Cannot access folders in Time Machine back-up drive

I have used Time Machine to back up our server for months. Now I need to go and try to retrieve a lost file. I can see the folder the file should be in but I get an error that tells me that I do not have permission to access the folder. The folder has a small red circle with minus sign in lower left corner. I am logged in as the Server Administrator so I should have full permissions to everything.
Does anyone have any suggestions as to how I can change the permission status of the folder in the back-up?
Thanks in advance,
Brian

I am accessing through the TM interface. The TM interface has multiple folders on this particular weeks back-up. Some I can access and get to the files inside and some I do not have access to. Unfortunately, the folder I want to access and find the single file contains over 200,000 files. If I were to restore the folder, it would overwrite three months worth of files and make them outdated. I need to get access into the folder and restore that individual file.
Is there a way to restore on a second external drive to keep out current files in tack?

My MacBook w/ OSX 10.6.8 cannot access my external Time Machine Backup USB Drive. It says it is a Read Only drive. When I went to change permissions I found all pernissions were listed as "Custom" and I could not reset them to "Read Write". Any help!

This can be done easily with ethernet.
Please follow the instructions strictly.
To make it easier I want you to do this overnight so you can turn off all your current connection to the internet.
Just go to the airport fan in to the top right and turn airport off.
Get ethernet cable and connect the laptop to the TC lan port.. ie <-> ones.
Press and hold the reset on the TC for about 10sec. until the front led flashes rapidly.
Open the airport utility.. go to manual setup and change the wireless to off. (so other people around you cannot join your network of one).
Ignore all the errors.. they won't stop the backup working.
Go to the TM and reselect the backup target disk as the TC.
It should start after 2min and run through to completion.
That is it.. for a backup of many GB it might take a few hours.. so make sure the laptop has power plugged in and the sleep is off.. (on early ones I think this is needed but I am a late arrival to the scene).. sleep doesn't affect later OS.

I would like to access an old Time machine back up from a Core 2 Duo Macbook, but no longer have a Mac. Can I access the backup from a cheaper old ibook, or would I need a Macbook. Is the OS important?

right click on the folder that shows with the red negative sign, and select to "get info". In the long skinny window that appears, look in the "sharing and permissions" section. In the "name" column, you should see your current user name. Ensure the "privilege" is set to Read and Write. If your user name is not in the name column, click the + sign, and add it, ensuring the privileges are set to Read and Write

i previously posted this question, but I mistakenly clicked my own comment as the correct answer. i think this makes the thread appear to be finished; so, because i'm still not completely sure what to do, i have attempted to copy and paste the discussion here:Sorry.
Just got Prosoft drive genius 3 software, and it's telling me that the external hard drive that i am using for my time machine back up drive needs to be defragmented. is it wise to do this or should i not??

If your backups take a few seconds longer, so what. I say leave it alone.Beige G3, G4/867, G4/dual 1.25 MDD, MacPro'09 w cheap SSD, Mac OS 8.6 or Earlier, and 9.2, 10.5 and Server - LW IIg, LW 4/600, ATalk ImageWriter L

Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd. Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set. 1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price. I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there. Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB? Best would be to ask in the TimeMachine section Snow Leopardhttps://discussions.apple.com/community/mac_os/mac_os_x_v10.6_snow_leopard?view= discussions#/?tagSet=1009where there are some good FAQ and tutorials, and people that know the ins-and-outs and shortcomings.

my boot drive is my internal hardrive which is a 250 GB drive. The drive i am using for TM is 500GB, but you are saying that is really too small. TM, as i understand it, creates a copy of everything, and then subsequent backups record any changes that were made since the last backup. and what do you mean "bootable clones" and do you mean for my internal hard drive AND each of the 3 external hard drives that i have? i'm using one of the three for backup using TM, and i am storing movie files on the other 2. i work at a church, and we use many short films that we purchase online. i then import that file into iMovie to give my volunteers a consistent second and a half of black before the clip and 4 seconds of black at the end of the clip. This provides smoother transitions, i've found, than trying to use most of the clips in their original form. i then have been filing these away in folders on the other 2 hard drives. Regarding the TM drive. Drive Genius is telling me that "the used space on the volume 02 [that's the name of the drive] is 25% fragmented (59.14% of total space).
btw, Time Machine keeps:hourly backups for the past 24 hoursdaily backups for the past monthweekly backups for all previous monthsand the oldest backups are deleted when your disk becomes full.
Mac Pro, Mac OS X (10.6.8), LaCie d2 Quadra 500GB external driv

