    File History no longer working

    I've been using File History for awhile now and really like it. However, I've noticed in the last couple of days that it's no longer backing up files. Even when I click the Run Now link, it will say it's backing up files, but new files don't show up when I go to Recovery and the date/time of the last update doesn't change. (It has actually disappeared as I've tinkered.)

    None of these things has helped:
    * Turning File History off and back on
    * Rebooting the computer
    * Disconnecting/reconnecting the external hard drive
    * Freeing up space on the external hard drive (I have 1.63 Tb free on a 2 Tb drive.)

    I'm running Windows 8.1 with all patches.

    The event log includes the following:

    Any ideas?

    Have you tried changing how long File History keeps files?

    Have you tried cleaning up older versions of files backed up by File History?

    Thanks for the suggestions. I tried both things to no avail.

    However, this morning I did some more searching online and discovered a workaround, which was to find and exclude the folder that was causing the error. In my case, this was the Photos library, although many of the posts I read talked about the Music library. I'm not sure what in my Photos library causes File History to choke, but at least I'm back to having everything else backed up (and I've done a manual backup of that library).

    Did you figure out it was Photos by trial and error?

    Have you added a large number of files to Photos recently?

    Have you edited files in Photos recently?

    Yes on the trial and error thing. I excluded one library at a time and ran a backup to see what would happen. Fortunately, I didn't have to do a deep dive.

    I haven't made any changes that I can think of since backups stopped working.

    Thanks for the update.

    After you removed it from the backup criteria and ran a backup, were all the backed up files in Photos deleted from the backup location? If so, have you since tried to re-add Photos and see if it is miraculously fixed?

    Hi, Joe. Yes, the excluded files were deleted from the backup location (which sort of surprised me). When I added the library back to the backup set and ran it again, it worked like a charm! I guess I just have to monitor File History from time to time to make sure this doesn't happen again. It doesn't do a good job of error reporting, to say the least.

    Thanks so much for all the ideas!

    Nice detective work and follow up. I suppose something got corrupted on the backup disk. Since there is no public documentation I know of which describes how File History really works we don't have any good way diagnosing problems. We can just hope that Microsoft will fix this sort of problem over time.
