Version 133. Windows 7 64 bit.
1) Setting the backup location never sticks, it always is empty when returning to the screen.
2) Once a full backup has completed to a network device, it is impossible to do a differential backup because CB does not see ANY devices on the network for step 3, though there are several present. There NEEDS to be a "Browse" key on this screen! Note that CB does see the devices under Restore and at Step 1.
3) Sometimes CB simply hangs, showing spinning gears
You can try the 4.0 version
here.
It should have issues fixed.
Regarding issue number 2). You can also perform a differential backup by simply choosing the same source and the same destination file. The differential backup will be appended to existing backup file.
Thanks
