Time Machine on a NAS - Avoiding "Time Machine completed a verification of your backups....."
I use Time Machine to wirelessly backup my MBA to a Buffalo NAS. It will work fine for weeks or months, then I will see the dreaded "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.” error. Of course this means I lose all my backups.
I have researched this pretty thoroughly and I know that using TM with a NAS has some risk. But I am hoping to not have to resort to dragging out a USB drive everytime (daily) I want to do a backup.
Can anyone share sucess stories of how they make TM work reliably with a NAS? Is it a Buffalo problem and a different NAS works better? I know the majority of TM users have no problems. What am I doing wrong?
Thanks.
I have a Synology 1511+ and had the same issue. Except my backups would only corrupt every month or two.
After lots of searching I found the issue is backing up over wifi to the NAS. I found the solution to this was to install a small app: Time Machine Scheduler (free).
It can be found here: http://www.klieme.com/TimeMachineScheduler.html
All you need to do is install, and set backups only to run over Ethernet. Works great for me as I use my mac 50/50 between my workstation and wirelessly around the house. Haven't had an issue since.

I keep getting this error on my new Macbook Pro w/ Retina.
"Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you."
Connected to a wifi network and QNAP storage system. There are 5 computers on this network, and each backs up just fine. The issue is isolated to this one machine.
This error shows up every week or so.A third-party NAS is unsuitable for use with Time Machine, especially if it's your only backup. I know this isn't the answer you want. I know Time Machine accepts the NAS as a backup destination. I know that the manufacturer says the device will work with Time Machine, and I also know that it usually seems to work. Except when you try to restore, and find that you can't.
Apple has published a specification for network devices that work with Time Machine. None of the third-party NAS vendors, as far as I know, meets that specification. They all use the incomplete, obsolete Netatalk implementation of Apple Filing Protocol.
If you want network backup, use as the destination either an Apple Time Capsule or an external storage device connected to another Mac or to an 802.11ac AirPort base station. Only the 802.11ac base stations support Time Machine, not any older model.
Otherwise, don't use Time Machine at all. There are other ways to back up, though none of them is anywhere near as efficient or as well integrated with OS X. I don't have a specific recommendation.
If you're determined to keep using the NAS with Time Machine, your only recourse for any problems that result is to the manufacturer (which will blame Apple, or you, or anyone but itself.) -

Why do I get "Time Machine completed a verification of your backups on..."
Any idea why I keep getting 'Time Machine completed a verification of your backups on “MyBookLiveDuo”. To improve reliability, Time Machine must create a new backup for you." ? It's just started happening. Running 10.8.2 on two laptops. One is fine backing up the other keeps showing this error. Both versions of the OS are identical. Same wireless network, same Raid back-up, same tiem zone etc. Any ideas? It takes hours to wipe and start again, and really defeats the idea of Time Machine.
The disk images on which the backup data is stored are being corrupted. Backing up to a network device other than a Time Capsule or a Mac is unsupported by Apple. You're completely dependent on the device vendor if something goes wrong, and the vendor will blame Apple.
I suggest you start backing up to a locally-attached external hard drive, preferably more than one, or to a supported network device. If you don't want to do that, use a backup tool other than Time Machine. -

I just wanted to collect all my messages since oct 16th. under one roof. I have spent too much time with this problem already, will NOT edit this the way I should. It REALLY bugs me that Apple doesn't acknowlege it - would make life easier knowing that they are working on it.
I have the same problem. It all started around Oct. 13th when my old 13'' MacBook was doing it's last backup just before I got my current 15'' Pro. It was running up-to-date SnowLeopard, and have 1TB TimeCapsule (1st generation).
Now I have had this same problem every two weeks running Lion in my new MBP.
This does not seems to be just Lion-related, or because of lack of space - my HD was 320MB, now 750MB (350MB used).
TM will erase the disk in this particular case, and you will loose all the data history!!!
You should make a backup with CCC or similar on a separate disk to be on safe side.
I think that there will be a fix for this problem, we are not the only ones complaning.
After more research I ended up with two options: either the TC HD is at the end of it's 4 year life OR Lion TM settings > options > lock documents 2 weeks after last edit is somehow behind this problem. I unchecked this setting and will see after two weeks...
Meanwhile, fingers crossed.
SAME BIG PROBLEMS HERE TOO. JUST GOT A NEW 2TB TC bacause thought that my 4y. old 1st gen is kaput - but the problem returned just after 5 days of usage. And the newest airport firmware update did not help the situation at all...
Disk Utility verified TC disk OK, new MBP running Lion disk ok as well.
Tried about everything with my old MB with SnowLeopard.
I mean I have tried really everything since the problem occurred mid-september - new MBP, new OSX (Lion this time), new TC THIS WEEK, started fresh from the very beginning but the problem still exists.
I have no other software in my mac but from Mac App Store + Nikon + Adobe.
A virus? Others have it too?
Studied all day today and tried many options including ethernet / wireless settings (FYI: found out also that in Airport Utility alt-key brings the missin options in setting up wireless- and radio modes - confusing since no mention of this in the manuals).
There is a firmware/OSX - problem and it bugs me that Apple doesn't acknowlege it - would make life easier knowing that they are working on it.
Too many people are having these problems, and also I lost a couple of days of work while solving this on my own.
Here we are solving this mess as well. My 1st gen TimeCapsule began to work odd two months ago, needed to do fresh backups every week or two. Finally got a new one this week. Seemed to work fine first, but today a complete stop with my network. Problems occured not immediately after the firmware 7.6 update though. Seems that my iWork backups are a bit of a mess too since Pages keeps showing an unwanted photo in a written article after deleteting it from there...
I have my new TC 2TB as a base station downstairs + express extending to upstairs study + express joining for AirTunes (+ the old TC to play with). Lion and Airport Utility up-to-date.
Got also new MBP two months ago.
First thought that Lion is the problem, then that old TC is the problem - seems like APPLE is the problem...
BTW - DID YOU KNOW THAT YOU NEED TO HIT ALT-KEY TO SEE ALL OPTIONS FOR WIRELESS MODE AND RADIO MODE??? AND THAT SOMETIMES IPHONE AIRPORT UTILITY SHOWS THOSE OPTIONS, SOMETIMES NOT... sort of hard to figure that out without a mention in the instructions...Unfortunately, the message pretty much says it all.
What it does not tell you is that your Time Machine backups are corrupted and Time Machine cannot repair them, so it wants to delete your entire backup file and start with a new one.
I'm afraid that AppleCare will tell you the same thing, but it's worth checking with them to see if there are any new developments in this regard for this puzzling issue which affects a small percentage of users.
Please post back on your findings if you pickup some additional useful information when you speak to Apple. -

