Introduction

If you notice that a file is stuck in the Pending list with a yellow exclamation icon, it indicates that Polarbackup may be having trouble backing it up. Below are common causes for this issue and their respective solutions.

 

Cause A. Outdated Polarbackup Desktop Application

To resolve issues with an outdated Polarbackup application:

 

1. Download the latest Polarbackup setup file:

2. Run the downloaded setup file and select the Repair/Update option.

 

Cause B. Files Backed Up via Block-Level Technology

Files backed up using Block-Level Technology are uploaded once every 24 hours. Please wait for the scheduled upload time for these files to be processed.

 

Cause C. Polarbackup Unable to Copy Files

If Polarbackup cannot copy files to the cache folder, verify that there is sufficient free space on the drive where the cache folder is located or change it.

 

Cause D. Volume Shadow Copy Service (VSS)

Polarbackup relies on VSS to back up open and locked files. To ensure proper backup:

 

  • Add frequently open files to the VSS extensions list.
  • Verify that the VSS service is running correctly or requires repair. Follow the steps outlined here if necessary.

Note that the VSS service does not support files on external or network drives.

 

Cause E. Permission Issues

Ensure you have full or at least read permissions for the file, folder, or directory intended for backup.

 

Cause F. Network or External Drive Issues

Check that the network or external drive where the files are stored is connected, accessible, and not in use by other processes.

 

Cause G. Failed to Upload

For files that remain in the Pending list due to upload failures:

 

  • Verify your Internet connection and router settings to ensure they are not blocking Polarbackup from uploading files.
  • Ensure your firewall and antivirus settings are configured to allow Polarbackup.
  • Apply the troubleshooting steps here.

 

Cause H. File Has a Long Path

Due to operating system limitations, Polarbackup cannot back up files with paths exceeding 250 characters. To resolve this, shorten the file path. (Learn more)

 

Polarbackup will make subsequent attempts to upload these files during each run. If the problem continues, please contact the Technical Support Team at support@polarbackup.com.
