I see what is going on. The problem is not the snapshotting, but the backups to this file. I assumed the discussion of autosave was referring to worksheet.txt in all these tickets, but it is this mysterious file. Since it wasn't that big of a file, I thought maybe it wasn't the problem. (Out of curiosity, does this file also have any of the permissions for notebooks? Probably irrelevant.) > > I set the autosave interval on sagenb.org to once per *day*. > Again, I remember that discussion, but didn't realize there were two different autosaves going on here. > > 3.

I will relay this to sysadmin AND try some of this out on my laptop, and hopefully that will solve it. I hope the "tangle of tickets" gets resolved soon, though unfortunately I am not competent to try - just competent enough to make a well-intentioned mistake, instead!