1st) A fragmented drive is not evil. It will not hurt anything. At worse it might slow down reading a file. However, as has been pointed out by others in this thread, who cares as this is a backup device, not a device you are going to be reading a lot.
2nd) The time you spend defragmenting the drive will far exceed the time you will save when writing new data to the drive.
3rd) Defragmentation will just increase your energy consumption, as all the reading/writing needed to move the files around in order to defragment it, will cause the drive to consume more energy than if it was just sitting idle waiting for the next hourly Time Machine backup.
4th) Defragmentation (if done frequently) may shorten the life of your drive. Not mentioned in "3rd" above is that the extra energy used translates into heat, plus you are moving the read/write heads back and forth all of which affect the drives mechanical and electrical components.
NOTE: There are situations where having a defragmented drive is useful, but mostly it has to do with needing to stream media at a high rate of speed, and fragmented files can affect that. However, a backup drive being used for incremental Time Machine backups is not in that category, and most home Mac usage does not need a defragmented file system either.

Time Machine Back-Up Drive Question

Is it possible to use the Time Machine External Drive for storing information aside from back-up files, while using it for Time Machine at the same time? For example, I collect live shows of a certain band. Would it be possible to store the music files on the Time Machine Back-Up drive and still be able to use the drive for Time Machine? Thanks in advance.

No problem but I suggest this:
Create a folder for you personal backups and put everything in them.
TM will create a unique folder for itself and it will be happy with that.
I have, on my G5, a TM drive that also has several old backup folders, (Not TM) which live perfectly with TM.
Just don't put anything into the TM folder.!

Has anyone successfully used a "WD My Book for Mac" via NAS (plugged into USB port on router) as a Time Machine back-up drive?

Has anyone successfully used a "WD My Book for Mac" via NAS (plugged into USB port on router) as a Time Machine back-up drive? Apple support tech tried to tell me it wasn't possible and that the only NAS Time Machine could back up to is the Time Capsule, but I'm not buying it. I know it's doable, but I'm having a hard time figuring out which External HDDs will work and which ones won't. If not My Book for Mac, is there an External HDD that will work? (Running OS X 10.9.1 - Mavericks, btw...)

Given the nature of backups, my recommendation has always been to use a strategy that is unequivocally supported by Apple. As you already determined Apple Support unequivocally informed you that your proposal will not work, unless your router is an Apple AirPort Extreme or Time Capsule.
The exhaustive list of devices supported by Time Machine amounts to the following:
AirPort Time Capsule's built-in hard disk (any model)
External USB hard disk drive connected to a Time Capsule (any model)
External USB hard disk drive connected to an AirPort Extreme (current model only)
A hard disk drive directly connected to your Mac
That is all.
Use whatever backup device you want, but you should be aware that this site is full of reports of misery from hapless individuals who had been using NAS devices for Time Machine backups, only to find that they were incomplete, corrupted, or useless when they were required. Apple won't care if you lose your data while using a Time Machine configuration specifically excluded from their technical support documents.

Running more than one time machine back up drive

I have a back up drive assigned as my offices time machine back up drive.
I need to set up an off site back up drive too. I know that time machine will only allow a connection to one back up destination at once.
What problems could i encounter if i set up a off site drive as another time machine drive, disconnect on site drive and connect the off site drive to back up.
Thanks

That will work just fine, other than the hassle of having to tell Time Machine every time you swap.
Give the drives at least slightly different names (that's for you; Time Machine knows they're different).
Each set of backups will be complete and independent. When you do a backup to either one, it will contain all the changes you've made since the last backup +*to that drive.+*
The first backup after a swap may take a bit longer than usual, as there may be more changes to "catch up" with, but otherwise there should be no troubles.

