Large Time Machine Backup and Airport Extreme Bottleneck

Network Configuration:
Wall-Cable Modem (no wireless)-Airport Extreme-D-Link Switch (to extend the ports)-Devices
Three devices are plugged into the Airport Extreme. A wired connection directly from this computer, the D-Link Switch, and another remote wired connection.
In the switch I have plugged in, among other things, a Drobo5N NAS with 16TB worth of disk storage (netting 11 roughly usable space).
I am a photographer who has been at it awhile (10 years plus), so I have a large cache of picture files stored in RAW format.
On my local MacPro I have a pair of 1.5TB disks installed internally in a RAID 0 array for nearly 3TB of storage. I use most of it. The MacPro otherwise is unremarkable. I reconfigured it with an SSD boot disk and it has the original HDD drive along with an extra to fill out the remaining bay. My overall storage requirements for backup are 3.05TB.
I started the TimeMachine backup over the network and the performance seems slow. It ran some numbers out of the console and it looks like it's copying an average of about 5GB an hour on average.
I tried to do a quick review of the router settings but when I called up the Airport Utility it takes an extremely long time to show information. Since I started this thread, the message "Reading settings on (my) Airport Extreme" has been up, then finally as I was typing this line the information came through. It seems the router may be a bottleneck, but I am not sure.
The backup has been running 4 days and is about halfway done.
So where to go from here? Is this kind of performance in Time Machine the norm? Is the Airport causing this problem? If so, do I need to check for some sort of software upgrade or missing configuration? Not sure where to go next, but I am pretty sure I can move more than 5GB per hour over my network.
Any help appreciated.

Answered in your other thread. Please don't double-post. Thanks.

Can two macs use same disk for Time Machine backup with Airport Extreme?

Hi
I use a Western Digital disk as a wireless Time Machine backup connected to the USB port on my Airport Extreme and it works great. My question is: can my girlfriend use that same disk for Time Machine backup from HER computer too? (I don't mind formatting the disk if needed.)
If she can't, is it then possible to connect a USB hub and have two disks hooked up to the Airport Extreme?
Thanks for helping. I am constantly in awe of all the help people like you give people like me. Thanks!!!
Jakob

I've gone through the manual setup and the assisted setup and can't seem to get my MacBook to use the Time Machine. Any thoughts or help would be greatly appreciated.
Well, as the Jolly Giant points out....+this type of configuration is not supported by Apple+, so it's difficult, if not impossible, to provide a fix for something that Apple says that you cannot do. Reference these Apple Support documents regarding this topic:
http://support.apple.com/kb/HT2038
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
Your situation is not unlike other users who try this and find that one computer may backup...(usually for a limited time before corruption issues start to creep in)...but another computer cannot backup. Count me as one of those users who thought that because things seemed to work that I had somehow "beat the system".
I started getting the corruption error messages after 4-5 weeks of successful backups, so I figured that it did not make sense to continue to try to get a second computer to backup (yes, I too could not setup a second Mac to backup).
Sorry, I could not get a second machine to backup, so can't tell you how to accomplish that goal. If you want to continue to try backing up this way, you might want to also think about a second backup strategy...just in case backups become corrupted on the WD drive.
Maybe if Apple says you cannot do this, they just may be right?

Time Machine disk and Airport Extreme issues

I have a portable USB drive I use as my Time Machine disk. It works great, but only when I manually mount the disk.
I recently got an Airport Extreme, which allows me to mount a disk off of it. So, I figure I'll mount my USB Time Machine disk there so Time Machine backs up hourly.
Well, the first issue I get is that Time Machine tells me the disk isn't properly formatted! Odd, since I've had it configured via the app for backups. I go into preferences to select a disk, and I choose my Time Machine disk. When I next tried to run a backup, it indicated I don't have enough room on the disk, requiring ~106 GB .... almost as if it thought it hadn't done any backups before and was going to run a full one.
I dismounted the drive from the Airport Extreme and hooked it back up locally, and I get the same results within Time Machine.
I also noticed a new file on the root of my Time Machine, with a .sparsebundle extension. Is this related in any way?
Anyway, what can I do, short of a full reset of my Time Machine disk, to get it working through my Airport Extreme?

Me again ...
I hooked up my USB TM disk again to my Airport Extreme. I don't see it as a mounted drive in my Sidebar. However, I see it under the Devices on my sidebar, under "my" computer, then Time Machine Backups, then a backups.backupdb folder.
To start fresh with TM backups I'll need to erase the drive. From what I see, do I just delete the 'backups.backupdb' folder and its contents?

