improve your chances of successful recovery. Here are the steps to take right after data loss:

  1. Stop Using the Affected Device: As mentioned earlier, immediately stop using the device to prevent overwriting the lost data. This is crucial for increasing the chances of recovery.
  2. Disconnect the Device: If possible, disconnect the storage device from the system. For example, if it's an external hard drive, unplug it. If it's an internal drive, shut down the computer.
  3. Assess the Situation: Quickly assess what might have caused the data loss. Was it a sudden power outage, a virus, accidental deletion, or physical damage? This initial assessment can guide your next steps.
  4. Do Not Attempt DIY Fixes: Avoid trying to fix the issue yourself, especially if it involves physical damage to the storage device. Incorrect handling can lead to further data loss.
  5. Contact Professionals if Necessary: If the data loss is due to physical damage or if the data is critical, consider contacting professional data recovery services immediately. They have the expertise and tools to handle complex recovery scenarios.
  6. Use Data Recovery Software: If the loss is due to software issues or accidental deletion, use data recovery software. Install the software on a different device and connect the affected storage device to it. Follow the software's instructions to scan and recover the lost data.
  7. Document the Incident: Keep a record of what happened, including the date, time, and any error messages you encountered. This documentation can be helpful if you need to involve professionals or for future reference.

By following these steps, you can take immediate and effective action to recover your lost data and minimize the impact of the data loss event.

What is GTID (Global Transaction Identifier) and what are its advantages? What is GTID (Global Transaction Identifier) and what are its advantages? Jun 19, 2025 am 01:03 AM

GTID (Global Transaction Identifier) ??solves the complexity of replication and failover in MySQL databases by assigning a unique identity to each transaction. 1. It simplifies replication management, automatically handles log files and locations, allowing slave servers to request transactions based on the last executed GTID. 2. Ensure consistency across servers, ensure that each transaction is applied only once on each server, and avoid data inconsistency. 3. Improve troubleshooting efficiency. GTID includes server UUID and serial number, which is convenient for tracking transaction flow and accurately locate problems. These three core advantages make MySQL replication more robust and easy to manage, significantly improving system reliability and data integrity.

What is a typical process for MySQL master failover? What is a typical process for MySQL master failover? Jun 19, 2025 am 01:06 AM

MySQL main library failover mainly includes four steps. 1. Fault detection: Regularly check the main library process, connection status and simple query to determine whether it is downtime, set up a retry mechanism to avoid misjudgment, and can use tools such as MHA, Orchestrator or Keepalived to assist in detection; 2. Select the new main library: select the most suitable slave library to replace it according to the data synchronization progress (Seconds_Behind_Master), binlog data integrity, network delay and load conditions, and perform data compensation or manual intervention if necessary; 3. Switch topology: Point other slave libraries to the new master library, execute RESETMASTER or enable GTID, update the VIP, DNS or proxy configuration to

Why is InnoDB the recommended storage engine now? Why is InnoDB the recommended storage engine now? Jun 17, 2025 am 09:18 AM

InnoDB is MySQL's default storage engine because it outperforms other engines such as MyISAM in terms of reliability, concurrency performance and crash recovery. 1. It supports transaction processing, follows ACID principles, ensures data integrity, and is suitable for key data scenarios such as financial records or user accounts; 2. It adopts row-level locks instead of table-level locks to improve performance and throughput in high concurrent write environments; 3. It has a crash recovery mechanism and automatic repair function, and supports foreign key constraints to ensure data consistency and reference integrity, and prevent isolated records and data inconsistencies.

What are the transaction isolation levels in MySQL, and which is the default? What are the transaction isolation levels in MySQL, and which is the default? Jun 23, 2025 pm 03:05 PM

MySQL's default transaction isolation level is RepeatableRead, which prevents dirty reads and non-repeatable reads through MVCC and gap locks, and avoids phantom reading in most cases; other major levels include read uncommitted (ReadUncommitted), allowing dirty reads but the fastest performance, 1. Read Committed (ReadCommitted) ensures that the submitted data is read but may encounter non-repeatable reads and phantom readings, 2. RepeatableRead default level ensures that multiple reads within the transaction are consistent, 3. Serialization (Serializable) the highest level, prevents other transactions from modifying data through locks, ensuring data integrity but sacrificing performance;

What are the ACID properties of a MySQL transaction? What are the ACID properties of a MySQL transaction? Jun 20, 2025 am 01:06 AM

MySQL transactions follow ACID characteristics to ensure the reliability and consistency of database transactions. First, atomicity ensures that transactions are executed as an indivisible whole, either all succeed or all fail to roll back. For example, withdrawals and deposits must be completed or not occur at the same time in the transfer operation; second, consistency ensures that transactions transition the database from one valid state to another, and maintains the correct data logic through mechanisms such as constraints and triggers; third, isolation controls the visibility of multiple transactions when concurrent execution, prevents dirty reading, non-repeatable reading and fantasy reading. MySQL supports ReadUncommitted and ReadCommi.
