Unable to Request a DB Dump – “Already One in Progress” Error During Backup

Original Question or Issue:

I encountered the following error during backup without making any changes

Environment:

  • Product - FileCloud Server
  • Version - 23.253
  • Platform - Linux

Steps to Reproduce:

 

Error or Log Message:

Backup Filecloud Server Logs showing:

 

2026-03-09 1:36:37.569447 ERROR: [1288032][17730381973631] Unable to request a db dump. Already one in progress. rc=1 []

Defect or Enhancement Number:

 

Cause:

This error typically occurs when a previous backup job failed or was canceled, leaving behind a database dump lock file.

Because the lock remains in place, FileCloud assumes another database dump is still running and prevents new backup jobs from starting.

Resolution or Workaround:

  • Check if any backup job is currently running.

  • On the FileCloud server that is being backed up, locate the following directory:

     /var/www/html/scratch/dbdump*

  • If no backup job is currently running, the directory can be safely removed.

         Example:

     rm -rf /var/www/html/scratch/dbdump*

  • After removing the lock directory, stop any pending or stuck backup jobs.

  • Start a new backup job from the backup server.

Notes:

  • Always confirm that no backup job is actively running before deleting the dbdump* directory.

  • This issue is typically caused by interrupted or failed backup operations that leave the lock in place.
