Preventing data corruption with TM and a TC over a wireless connection?

Long story short: I was using TM and a TC via wireless connection to do the usual ~/ backups. My last "manual" backup to a USB hard drive was on June 1.
I decided to wipe the partition to remove a lot of built-up garbage, etc., and reinstall Snow Leopard -- which I did, followed by the 10.6.4 combo update, the usual other patches, and the like. Still reinstalling a thing or two. But when I tried to use Time Machine to restore the things I wanted to keep (about 100 GB of data in all), it was sporadically corrupted and useless. Handfuls of MP3 files that wouldn't play, a good number of PDFs that wouldn't open and were unrecognizable in Preview.app, that sort of thing.
I went back to the June 1 data set and have noticed no issues thus far, but that also means that everything new from June 1 to mid-July was lost.
I would like to still be able to use TM+TC wirelessly, but have it be reliable, so what I'm wondering is this: how can I ensure data integrity when wirelessly backing up my home directory? What can I do to make sure corruption issues like this don't happen again?
I guess the obvious one is to not stop backups in progress by closing the lid or such a thing, but... what else?
Thanks.

I don't mean to be negative here, it's just that with so many wireless interference issues with other networks, cordless phones, security systems, other nearby electronics, etc...the list goes on....I find that it is getting difficult to use the words "wireless" and "reliable" in the same sentence.
If you consider that a business, with important files to back up constantly, would never consider the use of wireless for this function, it might help place things in perspective.
If you are using Time Machine, I think it goes without saying that your first master backup should be using ethernet because the entire computer is being backed up on this pass. Not only will the backup proceed much more quickly, but it will be much more reliable as well. There are no wireless interference issues when you use ethernet.
If you don't need to backup each hour, as Time Machine does, you might want to look at Time Machine Editor to allow you to setup a backup schedule whenever you like. Maybe once a day at 2 or 3 AM when things around the neighborhood on wireless systems have quieted down and the cordless phones are not in use. Or, if you are on the computer quite a bit, maybe twice or three times day. This will minimize the chances of a corrupted backup due to wireless interference.
And a good wireless connection is a must. The "bars" at the top of your computer screen are there basically for show and they tell you nothing about damaging noise that may be present on your network. Post back if you want more info on evaluating your wireless signal quality, which is a combination of the best signal with the lowest noise.
I guess the bottom line is this...the more you can use ethernet (maybe think of your important data as if it were your business files), the better things will be.

You need an Apple TV to be able to wirelessly send pictures etc. from iPhone.
However you can buy an adapter if you want to connect to a TV

HT3887 My iMac won't communicate with my mouse. It keeps saying "wireless connection undiscoverable". This is the first time I have set up my equipment after having a Data Transfer session yesterday. It's a brand new computer. How can I fix this?

How do I get my iMac to communicate with my mouse. It keeps saying "wireless connection not discoverable". Thanks

Hey Jeanette
If you have a USB mouse handy, you can plug it in and use it to navigate to the Bluetooth settings in System Preferences to get the mouse to pair again. There are also troubleshooting steps in the article below for getting the mouse to pair as well.

Data corruption with SSD after hard reset

Hi, I'm using a Mac Mini for a car product and I MUST shut it down each time the hard way, i.e. by cutting the power.
I am perfectly aware that this is definitely NOT the recommended way to shut down OSX because it might lead to data corruption but at the moment there are NO other options. So please don't simply suggest to shut it down the "good way", i.e. via software, because it simply isn't an option.
Now, in the past I did lots of ON/OFF tests with conventional drives and had no problems. Recently I moved to SSD drives and it looks like I get more frequent boot problems (apple logo with the wheel spinning forever). Using DiskWarrior in these cases fixes the problem and repairs the folder structure of the drive. After that the drive boots again.
Given the constraints for the application, i.e. shutdown==powercut, is there any way I can ensure better data integrity? If I disable write caching would that help? Any other trick I could do to make the system more resilient? And finally, are actually SSD more prone to crashes of this kind or was that just a coincidence?
Thanks a lot for the help, I hope some of you has experienced this problem in a similar situation (and found a good solution)
cheers

