Export is not for backup..... but...

Hi everyone!
Just curious to hear different opinions about the subject. I'm seeing a lot of posts that some are using export as a means of backup and as expected, there will always be a reply that export should not be used as a means of backup and that RMAN should be used.
so imagine a scenario where a database has like 5 schemas and that each of those schemas are actually used by 5 different applications. now one user accidentally truncated a table in his own schema and wanted to recover, that means backup has to be restored and recovered up to the point before the "accidental deletion". but a lot of things can be going on for the other schemas at that point too. plus what if the database is quite big which means restoring will actually cause longer downtime.
would it be more practical to just import the dump of that schema alone rather than affecting the other schemas?
again, just wanted to hear your thoughts...
*dont get me wrong, im using RMAN :-)

RMAN is powerful tool that was designed only for backing up and recovering the database

But if you truncate the table, you can perform point in time recovery not in the same server, but in the different server , get the table back and copy it to the production
Moreover, if you have Standby database and you haven't shipped the archived redo log file that contains "TRUNCATE" command, you can still get the table back buy opening the Standby database in read only mode and copy the table back to the production database
would it be more practical to just import the dump of that schema alone rather than affecting the other schemas? Imagine you have a database with some TB size and you take dailiy logical backup of all schemas ... Furthemore, you'll not get the latest data back, but take the table to the time when it was exported by missing some data

*dont get me wrong, im using RMAN :-)Keep using RMAN and use Data Pump to move data from one database to another :)
Good Luck!

I bought a new external hard drive for backups, but time machine won't do a full back up. I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?

I bought a new external hard drive for backups, but time machine won't do a full back up.
I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?
When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.

Triple-click anywhere in the line below to select it:
tmutil compare -E
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

Time Capsule does not show backups but

Timw Capule does not show backups but the Time Machine Preferences shows the dates of the oldest and latest backups. I shortened the name of the Time Capsule even though it was not over 27 letters. Sill can not see any backups when I enter Time Machine. It only shows NOW.
This occurred today, June 1st. I has a problem when I connected for the first time in May and it eliminated all prior backups for over 6 months and began with a total new backup. It does not seem to like new months.

This problem is typical of Time Machine on Mavericks.. have you upgraded a computer. When you started using Mavericks it will probably destroy all your old backups. But if you are trying to find a particular file, use the method in Pondini here to open the sparsebundle in Finder. You will not see anything via the TM in Mavericks.

You can and should read all the FAQ from 14-17 to understand other options for accessing old backups.

Can i have a seperate icoud account for backup , but use my families apple id ?

can i have a seperate icoud account for backup , but use my families apple id ?

if the backup is being done from a seperate device, it will show up in the icloud settings as a different backup.
lets say your sister has an iphone backed up to icloud and so do you. you just got a new ipad and you want to download all the stuff on you phone to it, no problem. it would come up as a seperate backup.

Can I use time machine for backup but also keep my itunes library on my external and not on my MacBook Pro?

I have two 1TB external drives that I planned on using for backup of my MacBook Pro (Not actually sure how to use them both as duplicate backups but I'l have to figure that out later). What I'm wanting to do is use the external as a backup but I'd also like to keep the majority of my music on the external drive so I can keep the space free on my MacBook. Is this possible?

Possible, but not advisable.
You would be using the same drive for backup & normal (live) uses at the same time. That pretty much negates the whole purpose of backup, at least as far as that single drive would be concerned.
Better to devote 1 drive to backup (TM or otherwise) and a 2nd drive for online (live) usage.
One more thing ... you don't really have effective backup until you have at least 2 separate backups on 2 separate drives, neither of which is connected to your Mac except for backup & restore operations. Three is even better.

I have an external hard drive that was formatted by a PC and has files and directories etc. I want to format it and use it on my IMAC for backup but I can't seem to write to it nor can I delete current content. How do I initialize it for use with the MAC?

I have an external hard drive that was formatted by a PC and has files and directories copied to it etc. I want to use it on my IMAC for backup. I see it on my my IMAC . I can open files etc. But I can't seem to write to it nor can I delete current content. I don't care if I lose current content. How do I initialize it for use with the MAC?

You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
http://www.macupdate.com/app/mac/24481/ntfs-3g
If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)

Ever since upgrading to Yosemite on my Mac, I can only configure my time capsule via iPhone. My Mac cannot locate for backup, but CAN find as my internet router. I have followed all suggestions I can locate and have upgraded to newest version.

