Time Machine can't create backup on Synology NAS DiskStation (Error 17)

My first time trying to use Time Machine.
Configuration iMac: OS X vers. 10.7.3, 2.5 GHz, 4 GB Memory, 500 GB Disk
Destination of Backup: Synology NAS DiskStation DS212j, Mac File Service for Time Machine activated, user for Time Machine created
Log reports:
Starting standard backup
Network destination already mounted at: /Volumes/TimeMachine
Creating disk image /Volumes/TimeMachine/JoeiMac.sparsebundle
Error 17 creating backup disk image
Failed to create disk image /Volumes/TimeMachine/JoeiMac.sparsebundle, status: 17
Backup failed with error: 20
What means "Error 17"?
Any idea what went wrong?
Hope you can help.

That's the problem with using a 3d-party NAS with Time Machine; it has it's own software that's supposed to interact with OSX, and when something goes wrong, it can be very hard to sort out just what and where the problem is.
First, make sure that model is fully compatible with Time Machine on Lion (some are, some aren't), and install any software/firmware updates Synology has for it.
Second, make sure the names (of all odd things) of your Mac and network aren't too long and don't contain any special characters, per #C9 in Time Machine - Troubleshooting.
Third, make sure you're following Synology's instructions exactly.

Installed GoFlex 1.5 TB external drive on my iMac running OS X 10.7.4 and error says Time Machine can't create a backup folder. Any solutions?

Installed GoFlex 1.5 TB external drive on my iMac running OS X 10.7.4 and error says Time Machine can't create a backup folder. Any solutions?

Well, to unmount the drive, you can use the Terminal application.
Start in Applications > Utilities > Terminal.
When the Terminal window opens, type - without the quotes and with the space at the end - this:
"diskutil unmount "
Then drag the icon of the unmounted drive from the desktop into the Terminal window - the drive location will be added to the end of the command above. It should look something like this:
diskutil unmount /Volumes/volumename
Then press enter (return).
That should unmount the drive. Now you can try the Time Machine process again with perhaps a different interconnect cable for the GoFlex.

Lion's Time Machine - Can't create a backup?

Time Machine can't make a backup... I even went ahead and wiped out the drive and tried to create a new backup.
All it says is that it couldn't complete the backup and to try later as it might only be temporary.
This is critical for me and a not at all light in importance. Had I known this along all the other issues with Lion existed I wouldn't have upgraded. For now I am keeping my MBP safe from Lion...
I guess I just have to suffer the damage on my 27" IMAC..
I would use a BR Disk to do a back up of my files, but NO.... MACs don't support Blu-Ray disk drives, STILL!!
Apple you need to fix this and other issues.

Apple's ingenuity in their advances can be hailed by millions as I myself give them credit where credit is due, such as devices like the iPad and iPhone/iPod. But when a company only bothers to alert you to a couple of apps that Lion can't run and moves them to a folder for the user to delete or update but leaves devices and other industry standard software packages rendered useless with no warning when they have extensively tested their OS against 3rd party manufactured devices and software, whom they are partnered with, then yes they can share in the blame just as Microsoft takes the blame for operating systems that do the same such as VISTA.
I am sure that with enough time all of the 3rd party companies will undoubtedly get on board at some cost that will get pushed down to the end users. They will either update, upgrade or conform.
Apples mentality in the past hurt their stock prices, they used to only use their own Risc based processors and they refused to adapt and incorporate to the needs of their users desires for better faster chipsets and industry software such as Office. They adapted!
Refusing to incorporate the ability to use Blu-Ray technologies when companies such as Pioneer,LG, and Cyberlink are prepared to release the software for the Mac, Apple just has to give the go ahead, then yes, its their fault again. The industry in general isn't blind, they have a reason. Manufacturers want to create things that work with Apples Operating system and do, but they aren't allowed to release it without approval from Apple. They need Apple's support and acceptance for something like Blu-Ray to make it. Otherwise its just another hack and shunned by any cautious person that wants to make sure that their purchase won't cause them more problems than its worth. Blu-Ray is a matter of licensing and a major reason that Microsoft won't incorporate it into their own media player, but they leave it up to 3rd party software companies to absorb that cost and create their own players that can play back Blu-Ray movies within the Windows platform. Apple wants to keep Blu-Ray off of their machines as they can't obtain an exclusive license to the codec for Blu-Ray movies for Quicktime. The same mentality that they had before with their processors. So even the ability to read and write to the medium is out of the question.