There are OSX compatible UPSs that send status information to the computer via USB. This enables the computer to do a normal shutdown before the UPS battery runs out. Here's an example of the system preference that will show when a compatible UPS is connected:
<http://www.cyberpowersystems.com/support/faqs/faqOSXUPS.html>
Do you think disabling write caching would help at all?
It might, but the problem may be entirely in the SSD. Do you have journaling enabled on the SSD? That could make a big difference.
Finally, I'm using OCZ Solid 2. Do you have any comment on that or do you recommend something different? I doubt that SLC drives would help in this matter.
You would have to contact the SSD makers and ask them how well they handle power failures. It should be possible to make them no worse than a normal hard drive, but there may be some compromises they have to make for performance reasons.

Date Picker with Previous and Next Year Options

Hi All,
I am implementing a date picker in my application which is tied to an attribute of type PA0001-BEGDA. Date Picker as such works fine but navigating to previous year and Next year options are not available. User has to go month by month to different years if they have to navigate.
Is this the normal behavior of the Date Picker or am I missing something else to get the previous and Next year icons in the Date Picker.
Thanks,
Nagarajan.

hmm..I tried using the select options and it did give the same date picker with the previous and Next navigation icons...The only problem with the select options is that its a single field which has the range and can accept multiple values too...
I tried to figure out how the date picker that we use in the custom application and the one in Select Options differ but no luck...Does this ring any bell?
Thanks,
Nagarajan.

Date Profile with Actions and Deadline Monitoring

Hi Folks ,
I have met an requirement of Actions with Deadline Monitoring of Date Profile . I could able to see Date profile with Day Rules in the standard , But i have met an requirement for very high imp - 2 hrs , High - 4 hrs .... etc. Where in Standard Date Profile i checked all the Date Rules which were in the XML format which describes about Day only.
I m looking for an XML code for Date - DDMMYY & Time Format - HHMMSS and which supports my requirement.
Would be very thankful if any could forward any step for Actions with Date profile with Time depandant.
Thank you
Regards,
Amrita

Hi Amrita,
You take the standard XML code for the date time and copy as per your requirement and give the duration and time unit. Then assign to the action profile and see the action is appearing in transaction.Then go to tcode CRMC_ACTION_JOB and execute that transaction from their. Then the date you want to trigger the mail it will trigger in that time.
Thanx

[SOLVED] Graphic Corruption with 3D and Wine 1.3.8 + Catalyst 10.11

Hello!
I'm getting graphic corruption with 3D games on my Arch Linux configuration using Wine and Catalyst. Tried World of Warcraft (also with opengl rendering) and Guild Wars - graphics look stretched and teared.
Using ATI Mobility Radeon HD4570.
Any ideas? Thanks in advance.

I get same problem with guildwars in fullscreen when entering character select. I have to ctrl-alt-F1 to tty then back to get rid of the garbled graphics. Then my characters vanishes except for their armor/effects. Going into windowed mode stops the garbling of the graphics but the bodyless avatars remain. There is one error stands out in wine output but can't find anything specific to this error that helps.

sum(case category when 'PRIVATE' then sum(core+PP) else 0 end) as 'PRIVATE-Sum',
group by empid,name,country
Note: Following query is good for getting result in one row but i have to put sum calculation with 'THEN' and want result in a row.
SELECT ID, MAX(case when Col1 = 'Yes' then 1 else 0 end) AS Col1,
MAX(case when Col2 = 'Yes' then 1 else 0 end) AS Col2

Could plese check the code,and let meknow what mistake am I doing?
Please help

     if (pos != -1)
               delName = tStr.substring(0, tStr.indexOf(","));
          tStr = tStr.substring(tStr.indexOf(",") + 1 );
               System.out.println("DElName:"+delName);

Does anyone have problems with data usage with att and Iphone5?

Hello, Does anyone have problems with data usage or non usage I should say with Iphone 5 and AT&T?