Time Machine completed a verification... must create new backup??
I just saw a notice on my headless MacMini that "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. Click "Backup Later" to be reminded tomorrow.
That sounds ominously like it should have said "Time machine encountered an error, and you're going to lose all your history when I start a new backup for you, but you really have no choice other than to delay the pain for a day".
This is a relatively new 2Tb capsule, model A1409, from 9/7/11, which is backing up a Mac Mini (new as of April) and a new MacBook Pro (as of May).
Is there any way not to lose that backup history? Any way to debug what happened so I can take steps to make sure it doesn't happen again?
Thanks!
SteveBob,
After re-reading my initial reply, please do NOT think I was saying that "you" didn't answer my question about what happened.
I was trying to imply that sunspots and cosmic rays are indeed sometimes part of our life in IT, and that I was just going to "accept it, lose my history, and go on".
I do truly appreciate help, and would have hated to have you think that was directed "at" your reply...

Time machine always propose a new fresh backup
Hi all,
I am running an iMac 21.5" Late 2012, with an Intel Core i5 at 2,7 GHz, 8Gb RAM. I have recently (some months) moved from Mavericks to Yosemite (by the way, experimenting a general slow down is the system, I have brought my mac to an Apple Store and, after their checks, they told me that the computer i perfectly fine...) and since then I am having problems with Time Machine backups. After the first backup, time machine correctly performs following backups for a while and then (say, generally after a couple of days of seemingly correct functioning) asks me for a fresh backup as the verification of the actual backup seems to be not not reliable enough.
Technically, the message I get is the following:
Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.
What I can't really understand is why is this happening so frequently... It is quite boring to have my machine backing-up a large amount of data (I have a 1TB HDD connected to an Airport Extreme, to which my mac connects via wi-fi) almost every two days...
Let me just add that I was NOT having such problems when running Mavericks on the very same iMac...
Is there any reported problem of this kind? What does it depend from? Is there any possible solution to this?
Any help would be very welcome!
Thanx, best regards

I recently starting receiving the error message "Time Machine couldn't complete the backup to... An erro occurred while copying files. The problem may be temporary. If the problem persists, use Disk Utility to repair your backup disk. I have had no problems backing up my MacBook Pro 2011 to my Western Digital My Book Live through a Linksys EA4500 router until recently. I've made no major changes. I've ran a diagnosis on my back up drive with no problems. The Time Machine back up starts, but about after about 5 to 10 minutes I get the error message. I can see the shared drive in Finder. The light on the drive blinks while it starts the back up. I can see the shared folders on the networked drive. The backup process starts but for some reason it just stops. Can anyone help?
You can't repair a network volume in Disk Utility.
Backing up to a third-party NAS with Time Machine is risky, and unacceptably risky if it's your only backup. I know this isn't the answer you want, and I also know that the manufacturer says the device will work with Time Machine, and that it usually seems to work. Except when you try to restore, and find that you can't.
If you want network backup with Time Machine, use as the destination either an Apple Time Capsule or an external hard drive connected to another Mac or to an 802.11ac AirPort base station. Only the 802.11ac base stations support Time Machine, not any older model.