Time Machine can't create space for new backups

For a couple of weeks my backups are failing. (Time Machine couldn't complete backup to "Time Machine Backups". The backup disk needs 156 GB for the backup but only 138 GB are available. Select a larger backup disk or make the backup smaller by excluding files.) I thought Time Machine was supposed to delete the oldest backups to make room for new ones? Thanks for your help.

It will delete the oldest backups, but when you have already deleted all of those, there will come a time when you will just run out of space.
If you don't think you should be at that point, tbirdvet is likely correct.

Time machine will not backup to Synology NAS DiskStation.

I own a MacBook Pro8.2 (15-inch, Late 2011) running on Mac OS X 10.7.5. Time Machine backups go to a Synology NAS DiskStation, which works fine with my wife's MacBook Pro (17-inch, Late 2011) also running on Mac OX X 10.7.5. If I try to backup the 15-inch MacBook Pro, I can get started but down the road I get the following message: "The backup was not performed because an error occurred while copying files to the backup dish". Try several times again but it always fails again. Does anybody have a good suggestion how to solve the problem? I am puzzled.

Most likely, the backups are corrupted. Try to Repair them, per #A5 in Time Machine - Troubleshooting.

Time Machine keeps re-creating backups

I'm having an issue with Time Machine on SL and wondered if theres a solution?
I'm running SL and use Time Machine to back up to a Western Digital NAS. All seems good and the backups seems to be fine, however every couple of days I get a message from time machine saying:
Time Machine completed a verification of
your backups. To improve reliability, Time
Machine must create a new backup for you.
Click "Start New Backup" to create a new backup. This will
remove your existing backup history. This could take
several hours.
Click "Back Up Later" to be reminded tomorrow. Time
Machine won't perform backups during this time.
I've checked the Apple support pages and it just says that this is an identified issue, but doesn't give a solution..
Has anyone else got any suggestions how to stop this? Obviously if I say 'Backup later', I don't get any more backups? As i'm am writing this, Time Machine is deleting a 310Gb backup file which is perfectly good, only to re-create it again and render me without a backup until the new one is created..

According to this Web page, what you're doing "may work as a destination for Time Machine backups, but it’s not recommended."

Time machine: can i create a separate backup for an external hard drive?

I am already backing up my internal hard drive to External Hard Drive A
I would like to back up another external hard drive (External Hard Drive B) to another hard drive (Hard Drive C). Is this possible with Time Machine in Mac OS 10.7.5. If so, where might I find instructions?
Thank you!

Sounds like you (or somebody) encrypted the disk with FileVault2.
When you enabled FileVault2, you should have received a message similar to the following:
WARNING: You will need your login password or a recovery key to access your data. A recovery key is automatically generated as part of this setup. If you forget both your password and recovery key, the data will be lost.
(That's the wording when encrypting the boot volume in Security & Privacy preference. The wording when creating an encrypted non-boot disk with Erase in Disk Utility is slightly different, but also includes red-letter WARNING about data loss if you forget the password.)
If the disk is encrypted with FileVault, better hope you can remember the password. As the help says, "The disk encryption in Mac OS X uses the government-approved encryption standard, the Advanced Encryption Standard with 128-bit keys (AES-128)."

Time machine can't open backups after installing Mavericks

When upgrading to Mavericks the installation failed with a disk error. In the shop they formated the disk and re-installed 10.6.8. It appear that there was nothing wrong with the disk anyway.
Of course formatting caused me to loose all data, but I had made a new Timemachine backup before the installation.
Getting the computer back with old OS and empty I called to ask which should be the order of the following:
1. Upgrade to Mavericks
2. Restore my data from Timemachine
Advice was the above so this morning I upgraded successfully to Mavericks. However when I would like restore data (after a few issues making the Mac see the external backup disk) it appears thet Timemachine cannot open the backups older than this morning. It can see then on the right side of the screen, though. Can anyone tell me how to access these backups made under 10.6.8, please.
Another challenge will be that iPhoto does not seem to exist anymore. So if the Timemachine backup gets to work, to where would I restore photos?
Kind regards
Morten

Explanation is that Time Machine created a "new" backup when backup disk was first time connected after migration to Mavericks. This backup was obviously empty, i.e. only containing Mavericks but no user data. Consequently Migration assistant would find no data to migrate.
Solution was to go to Backups.backupdb on the external disk (in Finder) and manually delete the backups created after the migration to Mavericks. Now the Migration assistant saw the backup I created just before the initial failed migration to Mavericks and could succesfully migrate all my data.
I guess you should be VERY careful with what you do manually on the backup disk, but I was out of options and the advice from the local shop worked.

