OS X V10.7 Lion :: Time Machine Backup Of RAID1 Data Volume(s)?

Jun 19, 2012

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.

OS X :: Unable To Backup Data Via Time Machine / Volume Cannot Be Mounted

Jan 1, 2009

I've spent a good deal of time over three days trying to do something that I think is both doable and shouldn't be all that hard. I have a 750gb external HD attached to a Mini, and I'd like to use that drive to do TM backups for the Mini, as well as three MacBooks.

But I can't seem to get access to the backup drive from the laptops to either get going in the first place, or to remain available for TM. I get "volume can't be mounted" errors, "image can't be mounted errors", etc. I find that I can't ever eject the backup drive from the Mini (always told an application is using it...even if I've just booted up the Mini). And with one of the MacBooks, even a direct FW connection to the drive doesn't result in the drive showing up in Finder.

Isn't this a pretty straightforward thing to do? Is there a step by step somewhere that might help me figure out what I'm doing wrong, or what I need to fix? Should I reformat the drive again and start over (there are no important backups on it yet)? By the way, the drive is formatted Mac OS Extended (Journaled).

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

Oct 26, 2008

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?

OS X :: Time Machine Not Working / Backup Is Too Large For The Backup Volume

May 23, 2009

Well TM is acting up. I get an error that reads: "This backup is too large for the backup volume."

Both the internal boot disk and the external baclup drive are 1TB. The internal one has a two partitions, the OSX one that is 900GBs and a 32GB NTFS one for Boot Camp. The external drive is a single OSX Extended part. that is 932GBs.

Both the Time Machine disk, and the Boot Camp disk are excluded from the backup along with a "Crap" folder for temporary large files.

Time Machine says it needs 938GBs to backup only the OSX disk, which has 806GBs in use with the rest free. WTFFF?

This happened after moving a large folder (128GB in total) from the root of the OSX disk over to my Home Folder.

I have reformated the Time Machine drive and have no backups at all of my data and it refuses to backup!!

Why would it need 938GBs of space to backup if the disk has "only" 806 GBs in use??? Is there anyway to reset Time Machine completely???

OS X :: Time Machine Error - Backup Volume Is Read Only?

Nov 15, 2007

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.

Applications :: Time Machine Cannot Find Backup Volume?

Feb 20, 2009

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.

OS X :: Move Existing Time Machine Backup To New Volume

Mar 4, 2009

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.

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.

OS X :: Time Machine Backup - Data Increased

Feb 11, 2009

After a catastrophic HD crash I bought a small 250GB external hard-drive an started to use Time machine. Since my Mac was freshly formatted, I tend to keep it tidy and clean and keep good track of what comes in. I noticed my time machine backing up 15 GB of data which allegedly would have been added within two days. I could absolutely not trace this on my computer nor when I compared current folder contents with the most recent backup. Downloads, Apps., System are all excluded from my time-machine and couldn't represent such a dramatic data increase on my separate HD.

OS X :: Does Time Machine Verify Backup Data?

Oct 6, 2009

I'm doing an initial backup to a Time Capsule and I want to make sure all my data was copied successfully. Does Time Machine verify that the data was copied successfully or does it just send it and hope everything copied alright? I know this is the kind of question only the Apple developers would know for certain, but hey, sometimes folks on these forums are surprisingly knowledgeable so I figured I'd ask here.

OS X :: Data Transfer - Using Time Machine As Backup Tool

Mar 13, 2009

I'm getting a new macbook. Currently I use time machine as a backup tool and was wondering if I should use it to transfer all my data to the new mac. One benefit of a new harddrive is the fresh install without all the junk that has built up over the years right? So wouldn't time machine just be transferring all the junk and stuff I want to the new mac? or is time machine smarter than this.

OS X :: Backup Data Using Time Machine / Saving Old Backups?

Oct 7, 2010

So I just successfully migrated all of my data and settings from my old iMac to my new 27 inch iMac using the Time machine backup on my Western Digital 1 TB external hard drive. Aside from the Time machine backup folder I also dragged a few other things over to the external hard drive because there was so much extra space on it. The drive is not partitioned.

So I'd like to start using Time machine with this new 27 inch iMac but the empty space that's left on the external hard drive is barely large enough to cover what I now have on the internal hard drive on my new 27 inch iMac. If I were to remove the Time machine backup from my old iMac there would be plenty of space again unless starting Time Machine on this new 27 inch iMac will just copy right over that backup file? Everything on this new iMac, the data and settings and so forth, is exactly the same. So is the user account. However the previous Mac was running Leopard while this new iMac is running Snow Leopard.

