Bitdefender prevents Time Machine back up with MacOS Monterey

Hi, I've just installed MacOS Monterey, whilst running Bitdefender Total Security. All seems fine, except the Time Machine back up has stopped working, and Bitdefender reports:

"An unauthorized app attempted to access your backups.

App: /System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd

We blocked the app to prevent it from altering the content of your backups."

Is this a glitch I can fix, or does it require an adjustment to Bitdefender??

Many thanks, Richard

  • Hello @Richard101 ,

    Thanks for pointing this out. The issue has been resolved in the cloud, no product update is required, at most please run a manual update to make sure everything, including signatures, are up to date.

    cheers,

  • I had the same problem. Did a google search and had to go into my library find a plist file for time machine , delete it and re enable the backup. it seems to be working now, ,but I have also turned off the Bitdefender protection of Timemachine. I really wonder why that is such a problem. OH and now bitdefender is continuously scanning that I went from big sur to monterey. Me thinks someone needs to figure out why things don't work as well and why I am getting fewer updates of new whatever to bitdefender. something isn't happy.
  • Hi @josephatoubes ,

    We've just released a hotfix in the cloud, if everything is updated, then should work fine.

    cheers,

  • Hi @rchapl ,

    If after the all the updates the behaviour is still the same, then please contact our Support team by visiting https://www.bitdefender.com/consumer/support/

  • I have the same issue and my build number is current (9.0.1.8). OS Monterrey 12.0.1

    Jerry

  • Same here, but I think I got around it by unchecking Don't scan content in backups in Preferences.


  • I had a similar Monterey-Time Machine issue to the original post but with Bitdefender initial blocking a different system app.:

    "An unauthorized app attempted to access your backups.

    App:/System/Library/PrivateFrameworks/DiskImages2.framework/Versions/A/XPCServices/diskimagescontroller.xpc/Contents/MacOS/diskimagescontroller

    We blocked the app to prevent it from altering the content of your backups."

    Before seeing the response from @Mike_BD I choose to allow the file in Anti-Ransomware. This didn't work. Ran database update as suggested by @Mike_BD but now getting the following notifications in Anti-Ransomeware:

    "An unauthorized app attempted to access your backups.

    App: /usr/libexec/diskimagesiod

    We blocked the app to prevent it from altering the content of your backups."

    Any thoughts?


  • I too got bitten by the same thing. The worst was that Monterey was also grouping/hiding the notifications from Bitdefender, so I was left in the dark. Plus, if I'm not mistaken, blocking Time Machine happens even when you "Turn OFF Bitdefender Shield" from the menu bar --- I cannot verify now because finally I managed to start a backup! --- but I have already tried that because Monterey does show a notification mentioning that it is possible an antivirus blocked the backup process, so I thought of giving a shot with "Turn OFF Bitdefender Shield", but no go.

    For anyone out there googling stuff that happens in the Console, you might see the following which should help you out finding this thread.

    • The file “com.apple.TimeMachine.MachineID.bckup” couldn’t be opened because there is no such file.
    • The file “com.apple.TimeMachine.MachineID.plist” couldn’t be opened because there is no such file.
    • No such file or directory.
    • Failed to attach using DiskImages2 to url '/Volumes/.timemachine
    • Operation not permitted
    • Couldn't open 'Info.plist' with flags 0x102

    Turning off "Time Machine Protection" under "Protection - Anti Ransomware" did the job. I still have "Don't scan content in backups" enabled as opposed to another user's post above.

    Having this type of issue makes it hard to keep continuing to recommend Bitdefender to other MacOS users.

  • Hello @andreineculau ,

    We're preparing a release adressing:

    - the cache of scanned files is not created on macOS 12

    - miscellaneous Time Machine Protection, Safe files improvements

    - miscellaneous macOS 12 compatibility improvements

    Cheers,

  • Hi,

    I too have this problem - very annoying. When will the fix be released?

    Mike

  • Just upgraded to Monterey on MBP 2017 and also set up Time Machine to backup to Synology 1821+. Received the same error that everyone else has pointed out above regarding Bitdefender blocking ransomware and the backup process. After turning off Time Machine Protection I was able to restart the Time Machine backup from my MBP and it works fine. Bitdefender should provide a way to allow this protection while whitelisting the process/destination backup folder.

  • Having the same issue and not able to back up to time machine. @Mike_BD please let us know when this is going to be resolved?

  • I've got 9.0.3.3 and it just started happening to me. I can no longer back up my computer. Come on. Fix this!

  • Updated to 9.0.3.3, still have same Time Machine backing up issue.

  • Getting the same issue on 23 December 2021 with Mac OS Monterey and a MacBook Pro 14" connecting to a Time Machine drive/folder on a Synology NAS.

    "An unauthorized app attempted to access your backups.

    App: /usr/libexec/diskimagesiod

    We blocked the app to prevent it from altering the content of your backups."

    I also noticed Bitdefender thinks my subscription/product has expired even though I still have coverage for another couple of years... confirmed on Bitdefender Central. Maybe a restart will fix it.

  • Hi,

    I had the same problems as everyone else including it saying that the product had expired (it hadn’t). A complete uninstall and reinstall fixed it for me.

    Instructions Below from there own site.

  • After all steps done still have this issue on my NAS.

  • Has this been Fixed yet? I still have Time Machine Protection disabled. AFAIK, I have everything up to date.

  • I have Catalina OS, I can't update further because of the age of my Mac Mini (late 2012).

    I've spent many hours trying to figure out Time Machine not backing up, from late December onwards. I seem to have overcome the problem by switching off the the Bitdefender Anti-Ransomware Protection for Time Machine.

  • When the fix is available, will it work with Catalina OS?

  • @indiabravo the fix is available for Catalina OS as well.

    If anyone is still encountering this issue, please let us know.

    Cheers.

  • What fix?

    I seem to have got back-ups to Time Machine working again by uninstalling the software - "Toolkit" - that came with my LaCie back-up disc.

  • Update 9.0.4.2 is available gradually. Please let us know is issues persist and we will continue to monitor.

    cheers,

  • Hi @Mike_BD

    I attempted to back up to Time Machine today using a NAS, and Time Machine Protection prevented the attempt.

    I turned Time Machine Protection off, and the backup was completed successfully.

    Surely I should not have to turn off Time Machine Protection every time I wish to back up my computer? Or worse, turn it off permanently?

    Thanks
