When backing up clients over wifi, I get the error “Checksum for image block wrong. Stopping image backup.” Is there a fix or setting I can try to avoid this?
If you can recompile you could increase this one: https://github.com/uroni/urbackup_backend/blob/dev/urbackupserver/ImageBackup.cpp#L54 (
max_num_hash_errors after which it stopps the backup is 10 per default).
I’d look into updating wifi drivers/devices to stop the network corruption. It is not normal and probably causes problems in other areas as well.
Finally, you could connect your client via Internet mode. The encryption/compression there will take care of network corruption.
I agree that stopping the network corruption is best, but the device and access point are using the latest driver/firmware.
How do I force the Internet mode for a machine on the LAN?
"C:\Program Files\UrBackup\enable_internet_only.bat" as admin on the client is an easy solution.
Got it! Thank you so much.
I confirm that using the internet mode solved the data corruption during upload on several machines connected via wifi.
