• VCB backup - Linux guest OS

  Hi all

  I use 4U1 ESX and VCenter4U1, then a virtual server, Redhat 5.2 Ent 64 bit installed in the virtual machine environment. I want to use a LAN free backup for this environment. I'll use backup VCB as one of the solutions.

  A server, Windows 2003 64-bit, it will be like a virtual Center and a proxy server.

  My question is:

  I go to the file/backup directory in the virtual machine (guest operating system Linux). How do I achieve this?

  Thanks in advance...

  No reason to fear. Really, don't you think that I am wanting to perform all these steps manually? Everything works automatically and observing each step isolated, it turns out that to be really simple.

  1. create a RDM

  2. the mount RDM VDR and format

  3 backups

  4. stop VDR after closing window of backup (with vCenter annexes)

  5. start Backup-To-Tape device to time there (let's say it's a virtual Windows machine)

  6 mount RDM with driver for ext2/ext3 filesystem (www.fs-driver.org)

  7 use a third-party backup software to save the ROW content on tape

  8. turn off Windows VM backup is complete

  9. start VDR to time z

  I use this process for a few weeks now and I have already tested the recovery of a band on the disc and VM disk. No complaints

• Cloning of DB on another tape RMAN backup server

  RDBMS version: 11.2.0.2 on Solaris 10
  Media management layer: Netbackup v7
  
  I did only the tape backup. I never did restore, recovery of a band.
  
  We have a production DB named NEHPROD currently running on the server qualmh214. Every Monday morning a RMAN full backup to NEHPROD is taken on the Strip.

  Production server : qualmh214        DB Name:NEHPROD
  ----------------------------------------------------------------------------
  
  run
  {
  ALLOCATE CHANNEL c1 TYPE 'SBT_TAPE';
  SEND 'NB_ORA_CLIENT=qualmh214,NB_ORA_POLICY=qualmh214_rman,NB_ORA_SERV=qualmh238,NB_ORA_SCHED=Daily';
  backup database   FORMAT 'NEHPROD_%d_%U_%t.rbk' tag='NEHPROD_full';
  }

  I need to create a Test database in another server (qualmh199) by restoring directly since the full backup from NEHPROD Ribbon.
  
  
  Of qualmh199, how can I connect to the server to tape media?
  
  Even if I connect to the server to Tape Media, how can I have access to backups on tape to another DB? In the block RMAN run, you can specify a name of the comic. Right?
  
  Although I have access to the backup of the DB, how can I specify full backup of Date to which I need to use it to restore?

  Of qualmh199, how can I connect to the server to tape media?

  You must assign channels to strip & need to mention the NB settings like example below.

  in the RMAN script
  ALLOCATE CHANNELS CH1 DEVICE TYPE SBT_TAPE PARMS 'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64 ';
  SEND "NB_ORA_SERV =, NB_ORA_CLIENT =';"

  Even if I connect to the server to Tape Media, how can I have access to backups on tape to another DB? In the block RMAN run, you can specify a name of the comic. Right?

  If the libraries are installed and you able to perform, you can go for the double or single RMAN restore database. You can also mention other DB names

  Ex: duplicate target database to 'test ';

  Although I have access to the backup of the DB, how can I specify full backup of Date to which I need to use it to restore?

  You mention the tag if you use RMAN restore.

  The duplicate database is restored. It remains only the archivelogs.
  If I try to backup all archivelogs again and to run the double once more,
  The data files already restored are underwritten, or RMAN ALL restart again, RESTORE

  The database has 600 GB. So, if I start again, it's a big problem.
  
  What can I do to fix this?
  
  Thank you very much!!!

  First thing is that you can make two copies because the database is already mounted...
  Why you want to restore again?

  Just start MRP and post if no errors.

• Removed garage iCloud device missing Band song

  Hello.

  I wanted to download songs from my iPad to the iCloud for further editing in Garage Band. I managed to download a few songs, and then I found it too slow and selected more songs to download at a time. I slid down and exploited the cloud menu and some of the songs have disappeared from my camera without notice.
  I checked once more and realized that when a song is selected that was already uplodaed, the command "load the song to iCloud" changes to "remove pieces of iCloud".  So, I learned that I accidentally deleted some songs from iCloud, OK, but why they disappear from the device?
  The support site says that "when you delete a song, the song remains on your current phone, but precipitates iCloud and your other devices." but this isn't the case, these songs have disappeared from the device, and I can't see any recovery or recycling facility in iCloud is...   Any chance to revisit these songs? Thanks for your comments.
  Andras

  This just happened to me. The song disappeared. All this hard work!