Continue Time Machine Backup with AirPort Extreme

Hi,
if've done my backup via usb, now i am owning an AirPort Extreme and would continue my backup; but Time Machine had start a new backup, how can i continue my old backup.

yes, I'm aware of such procedures but it's not worth the trouble in this case as the OP has only done one backup. also, it would require a separate hard drive to put the sparse bundle on temporarily before cloning the current backup drive to the sparse bundle. lastly, no need to rsync in this situation. you can simply erase the external drive and copy the sparse bundle by hand back to the external once the cloning is finished. but all in all entirely not worth the trouble in this case.

Can i use time machine with a airport extreme and a external hard drive

I have connected a hard drive to my airport extreme.
Now i would like to use time machine to back up my computers, and would like to do this on the hard drive which is connected to my airport extreme.
Next step is that i would like to be able to approach my external hard drive via the internet.
Is this possible or not?

Both are possible. However, Apple does NOT support Time Machine backups to AirPort Disks attached to the 802.11n AirPort Extreme Base Station (AEBSn). Doing so will potentially lead to data corruption and is highly not recommended. Please check out this excellent Pondini article for more details. This article also provides the Apple Support references that states Apple's position. Bottom line? If your backups are critical to you, then you may want to rethink your backup solution.
As far as accessing the AirPort Disk from the Internet, the following is the basic steps to do so:
Start the AirPort Utility > Select the AEBSn, and then, note the IP address shown.
Select Manual Setup.
Verify that Connection Sharing = Share a public IP address is selected on the Internet > Internet Connection tab.
Select Disks, and then, select File Sharing.
Verify that both the "Enable file sharing" and "Share disks over WAN" options are enabled.
Verify that Secure Shared Disks = With a disk password. (Recommended)
Verify that AirPort Disks Guest Access = Not allowed. (Recommended)
Select Advanced, and then, select the Port Mapping tab.
Click the plus sign to add a new port mapping.
For Service, select the "Personal File Sharing" option. (Note: This option would only allow Mac clients to access the AirPort Disks. If you want both Macs and PCs to connect, you would need to leave this field at its default value and enter the appropriate SMB ports to the mix of ports to be opened.)
In the Public UDP Port(s) and Public TCP Port(s) boxes, type in a 4-digit port number (e.g., 8888) that you choose. In the Private IP Address box, type the internal IP address of your AEBSn that you wrote down in step 1. In the Private UDP Port(s) and Private TCP Port(s) boxes, type 548. Click Continue.
In the Description box, type a descriptive name like "AirPort Disk File Sharing," and then, click Done.
Click on Update.
To connect to the shared AirPort Disk from a remote location using a Mac:
From the Finder > Go > Connect to Server.
Enter the Pubic (WAN-side) IP address of the AEBSn, followed by a colon and the Public port number that you choose in step 11 of the previous procedure. For example: afp://www.mydyndnsdomain.com:8888 or afp://123.456.789.123:8888
Click Connect.
You should be prompted for your user name and password. The user name can be anything you like; the password should be the Disk password for the AEBSn that you created in step 6 previously.
Click Connect.

I Can't Backup to time machine through my airport extreme.

I Have recently paritioned by backup disks into two separate partitions and i now have the nice view of time machine because i switched to the GUID format. However, now i cannot backup to time machine through my airport extreme. Please help, it is very frustrating.

No you can't and the reason is Apple blocked the ability for Time Machine to backup over WIFI to a NAS connected to the AEBS. Though I was able to use iTimeMachine to enable the feature prior to the recent Leopard update 10.5.2 which seems to have closed this ability once again. Apple's comment to me was to buy Time Capsule claiming the feature was never supported over WIFI with the AEBS even though their advertising just prior to Leopard's release stated differently. A lot of us on this forum paid for an AEBS and NAS drive based on Apple's own advertising regarding a feature they later blocked/removed and are extremely upset with the way the issue seems to be ignored by Apple support who pretend there was never an issue to begin with.

Used Time Machine (USB) to Airport Extreme

Hi,
Last year, I set up a 1TB external hard-drive as my Time Machine... It all worked perfectly. Currently it has over 600GB worth of stuff on it. My macbook has a hard-drive of 320gb.
I recently bought a used Airport Extreme (A1354) and want to connect my existing 'Time Machined' external hard-drive but it won't allow me to...? It is recognised- I just cant seem to back up or access files at all.
In an article I read it said that the pathway when connected directly to my macbook via USB is different to a pathway when connected via wireless connection.
So my questions are:
• Can I rename the pathway?
• Or do I need to buy a new external harddrive and start afresh?• If I do have to start a fresh, is there a way to merge my old time machine files to the new time machine files - - - so I can keep both my 'time Machines" in the one place (Instead of having one lot of time machine from August 2011 to August 2012 and another time machine from September 2012 to x date)
I can't even restore all my time machined files to my macbook- then reformat my External Hard drive, because I only have 320 GB
I hope I am making sense. I am not too high tech so . . . my apologies =)
P.S. Sorry if this has already been answered-- I have read countless articles and can't seem to find an answer.

