AWesome post!!! this should be a sticky!!!

James From Qnap solved my problem and now everything is ok.

The only thing to do is :

connect with ssh
ssh admin@youripadress
go to directory : share/TMbackup
then remove this files
[/share/TMBackup] # rm .com.apple.timemachine.supported
[/share/TMBackup] # rm -rf .AppleDB/

Sorry for my bad English and tanks again dear James

Sorry, I don´t want to be unthankful but could you give us a way so the normal MacUser could understand what to do exactly?
First of all: Were, how and what to connect with ssh??? I mean in finder or at the NAS directly….

Besides that, does anybody know what is done exactly by removing those files? Is just the error message removed or the cause of the message?

Thanks in advance!

Hi to all,

I would like to post a question without open up a new thread as I guess that's already the right one for asking about my issue.
My brother has recently bought a new Mac and I wish to back up his datas into qnap's TimeMachine application. Strangely, I don't manage to connect the client TM application (the MAC computer) to the server one and I'm not able to understand the reasons. I've no problem with another MAC computer which belong to my second brother who can get connected easily. So a doubt has popped up about the impossibility of backing up multiple MAC devices into the NAS or, most likely, the due to configure some files properly.

Can you give me some tips of how to solve this problem?

Thank you all in advance!

I tried the steps above, but still can't connect to the TimeMachine drive. Any help greatly appreciated.

To use an ssh connection from a mac, the easiest is to use the terminal: http://mac.appstorm.net/how-to/utilitie ... he-basics/

Hi all,

the backup of my Macbook Pro (currently Mac OS X Maverick 10.9.5) on my QNAP NAS (currently TS 212P with QTS 4.1.1; before TS-110 with pre-QTS firmware) with Time Machine has troubled me for a long time, so I though I give it another try in this forum:

At the moment, it does work in general, but is painfully slow. For example, backing up 50 MB of data takes about 40 minutes (see below), while manually transferring a similar amount of data to the same NAS drive takes only of few seconds (with both SMB or AFP). So clearly, something is very wrong here, either with the NAS or the Mac.

Digging into the system log, I found the following:

Now apart from the rather slow process, there seems to be problems with the mounting or rather renaming of the TimeMachine share (see entry at 19:55:33). Any idea, why TM wants to rename this at all and why it would fail? Moreover, TM seems to find a workaround by mounting the same backup set a second time (see entry at 19:56:30). Could this lead to the very poor performance?

The above pattern, i.e. the failure to move/rename followed by a second mount of the backup volume, appears with every backup (manual and automatic). I also found some other problems in the log, however, they were not consistent:

Code: Select all

22.10.14 19:34:12,141 com.apple.backupd[8841]: Error: (5) getxattr for key:com.apple.backupd.SnapshotState path:/Volumes/Time Machine-Backups 2/Backups.backupdb/Mathias NeumuÃàllers MacBook Pro/2014-09-30-184548

Lastly, to give you a fuller picture, I should also mention that in the past, TM on occasions reported a corrupted backup set. I've tried the various suggestions on this board and others to fix the corrupted sets, but to no avail. However, I am starting to believe that this is rather a consequence of the slow backup speed than its cause, caused by incomplete backup runs.

Any insight into these issues would be really appreciated!

TimeMachine on QNAP: Unusable

I have followed the hints to remove the .AppleDB, .AppleDoulble etc. and I was successful with restarting AFP.

By the way: How many months will it take until QNAP pushes an update?

However, as in the about 6 cases in the last 2 or 3 years, touching TimeMachine deletes my entire TimeMachine backup without even asking!

Conclusion: This is not professional AT ALL - and I'm reverting to external USB disks. There, I am able to have a backup back to 2011. Never with QNAP.

[sonicflight]

For all that I spent on this unit and the 'professional' grade quality it is supposed to have, why isn't this issue fixed yet by QNAP..? This is totally horrible support and nowhere near the expectations that QNAP establishes for their product and software. Isn't anyone else frustrated on this.? This is just unacceptable..!

[datatrack]

Thanks for this post. It is an important information about time machine.

Great tip notshy!

Hey guys,

I just enabled TimeMachine backup on my TS-431+ with the latest firmware 4.1.4 2015/05/22 but the disk doesn't show on my MacBook pro.
I connected via ssh to the NAS and looked into the /share/TMBackup folder: nothing in there...

Any suggestions what I can do?

Thanks
Soko

I just enabled TimeMachine backup on my TS-431+ with the latest firmware 4.1.4 2015/05/22 but the disk doesn't show on my MacBook pro.

It can take a moment until the Bonjour announcements show up.

While both should be enabled and started with the Time MAchine configuration, lets check it:

Is Bonjour enabled? Control Panel -> Network Services -> Service Discovery -> [Bonjour]

[~] # ps -ef | grep avahi
6556 guest 1208 S avahi-daemon: running [TS-212.local]
...

Is AFP with DHX2 enabled and running? Control Panel -> Network Services -> Win/Mac/NFS -> [Apple Networking]

[~] # ps -ef | grep afp
8671 admin 568 S /usr/local/sbin/cnid_metad -F /etc/afp.conf
9031 admin 648 S /usr/local/sbin/afpd -F /etc/afp.conf -p /var/afpd3.pid

When things are really bad, the (wireless?) network infrastructure might block or filter the announcements.

[sokofromnz]

I restarted and enabled/disabled the whole thing a couple of times and it showed up.
Haven't checked it for a while though as I'm not using my MacBook regularely.
Thx for the help though! If I'm running into troubles again I check your things first

James From Qnap solved my problem and now everything is ok.

The only thing to do is :

connect with ssh
ssh admin@youripadress
go to directory : share/TMbackup
then remove this files
[/share/TMBackup] # rm .com.apple.timemachine.supported
[/share/TMBackup] # rm -rf .AppleDB/

Sorry for my bad English and tanks again dear James

Thank you for this post. I continuously got the following error, and removing the .AppleDB solved it for me.

Code: Select all

I remember this... it was a PITA until I changed backup units to a DS415+. Then it just worked... go figure.
