What means: Promise Pegasus compatible with Time Machine RAID-support

On the (Dutch) Apple shop it is stated at the Promise Pegasus page: the Promise Pegasus is compatible with Time Machine RAID-support.
What does this mean? What is then the "physical connection path" between the TC and the Thunderbolt Pegasus RAID system?

Thanks for responding to my question. I guess I'm not sure I understand your reply though. I had no problem installing OS X on the 3TB WD Caviar Green and WD assured me that if I wanted to install only Windows 7 on it, there would be no compatibility issues. The problem lies with wanting the drive to be dual-bootable I guess via using Boot Camp (I know of no other way to go about it). The tech at OWC (where I bought the drive) said he had never heard of any problems with being able to install both Mac and Windows OS on the drive. In fact, he gave the same reply as yours: most hard drives should be able to work perfectly fine with your Mac. It's just that I can't get XP or Windows 7 (32 bit or 64 bit) to install on the 2nd partition, making the drive I have now not dual-bootable. The tech said 2TB hard drives were different and should solve the problem but when I asked him for any discernible spec I could look for in shopping for a replacement drive, he couldn't give me one, i.e. most drives should be okay. I have paid to have the 3TB installed and will have to pay to get the drive taken out and a replacement put back in -- I want to make sure whatever drive I put in this time allows me to have 2 partitions: one for my Mac OSX system and the other for my Windows enviroment (either XP or Windows 7).
If there is a work-around not involving Boot Camp, please let me know. I thought the reason for using Boot Camp as opposed to Disk Utility to create the dual-bootable drive was the benefit of using Mac drivers on the Windows side.
If there is another way, I don't understand why PC world made this blanket statement:
"Mac users should know that WD's new drives do not support Boot Camp, therefore they cannot be used as a dual-boot hard drive."

Lacie USB 3.0 - do I have to erase it to be compatible with time machine?

Just bought a LaCie USb 3.0 external hardrive. Do I have to erase it to be compatible with time machine?

I would do this:
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
It's now ready for use on your Mac.
If for some reason Disk Utility will not repartition or format the drive it means the drive has been preformatted with NTFS to which OS X cannot write. You will need to repartition and format the drive using the MBR partition scheme and formatting FAT (MSDOS.) When you succeed with that, then open Disk Utility again and do the above process that now should work.

I needed a 2tb hard drive for my new iMac whats the best to work with time machine for around £100

Any suggestions about the best 2 tb hard drive to work with my imac,compatible with time machine for around £100

There is no such thing as "best" and "inexpensive", you either want one or the other but you cannot get both. IMHO I'd recommend OWC's Mercury Elite Pro (www.macsales.com) however because you are on the other side of the pond you may want to consider a Lacie product. High quality, not cheap but good stuff for the most part.

Which External Drives are compatible with Time Machine. I plan to utilize it for backups and to connect to an Airport Extreme.

MBP Retina, 15 inch, Late 2013. Intel Core i7. OSX 10.9.4
Which External Hard Drives are compatible with Time Machine.
I plan to use one drive for automatic backups connected to an Airport Extreme.
The connection can be USB or Ethernet and should be expandable.
OR
should I just buy the Time capsule and avoid the compatibility, connection and interference issues.
Thanks

Hi Kappy,
I just saw that on the Apple Support site that "Time Machine is not supported with USB hard drives that are connected to an AirPort Express or AirPort Extreme device", just as you have suggested.
Why is the newest model of the Airport Extreme, which is the model I have, an exception to the Time Machine compatibility?
The following information is from Apple website:
Time Machine works with:
AirPort Time Capsule's built-in hard drive (any model)
External USB hard drive connected to AirPort Time Capsule (any model)
An external hard drive connected to your Mac
Use the Time Machine pane of System Preferences to choose your backup disk(s).
Additional Information
Time Machine is not supported with USB hard drives that are connected to an AirPort Express or AirPort Extreme device.

Is FileVault 2 compatible with Time Machine?

Before taking the dive into whole-disk encryption, I just want to know:
How well does FileVault 2 integrate with Time Machine? Is it as smooth as I'm hoping, in that it will allow me access to my old backups and not create a huge, multi-day hassle as Time Machine again laboriously backs up my entire fixed disk?

As Neil says, it's unreliable and +*not supported by Apple.+*
If you have a desktop Mac, you can back up wirelessly to a shared drive connected to it.
See #2 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum), for supported destinations.

What's not backed up with Time Machine?

Can someone explain to me why the iPhoto library file on my computer is 7.29 GB and it's only 4.51 GB in the Time Machine backup? I'm using iLife 08.
I know that temporary files and cache files aren't copied by Time Machine, but does that mean that the iPhoto library file on my computer consists of 2.78 GB of temporary files?
When I compare the file size difference of the Pictures folder with the Music folder of the original files and the TM backup the difference in the Pictures folder is almost 3 GB, while it's only 1.6 GB of difference in the Music folder.
All suggestions are appreciated! I'd rather find out now than after a complete system restore!
And I've by the way, read this thread: http://discussions.apple.com/thread.jspa?messageID=8150270&#8150270.