Hi,
Yeah I got an answer to connecting my existing time machine to my airport extreme
The airport extreme will not let you connect any 'time machine' - new or existant - as it acts as a drag and drop type of saving.... so i.e. if I want to save a file - i will need to go to shared>airport extreme and then drag and drop my file there to save it- it will not do it automatically like time machine. This is so if you wanted the automatic wireless backup, you would have to go out and buy a time capsule.
hope that makes sense.

Time Machine backup and main drive corrupted. Help! (REWARD OFFERED)

Here's the deal:
I have a Macbook Pro and a Mac Mini both runnign Snow Leopard. I use the Mac Mini as a kind of media center / server, it has a few external drives connected to it. On of these drives (1GB) is dedicated to Time Machine, the Mac Mini (80 GB hard drive) backs up to it directly and the Macbook Pro (500 GB hard drive) does it over the network (Time Machine created a sparsebundle). This has worked well for years now. Occasionally I got the error that Time Machine needed to start a new backup because the old one was corrupt. That happened about 2-3 times a year (did the same thing when I backued up via USB). Now about 2 weeks ago, that error came up and I just let the Macbook Pro on overnight and connected the ethernet cable for faster transfer.
When I woke up, the Macbook Pro didn't respont at all, spinning beachball, no response at all beside mouse movement. I let it do it's thing for another 10 hours (while I was at work) and just held down the power button to power off and restart it. But all I got was the gray-on-gray flashing folder with the question mark in it, that's what you get when the Mac can't find bootable partitions. So I popped in the OSX Snow Leopard install disk, ran disk utility. It saw the hard drive, but no partition (i.e. Machintosh HD) on it. I checked the Time Machine backup and the sparsebundle was 300 GB (the Macbook Pro had 400 GB used, the remaining 100 GB were free). There is no way to restore from an unfinished Time Machine backup...
First thing I did was clone the internal (Macbook Pro) hard drive to a DMG disk image using DiskDrill (the only program I found that could recognize the drive at all, not even DiskWarrior could). I also bought the exact same hard drive model and partitioned it like the cloned the corrupted hard drive to the new one using ddrescue (a command line tool that doesn't quit upon i/o errors but proceeds and tries to recover as much as it can). It copied everything except 65 kilobytes, the corrupted drive seemed to be physically damaged in a bunch of sectors relatively at the beginning of the disk. Since I had now an exact copy on a fresh, healthy drive, I went crazy trying out Disk Warrior (didn't recognize the drive at all), data rescue, testdisc, p a Windows isk, etc. Only R-Studio (on windows) showed the EFI and Macintosh HD partitions on there, they started and ended on the same sectors on the corrupted drive and its clone. After some research, I figured that the partition table was corrupt so I reformated the clone disk using the OSX Snow Leopard install disk (1 HFS Journaled Partition with GUID Partition table). R-Studio showed the EFI and Macintosh HD on that reformated drive, again, same sectors as before. So I figured I could just copy just the bytes where the Macintosh HD starts from the corrupted drive to the clone (using ddrescue). That worked, after almost 24 hours, I had the clone drive with a "disk1" partition on it that even disk utility could see.
Now I was able to run Disk Warrior on it, but all it could do was recover a few Application folders (Resource-Folders and lproj-stuff), about 100 MB in total. It couldn't repair more of catalog file apparently. Luckily, Time Machine backed up quite a bit (300 GB out of 400 GB of data) and I was able to manually copy all the Dokuments, Desktop, user Library, Applications, Music, Download and Movies. Unfortunatley, only a little bit of the Pictures folder was copied. iPhoto library (80 to 100 GB) was nowhere to be found, backup must have failed right then. I can salvage the drives (time machine drive, original hard drive with a few broken sectors, DMG-image of that drive, 1-1 copy of that drive with partition table repaired) but that only gives me files with numeric names and today's date on teh JPEGs (instead of the date the picture was taken).
Is there any way I can recover that iPhoto library? It appears the catalog file got corrupted because the hard drive (only 8 months old...) failed on a few sectors. If I understand it correctly, the catalog file on HFS+ file systems is where the folder structure and file names are stored in a B-Tree. I can't imagine that some i/o error during backup can totally annihilate that file when it was working perfectly before. Here's a few things I want to try out but haven't figured out how so far:
- Time Machine had to start a new backup. There's plenty of free space on that drive so there's a good chance there's old data left on it. Is there a way to restore files (including file names) and fodlers from deleted time machine backups?
- Is there any way to re-build that catalog file from what is there left on the original hard drive? I can't imagine 65 kilobytes destroys it all.
- Are there other ways to recover my iPhoto Library? The raw JPEG (and AVI) files with correct file names or metadata would suffice.
Thanks in advance for any help, I'll actually reward the person with a working solution, 5 years of photo memories are somewhat important. It really ***** that a failure during a backup destroys that...