Using Time Machine on a network disk getting 'backup disk not available'
I just installed SL on a brand new MBP. on my last MBP I used to backup to a network volume and htis worked fine (also under SL), and my other MBP is also still backing up fine. however I am unable to get it to work on the new one.
Tried to connect the HD to the MBP and make a backup direct, than move the HD to the server in the network and try to connect, TM refuses to backup to the mounted disk.
I followed these instructions with the same result.

any tips ideas or tricks?

What are you backing-up to?
A FW HD connected connected to my MM server hanging in my network
The link in your first post is talking about making TM back up to an unsupported NAS device, but you also mention connecting it "directly" to your Mac, as if it's an external USB or FireWire HD.
Yes to test, I connected the HD direct to my MBP and it did a Backup. Some forums suggest doing this if you can not make a BU over a network to start with. Than connect it in the network and select it as the TM BU, and it works. However, not in my case.
If it is a NAS, especially an unsupported one, it seems to be some sort of problem with the programming on it, or the procedure to connect to it. You'll likely do better contacting the maker.
As said I think the HD is fine, other machines back up to it since ± 18 months with no problems. It must be a setup problem or the likes.
Also be aware that if you have to use that "unsupported devices" Terminal command, you may not be able to do a full system restore from that device. The only way to do one is to boot from your OSX Install disc, and use the installer utility on it, but since you can't apply that command there, it may not recognize your backups.
Worked fine in the past. Did test this in the beginning. -
Can anyone tell me what this Time Machine error means? The network backup disk does not support the required AFP features?
AFP - Apple Filing Protocol
The Network Attached Storage (NAS) that you are pointing Time Machine at does not have the features needed by Time Machine in order to do its Thing. Time Machine needs some specific features that are not typically available on generic networked storage devices.
There are manufactures that support the Mac OS X HFS+ file system formats and implement all the needed AFP protocol packets necessary so that they can be used with Time Machine, but apparently yours does not.
If you are not using a networked mounted volume for Time Machine, then more information will be needed about your Time Machine setup. -
How to set up time machine so it can view old backup after renewal of user rights ?
I am newbie in the mac world but I am very happy to use the devices I have.
I just both and setup time capsule and did firt initial backup with time machine into account I have setup on the TC. But after while I was not able to view my user folder, so I resetup the user rights.
But now when I turn on time machine, I say that I didnt perform initial backup. In finder I am able to see and acces my folder on TC now and there is also a file with backup with name Václav - Mac mini.sparsebundle just in the root of my user folder on TC.
Can you please help me how to tell TM, that there is a initial backup that can be used for other incremental backups in the future ?
Thanks for your help.
Vaclav.I did that. But and then reopen TM but still I dont see backup performed any suggestions ?
"Inherit" a backup
Copy the following after the prompt, and leave a space, but do not press Return yet:
sudo tmutil inheritbackup
If your backups are on an external HD, locate and open the drive in the Finder window. At the top level of the drive is a Backups.backupdb folder containing a folder named for your old Mac, per the sample. This is what you want the new Mac to "inherit." Drag that folder to the Terminal window.
(If your backups are on a Time Capsule, locate the sparse bundle containing the backups for your old Mac via the Finder, and drag it to the Terminal window): -
Can I choose which backup for Time Machine to use if I have backups from two macs on one drive?
I have Time Machine backup on an external drive. I want to mirgrate all my files onto the new Mac Pro but migration is getting hung up and cant find the drive. Can I set up Time Machine for the new mac on this same drive and then select the old macs backup from within Time Machine?
Most likely, some folders were excluded from your backups as the result of a failed or aborted software installation.
Starting from a clean installation of OS X, set up a new administrator account and log in. Enter Time Machine and press the key combination shift-command-C. The front window will show all mounted volumes. All snapshots should now be accessible.* Select the one you want and navigate to your home folder (in the Users folder at the top level of the old startup volume.)
You should now be able to restore your user data. I suggest you do this in two stages. Quit all applications except the Finder before you begin.
Restore all the visible items at the top level of your home folder.
Hold down the option key and select Go ▹ Library from the Finder menu bar. Enter Time Machine and restore all items in the Library folder. Log out and log back in as soon as the restore is complete.
Any other invisible folders or files at the top level of your home folder that you want to preserve will have to be restored separately. For most users, that isn't necessary.
You'll have to reinstall all third-party applications from scratch, or restore them from another kind of backup, if you have one.
You'll have another problem if this is a new computer, or if you erased the startup volume: The next time you back up, Time Machine won't recognize any files as being the same as they were before, and will make a full copy of all files. There might not be enough space on one or more of your backup volumes for that. There are different ways of dealing with that situation, depending on your needs. The easiest way is to set your backup drives aside, if possible, until you're sure you'll no longer need the data on them, then erase them and start over. Meanwhile start a new backup on one or more empty storage devices. If that solution isn't workable for you, ask for instructions.
*If you don't see any snapshots in Time Machine, exit the time-travel view and then hold down the option key while selecting
Browse Other Backup Disks...
from the Time Machine menu, which has an icon that looks like a clock running backwards. Select the backups of your computer by its previous name. If you don't have the Time Machine menu, open the Time Machine preference pane in System Preferences and check the box marked