  When I bought my computer last year, I couldn't create a recovery disk, I tried so many DVD, but there's an error in the end every time! : s I dropped the banding I'll ever need...
  Hem hem, now I would like to (reformat?) restart my computer to make it clear to all my HD programs, docs and other...
  Yesterday I bought an external HD (1 TB) and I would like to create the famous recovery file in my new product...

  Is this possible? How can I do?

  No, it will not work. HARD disk image is designed to be used from the second partition only and only with the factory settings.
  If you install own OS you will lose F8 option to fix my computer.

  Well I had this phone two days ago and he used once after installing fire fox and my mobile to wide band of the driver and going to start and find it of going to happen.

  I tried SafeMode (three) and repair and all I got was a screen black with the cursor upward where it should have been a language screen (I used the recovery disc supplied with the notebook) so anyway, after finding out that I wasn't going to be able to fix it, I tried to install , but of course, this does not work, or so I put my XP 64 bit OS on and has perfectly worked, then I updated (using my own upgrade windows 7) and that works fine no problem, so I tried again with the original windows 7 comes pre-installed on the hard drive on the laptop and everything went find until she starts the installation of the driver or updates (I not 100% sure on this but it or after the installation of face recognition.

  Then it stops it of self down and boots back up to automatically restart and asking me if I want to repair due to a bad start, so I did the repair boots back to the top and still says I need to fix and can't find anything wrong and carries on in this circle.

  Now, I was told it could be the registry or there is a problem of graphics, I get pretty tired of having to install/reinstall/format this laptop.

  So if there is anyone who knows of what is wrong or what to do or whether it should be returned to fix, which will be very useful.

  I thank everyone in advance.

  Happy new year :)

  Hello

  Well, I think that it of really difficult to say what is the reason. Maybe the recovery disk is noisy or the files corrupted it.

  At the moment, I can t imagine what it s a hardware problem because other windows drive work properly.

  In your case, I would try to install Windows 7 from a Microsoft disc and then see what happens. If it works properly and that you can install all drivers & tools you need to order a new drive Toshiba Recovery directly.

  Good bye

• Spectrum 360 x: Intel (R) Dual Band Wireless problem - unable to connect to WiFi

  Hi, I have problems connecting my laptop to the Internet. The laptop even can't detect wireless networks (despite other devices being able to do), even if it wasn't a problem beforehand. I have troubleshooted and received the message "card Intel (r) Dual Band Wireless-N 7265 problem driver - or related to the material." so I tried to search through the forums. Unfortunately, I couldn't find a solution other than to go to the Device Manager. Under "Network adapters", the Intel (r) Dual Band Wireless AC7265 reports a problem (he has a!). It indicates the status of the device is "this device cannot start. (Code 10). {Operation failed.} The requested operation failed. "Before that, I remember it to be 45 Code, something about the material being not connected.
  
  I've been to events where it says that the device has been installed but also that "Driver Management concluded the process to install the driver... (..) with the following status: 0x0. »
  
  I think that this problem was caused yesterday when I closed my laptop - I think it was set up the device / through a kind of update when I forced stop it (the screen was black and I didn't know at the time it was the configuration) and that's when I had problems connecting to the Internet. When I went into Device Manager, it says just something on the device requiring an additional installation, but after reviewing all possible solutions on the forums, it has become a Code 10. I tried to update the driver software, but it says ' window has determined the software driver for your device is up to date ", restart the Internet modem, reboot the laptop, the laptop everything, ranging from recovery reset - all with no avail. Sorry for the very long and detailed post, but if someone could please help, I would appreciate (this is the only laptop I currently and about a week). Thank you!

  Hello:

  Please provide detailed information.

  Here's what I recommend.

  Transfer the driver on your PC with a usb flash drive.  Do not run the file again.

  https://Downloadcenter.Intel.com/download/25603/Intel-PROSet-Wireless-software-for-Windows-10

  Go to Device Manager and right-click on the problem Intel wireless network adapter.

  Select uninstall and check the box uninstall driver.

• DiskPart / software RAID - disaster recovery

  Hi guys,.

  I have a VMware VM running Windows 2012 R2 DataCenter Edition. I tried to clone a DR test for one of my clients. I was able to start the virtual machine in Recovery Mode and use diskpart to assign the appropriate drive letters, etc. (it is a software RAID 1 mirror) after importation of disks (they appear as foreign at first) and the output.

  I have tried a number of tools - however, when system - bottom line - restarts looks disks back to being at reboot - what makes the system unable to boot properly.

  Any ideas on how I can get the data from partition table that I put in diskpart persist beyond a reboot?

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• 15 t-n200: replacement hard drive dead: what should I buy HP replacement, or everything will work with recovery media?

  I have a HP Pavilion 15 t-n200 laptop computer running Windows 7, 64-bit.

