OS X V10.7 Lion :: Time Machine Corrupted Startup Volume - How To Reset Permissions
Jul 1, 2012
Running 10.7.4, MacBookPro Mid 2010. Â
After hardware failure (read heads on HD gave out. AppleCare replacement of HD. Third party data recovery and reinstall on my new HD.) I connected new Ext HD for Time Machine, and Time Machine has corrupted my startup volume.Â
Took to the repair shop and they said the Time Machine preferences file was corrupted, which left all my system drive data in a read-only state after backup. They trashed the pref file, and reset the permissions/read-only flags on my startup volume.Â
1) How do I reset the file permissions myself? (so I can nuke my Time Machine backup, manually back everything up, and manually recreate my entire system drive?)
2) Do you think since the data recovery place (Apple Authorized BTW) rewrote all my original data to the new HD, some "random" corruptions were copied over? Or is this a problem with Time Machine? (Which is why I want to do a manual reinstall/restore.)

Why is time machine saying that it cannot restore a file due to access persmissions when all I'm trying to do is restore a single file for my one and only user on the same computer that created the backup? Shouldn't that just work?

I have received warning from Disk Utility that I should repair permissions as several files show incorrect permissions and, more than that, my 750GB shows "769GB available".Â
1. If I use Command+R and rebuild the disk from a Time Machine backup, will permissions be reset or will the files just be copied as they are now?Â
2. Is there a way to verify the TM backups to check the files therein?Â
3. Suppose, just for the sake of an exercise, that I reload Snow Leopard; can I still use SL's Time Machine to read a Lion Time Machine backup?Â

I installed Snow Leopard, upgraded it to OS X 10.6.8, paid for and spent the hours necessary to download Lion, but Lion will not install. Even though it says the requirements are 10.6.6 or greater, when I try to install, I get a message saying I need 10.7. to install Lion.

Had to get my HD replaced in my iMac. Have been trying to get individual files off my Time Machine backup. Â
I go the "Browse other time machine disks" route but when it opens all it ever shows me is a single file with the name of my old HD. It won't display any files inside that volume. Â
I can "Show package contents" on the file itself to get to the files inside but it seems like some files are restored in time machine only.
Specifically the itunes library file gets broken into ,last, add , delete files, which my current iTunes install errors on when trying to import.

I'm moving from a MacBook Pro running 10.6.8 to a MBP running 10.7.5. I thought this would be pretty simple ... just attach my Snow Leopard Time Machine external drive to the Lion MBP and run Migration Assistant.Â
But when I go through the MA steps, MA does not see my TM drive. I've made sure I have the latest upgrades and have run Disk Utility's First Aid on the TM drive.Â
Ideas? I know I can try MA with other interfaces but using TM allows me to work on my old computer until my new one is ready.Â
The TM drive is a 500GB Iomega eGo drive.Â

if i am running my new lion OS on drive #1 and i have a Raid1 array on drive #3 and #4 with all my DATA - can i back this up using Time Machine? i would like to place my OS's on a single drive and have my DATA in a raid array but if this means that i lose the ability to retain a Time Machine backup of my data i will simply upgrade to Lion and keep the data on this drive so it can continue to get backed up in time.Â

I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.Â
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.Â
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of actionÂ
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

I've got an issue with time machine. It seems to be stuck at preparing backups for a long time, and after backing up, it indexes all the time. So a backup process takes about an hour. Started happening a few days ago. Using Airport Extreme with a disk connected over the network. Tried resetting and deleting the spotlight file as specified on pondini troubleshooting D2.
Here is a log file:
Starting standard backup
Attempting to mount network destination URL: afp://Chris@192.168.1.1/Time%20Machine
Mounted network destination at mountpoint: /Volumes/Time Machine-1 using URL: afp://Chris@192.168.1.1/Time%20Machine .....
Backup canceled.
Ejected Time Machine disk image.
Ejected Time Machine network volume.
I noticed that Time Machine-1 is mounted instead of Time Machine. Is this part of the problem.

I just wanted to add a sharing only user for my girlfriends new MacBook that she could use to connect to a shared Time Machine Volume. If I add a new standard user, this user can connect to my server via finder (connect as...) and see the shared drives. If the same user tries to connect to the Time Machine Backup Volume via the settings dialog, it receives an error message (OSStatus-error 5). If I add a sharing only user, this user cannot connect via finder or Time Machine (same error).
The clients console states the following error message:
/System/Library/CoreServices/NetAuthAgent.app/Contents/MacOS/NetAuthAgent[2471] AFP error -5018 mapped to EIO

I need to reset the permissions on my 10.7.3 lion software. Apple support has escalated this to software engineering levels and have not been able to give me a resolution. For some unknown reason all of a sudden my permissions would not allow me to properly move files to the hard drive. Also it would not allow me to take and move files around with the hard drive, it would just perform copies and not moving files to these locations - these were unexpected actions that were happening within the system.
I have worked with Apple support and have reset the ACL's using a root user this has still not resolved the problem. apple keeps escalating this issue up to higher levels of software engineering department however it takes 2 to 3 days every time to reply to me and this is unnerving.

It seems my system has reset something so admin-level users have read-only permissions for a pantload of files and folders. In every "get info" box the generic "admin" user has read-only priveleges. I can't stop and change permissions every time I want to work with a file.

