Azure File synce error

Question

Hi,

I am getting Persistent sync errors for my file share. I tried to solve that by following the remediation. I am not able to solve that. From server it's showing me no error for syncing.

Thank You!

@Anonymous Based on the error message Rename the file or directory in question. See Handling unsupported characters for more information. ERROR_INVALID_NAME 0x8007007b

Azure File Sync agent v17 supports all characters that are supported by the NTFS file system except invalid surrogate pairs.

If the portal or FileSyncErrorsReport.ps1 PowerShell script shows per-item sync errors (error code 0x8007007b, 0x80c80255, or 0x80070459) due to unsupported characters, check whether Azure File Sync agent v17 is installed on the server. If agent v17 is installed and files still fail to sync due to invalid characters, use the ScanUnsupportedChars script to rename files that contain unsupported characters.

For more information refer to this troubleshooting articles : https://learn.microsoft.com/en-us/troubleshoot/azure/azure-storage/file-sync-troubleshoot-sync-errors?tabs=portal1%2Cazure-portal

Note: Once a sync session is completed, the Persistent sync errors and Transient sync errors counts in the portal are updated. If a sync session is in progress, wait until the sync session is completed and the Persistent sync errors and Transient sync errors counts are updated before you investigate the remaining errors.