Time Capsule in Yosemite can be used for router/internet but Mac cannot locate for backups.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Cannot see Time Capsule for backup but internet perfect A

I've seen other posts about time capsule problems and most talk about wireless dropout and loss of internet connectivity. My situation is almost the reverse:
Full airport strength in menu bar. Full access to internet sites on at least one computer. Cannot see Time Capsule via Airport Utility or in Finder on any computer. Time Machine backups fail (marked as Delayed in menu bar item).
If I reboot (via unplugging) the Time Capsule, it shows up again in Airport Utility and backups are successful. This has happened three times now. I think the first time was prior to upgrading the firmware. The second two times were after the Time Capsule firmware upgrade. In the second two instances, it looks like the backups run for about 12-13 hours, every hour. No problems. Then, they drop out. Yesterday, it ran from 8:30 AM until 9 PM.
I've got two Macs (a Powerbook G4 and a MacBook Pro), each running latest software updates (security, 10.5.2, etc.).
Unplugging (rebooting) my Time Capsule each day is not an option. That's partly why I moved from an ancient LinkSys router that always needed to be rebooted since we lost local and internet access. Any help is much appreciated!
Cheers,
Drew

Have you set up the TC with user accounts??
Most people just use the TC password..
I have done very little with user accounts on the TC.. it seems fundamentally wrong headed to me.. If you have a domain controller with everyone using accounts to login that is fine.. and the TC would then exist in connection to the domain controller.. but it is a home device and there is no function to all that.
What will happen if you change over to standard security or even turn on the guest account I am too scared to suggest as you may not easily get connection back again.. The TC certainly displays a warning going to accounts.. I am not sure of warnings going away from accounts.
If you didn't setup the TC, do you have admin access to it??
Perhaps I am assuming too much before you tell me everything. But I may suggest things you don't want to try.. unfortunately I cannot say this will work.. the issue is widespread across the Mountain Lion TC combo and I have yet to see Apple suggest a solution or even fess up there is a problem. Daily reboots are just simply now a part of the scene for all windows and Mac users.
Is the TC the main router for the network.. 1 hour is not default lease in the TC and very few people even know how to change it.. standard is 1day. I would consider 1hr adequately short for all arp tables to be kept up to date.. the computer should be seeking new lease at 30min.. ie half lease time.
If the TC is bridged an not controlling the network.. that can contribute to the issue.
Setting a static IP on the TC if it is bridged my help.

How to Export 320x240 .mov for Web, but darker and more saturated?

Hi, I am trying to improve my Web .mov movies.
My goal in this thread is to learn a good way to simply set a darker black and bump the saturation.
I don't understand what I am doing wrong because the movies on apple.com always have a good black point and great saturation and my workflow of exporting leaves my movies looking light and washed out from my original.
I recall I have also tried Compressor with similar results.
My monitors are hardware profiled to 2.2/6500.
From FCP 6.05:
File> Export> Using Quicktime Conversion
Settings:
H.264
Frame rate: 10
Key Frames Every 24 frames
Frame Reordering checked
Quality: High
Best Quality MultiPass
Restrict to 500 kbits/sec
Filters:
ColorSync (I am experimenting setting Source and Destination profiles to sRGB because my Sony SD footage and .tif files are not associated with my custom monitor profiles) — otherwise I have not messed around with any filters.
Size:
320x240 QVGA
Sound:
I am only switching to Mono
If anyone has any tips using FCP I would love to hear them...

Real friggin crazy...

