Backup copying data files
I've heard some people perform backups of their databases by just saving to tape the database files (.ORA files). Of course the previous step is to stop database service.
I usually export my schemas and then backup the .DMP files. Sometimes export of large databases can take long so my question is, what are you missing saving the database files (I mean not exporting schemas) ???
Neither method is a "real" backup from the standpoint that it is more likely to fail and more likely to be incomplete than doing it the right way:RMAN
Read the RMAN docs at http://tahiti.oracle.com
I think these days most employers, I know it is true for myself, will not hire anyone that does not consider RMAN the only way to create a backup.

OraRRP Error with "Unable to copy data file;Error code 2, check disk space"
Hi,
Some users get this message -"Unable to copy data file;Error code 2, check disk space" when run report with orarrp, but most users do not get it.
I check free space at both server and client side, they are very sufficient.
I also checked directory exists for REPORTXX_TMP variable.
My user call reports via URL (rwservlet) and it occur for all reports.
How I can solve this problem?
Thanks in advance.
Tawatchai R.Hi,
have the same problem now. One user has temporarily problems to download .rrpa files via URL (rwservlet) request. Error code: -"Unable to copy data file;Error code 2, check disk space". Did you get a solution??
Thanks in advance. Axel -

Edited by: zycoz100 on Feb 27, 2013 4:42 AMA controlfile create is a fairly trivial task, for either a cold backup or hot backup scenario. Well, its an easy task after you've done the process a few times.
If you have a healthy oracle instance running any place else, preferably at 11gR2, or even a 10g instance can work as an example, get a system connection and do an `alter database backup controlfile to trace;` and the instance will create a new trace file with all SQL commands needed to rebuild the controlfile in the instance trace directory.
Have a look at the trace file, a `show parameter diag` reveals the diagnostic_dest parameter, look for the "trace" directory under that folder, for the latest *trc file. In 10g its `show parameter dump` and the trace file goes straight to the user_dump_dest directory, no digging required. -
Time Capsule by default backup only data files and excludes program files like Photoshop, Lightroom, and MS Office, etc... right since if crash I can reinstall and not want to take up disk space for applications that I have CD to reinstall? Or do I have to manually exclude these?
Time Machine will back all files except files like caches, trash or temp files, you can select with file you would like to exclude by going into the Time Machine preferences.http://support.apple.com/kb/HT1427

Copying data files to separate partition
I am using Oracle 9i Release 2 with Windows XP and I would like to store the tablespace or data files on a separate raw partition. I was told that this could increase performance. How would I go about doing this?
Thank you,
MalinaFirst, to the best of my knowledge, Windows doesn't support raw partitions. I've only ever heard of using raw partitions on Unix.
Second, this is one of those things that if you have to ask the question, it's probably not appropriate. Raw disk partitions are significantly harder to manage than normal partitions, so if you don't have the storage administration background to deal with this added complexity, it's really not worth it.
Third, the performance difference between raw disk and normal partitions is pretty small and affects only certain operations. The difference for most systems will be small-- unless you have run out of other things to tune and really need a couple of % boost, I wouldn't even consider this.

Copying data files from Mac to Windows on MacBook running Parallel
How can I copy .doc files from Mac folders to Windows folders?
I am running Parallel but I cannot access the Mac folders and files when I am running Windows.
I cannot access flash drives from Windows either.
Can anyone help?
Thank you
MacBook Black Mac OS X (10.4.9)Theres a feature called shared folders that works
quite nicely. I cant quite remember the specifics but
I have done it before. Or if you've got a few small
ones copy and pasting between work spaces now works.
Cheers, Arthur
Now all I need do is figure out how to turn on the sound when using Windows. Everything is as it should be on my Xp setup but no sound. Mac must be controlling this but I do not know where to look to solve this situation.
Have a great week,

Can I copy .dat files in Quicktime?
Hi..I received 2 .dat files which play in Quicktime. They are pieces of 2 movies which were converted from Video and given to me on a cd disc with a wesite.
I want to edit the movies and also lighten them up, because they is very dark.
I am wondering if I would need to do it in Quicktime, since it is the only thing it appears to play in. Or can i do it in iMovie or Final Cut Pro? And how would I get them in there, make a duplicate (in order to save these originals) and then do editing and use them both for the website, as a mpeg4 or 3 and also as files for output to cd's? Can I get them out of the .dat file format?
Obviously, I know nothing about this. Thank you.
Powerbook G4 Mac OS X (10.4.6) 1.25 gig ramStreamclip is an application that is used to convert mpegs to other formats. It is not a format itself. Since the video has no sound you may not need Streamclip. Change the extension from .dat to .mpg and see if your other applications will then recognize it.
Some versions of iMovie will accept mpegs for input although they do convert the mpeg to DV Stream and open as an iMovie. If your version of iMovie doesn't do that then use QT Pro to convert it to DV Stream and then you should be able to edit it in iMovie and "Share" as some other format. DV Stream is not practical as a format for web posting, as it uses too much filespace -- almost 7 megabytes per second.
You mention losing quality as a concern. That is always going to happen if you convert from one compressed format to another. However, I am not aware of any other way to change the brightness that would affect how it would look when viewed on another computer. -
Hi,
am using following rman block to take incremental backup copy for recover.
run{
allocate channel c1 type disk format 'd:\copy\%f';
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG 'full_backup' DATABASE ;
It creates backup under D:|COPY directory but the name of backup copy is file# of datafile. How can I take backup copy which has same name as actual data file i.e. users01.dbf?
Thanks
SAQWith an FRA defined (via DB_RECOVERY_FILE_DEST_SIZE and DB_RECOVERY_FILE_DEST), the command is simply
backup incremental level 1 for recover of copy tag 'MY_TAG' database
A FORMAT specifier is not required.

