OS X :: Unable To Backup Time Machine On LaCie External Drive?

Aug 2, 2009

Time machine is having problems backing up to my La Cie drive. It will start and then show the progress, but it stalls at a very low #(256 kb, for example).

Left it to do its stuff overnight and it never budged. Pulled this off of the console (after reading some other posts). Not sure if this is associated w/the problem, though.

8/2/09 10:28:45 AM mds[34] (Error) Import: importer:0x872000 Importer start failed for 89 (kr:268435459 (ipc/send) invalid destination port)

This error was reported pretty much every 4 seconds.

I erased and reformatted (mac os extended, journaled) the La Cie but that did not seem to work.

OS X :: Unable To Backup With Time Machine / External Volume Cannot Be Mounted

Mar 14, 2009

I'm having trouble backing up with Time Machine. Here's the setup:

1. Three, 1TB external hard drives in a concatenated software RAID. This means that they are treated as one large drive. There is no mirroring, no increased data rate, blah blah blah. It's just three hard drives in the place of one. I am aware that this means my backup is three times as likely to fail with the hardware, but that's OK.

2. These three are connected to a USB hub.

3. This hub is connected to a G5 tower. The G5 tower can back up to the concatenated drives (I'll call them just a RAID from here on), and also all additional external hard drives that I connect to the G5 tower have been backing up to the RAID no problem. This is great.

Here's the problem:

I'm trying to get two more computers to back up to the RAID wirelessly. I read a lot online about how this didn't used to be a supported feature (backing up to an external hard drive over a network with time machine), but that Apple has recently upgraded Time Machine to support this functionality.

The first computer I started with to try to backup over the network was a Macbook Pro, trying to get it to backup to this RAID. It can see the RAID over the network, mount it, copy files to it/read it, but CANNOT time machine backup to it. I select the network RAID as the backup device, hit "back up now," then get this message:

"The external volume cannot be mounted."

This is really bizzare, considering that it is mounted, and that I can copy to it. Just for your information, I have an airport extreme wireless network that has been working beautifully, no Keychain access issues, no 3rd party firewall, nothing. I've run through Applecare on this issue: the MacBook Pro has never done ANY time machine backup on the RAID, not even a partial one, so there's no dangling sparse bundle or backup folder or anything like that. All network permissions check out, etc. I've tried repairing the RAID with disk utility, as well as repairing permissions (although I have not done either of these things to the MacBookPro).

The latest thing I tried was plugging the RAID directly into the Macbook Pro. Here's where I got the first clue (at least I think so)...Plugged DIRECTLY into the MacBook Pro, the RAID will mount, but the MacBook Pro WILL NOT backup to the RAID. It gives me the same message: the selected volume cannot be mounted. Again, this is strange considering that, just like when I am viewing the RAID over the network, plugged directly into the MacBook Pro the RAID will mount, I can read it, copy files to it, etc.

I have considered plugging the RAID into the Airport extreme directly, but first of all this would mean much slower transfer speeds with the G5 tower, which is a big issue considering the files I am backing up every day, and two, since it seems that the RAID won't be recognized by the MacBook Pro even when plugged in directly, I'm thinking that this is a more fundamental issue.

Hardware :: Can Time Machine Backup External Drive Attached To Time Capsule?

Mar 11, 2009

I have an external 500gb drive plugged into my brand new Time Capsule. The 500gb drive basically stores my entire library of music and my iTunes points to this external drive.

Is it possible to have time machine backup all information on the 500gb drive to the time capsule, so encase the external drive takes a dump, I don't loose my entire music library? Maybe time machine is already doing this, I am not sure.

OS X :: Time Machine Backup Of External Drive?

Nov 30, 2008

I have a 320GB internal drive and 1TB (MyBook) external drive. I recently bought a second 1TB external drive (MyVault)to use with Time Machine. I have removed the exclusion of MyBook so that Time Machine backs it up but so far it has refused to do so. It is happily backing up the internal drive. I have looked in the Mac OSX Leopard Missing Manual but still have no clue as to what I am missing. The initial setup (and backup) did not include MyBook until I discovered that I would have to remove it from the exclusions.

