Mac Pro :: Unable To Know Raid 0/backup?
Apr 14, 2009
I have an 2008 2.8 octo with the stock 320gb WD drive. I use an external 1tb Seagate FreeAgent to backup. I use Super Duper to backup a bootable clone. I am interested in both more storage space and faster response.
1. If I were to get another of these WD 320gb units and make a striped raid using disk utility, I would get a 640gb volume, correct?
2. Could I back up the 2 drive raid volume to my external drive just like I do now?
3. Could I restore to either a striped raid or a single drive off the backups on my external in the event that after a hardware failure I decided either to replace the bad drive or just go back to using a single drive?
4. Would a two drive raid comprised of two 8mb cache WD 320gb units perform as well or better than using just a single Samsung Spinpoint drive, which is the other option I have considered?
The WD unit is $49 shipped, and a 500gb spinpoint is $59 shipped, so cost is about the same.
I just want to get the most bang for the buck out of my brokedick $50 storage upgrade, and I also want to be sure that I have a little piece of mind with my external drive backups.

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?

I am thinking about buying a HD for a full system backup and all files. I am worried about getting such a big HD and having it fail, thus loosing years of data. Is there any redundancy in a 1TB drive does partitioning help? What if the entire drive fails or are there multiple drives in those external hd? I need a reliable backup system for music, photos of child, that will last years. I want to be able to use the HD with both formats, pc and mac...what should I format with or is that a good idea?

Ive heard conflicing statments that the raid is software/hardware. anyone know for sure what it is (Im not talking about that card you can buy).
If it is software raid does this take a toll on the processors? is it serious or does it not matter at all.
IF it does matter. should I buy a exteran raid card? is there a mac compatible one. I just need basic raid0.
I just bought 2 samsung spinpoint F1 750s in anticipation of my new mac. But just want to make sure that raid is a wise decision.
for those who are thinking about replying about the dangers of raid. I know. I have time machine. if the raid goes down then so be it. such is life. I will have backups.

OK I do some Video Editing and Motion Graphics with FCP and Adobe After Effects.
I have a Mac Pro 2009 with 4 1TB Drives and 2 1TB Lacie Fire Wire 800 Drives.
This is the setup i have
1st Drive Mac OSX
2nd Drive is Windows 7 OS
3rd & 4th Striped and Mirrored to the 2 Lacies External Drives that are Striped. (raid 1 + 0)
My first question: is this a bad system? should i set it up a different way?
Second: is If a Drive goes out in the Raid 1+0 how will i know and how can i put a new drive in to fix it? How does this work?
Third: I set the RAID up with disk utility, is this ok, bad or good?
Fourth: IF the the OS Drive goes out will and i replace it and format it, will the RAID 1+0 Still be there? some where i read that its OS dependant?

I have a 1TB disk. It is now almost full. I just got a new 1TB disk and I want to make a mirrored RAID set of the two. If I create a RAID set in Disk Utility, does that erase my first disk? Or does it just mirror everything to the second?

If I needed to mount two drives in the empty optical bay and put both of them on RAID 0, would this and this be the only 2 things I would need?
Also, with the Pro Caddy 2, would I need one of their PCIe cards? Their site says that a card is needed, but since I would be getting the RAID card, would I need to even get one of theirs or would the RAID card be all I need?
They give three options for PCIe cards with the Pro Caddy 2: none, nonbootable PCIe card, and bootable card.
So would I be good with just the areca 1210 and the Pro Caddy 2 without a card or would I need a separate card for the caddy?

My MBP is 5,1, at last few months I use 2 HDD in raid 0, it fine and smooth, but after I upgrade 2*SSD ( OCZSSD2-2VTXE60G ) the nightmare is coming, only see one SSD (in org hdd bay), the optical bay never see, at first time I thought may be SSD is dead, so try to replace them, both SSD is work, second thought is optical bay dead, so put the hdd back, it work.
I don't what's going wrong, I just thought optical is not fit OCZ, may I know who is using OCZ in raid 0 please kindly tell me which optical you using.

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?

