3.2. Restoring a corrupt Library in Volocity

Restoring a corrupt Library in Volocity

A Volocity library is an essential database that combines image data and metadata. If a library becomes corrupt, it may be difficult or impossible to fully restore the data without a proper backup. For this reason, frequent backups of critical data are highly recommended. Both the .mvd2 file and its corresponding Data folder must remain intact for the library to function properly.

Why Volocity Libraries Are Difficult to Restore:

• The files in the Data folder do not merely store raw image data; they are interlinked with metadata in the .mvd2 file to create a functional database.
• Without both the .mvd2 file and the complete Data folder, the library cannot function, and it is not possible to extract and import the files into another library.

Steps to Attempt Restoring a Corrupt Library:

If the library is corrupted but still recognized by Volocity, you can try the following procedure:

1. Open the Corrupt Library in Volocity:

   • Launch Volocity and attempt to open the corrupted library.

2. Compact the Library:

   • Go to the File menu and select Compact Library.
   • In the Compact Library dialog box, check the option Also remove cached data and preferences.

3. Start the Compacting Process:

   • Click Compact to initiate the process.
   • This operation will clean up the library by removing unnecessary cached data and attempting to optimize the library's database structure.

4. Assess the Restored Data:

   • Once the process is complete, review the library to see if the corruption has been resolved and if your data is accessible.

Best Practices for Preventing Corruption:

1. Backup Regularly:

   • Always maintain regular backups of your Volocity libraries.
   • Store backups in a secure, redundant location (e.g., external drives, cloud storage).

2. Avoid System Interruptions:

   • Do not shut down the workstation or interrupt Volocity while saving or compacting a library.

3. Monitor Disk Health:

   • Use tools like CrystalDiskInfo or your system's built-in diagnostics to monitor the health of your storage drives.
   • Replace failing drives promptly to prevent data loss.

4. Limit Concurrent Access:

   • If libraries are stored on a shared network drive, limit simultaneous access by multiple users, as this can increase the risk of corruption.

Final Note:

If the above steps do not resolve the issue, and no backup exists, the corrupted library may be irrecoverable. In such cases, consider reaching out to Volocity support or IT professionals with experience in data recovery for further assistance.