Final Update:
The catalog file on the original hard drive could not be fixed. Seems like Mac OSX tried to repair the catalog file while the sectors this file resides on failed. To make things worse the partition table was also broken beyond repair, even overwriting the sectors with a new correct partition table didn't help. DiskWarrior found less then 100 MB worth of stuff, mainly Applications folders.
I recovered pretty much everything from the incomplete Time Machine backup by right-clicking the sparsebundle and browsing through the folders with the long alphanumeric names, looking for the version of the folder with the most files in there. All I was missing was part of the ~/Pictures folder, i.e. photobooth pictures and the whole iPhoto Library. My best option was to recover these files using data recovery tools.
DiskDrill proved to be the absolute best, fast, responsive, efficient, and the only one able to mount the DMG-file with no valid file system on it. As there were many i/o errors and broken sectors on the original hard drive, I made a copy of it using a free command line tool called ddrescue (the standard dd tool just aborted when it encountered the i/o error). ddrescue copied the whole drive to a DMG image, I had 56 kilobytes with errors on the first pass, but it managed to shrink that down to just 4 kilobytes (wow!) after the second pass where it tries to re-read the broken secors. It took about 24 hours for a 512 GB 2.5" drive (5400 rpm) but well worth it. Be advised that ddrescue is really persistent and tries everything to recover those last errorneous bytes. At the very end of the process, the read/write head of the hard drive just goes wild trying to catch the data on the sectors with different momentum. This works but I assume this is pretty damaging for the original drive. I also copied it all to a new hard drive (again using ddrescue) and tried partition and catalog repair tools on that (DiskWarrion, testdiks, pdisk, etc.). Still no hint of a good result.
I made a deep scan on the clone hard drive with DiskDrill. At the end (after about 8 hours over USB) it found 13 partition (I assume that's the Macintosh HD, EFI and some DMG files lying around) and hundreds of thousands of pictures. I restored some JPG files just to check the quality, some were damaged, some were good with all the EXIF data intact. I just made it copy all JPG files into a folder. I know the pictures taken from my camera produce JPGs larger than 1 MB and smaller than 5 MB, so I sorted them by size and moved the smaller and larger files into seperate folders. I took the remaining folder (100 GB) and just dragged it into iPhoto. It imported them overnight. Auto-Split by events and I got my library back, alas with different file names, originals and edited versions side by side, lots of duplicates, some damaged, some not. But hey, all the pictures in chronological order. Okay there was also one large event with all the JPGs without valid EXIF data landed inside, iPhoto just takes the file creation date (i.e. the date where the recovered file was copied). As far as I can tell, these are all just data corpses, halfway overwritten copies, random pictures from the internet, desktop pictures, etc.
I started to work my way back through the events, deleting the duplicates and renaming the events. There's an app called "Duplicate Annihilator" which apparently can find duplicate pictures in iPhoto and mark them for you. The free version only does 500 pictures but if it works, I'll get the full version. It can mark th eduplicate photos by adding something to the picture comment in iPhoto so you can manually review it all. Good stuff!

Using a Time Capsule for Time Machine backups and as a data drive

Hi There....can I use my Apple Time Capsule for my Time Machine backups and as a drive I can put data on?

Yes, you can use your time capsule as a drive for data. If you create a disk image, you reserve a certain amount of space for that image. Time Machine will respect that space and leave the disk image alone even if there is a large amount of unused space on the image.
If you create a folder, it starts with zero space until you add data to it. The folder can be as large as you would like as long as the space is available on the TC.
So, each has an advantage. The disk image will reserve the space until you fill it up and the folder will not. But, the folder can be as large as you would like as long as the TC has space available.
Your next question might be can you change the size of a disk image after it has been created? I haven't tried this, but think you probably could.
For most users, I think the folder concept is probably simpler for them to use and easier to understand. But more advanced users may favor the disk image concept if they feel that space will be at a premium on the disk.

Can Time Capsule backup an Airport Extreme's attached USB hard drive?

