Time Machine slow when backing up internal RAID

I've had some issues for some time now with Time Machine taking forever to backup information from my internal RAID in my MacPro. When I say forever, I don't think Time Machine is able to back up every hour, even if it's just doing the 44 mb backup. That can sometimes take 3 hours. I just determined today that it was specifically having trouble with the RAID. I copied a bunch of information to my OS drive, and WHAM, time machine was flying! I primarily work off of my RAID as this machine is used for video editing. The RAID is an 8tb RAID 0. The time machine volume is a GTech GSpeed 9TB RAID 5 connected via eSATA.

Bump for a monday, and hopeful for some replies.

Time machine slow to back up tiny amounts of data

I'm running Snow Leopard 10.6.8 and trying to be satisfied that Time Machine has actually backed up my entire computer. It's running hourly, but backs up something like 50mb when there's nothing happening between backups. That's fine - I get there may be system files that change connected to the network.
But why does it take 20-30 minutes to back up this tiny amount of information via firewire? The backup drive is a 2TV drive with 500GB free. The imac has 12GB of RAM and 300GB of free space on the 1tb drive.
Right now it's been 15 minutes and says it is backing up 66kb of 2.6mb.
Then when it completes, if I restart Time Machine, it might find another 1gb to back up. or it finds 50K ITEMS to backup, again with nothing being done on the machine. Seems random.
Having experienced a nightmare restoring from a time machine backup on another machine, I'm not sure how you know if it's actually a "complete" backup? There are no parts of the drive excluded in TM Options.
Thanks

Time machine error when backing up iMac with internal flash and sata internal drives.

will appear to be backing up and then as just about done, shows Time Machine Error message and ask you to
try again later, if problem persists, repair backup disk with disc utility. Neither solution works.

Time Machine stalls when backing up server data

I have an Xserve set up as a Workgroup Server at one of my locations. I've decided to simplify the backup scheme at this location, so I'm doing away with my shell scripts and just turning on Time Machine and pointing it at a large external array. This way I can enable a few selected users on site to easily retrieve files from the backup. I've done this a few times, to much success.
This time, I'm experiencing a new problem which I've not been able to solve. The users in this workgroup have quite a bit of data, about 1TB, much more data than I've dealt with using this setup.
*The Problem:*
Time Machine begins copying data during the initial backup and achieves a transfer rate of about 10MB per second, not spectacular, but fine. When the backup reaches about 80%-90% complete, it stalls or slows to a crawl. It gets to about "900GB of 1.0TB" and the transfer rate slows to about 1MB per minute. Time Machine does not deliver any errors. It continues to back-up, just very slowly. So slowly sometimes it appears to be stopped.
I am backing up to a sparsebundle disk image, just like Time Machine will do over the network.
*I Have:*
• reformatted the destination volume
• disabled Spotlight indexing on the destination volume
• disabled Spotlight indexing on the source volume
• copied the data directly to the destination volume using Finder (with success and fast performance)
• reset the Time Machine preferences
• used the default disk image Time Machine creates
• used a disk image with a 4TB size limit
• used a disk image with no partition layout
• used a disk image with a GUID (GPTSPUD) layout
• used a disk image with a Apple Partition Map (SPUD) layout
• used a disk image with increased band size (128MB)
• connected to the backup array using FW800
• connected to the backup array using USB 2.0
• unlocked all files on the source volume
• set all permissions on the source volume (chmod)
The system is an Intel Xserve, 10.5.7, 2.8Ghz, 2GB RAM, 80GB boot drive, 2 x 1TB data drives. I am only backing up the data being shared to the workgroup, not the server boot volume. The destination volume has plenty of available space.
Checking the logs (Console filtering for 'backupd') reveals several of these errors:
+8/27/09 12:27:51 AM com.apple.backupd[45548] SystemFlippers: Consumed too much data for FREF ID 131 (pBase = 0x4f839c0, p = 0x4f83ac6, pEnd = 0x4f839c7)+
+8/27/09 12:27:51 AM com.apple.backupd[45548] CoreEndianFlipData: error -4940 returned for rsrc type FREF (id 131, length 7, native = no)+
I don't have enough foo to make sense of those errors or even tell if they're related. I also don't know if 12:27 AM is when the backup began to slow down.
I anticipate some answers will be "Time Machine was built for end users not servers", "Time Machine wasn't intended for this purpose." Which I don't necessarily agree with in this case. For the purposes of discussion, this machine could be considered just a desktop with file sharing enabled, backing up the same amount of data.
I've tried to provide as much information as I can think of, and appreciate any feedback.

