First of, I would like to thank @uroni and everyone else involved in developing and maintaining this great software!
We’ve got a QNAP TS-873 as the backup server (v2.4.12) and 5 Windows (10 and 7) clients (v2.4.10) backing up to it, doing only image backups.
3 of the clients (all of which are in “Internet Mode”) have a recurring error (Backing up System Reserved (SYSVOL) partition failed. Image backup failed) each time a backup occurs (whether it’s Full or Incremental) and we can’t figure out how to fix it (although the backup always succeeds after a retry, but it’s annoying and the 2 other clients don’t have this problem).
Things we’ve tried:
- Disable IPv6.
- Disable any Offload / Green Ethernet / Any Other “Network Optimization” options in the Network Adapter settings in Device Manager.
- Change “Transfer Mode” settings (Raw / Hashed).
I’ll post the debug log of one of the clients (Windows 7 64-bit).
Any help would be greatly appreciated!
EDIT: We’ve just updated the server to v2.4.13.
EDIT2: Attached another log from a different client (Windows 10).