OS X :: How To Use External Drive To Backup Time Machine HD

Mar 15, 2009

So I've run into a Mac issue I'm not sure how to handle. I've got a Mac Pro running Leopard. I've got 3 internal Harddrives: 1.) 250 GB (runs my OS and applications), 2.) 500 GB (where I store all my source files for my business), 3.) 750 GB (serves as the backup for Time Machine for all the files on Harddrives 1 and 2.). So I began thinking the other day. What would happen if somehow all 3 harddrives were destroyed (theft, fire, power surge, flood damage, etc.)? I would lose years worth of source files from my business (graphic and web design files mostly).

So I went and bought a 1 TB external drive today. Ideally I would like to put the external drive in another location and bring it out maybe once a week to backup the 3rd harddrive from above (the one being used for Time Machine). Does anyone have any suggestions on how to backup this harddrive...some type of program that essentially acts like Time Machine? I just basically need it to mirror my Time Machine Harddrive. I found a program named Super Duper (http://www.macupdate.com/info.php/id/13803/superduper) not sure if anyone has had experience with it or not. I'm open to any suggestions on how to use the external harddrive to back up my Time Machine harddrive.

I was thinking of getting an external hard drive for use with Time Machine. On Amazon I found a Seagate 1.5 TB unit for $129. However there is a similar model "for the mac" for $192. I am wondering if the cheaper unit would work, or if the one for 50% has some indispensable feature.

OS X :: Unable To Write To NTSF Drive After Time Machine Backup

Jan 7, 2011

I've purchased a 2TB external drive, I downloaded and installed macfuse and ntfs-3g AND tuxera ntfs and I formatted the drive to ntfs. Everything was working perfectly (reading and writing) until I unplugged the drive form my computer. So when I plugged the drive back in, it could only read and no longer can write information.

What is going on? I didn't even turn off my computer, the only thing I did was backup my computer with time machine (onto a separate drive not the NTFS one) and plug the new drive back in. I've reinstalled all 3 programs and restarted my computer but nothing seems to be working.

First, the drive kept triggering a "your external device may have been disconnected improperly" message. That despite repeated erasing of the disc and restarting of the set up a Time Machine backup usinig this 500GB USB2 drive with its own power supply. Finally, I placed the drive on its fronot panel and it stopped disconnecting. Then, it started the backup. It is now 9:30 in the morning. I started this backup at 9:30 last night. so far it has managed to accomplish 23.79 GB of a 64.45 GB back up.

Hardware :: Unable To Verify / Repair Time Machine Backup Drive?

Aug 24, 2008

Yesterday I noticed that my computer had been trying to complete a backup for quite awhile... Well it turns out that it was only a 382KB backup and it was taking hours. I tried clicking "Stop backing up" and nothing happened. The drive was in a repetitious clicking rhythm, and when I tried to eject it, Finder said it was in use. I put my 10.5.2 install disk in and ran Disk Utility. I have two partitions on that drive, Beta and Charlie. Beta verified and repaired without a glitch, but my time machine partition, Charlie, said "Invalid node structure, volume check failed." Also, disk utility was unable to calculate how much space remained on that partition.

MacBook :: External Display Imac As A Backup Drive For Time Machine

May 22, 2012

I just got a new MacBook Pro for graduation. I've decided to use my iMac as an external display and use my Macbook Pro as my main computer. My iMac has about 1TB of space while my MacBook has about 500 GB. Since I'll be using my iMac primarily as a external display I was thinking about also using it as an external harddrive so I can backup my data from my Macbook via Time Machine.Is this ok to do? Does anyone advised that I don't? I just want to make sure I don't screw up anything before doing so. BTW I also have a WD external harddrive connected to my iMac.

