• backup compression

  I saw SecondaryConfig.setAllowPopulate and imagine that it could be used for the backup compression.
  
  If I only back up the primary dbs and rebuild the secondary dbs during execution of recovery, I put a lot of drive backup and bandwidth time/strip space.
  
  Above and how can the true I achieve that?

  Hello

  Which allows to SecondaryConfig.setAllowPopulate () is a secondary database be filled if it is empty. This is useful when you create a secondary database at a later date than the primary database and need the secondary image to be up-to-date with the primary and contain all secondary keys it would have contained if created at the same time with the primary.

  There is no relationship between this method and the backups. Backups EI are subsequently copying all the log files (the file *.jdb in the Directory environment I or subdirectories) to the backup location. Performing backups EI is explained here:
  http://docs.Oracle.com/CD/E17277_02/HTML/GettingStartedGuide/backup.html
  http://docs.Oracle.com/CD/E17277_02/HTML/TransactionGettingStarted/backup.html
  Recovery involves the opening environment I normal title that will automatically run the normal recovery of I. This is explained here:
  http://docs.Oracle.com/CD/E17277_02/HTML/GettingStartedGuide/catastrophicrecovery.html
  http://docs.Oracle.com/CD/E17277_02/HTML/TransactionGettingStarted/jecatastrophicrecovery.html

  When you save, you save the files of newspapers I which contain all of the databases. You can't choose to selectively only certain log files or some parts of log files that contain nodes reflecting data from the primary database. In addition, you can't control the recovery process when opening an environment to make it only to recover some databases.

  You must use a different approach outside the process of backup/restore regular EI. You can use DbDump and DbLoad either separately as utilities or programmatically from code to empty only primary databases to the location of the backup (the backup environment), then load them there. When you perform a restore, you open the environment backup (which runs the normal recovery) and the secondary databases for automatic filling of opening / creation.

  Or maybe a lot easier, keep the usual backup process for an environment of I (by a backup off hot or connection, where a full backup) and after copying all the log files of *.jdb of the direct environment on the backup environment, open the backup environment, use Environment.truncateDatabase () to empty the database side, followed by a call to Environment.checkpoint () and Environment.cleanLog) only the backup nearby environment. This way, you will have a backup environment that bears the names of secondary database with these secondary databases are empty. They can be created during recovery, after the opening of the environment, when you open the secondary database configured with SecondaryConfig.setAllowPopulate (true).
  Note that this approach is not feasible if you implement incremental backups, because the new log files that you copy in the backup environment will contain entries referring to the secondaries.

• ESX 3.5 backup Suggestions / Help

  Hi all!  It's been a while since I've visited these forums but recently I tried to get a plan to back up our virtual environment.  First, here's a quick description of our virtual environment:

  3 Dell PowerEdge 2950 with 32 GB of RAM each, NIC 6 (2 on board, 2 dual port cards), each two-processor Xeon 5345

  1 Dell / Equallogic PS400E SAN

  ESX 3.5 UPD 1 Standard x 3, VC 2.5 Foundation (non-virtual)

  Here are our current backup environment / method:

  CA Arcserv 12 backup each VM (local disk + the system state) as a backup of 'level of files', something in the neighborhood of 2 TB - not a backup complete VM

  I've suggested that we do was buy VMware Agent for Arcserv of CA software and a basic backup unit (unit 3 TB ExaGrid) disk which should be installed and configured by our SAN provider.  The idea was to start to full backup of virtual machine alongside our backup process normal precautionary measure for the updates of the firmware of the SAN, semi DR, software ESX upgrades / updates, etc.  Essentially to give me peace of mind and a way out of what I consider to be a 'disaster' that is losing the San or a firmware update gone bad.  Due to the cost of the solution, the idea was struck down.  Now, I'm first trying to find an "cheaper" alternative for giving me some peace of mind.

  Some of the ideas I had would be to buy a NAS cheap with sufficient capacity to allow me to get a complete virtual machine backup before making any changes I need to do but I'm not sure what all I would need to be able to do something like that.  Would I need to the Arcserv for VMware agent or something like that (maybe EsXpress or vRanger Pro etc connection) or I could shoot with just VCB?  Would it be possible to not even use VCB and up volume on the SAN, and copy the files or do I need something like VCB to put the files in the correct state?  Any thoughts would be appreciated, thanks!

  When VCB puts these offline files is the virtual machine offline, the duration of the backup?

  N ° snapshot functionality has been designed so that you don't have to take the virtual machine offline.

  With Arcserv (or VCB) to put the files somewhere I think it would be unwise to put them back on the SAN then maybe local storage (DAS) or storage (NAS) networking maybe?

  Thaat's what we do as well.  We are valuable SAN performance real estate for the archives, which would be a waste, so we use the SATA storage premises.

  Or are you saying that acrserv should be able to recover the files from the SAN to bring broadband (or other)?