Time machine can't make backup on external disk

I'm using an external disk to make my backup with time machine. Therefore I formatted the disk for Mac OS Extended initially and the first backups went fine.
Now backup never finishes successful.
The external disk is connected via my airport extreme (wireless). I already did a disk repair but this didn't help either.
What is causing the problem and how can I fix it?

Technically, that is not supported by Apple, although many folks (including me) are doing it anyway: http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html

Mac Time Machine - Can't Access Backup

Successfully connected Canvio Home and installed all software. I have run several Time Machine Back-Ups. When I look in Finder I see the Canvio, can navigate to other folders on the Canvio, can copy files to/from the Canvio from Finder, but cannot access or view the folder where the Time Machine backup should be (CLNAS-BACKUP, where CLNAS is what I renamed the Canvio to).
When I try to connect to CLNAS-BACKUP I get a "connection failed" message. But when I try to click on the "Connect As" button to connect as a different user - the login dialog box does not display. I am able to disconnect and reconnect to the public folders on the drive. and I've tried ejecting and reconnecting to the drive - no change.
Not sure if this is a Mavericks issue or a Toshiba issue. Really hoping for the former, as I have tried three other network drives and none have successfully completed a back-up - Toshiba was the first. But not much use if I can't access the backup

Time Machine - can't see backups

I have a 1T LaCie attched via USB and have been using since Sept 2008 - when i enter TM all I can see is back ups for Sept & Oct 2008, but nothing since. It seems to be backing up on a regular basis, and I get no warning messages. Can I just delete the backup file on the LaCie and start over if I don't care about files prior to what is on my HD now?

So, thanks to a rotten power supply I have a freshly dead 17.5 month old 1 TB Time Capsule which is out of warranty. To try and preserve the utility of my prior Time Machine backups and what seems to be a perfectly good 1 TB HD, I bought a 3.5" SATA enclosure with USB 2.0 and pulled the drive out of the TC and put it in the HDD enclosure. Now following Pondini's Tip #17 in the FAQ I can browse to my prior backups.
The big question is: How can I get Time Machine use the same HD from the Time Capsule (now attached by USB instead of Ethernet) to pick up where it left off making further incremental backups as it had been making for 1.5 years up until the TC's power supply died? I'd like to not have to back the whole thing up separately again and bifurcate the backups.
In Finder I can see a 104.93 GB file titled:
Mjmckay's Mac Mini_0016cba344dd.sparsebundle and dated the date I started using the TC.
Using the Disk Utility I can also see the name and info of the HD as follows:

Right now, TM doesn't see any oldest or latest backups
Are there settings I can change to get it to seamlessly pick up? I think I have seen some references in the user forums to a distinction made by Time Machine between backing up to a Time Capsule (wherein maybe TC is the only "easy" Network Attached Storage destination) with "sparsebundle" files and the way Time Machine backs up to direct, USB 2.0, direct-attached external hard drives (which is what my Time Capsule HD has now become). Or is that the problem at all?
Any one have suggestions?

Time machine-- can't eject backup drive

Hi, everyone.
I have a backup drive attached to time machine. I need to use the firewire port my external drive is plugged into (there is only one) to upload from my video camera. But I it won't let me eject the drive, even though I have gone into Time Machine preferences and turned off the backup. Whenever I try to eject the drive I get en error message that it is in use. What can I do aside from yanking out the cable?
Thanks!

Launch Activity Monitor and see if anything is running that might be using the disk. Spotlight would be my first guess. Spotlight processes start with "md". If that is the case just wait for Spotlight to finish. Don't ever yank a cable without ejecting first. If you get desperate, try shutting down the computer and then disconnect the Time Machine drive.

