Backup Failed; Error Not In Manual

Win7x64 Home Prem
N360 w/Backup installed/configured

Incremental Partition C, Track 0, and MBR backup was scheduled for 0630. When I checked PC around noon, CBU2 was prompting me for COS login; I entered name/password but it failed.

The 0630 backup failed, “Last Run Status: 3”, which isn’t listed in the online manual. CBU gave no other indication that the backup failed (no red X, no dialogs).

In trying to zip the logs, my right-click in Explorer caused explorer to hang; I had to reboot. CBU and COS shell extensions are enabled.

Thank you for the logs.
The issues with error code 3 and explorer hang will be fixed in next release.