  Probably better to stage, the first save, perhaps of local disk, a NAS or Windows file store.  Use your backup software to process these files as you would for a physical server, and then move those band.  You can probably go live on tape, but if the backup fails, you are wasting time / Ribbon, featuring it it will be easier to manage also.

• Is it possible to recover a database with the copy of data files (cp), while the database has been opened?

  Hello

  We know we need to do a backup of an oracle database by using the appropriate tool, in most cases the rman. But we have in our society, a person who helps us with the backup of all the databases oracle we have. Thus, in addition to the rman backups, we do a copy (cp) with the open database of all files in oracle database, (without start backup) including of course spfile, controlfile, etc.. My question is: can recover us my database using this copied data files? or are we just wasting disk space on our backup environment?

  Kind regards
  Melo.

  We're doing a copy (cp) with the open database of all files in oracle database, (without start backup) including of course spfile, controlfile, etc..

  As EdStevens said, it's essentially a backup without value. When you copy files from a backup ' hot', there may be inconsistencies in the blocks of the file as transactions actively edit these blocks while the copy is made. Mechanism of Oracle backups hot managed by users is to put the database or tablespace in backup mode, copy the files, and then the end backup mode. Without this mechanism, the chances of being able to restore from this backup are very, very thin.

  My question is: can recover us my database using this copied data files?

  My question is... have you tested recovery? If the recovery has been piloted, then called the answer to this question. Please read the end of this blog post for more information:

• Slow on vSphere and Arcserve r15 VDDK

  Hey guys,.

  I'm recently affected by a performance problem with Arcserve R 15.0 on vSphere 4.1 using VDDK. Without modifying our backup environment documented some computer virtual guests have slowed up to 300 MB/min on the safeguarding of our FC SAN.

  Ive assured that they are without previous snapshots and other guests of VMs on the same backup of the data store, as expected. I also checked other guests of virtual machine on the same hosts as the invited backup troubled, as expected and I looked inside the bone from the guest to the fragmentation on disks and everything seems normal.

  I have all the necessary logging enabled in Arcserve and see nothing of really exceptionally. I checked the file VMDatastoreTypes.ini has the SAN setting of 0 for the vm problem.

  Can someone shed light on this question or direct me in the right direction?

  Thank you

  Hi all

  This is Arun. I work with CA Technologies on the CA ARCserve productline.

  The response to a related question that we have VMware, advanced transport mode is used whenever a temporary directory is created for the particular VM mount disk for hotadd and mode of SAN. If for any reason any backup were to fail, this directory does not get deleted and the mode of transport advanced next time is used for the same VM it fails with the error message "not available for the opening... advanced transport systems. ". According to VMware, the backup fails because it is impossible to create a temporary directory, because the directory already exists. The user may need to remove the temporary directory and then try again.

  The TEMP directory created during installation VDDK is "C:\Documents and Settings\Temp\vmware-Director. This path is used to create the directory for the modes of transport advanced automatically, if the user does not specify one in the VixDiskLib_InitEx or the VixMntapi_Init.

  Instead of delete the temporary directory, I would recommend to just simply rename the directory and try again. I would like to know if it works. We are very determined to get your backups on the rails and you can also send us an email if you need help. Please use our email from twitter, we still have not a specific forum, [email protected]

• Backup/restore of errors Windows 8 feature is not available in a portable workstation environment

  I get the following error message when you try to disable the calendar jobs '

  Backup/restore of errors Windows 8 feature is not available in a portable workstation environment

  I'm on a desktop computer,

  Thank you James. This procedure has helped and I can see the option to backup again to 8/7 of window control center. What I did wrong in the first place was canceled the backup on an external disk, formatted the disc one plugged a new drive. Then, I was not able to click on the link "Backup." Its now fixed. Is some other problem with the problem of recognition of backup or drive window, try this procedure by Michael below.

  Follow these steps to remove the value of register Windows To Go:

  • Open regedit.exe
  • Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
  • Delete this value: PortableOperatingSystem

  You'll probably notice that the problem reappears when you connect a USB drive in the PC. Subsequent removal of this drive will cause the PC to crash. This occurs because the unique identifiers of the USB drive and the internal HARD disk are the same. To resolve this problem, the simplest method is to "clean" the disc. A cleaning will destroy all data on the disk, so backup first.

  1. Open diskpart.exe
  2. Type "list disk" to determine the number of disk to the USB drive.
  3. Type "select disk #", where # is the number of disk you determined.
  4. Type "own."
  5. Type "exit".

  Restart your PC. You can use diskmgmt.msc and diskpart.exe to repartition your drive USB to use it normally.

• My backup on a NAS system in a separate Ethernet environment takes about 30 hours for 222GB

  Hello

  someone has an idea how spee the backup process. Most of the time the transfer charge is not in MB/s but kb/s,

  The NAS system is able to transfer 50 MB/s via an ethernet port matched.

