SD Hang

[Frank]

Hello,
This is the first incremental "smart" backup I have tried. The message during the backup now which has persisted unchanged for the last ten minutes is "Copying files from...
86,740 of 460,644 files evaluated, 1,250 files copied...2.82 GB evaluated, 2.38 GB already up to date, 367.82 MB copied." The progress bar isn't moving and when I try pusing the "stop" button, I get a message warning that I would leave the target volume in an unknown state. Suggestions?
Frank