Can Time Capsule backup an Airport Extreme's attached USB hard drive (without currently being attached to a MAC OSX LION system)?

No, sorry.. there is no way for the TC to see the files.. and even if you plug the hard disk into the TC there is no mechanism in the TC to drag the files to itself.. The TC is absolutely a dumb network attached drive.. everything you want to do must be done from a computer.

All of my files are stored in a separate hard drive with only the actual app having been on my Macbook. Should I just reinstall?

Hi
To run Mouitain Lion you need to update Logic.
For the updaters to work the Logic application must be:
a) Within the Applications folder, and not in any sub-folder
b) Named "Logic Pro" with no extra numbers or spaces

Use TC 2TB for Time Machine Backup and Storage simultaneously?

Hi
I am planning to buy a TC 2TB.
I would like to know if the TC can be used as a Time Machine backup device and for storage simultaneously?
for example:
Can I use 1TB for Time Machine backups and 1TB for storage.
Please let me know if this is possible?
Thank you

I tried for ages to seek a relatively easy way to do this.. i.e. partition it, it's a huge pain! You can, but i'm pretty savvy and got bored and confused! What I did do was switch the TM back-ups to manual so they don't end up filling the disk. Trust me it's the easiest and best option!

Time capsule as time machine backup and NAS?

I've read the TC section of the website and notice a blurb about computers able to connect to it as a HDD.
I realize the device has yet to be released but was wondering about this. I have a handfull of macs and a handfull of xp machines on my network (wired and wireless)
1 of my XP machine is just used as a file server. (1.5TB NTFS formated holding all video/audio/docs as well as having iTunes running to download HD podcast) All computers (Mac/XP) can access this. Five of my XP computers are MCE2005 which are configured to record SD and HD shows directly to this box.
I have yet to have a HFS formated drive to actually do time machine backups and I would like to start. I understand that going with TC I will loose some abilities I currently have by running a dedicated computer/file server but I like the fact that it is small and self contained.
I just want to make sure I understand the specifiations correctly. Can I make a various folders on TC and then map it to my Mac/XP machines via windows naming convention (ie \\TimeMachine\RecordedTV\)
I am in the process of upgrading my file server so this would be a perfect time to think about going this route. Should TC not meet my needs I will continue with my build of a Raid 5 server.

Until we get more information, at the present time the only certain thing we know about Time Capsule is that it will support TimeMachine backups.
What we don't know:
1. whether TimeMachine backups to network drives other than Time Capsule will ever be supported
2. whether the Time Capsule internal drive can be used for general file storage, or only Time Machine backups. Current information on Apple's web site could be interpreted either way. I suspect it can be used for general file storage - but that is just my opinion.
If it is not essential that you make a purchasing decision before Time Capsule ships within the next month (and more detailed information becomes available) I suggest you wait. My two cents worth of opinion - if it is general file storage that you want, and Time Machine automated backups are not a priority on the "wish list", then I think you would be far better off setting up your own network file server rather than using Time Capsule for this purpose.

Is it possible to use an external hard drive for time machine backup and also as a regular hard drive?

Is it possible to use an external hard drive for time machine backup and also as a regular hard drive?

I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

How to restore a Time machine backup and get a recovery partition?

Hi,
I'm quite confused!
I restored from a Time Machine backup and then setup boot camp (and removed that partition a while back) and now I don't have a recovery partition. (Can't enable File Vault and
bash-3.2# diskutil list /Volumes/Macintosh\ HD
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   2:                  Apple_HFS Macintosh HD            87.4 GB    disk0s2
My new MacBook Pro didn't come with any CDs.
Apparently I need the recovery partition to reinstall Lion from the internet.
"Recovery HD offers on-disk recovery tools, allows you to restore from Time Machine backups, reinstall OS X Lion over the Internet..."
The recommended solution from Apple seems to be reinstall with your OSX 10.6 CD (which I don't have) and then upgrade to Lion (which seems like a PITA).
Info from : http://support.apple.com/kb/HT4649
What process should I follow to restore my recovery partition and apply the current state of the machine from a backup?
(the process should not involve anything I don't have, like USB memory sticks, Lion CDs, etc....)
Supplementary questions which are only relevant if the answer is "you can't" (which would seem to be a major bug!) :
Or is there a clever method to install a recovery partition onto an existing disk (which clearly has space for it)? I have searched for it but all the results I found have either not mentioned that it works without reinstalling but look like it's needed, or do say "reinstall".
If I install Lion to an external disk, can I boot from that and use the recovery disk assistant tool to restore the partition to my internal disk? (Which I assume I'll need to do to get FileVault to work) ?
Thanks,
Max