Time Machine "could not create backup folder" error

I recently changed to a new Time Machine drive (external LaCie Porsche 1TB) connected via USB to my early 2009 iMac running Lion. I set up the drive with a single GUID partition, MacOS Extended (Journaled ) format, and copied my old Time Machine backups over from an older drive via the disk utility restore function. The disk worked fine for a while, then after several backups I get recurring Time machine errors that tell me it cannot create a backup folder. When I run Disk Utility to repair (after turning off Time Machine), it cannot unmount the disk. After a force eject (required because I am told the disk is in use when trying to eject after a Time machine fail), the disk mounts, no problems are found by disk utility, and Time Machine works for awhile. Then more of the same "cannot create backup folder" error. The backups work fine a few times, whether the iMac is put to sleep or not, then the error occurs again. Any suggestions on how to make this work without error and without constantly unmounting/remounting the disk? I had previously used a different, smaller LaCie drive via firewire 800 without any problems ever.
Thanks

I have been wrestling with the same problem for a few weeks.
I eventially solved the problem after determining that the problem is not in the Time Machine program.
It does not seem to exist in Snow Leopard but in Lion and Mountain Lion.
I have several drives on my system: firewire and USB 3.
I observed that one or more of my USB 3 drives become read only after some time even when the Time Machine is off. Firewire and USB flash drives are allright.
I am now running all three USB 3 drives off a Targus USB 3 hub. I got mine from Office Depot.
The power supply for this hub is rated at 4 amperes. Maybe the USB 3 drives need more power.
Some other steps I went through may be of interest:
I updated the firmware on my Wester Digital 1TB drive for the Mac form downloads fron WD sites. I also downloaded the WD Smartware.
However, I found an article that recommended partitioning the drive as journaled case sensitive.
Prior to doing this, the Time Machine would sometimes backup as much as 40 GB even when nothing had been added to my computer. Now backups without activity by me add only a few megabytes.
I noticed that under system profile beginning with 10.7 that the drive storage is shown by category with the sizes listed. This goes on in background all the time. It is possible he USB 2 ports and hubs may not be able to handle this activity.
I have had my computer, a late 2007 iMac with 4 GB of ram, checked by Apple.
This worked for me,

Time Machine can't complete backups after upgrading to Yosemite

I use Time Machine to backup my 500GB MacBook Pro and a 500GB external HD to a 1TB Time Capsule (the laptop and external HD are no where near full). It worked fine until I upgraded my computer to Yosemite. Now I'm get an error message, "Time Machine couldn’t complete the backup to “Time Capsule'. The backup disk needs 425.12 GB for the backup but only 134.74 GB are available. Select a larger backup disk or make the backup smaller by excluding files."
How do I get Time Machine working again (without having to exclude files, of course)? Is there a better way then just wiping out the content of the Time Capsule ad backing up from scratch? Thanks!

Hi there The Zach,

My Time Machine can't see/connect to my NAS Thecus

Hello,
I have NAS Thecus N7700Pro V2.
I got it to be my network storage and I enabled teh AFP in my NAS to be able to use my Time Machine backup.
My current OS is Lion 10.7.5.
When I open teh Time Machine and try to connect it to my NAS it can't see it.
Please advise.
Thanks!

Thanks - that worked - although the solution requires a little updating which was mentioned further down that post. In summary it is now this:
1. Create a sparsebundle image manually on your local system. Open a terminal window and enter:
hdiutil create -size $SIZESPEC -fs HFS+J -type SPARSEBUNDLE -volname "Backup of $MACHINENAME" $MACHINENAME_$MACADDRESS.sparsebundle
Where $SIZESPEC is the size of the backup volume (followed by the lowercase letter g if Gigabytes, e.g. 100g), and $MACHINENAME_$MAC_ADRESS is your Mac's name followed by an underscore and then your Mac's MAC Address (otherwise known as its Ethernet ID; visible in the Network System Preferences panel), but without the colons. So if your Mac is named MyMac, and the Network System Preferences panel lists your Ethernet ID as 00:18:b3:11:84:dd, then you would use MyMac_0018b31184dd for the name of the sparsebundle.
The -size parameter can probably be as large as you want, now that Apple has evidently fixed the sparsebundle issues that were causing all but the most recent backup to be dumped. However, you can also specify a smaller size if you (like me) want to create a hard limit for the amount of space your Time Machine backups will take on your network drive. hdiutil does have a -resize option if you need to utilize that later.
2. Create and set permissions on your network share. Just make sure you have read/write permissions set on whichever SMB/AFP share you're going to dump this to.
3. Copy the sparsebundle to the network share root. Easy enough. Mount your network share and copy it over. I used this Terminal command after the MyBackup share was mounted: cp -r mymachine_0017f2c8426b.sparsebundle /Volumes/MyBackup/. Or just use the regular UI to copy and paste (it worked for me).
