OS X V10.7 Lion :: Time Machine Can't Find Drive Connected To Other Networked Mac
Feb 5, 2012
I have a Drobo external drive array connected by firewire to my primary home computer - a Mac Pro. the last year I've backed up two Macbook Pros (mine and my wife's) to this Drobo using Time Machine (The Mac Pro is always on and the laptops backup through the home network, through the Map Pro, to the Drobo). I recently did a fresh reinstall of Lion to all 3 computers. Now for some reason Time Machine can't kick the backup off. It gives me a "Can't backup - the backup drive us not available," or something like that.
A couple of key points:
* Through the primary computer, I have opened read/write file sharing permissions for all drives, including the FW connected Drobo
* From the laptops, I can see and read/write to the Drobo through Finder
* Through Time Machine preferences, I can select the Drobo as a backup destination - it's only when I kick off the backup that I run into the error.
* If I create a test admin account to try, I get the same problem when trying to back up.
* As a safegard, I have run a manual backup successfully to a separate external drive (mobile g-drive)

I have an alienware desktop with 1TB RAID 0 for general purposes and a new-generation 13" Macbook Pro (4GB/GeForce 320M/250GB). Anyways I provided this information to help with a question. Can I create a shared folder on my Desktop and set Time Machine to back up to it over the network?

I am not too tech savvy....Am I supposed to keep the external HD plugged in 24/7 in order for Time Machine to work? Is it going to damage the HD if it's constantly being plugged in?

I am in need of assistance with backing up my macbook pro using time machine. I am running Mac OS X leopard 10.5.8. I have attempted to backup to a network share folder on a Windows machine, but the backup abruptly ends. So, I decided to attach an NTFS external drive, connected via usb. The external drive was formatted on a Windows 7 machine (not quick format); so, it currently has no space occupied. I installed MacFuse and NTFS-3G. Then, I rebooted and attached the NTFS external drive. I set the preferences in time machine to backup to the aforementioned drive. However, Console is reporting that the backup failed with error 19, and time machine is reporting that the storage location for backups cannot be found, when i command time machine to backup now.
Is there something I'm missing? I have seen at least one other thread on the Internet where a mac user was able to get time machine to work with an NTFS external hard drive. Do I need to create a separate sparse bundle image and copy it to the external drive, similar to the method used to get time machine to copy to network shares on Windows? If the ironclad rule is time machine ONLY recognizes HFS+ drives, then a sparse bundle image is a good workaround. But then what is the point of MacFUSE and NTFS-3G. What is its purpose, as it relates to time machine?

Basically what I wanna know is: Can I configure time machine to back up to a hard disk that is connected to my router? I guess essentially I'm trying to make a homemade time capsule. Is this possible and if so, how?

I'm trying to backup the contents of my MacBook Pro wirelessly to an external hard drive that is connected to a Mac Mini in my living room. All the tutorials I've read say to create a sparsebundle file with the same name as the one that's found in the folder of your Time Machine backup.

I use a TC for wireless backup at home. When I return home after being away, Time Machine usually finds the TC and resumes its routine. Now this doesn't work any more. Even though the TC appears in the sidebar and is recognized by Airport Utility, when I select "Back Up Now" I get a message saying "the backup disk couldn't be found". I recently updated the OS to 10.7.4.

I would like to use FileVault to encrypt both my hard drive and time machine back up external drive. Does encryption noticeable slow down the computer.

I'm using a my book western digital nas drive for my time machine backups and time machine has been stuck on indexing for days. I saw some solutions in other threads, however on the my book the backup partition of the drive is private, locked, or hidden? and I have no idea how to get into that area of the drive if I was going to apply any of the solution I have previously seen...

I have a 1 TB drive in in my iMac that was recently replaced. The restored data uses about 850GB. I have been using a 2TB drive as a Time Machine backup drive. With the new internal drive in the iMac, TM said that it couldn't back up the drive, that 4.91TB were needed, and only 2TB available. I reformated the TM drive and I get the same error message. How can a 1TB no longer be backed up on 2TB?