Re: h.264 gamma and/or color off
Posted: Mar 14, 2008 4:11 PM in response to: Dave Mauriello
I have been spending the better part of 2 days trying to figure this out. So far I have learned that Quicktime is displaying a gamma shift in the rendered video and that the actual file is okay, it is quicktime that is messing it up. This also goes for anything that uses quicktime, like safari, itunes, and similar players that use the Core Video hardware acceleration. Computers or Players that don't use hardware acceleration will show the same file correctly when played. But of course this is still an issue for anyone viewing your video on another computer with hardware acceleration enabled. To them your video will look faded.
It happens far worse on windows machines where the gamma is set to 2.2 (my mac was set to 2.2 until I found this nasty H.264 bug in quicktime rendering.) In the 2.2 gamma environment the shift in brightness is very pronounced. In the 1.8 mac gamma environment, it is less pronounced but still problematic enough that many of the studios that I know won't use Quicktime or the H.264 codec until this bug is corrected.
This problem is documented all over the web and it has caused major headaches for a lot of people for somewhere around 3 years. So far Apple hasn't done anything to fix it (or can't fix it) even though it is a persistent problem, especially for people who calibrate their monitors or people on PC's.
It's really frustrating and after hours of scouring the net for an acceptable solution, I still haven't found anything that doesn't involve simply not using quicktime or h.264. Here is one (partial) solution I found:
This tip from Mitch Gates:
As you may have noticed, the current implementation of the H.264 compressor for Quicktime has the nasty side-effect of raising the gamma or black levels of the resulting movie file. In order to fix this you must have Quicktime Pro (otherwise the fix will not hold since you can't save the updated .mov). Here are the steps?
Open the QT
Go to "Window/Show Movie Properties"
Select "Video Track", then click the "Visual Settings" tab
At the bottom left, change the transparency to "Blend" then move the slider to 100
Change the transparency to "Straight Alpha"
Close the Movie Properties window, then play or scrub the QT. Your black levels should now look correct
Save over old .mov
This is for PC's. On the mac you change the transparency to "composition."
The problem with this solution however is that doing this disables the settings that allow fast playback (playing the movie before it is completely downloaded.) Another issue with this solution is that, while it fixes the look of the video in Quicktime, VLC player still exhibits the 'washed out' look on the same file. Finally, this "solution" isn't actually a solution at all.
An interesting thing about this is that the video file itself is not really washed out as far as I can tell. There are a few things that point to this. One, exporting the h.264 file and changing the codec to "Animation" or "None" corrects the gamma shift and returns the colors to where they should be, but this increases file size dramatically. Second, I noticed that when I select the h.264 file and choose "get info" the preview thumbnail shows the poster frame with correct colors. Third, when I put the h.264 file online Safari shows it all washed out but FireFox shows it correctly. Strange...
At this point I think the only viable solution is to do this:
MacInTouch Reader
I too have been plagued by this H264 problem for the past 2 years it seems.
I have a suspicion that if we polled the users experiencing this effect that it would result they all use custom or modified Display Profiles in the Display System Preferences.
My temporary (and somewhat silly workaround) has been to change my display profile to the standard "Cinema HD Display" instead of my user-created "Cinema HD Display Calibrated" profile.
It does alter the gamma of my display to a unpleasing value, but after changing it, the H264 export works beautifully. No gamma shift at all.
I have read all the suggestions on trying the quicktime "filter then colorsync" export and always got unsatisfactory results. My silly workaround always produces the best results. I just have to change the dang setting back after I export so my eye don't burn out of my skull.
So it all comes down to a gamma shift on the part of Quicktime's render of H.264. You would think that after so many years of this issue going on Apple would have fixed it since they have documented that they know of the problem. A little baffling.
If you want to research this further, as I will continue to, just type "h.264 gamma" into google and you will find a ton of fellow frustrated users trying to figure this out. Most just switch to Sorenson 3 it seems or "un-calibrate" their displays when doing the render export. None of this is perfect unfortunately and I find myself using "Animation" even though the file size is insanely huge. It is better that having upset clients telling me that the video is washed out.

Cannot access Time Capsule for backup, but wi-fi is fine

Hi all,
from time to time, suddenly any Mac in my house is not able to connect to TimeCapsule, while wi-fi is working fine. I can access Airport utility and see and configure the hardware.
The only working solution is to switch off Time Capsule by unplugging power cable, then plug again.
Time Capsule wil allow again to reconnect and back up via time machine.
The log seems to show this message:

On Location is not for sale, but I need more copies of it at shoots than the 2 allowed by the EULA.

I have 3-8 cameras at my shoots. I use On Location for capture. After purchasing CS5, I discovered that the CS5 EULA allows '2 installations' max and there are no extended licenses available for On Location.
Now, OnLocation is not available for purchase seperately from Master Collection CS5 or Premiere CS5, so I cannot just buy a few more copies of it. So how the heck can I put On Location on 5-8 seperate capturing laptops, without buying CS5 4 different times?
Installation of On Location alone on additional machines results in a 'activation limit exceeded' screen when I logon to the capture laptops (post installation). I guess I could deactivate the Network Card to avoid the software communicating with Adobe, but I use it to transfer footage to my Network Drive at the end of each day
Any insight?

Is there an app for that?

Flash is not supported on the iPad - and as Adobe have announced that they are stopping development on all mobile versions of it, it probably never will be.
Do the sites that you want to use have their own apps in the store ? If not then there are browser apps such as Skyfire, iSwifter, Puffin and Photon 'work' on some sites, but judging by their reviews not all sites.