The disk drive in my iMac 8,1 has stopped working, so I now use an LG 8x Slim Portable that works. However, every time I use the LG drive, I lose contact with my Time Machine back-up drive that has to be deleted and reinstalled. Help!

It's not Logic that can't find them, it's your Komplete apps, though if you did exaclty as you say I can see no reason why they can't.
Do you know where the apps installed them in the first place? I chose a non-standard locarion for mine, but I'm sure it installs sounds to your documents folder/native instruments/name of app.
Go into the prefs of each app and choose the library location button on the library tab and point it to the relevant folder in documents/native instruments and see if that works

That's not needed, but if you want to do it, use the Disk Utility in the /Applications/Utilities/ folder to create a new partition.

Access mailboxes in time machine back up

My hard drive crashed and I had to replace it with a new one.
On my previous drive I was running Mountain Lion, I upgraded to Maverick on the new drive.
I have my previous drive backed up on time machine, but was unable to restore from a time machine back up, before installing Maverick (files corrupted)
I absolutely need to get back my old mailboxes from Time Machine !
How do I access the hidden library in my time machine back up?
Now that I have Maverick, it is not entering my Mountain lion back ups when I enter time machine.
The back ups are of course vivible on my finder desktop on the back up drive.
Is there a way to access the hidden library in the time machine back up without entering time machine?

Copying folders from time machine back up to other Mac

Hi,
I used Time Machine to back up my laptop (running Leopard) on a portable drive. I would like to copy a folder (containing hundreds of files) from the Latest Backup to a different mac (running Tiger). When I copy the folder, all that appears is an alias (indicated by an arrow in the bottom right corner). I tried holding down the option key while copying, no luck, the copied folder is still an alias. Any suggestions on how to get an actual copy and not an alias? (I cannot copy the individual files over, that would work, there are too many). Thanks

annalisac wrote:
Since this folder contains data that get updated daily and is used by a common software on both computers, I was hoping not to have to manually copy that folder every day on the external drive, but simply to retrieve it from the Time Machine back up. Thanks for letting me know.
you can use different software for backing up this folder. CCCloner can do it although it's not very suitable for backing up single folders. or try Chronosync.

How do I retrieve my iphoto library from the Time Machine back-up drive, when the original iphoto library was on a separate external hard drive that has crashed?

I recently backed up my iMAC and Simpletech external hard-drive to a 1 TB WD Passport external hard drive, using Time Machine's back-up utility. Today, I tried to access my iphoto library from the back-up drive, but received a message saying "the iPhoto library is a Time Machine back up, and so cannot be used as the main library. Relaunch iPHoto with options key held down to choose another library." Since my Simpletech died on me, what other iPhoto library is it expecting me to access? I know approximately 169 GB were backed up, and my iPhoto library is roughly 54 GB.
Angie in Charlotte

Thanks. I will try going through TM. Since my Simpletech is on the way out, I'll be plugging in a new external hard drive (other than the back-up drive) and trying to restore the library to the new drive. Any advice or warning if this is NOT the right thing to do?
Meanwhile, that is a great tip to do an alternate back-up using a different means. It's been tough to figure out how to "preserve access" to digital images and files for posterity, knowing the hardware will always fail/obsolesce sooner or later, and that "clouds" are only as good as their consistent and reliable accessibility. Upping the odds with redundancy will help dull the edge of my "access anxiety", though logically, it can never relieve it. Will look into
Carbon Copy Cloner.

Time Machine back-up drive

Hi there! I have to change my Time Machine back-up unit with another one.
Can anyone help? I have a partition on the first external hard drive, and I cannot change it.
Is there a way to transfer the content of my "old" hard drive used for Time Machine on a new back-up unit?