I had been using Time Machine successfully for a while now but I am going traveling and thought I better encrypt my backup just in case it get's lost or stolen. I turned on encryption and chose a password, I don't really know if it completed the process as I was away from my computer, I susepct it failed, what I do know is every-time I plug the drive in I get the popup FileVault window and once I put my password in and select unlock it just goes grey, it's not saying it's incorrect just nothing happens and the drive does not mount.Â
I can see the drive in Disk Utility but if I select it I get the spinning beach-ball. I'm afraid encryption has destroyed my new 2TB drive (less than a month old). I don't really want to attempt to erase the drive as it contains other data that is not back of the Time Machine backup. I'm running 10.7.4. What can I do to get the drive mounted?

I was trying to set up my Time Machine to an external hard drive. I didn't continue because it asked to "initialize" the hard drive which I had a lot of important things on.
I have another external hard drive I'd like to use but, my Time Machine has this error code of -43. What is this and how can I use my Time Machine on another external hard drive?

12 Months ago I bought an external hard drive WD My Book. After I download Yosemite, successfully, I have been getting messages that that my Time Machine was not backing up.  When I open Time Machine I get a message Time Machine disc not connected. Also the Oldest Backup 28th Sept October 2013 - Latest Backup 28th October 2014. I have checked My Book and that is working OK. What is happening with Time Machine.Â

I've just replaced an old MacBook Pro with a new one and used Time Machine to get the new MBP set up. All is well and it looks like my new computer is a mirror of the old (tested for a week now). If I turn on Time Machine with the new MBP using the same hardrive as the former, will the files remain and be accessible? Presently, I can only access the old files by going into the hard drive through Finder and even then, most are locked.Â

Tried unlocking and allowing myself to read and write. Nope. Tried holding down the option key. Nope.
This drive is no longer being used by time machine and I want to delete some files on it. Is there a way to do it without wiping the entire drive?

Time Machine is not working correctly since installing Lion. I found (from using Adobe Bridge) that there seem to be automatic back ups being made 20 times a day and onto my hard drive! Usually I back up to an external drive specifically for back up using Time Machine. Now time machine takes several hours to back up when I have that disk wired in (with USB) and the Time Machine icon in the Apple menu is always showing that the back up is delayed. Â

I used my external hard drive to store important documents off of my previous Mac. None of these documents are on my new Mac. Will I lose these docs if Time Machine backs up to this external hard drive? Will Time Machine save over those docs?

I am trying to get Time Machine to backup my external hard drive. I have the external drive formated as Mac OS Extended (journaled) and I have also removed the drive from the Excluded list.I put some 'test' files on the external drive and told TM to do a backup and when it is finished the only way I can see my external hard drive in TM is if it is connected to the computer. It doesn't seem to be backed up anywhere in TM that I can see.

Is there a way or a utility to sync a Time Machine backup with the source drive?
I mean, so that all files which no longer exist on the source drive would be removed from the Time Machne backup too?

I have a 500 GB external drive that uses FireWire. Recently Time Machine started deleting several backups to make room for new ones. It now says the oldest backup is May 4th, 2012. I thought this sounded like a problem. When I looked into the details, my iMac now thinks my hard drive has 400GB instead of 500GB.Â

I have a Windows LAN to connect to a USB backup drive. I cannot find out how to set up Time Machine to connect to the USB backup drive. Does Time Machine only work with Airport devices? If not, then how do I set up Time Machine to see my USB drive on the network?

Mac Mini running 10.8.5. Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications. TM does back up the internal HD.

I was using an external drive for Time Machine for the past year and a few months On Saturday a message came up that it failed. I tried initiating the Time Machine again but failed. I decided to get a new bigger external drive to use for Time Machine. When trying to eject the external drive I was using it gives me this message:
Would it be safe just to force eject or log out and then log back in again to eject it so I can use my new external drive?
