Overview

Introduction:

1. Backup is initializing...
2. Backing up the information of storage device...
3. The volume 0(C :) is backing up.
4. Backing up data...
5. Information Code: 10105
6. Failed to create file.

Solution 1: Check permission, antivirus, and destination path

Solution 1:

First, check the following items:

1. Check whether DmAgent.exe is blocked by your antivirus software. Run DmAgent.exe by start "Disk Master Agent" service from the service manager. If it is blocked, allow it in your antivirus prompt or security settings.
2. If you are backing up to an external drive, check whether the drive is disconnected or whether its drive letter has changed. Reconnect the drive and make sure it uses the same drive letter as the destination path in the backup task.
3. If the NAS connection fails, delete nas.dat from C:\ProgramData\Disk Master, and then reconnect the NAS by entering its IP address. This can fix connection issues caused by an unstable network or changed user account credentials.
4. Make sure the destination location has enough free space to store the backup image file.
5. If you are creating a full, incremental, or differential backup from an existing backup task, make sure the task is still valid. Use the "Check Image" option in the Advanced menu. If the task is invalid, reload it and try again.

Solution 2:

If the error occurs while backing up to a NAS or shared drive, confirm that the target location is connected successfully. The computer or NAS that hosts the shared folder may be shut down, disconnected, or unavailable on the network. Reconnect the destination before running the backup again.

For Qiling Disk Master v3.2 and earlier, you can also try the following method.

Map the NAS/Share (network drive) as a local drive in Windows

To map your network folder, refer to the screenshot below and follow the Windows mapping process.

After the folder is mapped successfully, you can select it as a backup destination in the same way you select a local drive.