What happens if you Time-Machine backup an encrypted file-vault HD?
This is related to my previous post - but deserves special mention for those people who are using time-vault AND Time-Machine.
My question is this: If the backup of my Hard-drive is encrypted, and I then reinstall from backup, what will this situation likely produce?
This is what I have done. I also Archived and installed my Mac prior to installing from my Time-Machine backup.
I now have an error message that displays the following message at the login screen:
"Unable to log into the file-vault account "......." at this time. An error has occurred."
My password IS CORRECT. I have not changed it, and the log in window does accept my password, but it doesn't progress any further than the error message I gave above.
I'm wondering if the encryption process of file-vault is linked directly with the original installation I had of Mac OS-X before I Archived and installed.
Any thoughts/knowledge/Insight?? I want my old Mac back! (I don't recommend using file-vault). Any body else had this problem or can see what is happening to me here?
Thank you
GregI just did a backup, moved a folder with 600mb of images into a different folder, and did another backup. The free space on the backup drive dropped by the size of the folder's contents. The backup copied the files as I watched in System Preferences, and it looked like it was really copying the files to the external drive again. It looks like Time Machine isn't as smart as I hoped in this regard.
Still - I'd think the wasted space is only in the every-hour-for-the-last-24-hours bucket of Time Machine. I'm guessing the every hour backups are like a sliding window, where a backup that's 24 hours old drops out every hour rather than all the hourly backups getting wiped at midnight and starting over.
Regardless, only one version of the moved folder will eventually be stored as the daily backup for that day. I don't have proof, but that's what I think.
So, if you've moved a bunch of folders around or renamed them, the extra copies of the same exact files should drop off within 24 hours.
That's my interpretation, but I'm in no way positive!! The lengthy Ars review didn't offer an answer to this question. -
Using DVD-R as backup for data
I thought I could use a blank DVD-R disc as backup for data/files, as I've done with blank CD's in the past. However, loading a blank DVD just starts iDVD and I can't figure out how to transfer files, plus there is no disk icon on my desktop. I'm sure this is a real beginner question, but I just got my iMac. Thanks, David
Hi David
First thing you need to do is change your preferences so that the DVD mounts on the desktop. Open System Preferences by click the Apple menu in the top left corner of your screen and selecting "System Preferences..."
The select the CDs & DVDs pane in System Preferences. You can change the "When you insert a blank DVD" option to "Ask what to do". You can now close System Preferences
The computer will then ask what you would like to do when you insert the blank DVD, selecting "Open Finder" will mount the DVD on the desktop.
Hope this helps

How can i copy my data files from a windows backup to mac mini
I recently purchased a mac mini and waiting on its arrival. I am converting from WinXP and my current system is not working at the moment (started smelling smoke one day and the video hasn't displayed since from the PC - so its been shut down). I can easily fix whatever the issue is with the PC - however - my question is. I perform periodic backup of my data files to an external drive with Windows Backup, can I restore my files from the Windows Backup to the Mac Mini? If I don't have to fix the PC - I can save that cost and buy an CD drive for the Mini (or something else).
I haven't investigated the real problem on the PC - I just know its hardware related (not OS).
My last backup was atleast 1 month ago - so I know I might lose a couple of things....but not very much. If its "simplier" for the migration process to fix the PC - then that is the answer but if I can extract from the external 1TB Seagate. I think I only have 50GB of data (itunes / pictures / etc)

2006 iMac running 10.4 OS. I copied files to ext. drive. Put in 10.6 disc and did a clean install (format) of 10.6. Copied data from ext. drive back to Mac. I didn't get all the files. CAN I REVERT BACK TO THE 10.4 OS SO I CAN COPY MY DATA PROPERLY?
How did you copy files to the external drive, and what files did you copy? Did you drag and drop in the Finder? Use a clone utility? What files did not successfully copy?
If you reformatted the drive as part of your install, then you won't be able to recover any files from the drive. Reverting back to (reinstalling) 10.4 will not help you.
Do you have a complete-drive backup of your old system?

File copy/paste adds " - Copy" - how to change to " - Copy" + date/time?
Is there any way I can change the default file copied name from having " - Copy" at the end to " - Copy" plus the date and time?
Before editing files I always make a copy of the existing file so I have a backup. I do this by clicking on the file I want to change in the list of files then do Ctrl C and Ctrl V which creates a copy of the file at the end of the list of times, with "- Copy" at the end of the name in the format "index - Copy.php". Is there any way I can get Dreamweaver to add the date and time to the name which would save me from editing the name and adding the date and time every time. Its a pain having to do this but I don't know any other way to ensure I know the date and time the file was copied. I know that there is a Modified date and time but changing a template for instance changes that and besides the file could also be edited but having the name reflect the copy date/time allows me to have the Modified date/time as a double check. I would like to have the file name in the format "index - Copy20110216 1621.php", the date being the international format and the time slotted on the end of it. This then puts the files in date/time order in the list.There's no way of customising a copied file name using DW that I'm aware of.
Either rename it manually in DW or use a 3rd party file copy utlity outside DW.
Is there a reason for keeping a hard copy of the last copied date that the Last Modified date in the operating system does not record?
