External backup

Oracle 11g on Linux.

The FRA is configured based ASM diskgroup + FRA.  Backups are scheduled to be put into memory at 02:00 every day.

Now, I want to back up the db and a second location (external hard drive, USB), in addition to the FRA.  So I will get two copies of backups, one on the FRA diskgroup and another on the external hard drive.

(1) how should I configure the RMAN to achieve this goal (of additional backup on the external drive)?

(2) backup the next day replace previous backup of the day? or just add additional new backup files on the disk (I use the default setting, which I believe is the full backup of database)?


Thank you

    I have a Version of El Capitan OSX 5 years 10.11.3, processor 2.5 GHz Intel Core i5computer.  It is slow and jerky.  Any suggestions?  I empty the trash. I have an external backup.

    Update your software OS X v10.11.4.

    If after the update is installed, you see always the same slow and jerky behavior, a Safe Mode boot removes the system caches that can help.

    Upper left corner of your screen, click on the Apple  > Shut Down.

    After your Mac stops, wait 10 seconds, then press the power button.

    As soon as you hear the startup tone, hold down the SHIFT key. You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

    Release the SHIFT key when you see the gray Apple logo and progress indicator.

    Once you are in Mode without failure, return to the menu Apple . In the drop-down list, click: reboot

  • What is a good external backup drive that won't empty my wallet

    I need to get an external backup drive for my PC, but do not know how to do in this regard. I've seen most are very Exspensive. Someone told me to get Seagate? Is - this right or which is a good thing?

    ... Someone told me to get Seagate?

    Seagate is trustworthy and has been for a long time. I also like WD (Western Digital).

    ... I've seen most are very Exspensive...

    The 'expensive' is subjective. The external drives that I've seen recently are <70 bucks="" per=""> terabyte. You can pay more for the bells and whistles of an external box which was dazzled, and you might get a player with a better fault tolerance.
    To say that males 70 from the perspective of my point of view, thirty years ago I paid $ 1,800 for a 160MB HARD internal disk.
  • How can I reset Windows Media Player to use songs on my external backup drive instead or in addition to the songs on my desktop with Windows Vista Edition basic hard drive family?

    How can I reset the Player Windows Media in Windows Vista Home Basic to use the songs on my external backup drive instead of (or in addition to) the songs on my desktop hard drive?  Currently, the Media Player library indicates that the hard drive (C:\) is my only option of disks to use for sources of songs.

    Basically, I want to have Media Player external drive for all the songs from research and build his library on this disc instead of on the C:\ drive.
    My problem is that the songs are hogging too much space on my hard drive, so I want to move to my external drive to backup instead, but Media Player will not access it.  I saw an option in Media Player to add a song to a different drive to the library whenever I play a song of this player, but that would require me to play all the songs moved one at a time, which is not practical, and which would not solve my problem because Media Player could still be maintaining the library on my HDD to say.
    Any ideas?
    Thank you.

  • File system for FRA and external backups

    Oracle 11g R2.

    The FRA drive is formatted using Linux x 83 put on Diskgroup + FRA system.

    Backups are stored outside on an ext3 file system.

    Suppose now the database gets completely crashed and I need to recover by continuing external backups.  I will copy the external backups to the + FRA disk and then perform the recovery from there.

    My question is, given that external backups are on ext3 file system, while the FRA is the Oracle ASM filesystem, there will be a problem for the use of the file systems of the two difference?

    Thank you

    Scott

    scottjhn wrote:

    To summarize the issue:

    In my system, the database will be on ASM disk group + DATA (disk1 disk2).

    I will use another disk, disk3 (ext3 file system) for FRA, to organize data files backups and multiplexed logs (archive logs, online newspapers and control files).

    Earlier you said "I'll use the + FRA (ASM disk group) for the fast recovery area that holds that archiving multiplexed logs, recovery online logs, and control files.»  Nothing else. »

    Now, I need one more place to hold the copy of the multiplexed logs.

    Wouldn't not on the same + (ABOVE)?  Alternatively, use a disk full-fledged, disk4 (ext3 file system)?

    Thank you

    Scott

    First of all, the reason for multiplexing online redo logs and control files is not the same as that of multiplexing archivelogs. Do it online and the control file are actually a part of the database.  The database will not work without them.  This is why it is so important to have multiplex.  Archivelogs, on the other hand, are part of your backup strategy.  The database itself really doesn't care if you have any archivelogs at all.  The archivelogs multiplexing is much less common.  I have never multiplexed mine, but I do not have a task that runs every hour to copy any newly created on a server off-site.

    If your database is on ASM, at least a control file and a member of each group of redo log must be in ASM.  Technically, is not having to be, but it's really foolish not to do so.  Where to put the second copy?  Probably several schools of thought on this.  If your FRA is on ext3, so it seems a simple decision... a FRA copy, a copy in its default location in ASM.

  • External backups Time Machine

    Hello!

    The MacMini to my dad, he has a backup storage more as external 4 TB Seagate and Time Machine recognizes it in the 'Options' from the settings page so that it can be part of the Time Machine backup.

    I don't have external storage but I do not use a Lexar 128 GB USB key to use to send files to and from school. However, in the 'Options' Menu, the stick is gray and I can't add it as part of the backup as the Seagate drive can. Someone at - it ideas? Is this something to do with the fact that the drive to Mac OS Extended format is 4 and my memory stick is FAT MS-DOS?

    Yes. Format the same as 4 TB drive. Disk utility and reformat the drive as Mac OS Extended journaled.