It's a bug and should be reported to Apple's feedback.
Even though TM is failing in the manner described, is it backing up up your data correctly ?

How does time machine work when being used with a mac pro?

How does time machine work when backing up a mac pro?
Considering the fact that the mac pro can hold 8TB and a external (non NAS) hard drive can hold only 2TB does time machine only backup the OS disk.

Time Machine will backup everything by default, on every disk in your Mac.
Choose System Preferences > Options to exclude items. You could exclude everything except your OS...but I'd think it is your data that's more important to you, if you have to make choices.
See...
http://discussions.apple.com/thread.jspa?threadID=1964018
While it's true you can store almost 8TB, how much do you think you'll actually store? If you have 1TB of data you want to store then a 2TB drive can do it. Also when your TM drive begins to get full it will begin deleting the oldest backups to make room.
You could also get a Drobo with 8 bays...

After updating my MacBook Pro to yeosemite I want my old screen saver picture back. I did a full back up before the install. I found the "Settings" folder in Time machine but when I try to open it I get an error message saying "You can not open this

After updating my MacBook Pro to yeosemite I want my old desktop picture back. I did a full back up before the install. I found the "Settings" folder in Time machine but when I try to open it I get an error message saying "You can not open this folder. It is in TimeMachine".

Can you browse the Time Machine drive from Finder?
If you can and you know where the picture was stored ie on your desktop you can browse through the folder structure to the picture copy it and paste it somewhere on your new install before right clicking it and 'set as desktop background'

When you boot the new machine for the first time, you'll be prompted to import your data from a Time Machine backup.

Time Machine stalls when trying to back up to Time Capsule or an external hard drive.

TIme Machine stalls when trying to back up to Time Capsule or an external hard drive. Time Machine shows a message such as "Backing up 4MB of 9.00GB" but nothing happens for hours.

Are you really running 10.6.4 OS?
What model TC and what firmware?
Wireless or wired?
How is the TC setup?
If TM can work to neither a TC or external hard disk it is more likely the computer is faulty hard disk..
Do a verify of the disk.
See A5 here.

I am getting this error when time machine tries to back up to a time capsule. "The backup disk image "/Volumes/JUDY ARCENEAUX's Time Capsu-1/JUDY ARCENEAUX's MacBook Air.sparsebundle" is already in use." Same time capsule has worked in the past.

First, restart the computer and the Time Capsule. In most of the cases, this should solve the problem.

Time Machine Freezing when moving files it's backing up?

Hi, once in a while time machine will freeze up and I can't do anything with my external drive or any of its partitions unless I disconnect and reconnect them. I couldn't figure out what it was until I realized I had moved a new movie file at the same time Time Machine was probably backing it up.
Has anyone else experienced this problem?

That will happen with most backup utilities. If they don't freeze they certainly will become very confused. You should never do something like that during backups.
Ideally the backup utility shouldn't freeze but I don't think most programmers anticipate such an action so the utility has no built-in mechanism for dealing with it gracefully. So I think you should file a bug report with Apple. You can do so at the Feedback Page.

Time Machine won't back up to drive. Five days backing up so far

A week ago I got a message saying that Time Machine could not back up to my external hard drive but that I could access my old backups. I pointed Time Machine to another hard drive and it has been backing up there for five days so far - all the time stating Time remaining 5 seconds. It is now in a cleanup mode. I have been reading about various bugs concerning Time Machine and wonder if there is a fix I can carry out so that I can use the original external hard drive again.

