Question

Backup Failed Agent: Failed to process method {Transform.Patch}: Cannot create a file when that file already exists.


Hi, 

I’m seeing the following error for just one of our offsite backups. The local backups are working as expected.

Agent: Failed to process method {Transform.Patch}: Cannot create a file when that file already exists. Asynchronous request operation has failed. [requestsize = 4202496] [offset = 706145980416]
Processing finished with errors at 18/11/2024 05:41:10

This issue is only occurring on our SQL server. A 2019 Windows Server.

Any troubleshooting pointers will be greatly appreciated.  

Thanks

What version of Veeam are you using?  Did you check the logs for more details?

Logs - C:\ProgramData\Veeam\Backup\Jobname

If this is a backup copy can you try doing a full sync or backup to see if starting a new chain fixes it?

Hi Chris, 

I looked in the logs, and found nothing matching the error. 

I’ll try the full sync/backup now, and report back.

Thank you.

Ok sounds good.   If there are still failures then it might be better to open a support ticket for further troubleshooting.

Do you have any backup health checks setup? What’s your backup chain and retention looking like?

@dips Thanks for your reply. 

We’re set with a Remote Backup Per Device Repo, with 10 days retention. Backup health checks were not set by the MSP when this was implemented.

With this being our offisite backup, I’m able to dispose of the date and configure a fresh job for this. 

Would you recommend doing so, and choosing to enable out the periodic health check option?