  • After the failure of hardrive how to reinstall from an external backup

    Hello

    I have a Compaq CQ61 424sa laptop and the hard drive failed while it is under warranty. I had done the recovery system, the system repair disc discs and have made regular backups and Image system so I thought it would be easy to replace the files, etc.

    I went to backup and restore (with connected external hard drive), choose "Select another backup to restore files", then choose the backup to restore. Checked the box "select all the files in the backup. Opinion said "all files will be restorations to their saved version on...» (date).  Click 'next' and all files seem to be transferred ok. Click "Finish" but nothing else happened. I re start, but nothing seemed to have changed. What I have to do somethng to another, or something different., and another question, does restore the programs and files.

    Thank you

    Hi erico

    Thank you for your time and effort, but I had to get a local engineer to fix it for me, he did leave the old files. It seemed complicated to me, but he said that the problem may have resides in the fact that I'm backup three pc on a single hard drive. I don't know if this makes sense but I seem to be ok again.

  • External backup drive is de-energized regularly

    Hello

    I use a network and wifi Time Capsule backup 4 separate computers. Some connect to the drive internal TC, some on a 4 TB external drive connected by USB to the TB. Once records have been chosen through the Time Machine preferences panel, everything works fine. I have exactly the same configuration for our office machines.

    Here's the problem: after some time, Time Machine stops to find the external drive. You can always climb through the Finder, but just TM will not be able to access them, as if she had been disassembled. Previous discussions with Apple revealed that the side of the power of the time Capsule may be a little light to drive an external drive at all times. As a result, I replaced the external drives by power units 3.5 inches. The result is much more stability, but I still have the question every two weeks, the problem reoccur. The only cure is to physically pull on the on the TC power cord and restart. After that, you are sure for a while...

    Measures of prevention/bugs/suggestions?

    PS: the TC is an older model (model square 1 TB), but works well. Same thing in the office.

    Tell me the exact model of your TC for 1 TB could be GEN 1, 2 or 3. The number of A1xxx down is what I need.

    Your problem may be also problems with Mac OS with DNS... what operating system running your Mac...?? They are all the same? Is the problem in all Macs exactly at the same time?

    IMHO, the TC is a lot a host device... and is not reliable enough for the office... leaving that aside... 2 weeks is actually not bad for routers these days apple... the last firmware was not as reliable as some previous ones... especially on old hardware.

    What you are experiencing is reported fairly widely... There is nothing that I can suggest to solve this... The question is drive interface USB is just not as reliable as the internal SATA interface.

    This drive USB/s are you running... I'm actually test Touro deskpro now to see how long he stays standing... So far the test has not been well, but I play a lot with network to answer questions. So I'll restart the test now... I would be happy if he stayed a few days to be honest.

    What I would say is

    1. with the help of a USB hub... I know that you use a hard drive powered... but we've seen the best reliability through a hub.

    2. If you have not get out of the car is not recognized... disconnect and reconnect using the player? Or have you restart the TC?

    3. try with 7.6.1 firmware instead of later.

    4. my last suggestion is to open the TC and the swap disk for a larger... 4 TB although you probably should also replace the power supply that is not profitable.

    5 buy a Synology NAS very superior to the joint installation of TC and USB use.

  • How to take the permissions of the user account for my external backup hard drive, incase of my computer crashed?

    Original title: backup of user account permissions?

    Hello

    I put permissions to my external hard drive so that it is accessible only by my account. For everyone, access is denied. I want to save permissions, in case my computer breaks down. How can I do this?

    I have only set permissions, not encrypted the files on the disk.

    Hello

    I will certainly help the question of fixing.

    Taking backup of permissions is not possible from your computer to an external hard drive. However, you can set a password for your external hard drive, so that you can access it from any computer that has administrative privileges by entering the password.

  • External backup error code 0x80070005

    I get a error code 0x80070005 when I try to do a full back up to my external hard drive.  He says "access denied" but I am the administrator. This problem just started.  I disconnected and reconnected the external drive and my computer recognizes that there is no problem.

    Hello

    1. don't he stops at any specific file?

    2. do you have permissions to the entire file for the files that you are backing up and to the destination you save back to the top?

    3. don't you make changes to the computer until the problem occurred?

    To work around the problem, you will need to follow the steps below.

    Step 1: I suggest to try to create a backup in the clean boot state and make sure that the antivirus software is disabled temporarily and check if that helps.

    Follow the instructions in step 1 in the following article. Run the backup and check if that helps.

    http://support.Microsoft.com/kb/929135

    Note: make sure you put the computer to a Normal startup, once the troubleshooting completed.

    Disable the anti-virus software

    Warning:
    Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  • Remove my external backup disk write protection.

    I can't save anything on my backup drive due to an error saying impossible because the disk is write protected. It happened when I updated to windows 7 November last month. Now I can't transfer all files on the disc. Help.
    I read an answer to my problem re regedit's local computer and system control etc. The problem is that I have storage in the registry but not in default extension just to hand right panel and without value. How do I manually write the correct version so I can remove my storage drive write protection.

    I did as you said in regedit as there was no policy of storage device, but it does not remove the write protection. My backup disk is a connected via external usb port. If I turn off the external hard drive and turn it on then I can move or copy folders on disk for a few minutes the write protection turns. It started only with windows 7. In vista, alol was ok re backups. I read on the manual for this player and they don't even mention protection against Scripture. How do I know which drive to remove the register write-protection? I think I solved my problem. I had my backup disk connected to the computer via a usb hub. I changed it to connect directly to the back of the computer and now the backup drive is not protected in writing and I can copy and send the disk to backup with no problems.
