Aug 1, 2013 5:26 AM in response to backspacesby namurphy,backspaces - I am curious about what solution worked?
-
Aug 1, 2013 9:46 AM in response to namurphyby backspaces,This is the solution I tried and it did work just fine.
I have a synology NAS, and my laptop and mini backup to it, both running Lion latest, over wifi connected via airport extreme.
Good luck! Let us know if you run into trouble.

Aug 21, 2013 6:31 PM in response to July7Kiss1995by AvalonNYC,I nominate this as the worst Apple error message ever! If the backup is corrupt, why not tell the user that? Stop pussyfooting around! "Your Time Machine backups are corrupt and probably useless. Time Machine must create a new backup for you."

Aug 21, 2013 6:53 PM in response to AvalonNYCby Pondini,Agreed!
However, posting here won't help -- these forums are for user-to-user help only; they're rarely, if ever, monitored by Apple for technical content.
But do add your voice here: http://www.apple.com/feedback/timemachine.html

Aug 21, 2013 8:05 PM in response to AvalonNYCby backspaces,Please, just use the great instructions garth.org offers above .. and don't forget the tipjar!
Yes it's sad that Apple has a problem. Yes it's sad they are Draconian. Yes it's good we have a community that has given us a fine solution.

Oct 19, 2013 2:11 PM in response to July7Kiss1995by gngdutch,I experienced this problem the first time yesterday. And my TM history has now been deleted.
As I don't use TM as my primary backup this did not concern me too much until I recieved the message again today and started searching for why TM to want to keep deleting itself.
MBP retina 10.8.5
TM on (LAN) Synology DS410
I have used the NAS for TM for a number of years without a problem for a number of laptops and mini's.
Have fallen back on TM many, many times in the past when upgrading hardware, reinstalling after a motherboard failure and after the occasional accidental deletion of work in progress - have been impressed and very happy at how well it has worked. (from a TC in the past before I got the DS410)
So . . . rather disappointed to read that this error could herald a future of unreliable TM backups likely caused by the NAS.
The error appeared after I had (coincidentlly) been working on the DS - updating packages, setting up surveillance station and yes I installed the 'Antivirus Essential" for the first time. . . so I am guessing that this is most likely the cause given some earlier comments . . .
I have uninstalled the AE package, am wondering if I need to go through the steps to fix the sparsebundle or will a new TM backup be OK from now on ?

Oct 19, 2013 2:41 PM in response to gngdutchby m3ki,I have a synology DS1812 and as I mentioned earilier. This TM behaviour was due to data scrubbing while TM backup was running. So if anything on synology is accessing and/or modifying sparsebundle file ie data scrubbing(optimizing volume) on synology while backup is running boom you will have this problem.
This can happen if:
Your have just added a new drive to synology. -- confirmed
You started manual data scrubbing on your volume.-- confirmed
You're running smart test? (not sure if this does it)
Above scenarios cause those problems for me.
Solutions:
Disable TM backup while adding a new drive and/or doing scrubbing. You can use http://www.klieme.com/TimeMachineScheduler.html or just stop it.

Oct 19, 2013 3:22 PM in response to m3kiby backspaces,I have both an Air (laptop, often open/closed) and a Mini (always on). Both use Synology NAS. The Air fails periodically, I'd say every two months. The Mini has never had that problem. Both run OSX 10.7.5.
I believe Apple cannot fix it, they are poor at remote file systems in general, even tho they are based on a Mach kernel. Hard to believe, but you gotta remember their market is more the designer, and UI world, and often are draconian in terms of listening to user's technical difficulties.

Oct 20, 2013 2:25 PM in response to steve.mccormick2by backspaces,Just to be clear: Is this mainly a laptop problem, .. i.e. are the predominant failures wireless NAS to laptops, not allways-on desktops/minis, either via NAS or directly connected?
This is the case for me. Directly connected, no problem. Wireless NAS, only a problem with my Air not my Mini.

Oct 21, 2013 6:08 AM in response to backspacesby namurphy,No, I do not think it is only a laptop issue - I have an iMac and have the same problem. I do back up wirelessly, however.
I disabled Carbonite and have not received the error message in a few months. I disabled Carbonite because Apple support (some type of upper level support), told me to uninstall Carbonite, Parallels, and another program. I said it was not possible for me to uninstall Parallels. So, they closed my support case.
I decided to disable Carbonite to see if that solved it. It seems to have solved it, but I liked having several different backups. Not at all happy with having to disable a program I have used for 10 years. Carbonite was working just fine - with TM - on the iMac for at least 2 years. Before that - there were no issues with MBP, Mini. All running wirelessly

Oct 21, 2013 8:58 AM in response to namurphyby backspaces,That's sad, IMHO. Carbonite (and the other backup services) are quite nice. I use dropbox which as well as sync is a nice backup. I also use Arq, which does a great job of backing up to Amazon, either S3 or the archival, dirt cheap storage. I also use Google Drive and Amazon Cloud, they're quite useful too. I've also considered one of the others like Carbonite, all of which get rave reviews amongst the tech community here in Santa Fe.
So in our thrilling attempt at diagnosing the problem, it seems like Apple suspects windcows emulators? I can kinda understand that. Do you have TM backup the windows partition/file? Possibly that's where the cat-fight occurs.
My backup strategy is to have several replications of my data, simply because Apple is technically challanged in the kernel and systems level. I speak from experience, I built the first Mac (printing software, laser writer).
As painful as this problem is, its is rather fascinating to see if we can come up with at least a few suspicious common scenarios.

Oct 21, 2013 10:33 AM in response to namurphyby gngdutch,No Carbonite, and no Parallels, just using the DS410 NAS for TM, which has worked great for years until the day (literally) that I activated the Virus package from Synology - uninstalling the package and recreating the TM backup 'seems' to have worked as TM is backing up again without error.
Time will tell.
One additional, maybe related (maybe not) error that also popped up very recently is that my MBP keeps changing its name (adding sequential numbers) after giving an error message that a computer of the same name is already present on the network (which of course there isn't). I haven't had the time to try and fathom out what is going on here, but I did notice that my TM backup has also aquired this automatically updated name MacBook Pro (10) - Am wondering if the MBP name change could be a reason why TM requests to reverify as there is no longer a match in naming ?
I will see what happens if and when the MBP name changes (it is a random occurence) - curious if anyone else experiencing this TM verify issue also has the automatic name changing ghost ?
I am still inclined to think that it is more likely the Synology Virus Essentials package . . .

Oct 21, 2013 10:55 AM in response to gngdutchby m3ki,It really seems to me it's linked to whatever is accessing bundle file.
Do a test: exclude the share that contains TM bundle file from antivirus and or any indexing software packages on synology.
If there is nothing touching that file there is nothing to break.

Oct 26, 2013 12:59 PM in response to backspacesby steve.mccormick2,Just to be clear. This issue has occurred on my iMac and MBP. It is not isolated to laptops. Although it occurs more often on the MBP.
I am not using Parallels or VMWare.
