Files Changed while Executing Backup Plan (code 1629)

Situation

The "Some files from the backup dataset were changed while executing the backup plan." warning message appears while running plans in Backup Agent on UNIX-based operating systems.

Cause

Certain files could be modified while backup data is being uploaded. There is no snapshot creation tool for UNIX-based systems, and as a result, these files were skipped.

Solution

Solution 1 (Simple)

Do not back up files in use.

1. Edit the backup plan in the Management Console or in the Backup Agent instance on the computer.
2. Enable the Do not back up files used by other processes at the moment of the backup plan run option in the backup plan wizard.
3. Finish the wizard and run the plan again.

Solution 2 (Advanced)

Read the following article to understand what should be included in the backup scope. Exclude affected program data folders from the backup dataset. For the rest of the skipped files in the backup datasets (you can see the list of these files in the last run message), you should use workarounds. If some applications use files you want to back up, refer to the documentation of these applications for information on how to create backups or dumps of these files in a specific location.

1. Create a script that creates a backup or dump file in the specific location.
2. Edit the backup plan in the Management Console or in the Backup Agent instance.
3. Add this location to the backup scope on the What To Back Up or Backup Source step of the backup plan.
4. On the Pre /Post Actions step, enable the pre-backup action.
5. Select Exit backup plan if pre-backup action failed.
6. Add the created script as the pre-backup action.
7. Finish the backup plan wizard and run it again.

You can find the backed-up copies of the required files in the location you have selected for dumps or backups.
