While Time Machine suddenly starts to create a image with a 1 in the filename (which fails), I can't seem to show Time error 45 creating backup disk image Machine it has already a working image without the 1. I tried to point again to the Time Capsule disk, but no luck. Since a few Macs backup over the internet it's no option just to erase all the images and start over again. Anyone tips? Mac mini, Mac OS X (10.6.7) Posted on Jan 20, 2012 8:38 AM I have this question too by Jim Nijkamp,Solvedanswer Jim Nijkamp Level 1 (15 points) A: In the end I did the following steps: - copy original backup images to a local disk;- totally reset (and format internal disk) the TC to original settings;- configure TC again;- put back the backup images from local disk to TC.Now it works ok again. Still no clue what was going on. Notice that sometimes the TC gives errors back to the clients for a day or so. I don't do anything and everything returns normal again after a few days. Weird...

from the Adobe Community Summit I knew there were a couple of things I had to do. Getting a bit of rest and hanging out with my wife and son were at the very top of the list.
The Shared Protection Point Operation Failed With Error 0x81000101
Closer to the bottom was plugging my MBP into a power brick in order to windows backup timed-out before the shared protection point was created. backup my computer to my Time Capsule. Little did I know it wasn't going to be as easy as usual.After plugging in and initiating creation of the shared protection point timed out. unknown error (0x81000101) the backup, Time Machine took over 20 minutes to prepare the data - it simply displayed "Preparing data" for what seemed like ages. Finally, it finished the prepare data phase and displayed how much data it was backing up, https://discussions.apple.com/thread/3669865?start=0&tstart=0 about 5.3 GB. I'm simply amazed that one weeks worth of work could generate 5.3 GB of changed data. Realizing it was going to take Time Machine quite a while to copy 5.3 GB wirelessly to the Time Capsule I shut the MBP's screen about 80% of the way and decided to return to the living room to do other things.A few hours later I came back to my MBP to see the following message:First, many thanks to Apple http://www.aaronwest.net/blog/index.cfm/2008/5/18/A-Fix-for-Time-Machines-Backup-Failure for giving me a useful error message I could do something about. Pfff. I tried several things to get Time Machine working again including rebooting, reconnecting to the Time Capsule, and simply restarting the backup process. All failed with the same error message.After hitting up Google for answers (Google always seems to have answers you know) I found a few posts on the MacCast forums that seemed promising. A user by the name of "karinlord" deserves credit for the right set of steps to mitigate this problem.I believe my problem started when my computer decided to sleep in the middle of the backup process. I am unsure if this occurred because of my systems preferences or whether I actually shut the computer lid enough to force it to sleep. Regardless, Time Machine seems to freak out if it gets interrupted during the backup process. When this happens several files and folders are left on your backup volume that deter any subsequent backups.To get Time Machine going again, you need to remove the errant files with the following steps:Ensure your backup device is turned on and connected to your computer (wirelessly or wired, it doesn't matter)Turn off Time Machine using the big button in Time Machine preferences. NOTE: I did not execute this step and was still able to fix Time Machine.Make sure the backup volume (which is just part of the backup drive) is

If I partition the drive on OSX first (hfsplus, no journaling), then mount it under Linux, chmod & chgrp it to the TimeMachine userID, and share with netatalk, then I get the same error you report (after "preparing backup", error is "Setting security information: Operation not permitted"), and backup fails every time. However, if I stop netatalk, repartition the USB drive to a single EXT4 partition, mkfs.ext4, remount and chmod, chgrp, and share with netatalk, then I do not see this erro
