The error wording, time, and destination are the best evidence for choosing a next step; there is no single verified fix for every failure. The checks below separate backup-run problems from rescue-media errors and recovery actions.
1. Find the failed run’s status and log
In Backup Pro 27, open Backup Plans and locate the affected plan. The plans area shows each plan’s status. Open the plan details and select the relevant log entry to display that run’s backup log, as described in the Ashampoo Backup Pro 27 manual.
- Record the plan name and its displayed status.
- Open the log entry matching the failed run and note its timestamp and complete error wording.
- Record the destination selected by the plan: local storage or cloud storage.
- Use the error and destination to decide which checks below apply. Avoid treating a guess about the cause as a diagnosis.
The available documentation does not identify one universal cause or remedy for failed backup runs. If the log does not make the cause clear, use Ashampoo’s official support index to find a relevant support article or contact support with the recorded details.
2. Check whether the PC and storage are supported
Ashampoo’s Backup Pro 27 requirements, reviewed October 4, 2026, list the following constraints. They are compatibility checks, not proof that any one of them caused the failure.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Windows edition: Windows 10 or Windows 11, 64-bit.
- Processor and server support: ARM systems and Windows Server are unsupported.
- Permissions: Full administrative rights are required.
- Partition and device size: Partitions or storage devices sized 8 TB or greater are unsupported.
- Activation: Internet access is required for activation, and the license is verified periodically.
If your system or the relevant storage falls outside these stated requirements, first confirm that you are running the supported setup. A failed run alone does not show that a requirements limit is the cause.
3. Verify the destination and its access
Backup Pro 27 supports local and cloud destinations. For cloud storage, the manual says credentials are required; sign-in generally uses the standard browser, except for WebDAV. Check the destination that is actually set in the affected plan rather than assuming it is the same as another plan.
Rank #2
- 5-in-1 USB-C Hub: Experience comprehensive connectivity featuring a Power Delivery input, two USB-A 2.0 ports, a USB-A 3.0 port, and an HDMI port. (Note: The USB-C power delivery input port is only for connecting an external wall charger to power your laptop and cannot power peripheral devices.)
- 90W Pass-Through Charging: Achieve optimal charging with 90W pass-through power to your laptop, supported by a total input of 100W, with the hub reserving 10W for operational efficiency. (Note: Wall charger not included.)
- Quick Data Transfers: Accelerate your productivity with rapid data transfers using a high-speed 5Gbps USB 3.0 port and two 480Mbps USB 2.0 ports.
- 4K HDMI Display: Enhance your visual experience with a hub capable of delivering 4K resolution at 30Hz in both mirror and extend modes. Please note that this hub is compatible with MacBook (macOS 12 and newer), Windows 10 and 11, ChromeOS, and laptops equipped with DP Alt Mode and Power Delivery. Note: This device is not compatible with Linux.
- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
- Local disk: Confirm the selected drive is connected and accessible.
- Network destination: Check that the location can be reached and that the required account has access.
- Cloud destination: Confirm the account credentials still work and that the service is reachable.
- Capacity: Check that the destination has enough available space for the backup you are attempting.
The manual does not establish a universal free-space threshold or a single network fix for all destination errors. Use the log’s wording to narrow the issue; the documentation does not rank local and cloud storage by reliability.
4. Run a disk check only when storage symptoms point there
If the source or destination drive is reporting problems, use Backup Pro 27’s Check disks area. The manual describes options to check drive health and find or repair errors. This is a targeted step for storage-related evidence, not a general fix to try for every failed backup.

5. Treat rescue-media errors as a separate problem
Creating rescue media is different from running a backup plan. Backup Pro 27 uses the Windows Assessment and Deployment Kit (ADK) for rescue-system creation. Ashampoo’s manual specifically warns that existing but outdated ADK components may cause errors during that process.
- In Windows, open Settings > Apps > Installed Apps.
- If present, remove Windows Assessment and Deployment Kit and Windows Assessment and Deployment Kit Windows Preinstallation Environment Add-Ons.
- Retry rescue-media creation.
This ADK guidance applies to errors while creating rescue media, not to ordinary failed backup runs. The manual also says the ADK can be downloaded on another machine if the connection is slow. If creating rescue media on a flash drive larger than 32 GB, be aware that the program reduces its primary partition to 32 GB; use a drive whose contents can be erased.
Rank #4

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
6. Understand backup-format trade-offs
If you are reviewing or changing a plan’s backup format, the manual describes two trade-offs. Format choice affects how backups can be browsed and what metadata they retain; it is not, by itself, a documented general remedy for failed runs.
| Format characteristic | More accessible format | More efficient format |
|---|---|---|
| Browse in Windows Explorer | Yes | No; accessible only in Backup Pro 27 |
| Storage use | Uses more storage | Uses less storage |
| Extended file attributes | Does not retain them | Includes them, such as permissions and symlinks |
7. Restore only when you intend to recover data
Restoration is not a diagnostic step for a failed backup. The manual distinguishes file restoration from partition or disk restoration: file restore lets you select files and folders, while restoring a partition or disk overwrites the existing target with the backup contents.
Best Value
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.

- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
For system recovery, the rescue medium requires a previous backup created with Backup Pro 27; the manual says a full drive or partition backup is ideal. Before starting a partition or disk restore, verify that you have the correct backup and target and understand that existing target contents will be overwritten.