OS X :: Unable To Backup With Time Machine / Snow Leopard Cannot Locate Network Drive

Apr 20, 2010

So I have a 15" MBP running Snow Leopard and have recently installed a Western Digital MyBook 1TB World Edition on the network to serve as my Time Machine backup drive. Most of the time, it works flawlessly and OSX / Time Machine does its thing and backs up.

Every once in a while, Time Machine says backup has been delayed because it cannot locate the network drive. This when I can easily access the network drive from other machines on the network, and also from my MBP in Finder. It's just Time Machine that somehow fails to find that drive. When I enter Time Machine preferences and look for the drive, it brings it up immediately and asks me for the username and pwd and viola ... it's up and running again.

OS X :: Time Machine Cannot See External Airport AEBS Drive - Need Incremental Backup Solution?

Jul 13, 2009

I have a Mac Book Pro. Due to the total amount of files and data, I keep my media files on an external drive connected via USB to my Airport AEBS. Of course, I connect wirelessly to the AEBS.I use Time Machine to back up my computer onto an second external drive also connected to my AEBS in the same fashion.However, TM does not allow me to choose the files or folders from the external AEBS drive containing all of my media files to also incrementally back them up using Time Machine. It should. I wish it would. Why won't it? Can I make it work that way? If so, how? TM is the best incremental backup program I've seen. I really want to back up my media that way. But I don't want to tether my laptop by connecting an external drive directly to it, and I don't have the space to store my media files directly on my laptop.

Hardware :: External Hard Drive - Time Machine Backup - Ended Up Freezing My Mac

Sep 7, 2009

Recently this external hard drive I have spun down right in the middle of a Time Machine backup. It ended up freezing my Mac for a second so I turned it off only to have it come up saying it was corrupt and needed a format. I did that and it seemed to work fine only to see it would never eject (it had nothing on it but it claimed programs were using it) so I was forced again to shut it off without ejecting.

This time I turned it back on and it didn't (and still doesn't) appear for about 15 mins.. now SL says "Can't be read" and when I go to disk utility it just shows the drive (no volumes, everything like partioning and erasing is all greyed out)

OS X V10.6 Snow Leopard :: External Drive Mounts But Not Recognized As Time-machine Backup

May 30, 2012

I have a MBP 13" 2009, and had a HDD fail yesterday. I have an external HDD for backups with timemachine (WD 1Tb), with daily backups.I bought a new internal hdd, plugged it in today, and when presented with the install options, I selected recover from backup. There, my drive appears (in yellow), but when pressing continue, I get a message: No system backups found.

I looked around on forums and people suggested that a normal installation should be done followed by migration assistant. When I try using migration assistant and select Time Machine backup, the next page just shows up empty with a rotating thing in the middle.

When I browse the Backups.backupdb folder, everything is there, including my last backup from Saturday. I see that I can recover my files, which obviously is the most important bit, but I would like to restore Applications, settings etc, as to not waste too much time.

Software :: Time Machine Unable To Perform Backup / Backup Is Too Large For Backup Volume

I am getting the following error from Time Machine when doing my first backup. The startup disk being backed up, and the TM disk are both the same size.

Macintosh HD: 465.44 (total); 393.99 (free); 71.45 (free)
Time Machine: 465.44 (total); 465.29 (free)

The Time Machine error is: Quote:

"This backup is too large for the backup volume. The backup requires 472.7 GB but only 465.3 GB are available." why would this be? Other disks are excluded from the backup, and Time Machine is telling me that it needs more space than it actually needs. What should I do?

Software :: Unable To Backup Via Time Machine / Backup Disk Image Could Not Be Created

May 1, 2008

I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.

So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.

It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.

However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.

More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. (http://www.macosxhints.com/article.php?story=20080420211034137) Have not tried this yet as I thought it would be prudent to seek some help first.

Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):

Is this because time machine requires a network faster than 802.11g?

Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?

I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?