I have a 1tb external for time machine back up and have about 750 gb of stuff to back up. I was under the impression that when time machine backs up my stuff it will automatically delete the oldest backup to create room for the newer backup.
My problem is that i did a back up a couple weeks ago and then today i go to back up and it tells me back up failed only 718gb available for 740gb of stuff to back up
anyone have this problem? how can i fix it?

i would like to reserve my 4th bay for windows only drive and a software raid will be used for these.
what would you think is a better set-up,
3x internal drives (all of the same model, probably WD 640's) set in raid 0 (both serve as boot drive and scratch disk) occupying bays 1, 2, and 3. In this set-up, everything (DVD's, music, photos, final cut media) would be stored on this array.

I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.

I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)
My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.

I have a Lacie ext hard drive with 2 x 250gb HD that were one RAIDed into a single 500gb HD. I ran this update Lacie firmware update: http://www.lacie.com/support/drivers...r.htm?id=10053 And now my HD will only show up as two separate HDs of 250gb instead of a single RAID HD of 500gb.

I have a macpro with 4 x 1tb drives
Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?
Lastly, are the highpoint 3500 series a decent card? and fully compatible?

I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.

ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:
How fast is a Sata connection straight from HD>Motherboard... ~75mb/s?
Is the Raid 5 config with all those drives much faster... around ~110mb/s?
Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...
And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc

I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?

I am planning on getting a 2010 MP when they come and have a question about it. I am 90% sure that with my budget, I will not be able to after a RAID card. I am wondering if software RAID would be alright or if it's so bad it's not worth doing. Also, there is small chance that I could buy a RAID card later on, how would I install it? I will be using it for 3D animation with Maya and some zbrush modeling. Also I will be doing some Photoshop and illustrator and maybe some gaming on win 7 boot camp. Feel free to list any other pros and cons about either a software RAID or hardware RAID, I wana make sure I have all the details before making a final decision on it.

I'm looking for an app that will allow me to specify which folders I want to copy to my external drive, updating existing files within it and copying new ones.
I don't want to backup settings, my whole harddrive nor make a bootable backup. Just something to backup what I want to backup and where.
Not sure if Time Machine can do that, but it wants me to reformat my external before I can even find out..and considering how much is on there, I really don't want to have to remove that all elsewhere while doing so. [Don't think I could anyway, none of my internal drives have that much space.]
So, does anyone know of a relatively painless backup app that could do simply what I want? Doesn't sound all that complicated in comparison to some of the more convoluted backup apps I keep finding.

I have never setup RAID before and this question may be totally stupid for that matter.
Can I setup RAID 1 (or call it mirroring) without the RAID card? I have two 1TB internal drives in my Mac Pro and I want to mirror them. I don't want to spend another 700 bucks just to setup a mirror.
Disk Utility shows some RAID options, but I am not sure how to use them, or if they will work at all without the RAID card.

On my 2009 Mac Pro, OS X's disk utility seems to allow the provision of making a mirror RAID or a stripe RAID.
Is it possible to shove in 2 drives, make a RAID 0 for two of them, and then add in 2 more drives to make a RAID 1 out of that RAID 0? (a RAID 0+1?)

I have been the proud owner of a Macbook Pro 2.5Ghz with 4GB RAM, running Leopard 10.5.6 for just under a year and I have never been able to get Time Machine to backup my files properly. Instead I have been backing up my really important files manually to an external NAS drive.
However, I would like to back up all files to an external USB drive using Time Machine. I have a Freecom USB2 drive which I purposely bought, but when I try to perform the initial back up I get a message telling me there isn't enough space.
My MacBook has a 250Gb HDD and my USB drive is 500Gb (465Gb available), so I have no idea why I am getting this message. I have ensured that no other devices are connected in case it was also trying to back up those (USB & NAS drive), but still get the same message. It says I need 698Gb of space to perform the full backup - where is it getting this from?!
Within the options it shows me a panel containing an entry 'Time Machine Backups' with a size of 154.4Mb, which I'm guessing is the directory that I am trying to save the backups to.
I'm probably doing something obviously stupid but would appreciate it if somebody could point it out for me.
