(31) A device attached to the system is not functioning

[MrPineapples]

Hi,

I've been trying to get Reflector to backup my PC for a couple of weeks now.

I am running Windows 11.
I have a network attached device mounted as a share.
I can manually copy files to it with Windows Explorer.
I am running incremental backups.

The backup copies some files and directories and fails on others.
The failure message is always the same:
ERR 2022-09-04 05:02:16 The directory "\\<pcname>\<directory>" couldn't be created: (31) A device attached to the system is not functioning: [\\<pcname>\<directory>]
I check the NAS after the backup fails and I can copy files to it just fine.

If I run it multiple times, it will get further through the backup. It takes about a week to backup the 47GB running once a day.

Any ideas on what can be causing this?

Thanks

My guess is that the program is running as a service and not as an application.

It is running as an application.

No idea. If you can work with the SMB partition manually, it should work as an application as well.