After 4+ months of dealing with this data usage and battery drain problem that included 3 data captures of my wife's iMac, the trigger for us regarding the problems syncing with iCloud, and 5 hours of logs off my iPhone 6 to be analyzed by Apple engineers that included times my wife's computer was both on and off to demonstrate the difference in data usage and battery drain under those conditions, I can say with very reasonable certainty that the iOS 8.3 and corresponding Mac OS 10.10.3 update has solved the problem.
We have now been running for about 2 weeks and data usage with the iCloud Servers attempting to sync has dropped from a rate of 31 GBs to under 15 MBs per month. Yes, you read it right. We were burning 2000 times as much data doing absolutely nothing important on both of our phones, a 5s and a 6. Just imagine what that does to battery life! The 5s would last about 5 hours and the 6 was dead in less than 14.
The distasteful aspect of this process was how the engineers were quietly fixing the problem at the same time sending messages to my contact person within Apple that were dismissive in nature in the face of indisputable unreasonable results. I must say, this experience with the multiple times the engineers' responses were inappropriate put a little tarnish on the old Apple shine of the ‘It just works’ mantra. This was my first experience in 34 years that caused me to stop recommending Apple products without reservations and with a disclaimer.
Since the update solved the problem, then I can only conclude that there was a logic bug regarding the reaction within the process to the incoming data that was corrected. There was noting short of logging out of iCloud that circumvented the problem for us, Gator5000e and probably many others noted on other threads. I am not trying to imply that this is the cause of everyones battery use problem, but it is reasonable that it was a cause for many.

I have a new ipad2, also an ipad1, with a gateway laptop. I have wireless router with windstream. Able to access my wireless connection on ipad1 and laptop, but can't on ipad2. Will say connected, but get message saying not connected to internet on Safari

I got an ipad 2 today. Already have an ipad 1 and gateway laptop. Have wireless internet with windstream. I have internet connection on ipad 1 and laptop, but can't connect to internet on ipad2. It says i'm connected, but when accessing Safari, it says not connected to internet. Tried unplugging router and resetting already, still not working. Thanks for the help.

Thank you for your response.
I did try turning off the firewall, and reducing all the security levels to a minimum (under Control Panel>Internet Options). Also, I'm using a direct cable from my m/c to the Airport Extreme. But nothing helps. Due to the usage pattern in my family, using the MacBook for configuring the network is not optimal, hence my struggle to do it on my Windows desktop. But if that is the only way to go I suppose I'll have to.
Subsequent to posting my query, I discovered that Apple had not singled me out, and many others with a Win OS face this problem, too. I would have thought Apple would do a proper job of testing before putting up the Windows version of Airport Utlity on their site.
But thanks again. Much appreciate it.

HT201068 Updated Remote Desktop Admin 3.8 and now my Time Capsule wireless connection is slow

I recently updated to Remote Desktop Admin 3.8 and since then, I have had issues with the wireless connection from my Time Capsule.
1) I reset modem and had no change. 2) I then plugged the ethernet directly into my Mac and the connection was great so it's not the service or modem.
3) I hard reset the TC and when it came back, the speed was good but went back down after a few minutes. 4) Plugged ethernet directly into Mac and again, the speed was great so it is definitely the TC.
Would love some help resolving this. Hoping I don't have to get a new wireless router. Maybe the TC is too old? I purchased it in 2009 or 2010/ Current version 7.6.4

Most home routers running 24/7 are good for about 3years.. your TC has now managed to survive 6 years.. it is well and truly time for a replacement. Simple fact is, it should be dead by now.. so you are living on borrowed time whatever happens.
Why RDA would slow the wireless I am not sure..
Are you running Yosemite.. ?? I tend to point the finger at the OS rather than an application.. mind you if the amount of data going back and forth has increased.. what appears to be slower wireless might actually be something else.
Apple has reasonable wireless analyser built into the OS since mountain lion.. it is well worth using.
http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/
I recommend doing a few things like short names, no spaces pure alphanumeric for everything in networks. Passwords also must comply. Apple made changes to network protocols since Mavericks but did not fix the names being recommended in the airport utility.. and still haven't which break their own rules.
And fix names for bands differently so you can force the connection.. plus setting channels.
However in a unit of that age.. it will have pretty weak 5ghz and that is what is important for high speed wireless.. Apple have hindered 2.4ghz since forever.
