(No sarcasm, I'm curious about these snap solutions in general. Though I am really down on Dell for what turned out to be a brain-damaged laptop I got for my wife.)
Well, you can't really make a judgement about a company's enterprise products based on an experience with their consumer products.What if it came from what they call a business products catalog? They intermingle laptops with servers.
Don't know, in general. I do know that for Dell there is a distinct difference between their decidedly consumer laptops (Inspiron) and their "business" Lattitude series. I know that at my last job we had a lot of rock solid HP equipment (servers and SAN) - vs. an HP laptop I had that was trouble from Day One. I'm sure there is a point in desktops and laptops the line can get blurred, but in the case of the OP, he was no where near that fuzzy line.

Time Machine backup created on Mac with a large hard disk. What happens when restore to MacBook Air with small SSD drive?

What if a Time Machine backup was created on a Mac with a large hard disk, e.g. 500GB iMac - and I buy a new MacBook Air with a small SSD hard disk e.g 128GB. What happens when I need to use the larger Time Machine file to set up the new MacBook Air? What happens to all those files that can't fit on the smaller SSD drive?

It is not the HD size, but rather the size of the data it contains. If you right-click your 500GB drive and select "Get Info" you can see how much is actually being used.
Naturally if you are using more space than the new drive has, then you have to make some choices about what you want to keep and what you want to keep archived.
I don't know what options are available but you may simply have to do a manual restore of files you want, in groups.

What happens when I restore data to a non-factory set iPhone?

Okay, another iCloud question. What I did was basically delete a game, start a new one, and now I want my old game back (saved to ICloud). What happens when I restore full data to a non-factory set iPhone? Will it overwrite current data? Will it delete everything? I just want to know, I'm such an iOS noob. :-/

A restore is all or nothing.
If a backup is restored to the device, ALL data currently on the device is wiped and replaced with the data from the backup.
Restoring a backup to get one saved game back seems rather extreme and silly.

What happens when Time Machine starts to fill up a drive?

Using Time Machine on a partitioned External HD has been an absolute snap! I love the app. My main disappointment with it is that it has no literature on HOW it works, and no real ways for me to set different controls for it other than on and off.
My question is that what happens when a drive starts to get full? I have about 30 gigs left on the partition, and I am wondering what Time Machine is going to do. Does it just delete the oldest material, or does it simply fill up and tell me to look at everything on there and decide to clear it all off. I hate that I don't know what will happen.
-Jon

From what I've read (I've not gotten a drive full so I can't speak from experience), when the TM drive gets full, it will notify you that it's going to start deleting the oldest backups to make space for the new ones. This general behavior is mentioned in the Mac Help for Time Machine, though it makes no mention about notifying you before it deletes the old backups, so I'm not sure about that part.

Database in backup mode

Hi Guys,
If I put my database in backup mode and perform the backup (hotbackup/online) of the database.
When I need to do restoration, do I need any archive logs at all? (not necessary to recover up to point in time) Can i just restore the datafiles and do a alter database open resetlogs?
Will the database be inconsistent and can't startup without applying any archive logs at all? as the datatabase is not shutdown when doing the backup.
thanks

Will the database be inconsistent and can't startup without applying any archive logs at all? as the datatabase is not shutdown when doing the backup.Yep.
That said, use RMAN to do the same thing. It would be much better to use it than using the backup mode .

VDI3: what happens when the Primary VDI core fails?

A potential customer asked me this and I did not really know how to answer the question ... sorry if this was asked before. So here we go:
What happens when and if the Primary VDI core fails? Will the entire VDI3 setup go down? Will running sessions be lost? And how do you fix that?
I found this page:
http://wikis.sun.com/display/VDI3/MySQL+Cluster+Reconfiguration+Scenarios
So I assume the "Non-VDI host ==> Primary Management Host" scenario is what would need to be done?
http://wikis.sun.com/display/VDI3/MySQL+Cluster+Reconfiguration+Scenarios#MySQLClusterReconfigurationScenarios-NonVdiToPrimary
If this is correct then this would answer the "how do you fix that?" part. OK then.
But still I'd welcome if anyone could explain what exactly would happen when and if a Primary VDI core fails. The customer's opinion on this is that they are a "single point of failure" because the Primary VDI host is not redundant (as opposed to the 2 x Secondary VDI cores) ... So, is this assumption correct or not?
Thanks in advance.

Hi,
Assuming you have 3 VDI core hosts. One of them is the primary. And the primary goes down. So what happens then:
* The underlying database is still running on the remaining hosts
* All desktop sessions are still running on the remaining hosts
* New session requests will be handled by the remaining hosts.
* All desktops are still running on the virtualization hosts.
So in essence, your VDI cluster is still healthy. The operation is just impacted in this way:
* You can't add new VDI core hosts
* You can't change the configuration of the Sun Ray server failover group
* A failure of another VDI core host (data node) will result into a complete outage of the underlying database
You should bring up the primary again as soon as possible in order to gain failover capabilities again.

What happens when the Time Machine drive is full?