So if it doesn't copy over the old backup it will just create a new backup file? And if it does create a new backup file is there any point to keeping the old backup file since I no longer have the old iMac and wouldn't be able to access it again? Obviously if I didn't have to keep it I could erase it which would create plenty of extra space for me to start using Time machine again but with this new iMac.

OS X :: Time Machine Backup Quicken Data Files Also?

Dec 6, 2010

We are a PC to Mac convert and still trying to understand some basics. We have an iMac 21.5 and expecting delivery of a external 1.5 TD drive. More than we'll even need, but dirt cheap. We also run Windows 7 64 bit through VMware Fusion. The only reason for that is the Windows version of Quicken is a better product the the Mac version.

We will back up pics, Videos, etc., on the iMac under MacOs with Time Machine. Can Time Machine also backup the quicken data files from the Windows 7 VM machine? I hoping we do not need to maintain separate backup drives to manage the different type of file formats between Windows and Mac. I hoping this can be managed through one place...Time Machine.

OS X :: How To Retrieve Data Accidentally Overwritten By A Time Machine Backup

Apr 14, 2009

I connected my windows removable disk to my colleague's mac to transfer some data. Accidentally her system started a time machine backup on my removable disk. Although we stopped it during middle of the process, now my disk is no longer recognizable in windows and all I can see under a mac system is her backup file.

The process took a very short time. I wonder if it has deleted everything. Is there any chance I can get the overwritten data back? They are very important to me.

Besides, is it a common problem of time machine backup? It is too dangerous for the removable disks.

Applications :: How Long Would Full Backup Of 900GB Of Data Take Using Time Machine

May 12, 2010

How long would it take to backup 900GB of data doing a full back-up using TimeMachine and my MacBook? My MacBook being a 2009 model with 2.13 GHz Intel Core 2 Duo and 4GB 800 MHz DDR2 SDRAM.

I have:
1 x MacBook 160GB drive
1 x Imoega minimax 500GB drive (firewire or USB 2 connection possible)
1 x Seagate 320GB drive (USB 2 only connection)

I have a 400 firewire port in my MacBook in addition to 2 USB sockets, as well as fireWire hub with power supply, should I wish to run 2 or more firewire devices at once, into the 400 firewire port.

My current backup drive is a Samsung USB2 1TB drive but for reasons that will hopefully become obvious below, I will need to purchase a new drive. I think a 1.5TB or 2TB would be fine and I guess a 400 firewire port is still better than USB2, even though it's only 400. However I'm not sure about the time issue.................

OS X V10.5 Leopard :: Time Machine: "Backup Volume Could Not Be Found."

Feb 15, 2012

I saw that this issue has been addressed and there seems to be a few solutions for it but I had a hard time understanding some of the steps described in previous posts. I am running OS Leopard 10.5.8 and I am using a FreeAgent 500GB hard drive for Time Machine. Today I tried to back up and all of a sudden I'm getting the "Backup Volume Could Not be found" error. I tried deselecting it and reselecting it, and now its saying it doesn't have enough space to back it up. 

I really don't want to completely erase the hard drive if that isn't going to fix it. Before now it would just overwrite a few old backups and make enough room for a new one, while leaving 2 old ones on there. I want it to do that.

OS X V10.7 Lion :: Time Machine Backup Is Too Large For The Backup Disk?

Feb 10, 2012

my TM wil not back up! It states that this backup is too large for the backup disk. The back up disk requires 573.50 GB but only 225.23 GB are available. The TM needs work space on the backup disk, in addition to the space required to store backups. Upen TM perferences to select a LARGER backup disk or make the backup smaller by excluding file. 

Okay I;m sorry but obvioulsy I dont get this. I've never called Apple for help! I have every product they sell practically including Protection Plans I never used and no one will help me with this. My MAC is starting to have black or white screens and i can hear it running but it will not do anything so i have to reboot it, it screws up Enturage and then I have to rebuild that ( 5 times this year) anyway... I would like to back everything up- can I delete everything on the Time Capsule or Time Machine; god I dont even know what it is called Im so MAD... help if you can please. I'm going to have to take this to the genius people at the store and probably buy another computer but like before they will not save my files.
