I screwed up the excel spreadsheet at work.
I sorted a column, and saved it. I thought it was going to sort the whole thing based upon that column, but it just changed the order of the column and none of the surrounding data. Apparently the ?computer guy? says the tape back up failed. Why are we using tape back up anyway, isn?t HD space just as inexpensive nowadays?
So, does Excel save a copy on the drive or is there a way to undo or something besides relying on the tape back up? BTW, the "undo" button is no longer highlighted, so I am not sure how one would undo at this stage.
