Difference between backup and timemachine?

Why is it that Bckup can determine which indvidual files have changed in Aperture and timemachine cannot?
I think its totally stupid that if I add one 2 meg photo to time machine, 60 gigs. Yes thats right 60 gigs has to be written to my time machine harddrive.
Why can the ancient apple backup utility work this stuff out and the uber cool 22nd century time machine cannot.
Yes I am frustrated. The most important files to me are my photos. And yet its these files that I have to exclude if I don't want to bog down my network for hours at a time and use up a 500 gig harddrive in just over 3 weeks (based on one week of time machine backups with aperture included)

Well, I can't really help you. You have all the relevant information.
FileVault presents new problems for TM because TM will not backup a FV protected account until after the user logs out. If your backup is on a network device then TM has to back up the sparseimage file each time it backs up (at least that appears to be what happens.)
Backing up to networked drives makes the whole backup process much slower, but I don't know if you have alternative solutions available to you.
Personally, I don't and won't use TM. I much prefer a third-party utility with much greater flexibility. My suggestions:
Backup Software Recommendations
My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Intego Personal Backup (Commercial)
9. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility.

Difference between backup and sync ?

What is the difference between a backup and doing a sync ?

backup is part of the sync procedure. If you uncheck the "Sync contacts to.." box under the phone info, special field names used in the contacts list won't get lost as they will if iTunes tries to stuff your contact fields into some address book on your host computer. Create a contact with a few phone numbers like "Main" and "Support" and "Shipping" as additional phone numbers. Do a SYNC, and check your address book on the host computer. You'll find that data is simply gone for these additional phone number fields.
Apparently if you don't SYNC to an address book, the sync/backup procedure saves the special fields in the backup directory. Maybe it even saves these fields if you backup using the SYNC approach, but this isn't the impression left by 2nd level tech support. Their solution is to get mobile me to keep your contacts list from getting corrupted or losing data.

Is there a difference between backup and sync?

I'm really confused....
Looking at iTunes (on my pc), I see all my apps there, with the amt of space they take up. However, when I look at my latest backup on my iPad, it lists the very same apps (I think!!) but shows "no data" on many of the apps that show up when I look at them on iTunes. What is going on here? I'm trying to back up my iPad to the iCloud and it doesn't back up all my apps. I have 4.7G of space available on my cloud. I've tried several times over the past couple of days. I've done a "soft reboot" on the ipad, turned it on and off, backed it up to my computer, etc and still, when I try to back up to the cloud, only some of my apps are showing. Is it something stupid like I don't have them checked somewhere? Because I've looked in iTunes (on my pc) and on my iPad and all the apps are checked. Thanks for your help. This is driving me nuts. :-/

Yes, I have all my apps to sync with iCloud. And according to the backup file size calculator, it's only 300M or so, which is WRONG. I f I add up all the apps (set to "on") it should be well over 300M. It will not, however, exceed the 5G of free cloud space.
I also have an iPhone and use the cloud with it, too, but it has a different AppleID for iCloud. Both my iPad and iPhone use the same appleID for iTunes. I set it up this way to get 5G of could storage for each of my devices. And it looks like it worked (5G available in each iCloud account) except the iPad backup isn't complete, and as I have stated earlier, is nowhere near the 5G limit.

Whats the difference between list and lov ?

Whats the difference between list and lov ?
i can do the same things with a list what an lov can do .
infact a list is more better. cause the list doesnt hold/show a range of values, and only has the items value iteself.
while the lov can get all the values of items depending on the query.
like
select ename, job, sal from emp
will show all the three items values in lov?

Also, if you're looking in the US store, the prices are:
- Airport Express (small, no ac) $99 - Has audio out for speaker connection using Airplay. Can share a USB printer only.
- Airport Extreme (larger, ac) $199 - No audio out, can share a USB printer or hard drive.
- Time Capsules (2TB, 3TB at $299, $399) - have ac wireless and a backup hard drive for Time Machine which the other Airports do not have.

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

The NEW macbook Pro and Air are EXTREMELY close in form factor
The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
both Air and new Pro now have PCIe SSD and permanent RAM.
The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
both have 802ac wifi
both have permanent RAM, no superdrive
both are slim profiles and SSD
The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
....and of course the retina display
both are now "very good for travel"
Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
You need an external HD regardless of what you get for backups etc. Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
Maybe a “macbook Air PRO with Retina display”
Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little, the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
there is no magical number of pixels per inch that automatically equates to Retina quality.
http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution- of-those-new-retina-display-macs-feature/
A huge internal SSD isnt a game changer for anything, you need an external HD anyway
what you WONT READ on Apple.com etc. is that the larger SSD are MUCH FASTER due to SSD density
"The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD"

What's the difference between photos and albums

I'm trying to figure out what the difference between photos and albums is on my ipad 'photos' programme.
What I'm really trying to do is to delete photos from my phone so that I'm not going over 5GB on my icloud and I don't want to lose them, so I'm checking to see where they are stored on ipad.

Hello julian
As far as what iCloud backs up, it is backing up the photos and videos in the Camera Roll. If you want to ensure that your pictures are backed up, then follow the steps in the last article to import them to your computer. One thing to note is that you cannot import your albums that you create. If those photos are not in your camera roll, import the photos to your camera roll.

Difference between exipre and obosolete

Hi ALL,

Hi ALL,

But the expired means that couldn't be found after CROSSCHECK command executed. See the following example. In this example the retention policy is set to redundancy 1 which means that the backup which have more than one copy, is marked as an obsolete. Then I delete a backup, run CROSSCHECK command and see that the deleted backup marked as EXPIRED

What's the difference between tags and albums

I've always used tags, I don't really understand why you would use albums instead of tags.
Say I've got pictures of birds, I would apply the Bird tag.
Where exactly do albums come in?

Another thing to keep in mind with the differences between albums and tags.
Both albums and tags are stored in the catalogs.
Tags can be also stored in the picture files themselves; they can be accessed form your OS or other applications. They are still available if the catalog is missing or corrupt. The organizer does only 'write metadata' to files if you specifically issue this command. On the other hand, albums can't be saved in the files themselves. They are kinds of 'playlists' which can only be stored in catalogs. That's why it is important to backup regularly. The standard backup process saves the catalogs as well as the image files; if you use an external backup system, include the catalog folder (found with Menu Help/System information) as well in your backup procedure.

What is the difference between express and extreme?

I am wondering what is the difference between express and extreme and will there be any effect in performance if I am just using it at home?

I am just looking for router that gives me reliable highspeed wi-fi for personal use within my home.
Wireless performance is roughly equal between the two devices, with a slight edge to the Extreme since it uses a bit better antenna package.
If I connect the the hard drive to the extreme, does that mean I can back up all my data wirelessly through the port into my external hard drive?
Yes, if you backup manually, or use an application like Carbon Copy Cloner or SuperDuper.
No, if you were planning to use Apple's Time Machine application since Time Machine backups to a hard drive at the USB port of the AirPort Extreme are not officially supported by Apple.

What is the difference between null and NULL?

There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload

              filename                = filename

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2