  But time machine is a pain. Anyone has a better solution

  It is normal for a network backup. If you can make the first backup with a connection dirdct the incremental backups over the network so should not really be a problem

• Backup & Recovery in virtual environment

  Hello

  I need help to establish a good Backup & Recovery Strategy for VM-Ware with Oracle databases.

  Currently we use veeam backup the entire Virtual Machine during the night maintannce-window. On the virtual machine, we use RMAN to back up the databases, archivelogs fall under the machine.

  My problem:

  -If the virtual machine failure during the day, for example 16:00, cause of lost storage / instant failure that blocks the machine - I lose changes all day.

  So, where is the best place to save the logs to check-in during the day and how do I recover after an accident mentioned above? First step would be to recover the virtual machine with veeam, but subsequently? The database do not know what archivelogs were written, cause it contained last night?

  Thanks for your help.

  PS, we got the problem of the snapshot-crash on another machine, so it's really a thing that can happen.

  User106somethingorother,

  If you want to be able to recover in the case of the virtual machine / virtual disks are gone, you must ensure that your backups and archiving logs copied somewhere else.

  The users guide backup and restore (available at http://docs.oracle.com) would be the place to go to find out how to recover the database in many different scenarios, including one where you have lost direct control files and RMAN would therefore know about archiving logs is available.

  Kind regards

• Backup of the System Environment Variables

  How can I save variables on a windows system? The HYPERION_HOME and EPM_ORACLE_HOME system variables the same?

  If it's windows, then I find the best way is to either back up the registry or the part of registry, environment variables are stored in the registry to: -.
  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment

  So, if you go to start > run > regedit > HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment > right, click Export, save it out in a registry file.

  The registry can also be exported from the command line, for example to go to a command prompt and type
  REG EXPORT /?

  See you soon

• Backup plan for multiple servers ESX environment

  I'm looking for an automated process that can take pictures of my servers on an hourly basis and directly convert in ESX server.

  I love servewrs under Windows and Linux.

  Maybe I'm looking at this the wrong way b/c I am familiar with all VMWare products.

  But my main goal is to have shots at night and put them in ESX waiting to bring them back in line if necessary in a time of the disaster. But they should be powered off and replaced every day.

  Thanks in advance!

  The problem is not the tool. VMware Converter is the best tool for conversion, I know, but after hundreds of conversions, we can say that a conversion is not always "click and go".

  You CAN plan, but do not expect a result. PV2 process is possible but must be well thought out. Conversion depends more on the physical machine on the tool you are using.

• Using the base station airport ONLY as a backup, but is not a router

  Hi, I have a simple question that I can't find an answer. I want to use my Airport only base like a time capsule, and not as a wifi hotspot. I'm in a wfi environment that does not have any router, my wifi just to join a wireless network in my office environment. Previously, I worked in an office where I ran a cable DHCP in my airport base station and then he joined with wifi. Now, I just want to use the airport as a backup. Answers to this question involve disable wifi from the airport and hit an ethernet cable from the router to the airport base station. I do not have a router. So is it possible that I can get the device from the airport, make back ups wireless, all at the same time be connected to a wireless network? I'm guessing that the answer is no.

  Unfortunately, your proposal of "no" is correct.

  However, you could configure the airport Time Capsule (ATC) to create a wireless network (without Internet access) and save on the Time Capsule wireless.

  Of course, to do this, when you want to save, you need to log on to your 'normal' wireless network and connect wireless provided by ATC.  Once the backup is complete, then you'll need to sign the CTA wireless and log on to your normal wireless network.

  All things considered, it would be much easier to invest in a USB low price and connect the HDD directly on your Mac. In this way, you can stay connected to your wireless network normal and backups occur automatically.

• How can I backup my extensions if I update Mozilla

  One of my favorite Mozilla extensions is Super Start whenever I refreshed Mozilla in the past I lost and had to put up again.

• Satellite A660 - imaging the HARD disc using backup software

  I have an A660. I decided to do a system backup wholw with acronis image home for an emergency. My Quesntion is how are reserved windows make a picture of the toshiba backup partition?

  If I save all 3 partitions above I can restore them individually in case of need arise or I need to get all 3 drives together?

  I just support gelt upward the C drive will no longer Toshiba as its own MBR wrote. I don't mind also save the recovery tohsiba partition too much like its much faster than recovery DVDs.

  Please notify

  Hey,.

  I would recommend a full backup of all partitions. Toshiba recovery partition doesn't need a lot of disk space and recovery environment partition Windows is required, as far as I know, but there are also less disk space.

  With a backup complete all partitions, you are on the safe side and so you can ensure that you have the same settings after doing this.

  In addition if you want to restore the image, Acronis will ask you what you want to restore partitions. So it s always a good idea to make a backup of all partitions.