I use BRU (tolisgroup.com) and run the backups of my users files and changed system files (ldap and OD files) to a desktop 1TB firewire drive. I use Carbon Copy Cloner or SuperDuper! to make complete bootable copies of the system drive onto a portable carrier 320G (my user directories are on a 4TB ISCI Drobo Pro).
There are a couple of other similar backup systems similar to BRU, but you are going to want something designed for a server. If you pay, the cost will be north of $100.00

Seagate drives not compatible with Time Machine causing OS lag/hangs?

Setup-
Intel iMac (Early 2006)
Mac OS X 10.5.1
Seagate FreeAgent Pro 750GB External Drive
Reproducible Issues
MacOS X lags at start up with the Seagate drive connected via Firewire and Time Machine enabled.
MacOS X hangs at shutdown with the Seagate drive connected via Firewire and Time Machine enabled. The only way to turn off the iMac is to hold the power button down.
I have contacted both Apple Support and Seagate Support. The outcome with Apple resulted in finding no issues with my iMac. The same can not be said of my 35 minute call with Seagate this morning.
The Seagate rep took me through basic troubleshooting steps and then proclaimed that it was Apple's issue and that Apple had issued a patch for this problem. However, the rep was unable to even provide the name of the patch. The problem with this declaration was the fact that it was based on disabling Time Machine and restarting the iMac once. On the second, fifth and seventh reboot after getting off the phone, the iMac hung on shutdown and lagged on reboot.
To add insult to injury the Seagate rep told me not to use the touch sensitive power button on the Seagate drive, since "it doesn't always work properly." Quoted word for word.
A co-worker of mine uses Time Machine with a LaCie drive on his PowerMac G5 and has had zero issues from day one. At this point in time I'm probably going to wipe the drive and return it to Costco unless someone can suggest an alternative.

Hmmm...bought at costco
I bet it is formated with the Master Boot Record Format. it will mount and OS X will read it, but Time Machine will not be able to use it.
You need to be in finder, under go menu, choose utilities. in folder that opens, double click disk utility. This will open a window that shows all your connected drives. Highlight the seagate drive ( the top choice, thats give the drives storage size). in the top group of buttons in the right side of the application window click the partition button. The Volume scheme will show current. Highlight this and choose 1. to the right of that is a place where you can name the drive. Use only normal letters and numbers here. On the bottom of that window, click the options button, and select GUID. click OK and give it a few minutes. close the disk utility application when it is finished
After it is formatted, the drive should show up on your desktop and Time machine should recognize it.

What external hard drives work best with time machine

What is the best external drive that is compatible with time machine?

I see a lot of people on the Apple Discussion boards mention Time Capsule. The experience I've heard from folks with the First gen units was terrible. Poorly designed, poorly manufactured (sorry Apple!). They suffered all kinds of heat stress failures etc. The follow up devices are supposed to better, but I don't think it's mandatory you buy Apple product to run Time Machine. In fact choose based on price/capacity, then possibly on Manufacturers reputation. I use a external USB dock that has a Serial ATA connector on it. That way I can swap drives out when/if they fail or get full. That way I KNOW who manufactured the actual drive itself. Often times if you get a Time Capsule the drive manufacturer is the "flavor of the month" so to speak. There's a number of outfits that make these bare SATA style docks, and you can connect them through USB (which I have) or higher speed connectors like FireWire 800 (for faster reads/writes/backups). My best recommendation is to buy one of those SATA dock devices, then buy a bare hard drive from a reputable manufacturer. Then setup Time Machine and use the left over space that it doesn't use for your growing iPhoto collection? Use your best judgement, as there's no real right/wrong way.

Does filevault encryption work with time machine?

Filevault under Snow Leopard would allow you to encrypt data on your Mac disk but was not compatible with Time Machine i.e. you could not back it up once encrypted or restore it.
Does anyone know if this has been addressed in Lion i.e. data encrypted in Filevault is capable of being backed up to a time capsule and is recoverable using Time Machine.
The release documentation does not make this clear, although a technician led me to believe it would be fixed in Lion.

According to my experience and to this -> http://support.apple.com/kb/HT1427, FileVault in Snow Leopard was compatible with Time Machine.
The thing was that, as FileVault encrypts your home folder as a disk image in 10.6, Time Machine was backing up that encrypted disk image. So
1. Time Machine could backup your home folder only when you were not logged in your user session and the computer was awake
2. with this system, you could not browse your home folder in the Time Machine incremental backups, but could only restore your complete home folder from that encrypted disk image.
In Lion, however, Filevault 2 encrypts your complete hard drive.
This means:
1. You can use Time Machine with FileVault 2 enabled in Lion (http://support.apple.com/kb/HT4811)
2. Recovery HD must be present on your computer's startup volume to use FileVault 2 (not an external Recovery HD) (http://support.apple.com/kb/HT4718)
I guess Time Machine, like it used to do with the user's home folder in 10.6, will backup your encrypted hard drive in Lion, but you will not have the ability to browse your Time Machine backup to find specific files / folders in the backup. But this backup can be used to restore your system. (http://support.apple.com/kb/HT4811)
(May someone correct me if I'm mistaken there ?)