I recently had the following experience, which is making me thinking about Local Time Machine Backups.Â
I have a MacBook Pro w Mavericks. I recently had an issue on my 40GB iPhoto Library and had to restore a previous version.
Since I was not at home (so without my Time Capsule), I firstly restored a local time machine backup of the previous day, which was created before the issue to my iPhoto Library. The old iPhoto Library was available by surfing on the local TM snapshots, however, after restore, I had the same issue: the library was corrupted. I tried a 2 days before local snapshot, without success.Â
Back home, I did a TM restore by using my Time Capsule TM backups, and the library is fully working, without any issue.Â
Since all the local backup that I tried to restore were related to dates where the iPhoto library was ok, I am wondering if there are any limitations or issues to local time machine backups.Â

Moved all my movies audio etc and stored on external HDD, but as I have lion and time machine it saved a local back up so that when time machine was synced it didn't miss anything.Seems sensible, so next step was to sync time machine, expecting that the local back up would disappear when it shifted to TM. It didn't...why in gods green earth is the local back up there even though TM connected the whole time and up to date? Â I've restarted, loaded all updates and verified disk. How do I get to the "it just works" part without having to Delete this double up (32GB "backups") via terminal etc....

I recently used Migration Assistant to make my new machine like my old one via TM. Now, all the permissions on more or less everything are messed up, and I can't change anything without going into Get Info and adding myself. I do not want to do this every single time I want to update an Application, for example. How do I do this "globally"- give my administrator account Read/Write permission for all of the normal things?
So far I have tried this: [URL]
Which did not work and returned this error:
Code: $ sudo chflags 0 /Volumes/Macintosh HD
sudo: can't open /private/etc/sudoers: Permission denied
I tried this: [URL]
Which resulted in this:
Code: $ sudo chown -R miles:staff /Users/miles
sudo: can't open /private/etc/sudoers: Permission denied
Why am I being denied permission using sudo? It doesn't even prompt me for my password. And now after restarting, I get stuck on the blue loading screen.

I performed an erase and install of Snow Leopard and then used Migration assistant to transfer all my data back to my computer. After that I noticed that on my 2 other internal hard drives, most of my folders had a red minus sign over them and when I clicked the folder it said "The Folder can't be opened because you don't have permissions to see its content". I clicked get info and under sharing and permissions there was a name that said "unknown". was this the newly created account which I had deleted? Afterwards I added my account and applied it to all my files and folders. I can now access all my files and folders. But now my question is weather or not my files became corrupt or was it just a permissions issue? Also What caused the permissions issue in the first place?

I searched MRoogle already, I didn't find anything quite like what my problem is.
I know you can change it by editing the plist, com.apple.backupd-auto.plist. However, I am unable to save it even if I do the following:
Code:
LaunchDaemons $ sudo chown [my username] com.apple.backupd-auto.plist
LaunchDaemons $ sudo chgrp admin com.apple.backupd-auto.plist
Of course, I changed it back to root and wheel, respectively. What did I miss?
This article, for instance, does not even mention the fact that root owns the plist!

I have a g5 ppc running the newest OSX. Somehow my startup folder got corrupted and my computer would not start up. so I did a restore from time machine. The restore worked ok. I have 2 external hard drives attached to my computer, one for time machine and one for iTunes and movies. After restore and restart my computer said the hard drive attatched could not be repaired by disk utility. I did not ask it to fix anything. Now, I don't have permission to write to my external hard drive on the non time machine hard drive. When I get info, the lock on the bottom is not available, and I can't modify anything. Can I fix this by going into the terminal?

I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?

I have two 750 gb drives that I want to put together as a JBOD as a Time Machine volume. Is there an advantage to having the drives in an external enclosure, such as this one, vs. inside my tower? If inside the tower, I'm concerned that if there's a failure of my boot drive that I would lose the JBOD TM backup.

Time Machine has been running fine for a week now. Suddenly, today, I get this error message:
The Machine Error
The backup volume is read only.
To select a different volume, open System Preferences and choose Time Machine.
I didn't change anything to make it read-only, and it's far from full.

I just got my Mac back from a repair at the Apple Store. I was very excited to have everything back. However, Time Machine cannot back up! The error given is that the backup volume "cannot be found."
I've tried rebooting, remounting the drive and doing checks on it. Everything checks out. I can even write and read to and from the backup volume just fine via Finder. The only issue is that Time Machine can't. What's the problem? How do I fix it?
Attached is a screenshot of my Finder window next to the Time Machine Sys Prefs window.

I have been backing up my computers to an external HD with Time Machine for some time, but I just bought a 1Tb Time Capsule today. Is there a way to move/copy my existing TM backups to the new drive (in the Time Capsule), rather than starting a whole new backup, so that I can preserve my existing TM 'history'? I could just start a new backup, but it would only back up the 'current state', and I would lose all the prior data.

I lost an external hard drive due to failure. Luckily, I found out that for some reason Time Machine had backed up the drive's volume along with my startup internal drive.Now I just want to restore that lost drive's volume folder from Time Machine to a NEW external drive. However, I imagine that if I merely click "Restore" from Time Machine app it will attempt to put this volume (which is 100GB) onto my internal drive.
Is there a way to direct the location of the restore of that volume folder to my new external drive? Or can I just go into my Time Machine Backup drive and drag and drop the volume contents from the Time Machine volume onto it?

I needed to change my backup volume's name. Now it's not recognized by TimeMachine any more. It seems I can only choose this volume again AND delete older backups, which I do NOT want.Â
How can I just continue on this volume with its new name?