I'm on my second iMac. My first one (G5, 1984) died, and I replaced it early 2010 with an Intel mac. The transition when exceedingly well largely due to Time Machine. I just hooked the Time Machine drive to the new system, and I was soon back up running!
My home folder has 70GB of data. The Macintosh drive has 105GB of data and 395GB free. The Time Machine drive has 220GB used and 30GB free.
1. What happens when the Time Machine drive is full?
2. Do I have control over what backups get deleted?
3. If lightning strikes twice, will I still be able to restore my Intel mac like my G5 mac, even if backups get deleted?
4. Is there anyway to control what backups/backup files get deleted?
5. Any other thoughts?
Thanks.

i have deleted the time machine folders and they are now in my trash. when i try to secure empty my trash it will delete everything but the t/m folders. how do i delete them?
Do you mean all of them? The entire Backups.backupdb folder?
That's a large mess. First, even a normal delete will take a very long time, as there are probably hundreds of thousands, or even millions, of files. Your best bet by far is to simply erase them with Disk Utility -- that will only take a few moments. If your TM drive has a single partition, see #1 in [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html]. If there are other partition(s) on the drive, see #2 there.
If not, and you only deleted some of the folders, you have a different, worse problem. Unfortunately, Apple doesn't do a very good job of warning folks: +*Never move, change, or delete anything in your backups via the Finder or Terminal.+*
You shouldn't have to delete backups at all, since Time Machine will do that automatically when the disk/partition gets full. But you can do it without harm via Time Machine. See #12 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
A normal delete will take a very long time, as there are probably tens or hundreds of thousands of items, each of which must be individually deleted. A secure delete will take much, much longer, as each deleted file must be overwritten with zeros.

What happens when the iphone app won't open on iphone 4?

what happens when the phone does not open and automatically shuts down the phone?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

What happens when error record

Hi ABAP Gurus,
Iam phaneendra can anybody explain in detail
what happens when there is an error record exist while updating a session in session method and in call transaction.
ie, out of 10 records 7th one is error let it be then what happens to 6 redords that 7th record and 8th 9th 10th records.
and also what is assychronous and synchronous
process .thatly in updation.
good answers( helpful answers must be rewarded)
regards,
phaneendra.

Hi,
In Session Method all the 9 records will be updated except the &7th record(error record). u can get the error information in SM35.
In call tranasction method it depends upon the mode(A,N,E). In all screen mode system will stop at 7th record and all the previous 6 records will processed. In No screen mode all the 9 records will be updated except the 7th record(error record). and track the error u have to use BDCMSGCOLL in ur program(for call transaction).
Asyn-- System does not wait for Acknowledgement. but in Syn--- System waits for acknow. For this reson Asyn process is fast as compare to Sync.
Thnaks,

If I have two laptops connected to a single wireless hard drive, what happens when one laptop wants to go on a trip and the other one needs to stay home?

if I have two laptops connected to a single wireless hard drive (i.e. Time Capsule), what happens when one laptop wants to go on a trip and the other one needs to stay home? I'm afraid I know the answer, but I'm hoping Apple has a great solution to my problem.

What if this little piggy goes to market but this little piggy stays home?
The computer on a trip will do snapshot backups on the hard drive that will then be incorporated into the Time Machine backup once you get it back home. See
OS X Lion- About Time Machine's "local snapshots" on portable Macs
Open the Terminal in the Utilities folder and enter or paste the appropriate command line. Press RETURN and enter your admin password when prompted. It will not be echoed.
To turn them ON: sudo tmutil enablelocal
To turn them OFF: sudo tmutil disablelocal
Note that turning them OFF will also delete all existing snapshots.

What happens when i restore my iPhone?

i was curious as to what happens when you plug your iphone into itunes and click restore.
will i lose all my contacts and pictures?
and will it make the backlight on my iphone work?

A restore may help your iphone - it is one of the troubleshooting steps. Page 141 of the manual:
"If you restore, the latest version of iPhone software is reinstalled, default settings are
restored, and data stored on iPhone is deleted, including downloaded applications,
songs, videos, contacts, photos, calendar information, and any other data. In iTunes,
you can also restore from a backup without deleting data stored on iPhone.
Deleted data is no longer accessible via the iPhone user interface, but is not
permanently erased from your iPhone until it is overwritten by new data. For
information about permanently erasing all content and settings, see “Resetting
iPhone” on page 109. "
http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf
I gave you the link to the Apple article to determine hardware failure earlier. If those steps or a reset, restore don't work then you need to call or visit Apple for a replacement.

HT201250 What happened if a new backup has erased the previous one, can I still recover my files?

What happened if a new backup has erased the previous one, can I still recover my files?

Welcome to the Apple Support Communities
Time Machine doesn't erase old backups. That's only done when your Time Machine disk or Time Capsule gets full.
If you want to mean that you have connected the Time Capsule to another Mac to create another Time Machine backup, you should know that the old backup isn't modified, and you can still restore files from that old backup > http://pondini.org/TM/E3.html

What happens when i rest my iphone 3gs ?

iTunes will backup the device.
The device is erased completely.
The current version of iOS is downloaded.
iOS is then installed.
You then get an option to install the previous backup or as a New device.

I am due to upgrade my iPhone 3 to iPhone 5. I have icloud which co-ordinates my phone and mac what happens when I get a new phone - I dont want to lose all my contacts, notes, addresses etc. Do I have to disconnect icloud and how? What happens?

I am due to upgrade my iphone 3 to iphone 5. I have icloud which is co-ordinating my iphone 3 and Mac Pro updating each other. What happens when I get a new phone - I dont want to lose all my addresses, notes etc. What is the procedure and step by step action? The new phone arrives - then what?

When I upgraded from the iPhone 3GS to iPhone 5, I simply did a Backup of my phone using iTunes, plugged in the new iPhone 5 into my Mac, and did a Restore of that backup to put everything back. This procedure is documented around the web. Also, the new phone will ask you for your Apple ID and when you enter it, all your iCloud info will be downloaded to the phone. It worked pretty well for me.