What are the proper xattr in Time Machine folder hierarchy?

Hi there,
this is a highly technical question as I am trying to reconnect a corrupt Time Machine volume to its original Macs, one of them running SL, the other Yosemite.
I tried what Pondini advises on his website, including a migration of the network preferences. When first plugging the TM volume, I get this in the Console:
16/01/15 02:32:12    com.apple.backupd[38751]    Starting standard backup

16/01/15 02:33:24    com.apple.backupd[38751]    Backup failed with error: Not enough available disk space on the target volume.
I don't understand how it can detect a migration but still can't delete older backups on this drive to make room.

The MAC address in 3c belongs to the Snow Leopard Machine, the 00 one to the Yosemite machine. I know it sounds weird, but it is unclear how TM recognizes its backup drive. I first disabled ACL with fsaclctl (taken from a Leopard install DVD), and it worked, as said by:
sudo /Volumes/TW2/fsaclctl -p /Volumes/TW2
Access control lists are not supported or currently disabled on /Volumes/TW2.
Made sure the hidden file with the MAC address was correct, then re-enabled the ACLs.
ACLs and Xattr
Since the internal HDD had to be replaced, I wrote the com.apple.backupd.SnapshotVolumeUUID with the new HDD UUID in directory "Backups.backupdb/snowy/Latest":
Latest cubytus$ sudo xattr -w com.apple.backupd.SnapshotVolumeUUID 361B184E-E1FF-3860-95E2-XXXXXXXXXXAE "Macintosh HD"
Then went up two levels and checked the xattr:
Backups.backupdb cubytus$ ls -al@
total 0

Each computer has the correct addresses and HostUUID, i.e. the current ones.
Yet neither of those give the "Reuse existing backups" shown on Pondini's website, and tmutil on Yosemite doesn't succeed in reconnecting to the backups.
What is the point I am missing?

Hey 2cpd2,
I see that you need help with restoring your computer from a Time Machine backup. Here is an article for you that should be able to address this question for you:

Am replacing airport extreme with Time Machine and want to upgrade from Tiger to Snow leopard. Am told I should manually back up into T Machine before OS update but set up utility won't allow anything with OS below 10.5 and I'm 10.4.11. What to do?

I think you mean you are replacing your Airport Extreme with a Time Capsule. Time Machine is software integrated into OS X 10.5 & 10.6 used to automatically backup a system to an external HD. Time Capsule is an Airport Extreme that has a hard disk integrated into it that can be used for storage or as a Time Machine backup drive.
Because you are currently on Tiger 10.4.x you can backup to a external HD using SuperDuper or Carbon Copy Cloner. Having a backup is very wise before doing any major system update. After you have created the backup and have successfully upgraded to Snow Leopard you can still use the external HD for many things. The strategy I'd recommend is to use the new Time Capsule as your Time Machine backup and then use the external HD as backup using SuperDuper or CCC. Redundant backups is wise because backups can (and do) fail too! In addition both SD and CCC are bootable clones, this is useful in that if your internal HD crashes you can boot from a cloned drive and continue working until the internal HD is replaced.
Below are some links to some articles from MacWorld, I would recommend reading them where you find a common theme, redundant backups. Backup Plan I, Backup Plan II & Backup Plan III.

I have been using a WD Passport with Time Machine on my iMac. Since I upgraded to Mavericks, the backup no longer works. What do I need to do?
I assume that upgrading the WD SmartWare is irrelevant as it is not being used. Should I upgrade just as a precaution?
One complication is that I have renamed my user since the last time I backed up.

the problem is with the WD Passport drives. I also have one, and since upgrading to 10.9 I can no longer use mine either. See if this solution works for you: https://discussions.apple.com/message/23943103#23943103

I have an issue with time machine, it doesn't find the Lacie external driver it use to use. it is the same drive that I usaly use for time machine back ups. It is corectly plugged. What can I do ?

Hi,
I'm trying to back up my macbook with time machine on the Lacie external driver I usualy use for this, but today my computer doesn't find the driver. I haven't done back up in 6 month.
Today, the Lacie driver is pluged and running, but the computer just does'nt find it.
what shall I do ?

Some things to consider:
Is the drive mounted, i.e., visible via Finder and/or on the Desktop?
Is the drive still selected in System Preferences, Time Machine? If not, use the "Select Disk" button.
Is Time Machine still turned on (System Preferences, Time Machine)?
Can you see the drive (and mount it) using Disk Utility (in your Utilities folder)?