Stop the backup. Boot in safe mode and log in. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Time Machine won't back up onto Time Capsule

I upgraded to Mountain Lion last week, and Time Machine won't back up to my Time Capsule. When it fails, I get the message:
Time Machine couldn't complete the backup to "Tom's Time Capsule".
The backup disk image "/Volumes/Data/TomsMac.sparsebundle" could not be created (error 60)
I sometimes get the same message, but with "error 17"
I also get the following error message popup (even though the disk is the one in my Time Capsule):
The disk you inserted was not readable by this computer.
The popup offers three choices: Initialize, Ignore, Eject.
My local Apple Store Genius concluded that the problem must be with the Time Capsule, so I bought a new one. That didn't fix the problem.

I did a re-install of Mountain Lion and that didn't fix anything.
My MacBook Pro is accessing the Time Capsule wirelessly, as it always has.
Help!

Just to be sure, we're talking about a Time Capsule -- not an AirPort Extreme connected to an external hard drive. Right?
If so, proceed as follows.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I ereased my external drive now time machine doesn't back up. What should I do?

I ereased my external drive now time machine doesn't back up. What should I do? the reason I ereased was because backups wouldn't finsh because of disk error. I did disk repair. Still wouldn't back up so ereased the back up drive. Now nothing appears on it. On the internal drive of my imac in Appllications Timemachine is still there. When I click on it it goes to a screen that looks like a night sky and nothing more happens. Do I need to download some software?

Time Machine doesn't work on 10.4.7. It didn't become available until 10.5. Use a different backup software if you are going to use 10.4.7*:

Time Machine will not back up to My Passport Edge for Mac. How do I delete the aliases to make room?

Time Machine after running for a few weeks says 'Time Machine couldn't back up 'My Passport Edge for Mac', also new. It needs 365.05 GB only 49.94 are available.
When I click on the My Passport Edge for Mac, I see that it has alias for each file. How do I delete the alias in order to backup my Time Machine???

You do not ever delete anything on the Time Machine drive using the Finder.
Those Alias files are essential to the internal operation of Time machine, and is what allows it to keep only one copy of a file that appears, unmodified, in multiple Backup Sets. If you modify them in any way, you risk Time Machine losing ALL your data.
I expect your backup drive is simply not large enough to do what you are trying to do.
To learn about Time machine, start on this page and keep clicking on the ( next page ) links for additional pages in the linked articles:
How Time machine works its magic
Your best short term solution may be to start a new backup, which will be smaller that the multiple backups on your existing drive. In the long run a Drive 2.5 to 3 times the size of what you want to backup is recommended.

Time Machine isn't backing up external drive

I've been using Time Machine successfully for some time now. Recently I decided to move my iTunes music to an external drive (my internal drive was nearly full.) So I moved 150+ GB of iTunes library to the external drive successfully, but Time Machine seems to completely ignore the external (FireWire) drive. It's formatted as Mac OS Extended (that's HFS+, right?) so I don't understand what the problem might be.
Also, if I can get Time Machine to start backing up both drives correctly, should I erase the backup drive and start over? Otherwise, I assume that I'm going to be wasting a lot of (backup) drive space, since the 150GB iTunes library will be backed up from its original location on my internal drive, as well as from its new location on the external drive… what's the best way to deal with that?
Thanks in advance for the help.

You may not need to. TM will, eventually, delete it's copies of anything not still on your internal HD. When is just a question of how soon the TM drive/partition gets near full, and TM must start deleting your oldest "weekly" backups. You are supposed to get a message about that, if you have the appropriate box checked in TM's Preferences, but several folks here report they never did, so assume nothing.
Still, if you want, you can delete all the backups of a file or folder. Enter Time Machine, find and select the folder in question (presumably iTunes on your internal HD) in one of the "cascade" of Finder windows, then click the "gear" icon. That will give you an option to +Delete all backups of <folder>.+
You'll then get a confirmation prompt (may take quite a while, considering the size), then the usual place to enter your Administrator's password. The actual deletion will probably take quite a while, also. There was a report the other day that the item was still visible for quite some time after TM seemed to have finished the deletion, but eventually it did disappear.
Then make some change to the folder, or something within it, so TM will consider it changed and back-up the new (smaller) version.