  The computer got extremely slow and work stoppage. HP diagnostic indicates a failed hard drive, and my warranty has expired. I DO NOT have the recovery media.

  My question is this: if I buy the recovery media for my HP computer, should I also buy HP hard drive for it to install correctly? Or can I just simply buy a HDD from a local retailer and use HP recovery support (and the certificate of Authenticity on the back of Microsoft) to reinstall WIndows 7?

  Some people suggest that it will work very well, while other members of the forum here have talked about issues and something of tattoos on the hard drive or the Council.

  Thanks in advance to anyone who responds!

  Hello

  No, you don't need to buy the HP's HARD drive, you can buy anywhere, but please use the same band (normally from Toshiba, but please check the label) for the compatibility and capacity or more.

  Kind regards.

• Quick recovery 6.0 direct support of archives to the tape library?

  Hello

  We are running Appassure 5.4.3 with a core off site for replication. We are planning to upgrade to fast food but want to see if it supports now archiving to a library of tapes for an extra layer of protection.

  The current process of archive on disk is slow disbelief and takes a huge amount of space.

  fast recovery 6.0 does not support the band live archive. However, it supports archiving directly on several environments of the cloud (Amazon S3, Microsoft Azure, stack open [suppliers] and RackSpace Cloud Files). In addition, it is possible to attach an archive (including an archive of cloud) to a core as a read-only repository (no import archive necessary). I don't have details about costs. However, according to some customers, I talked, cloud storage, especially when using scheduled archiving (with the/incremental option selected) and the new archive attached characteristic, is an option that is worth exploring because it offers a cost/quality ratio. Please note that, by its nature, an archive on tape must be imported to a core before being accessible, which can be a lengthy operation.

• Photoshop questions color bands appear in the PSD files?

  I hope I can get help with a problem I've had with Photoshop or my PC.   I use Photoshop to make the illustration work.  My problem is that some of the work files I've saved get magenta or green strips through them when I reopen it.  This has happened more recently.  They are not a few strips of color, it's like a bunch of a part of the illustration is projected onto another area, and this band discolour the part of the illustration it is superimposed on.    Files of closing and reopening will not fix the image, or don't restart PS, but restarting the computer succeeded in restoring the images, however, corruption continues happening randomly with other files.   Anyone know what is the cause and what can I do about it?    I tried to disable the graphics processor and change the drawing to basic mode, etc.   I don't know if the problem is from photoshop, my pc or my graphics card. So far, only to restart my PC will correct the image, but I really want to solve this problem, so he continued to occur.

  Thank you very much for your time!

  Here's an article on it: corruption - file recovery corrupted Photoshop cs6 - Super User

  Outside the hibernation cause problems, perform a routine maintenance, disk cleanup, check the disk Defragmention and of course as suggested, turn on the history of the file or the shadow copy.

• A few Questions about the manual recovery

  DB version: 11.2.0.3.0
  Platform: Oracle Linux 6.4

  I'm not an expert in recovery.

  We had a level of SAN cloning of a RAC database. We store online Redo logs in the diskgroup RL_DG and ARCH_DG diskgroup Archive redo logs.

  After the plan of SAN cloning (EMC BCV Synch), we tried to start up of the DB using srvctl start database-d < MyDBName > and we got the following error message.

  CRS-5017: the action "ora.msblprd.db start" resource has met the following error:
  ORA-01113: file 4 should media recovery
  ORA-01110: data file 4: "+ MBL_DATA/msblprd/datafile/users.271.803502221".

  We realized that a lot of data (not justs users.dbf) need recovery files. Thus, we tried to run to RECOVER the DATABASE. But it errored out. So, we ran to RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL ;  command.

  Attempts above did not work because oracle was looking for the archived logs that was not present in ARCH_DG, RMAN has backed it up to the band and issued "delete entry".

  But I have a few basic questions.

  Question1. Why the command RECOVER DATABASE fail with ORA-01610?

  Question2. RECOVER the DATABASE and recover database using BACKUP CONTROLFILE until CANCEL commands will look only archivelogs not redo logs online. Right? I understand that this database will try to retrieve media by the application online Redo Logs when the STARTUP OPEN command is issued. Right?

  Question3. In the command RECOVER database using BACKUP CONTROLFILE until CANCEL that BACKUP CONTROLFILE, we refer to the?

  Question4. What does AUTO option? in calls it "Specify log" as I have indicated above in red

  Question1. Why the command RECOVER DATABASE fail with ORA-01610?

  Oracle has detected that the controlfile was 'old' (for example had a low point control #) as the database.  If she recognized the controlfile as a BACKUP CONTROLFILE.  You make a full recovery, that can be done if the real current controlfile and redo log files are consistent and 'newer' database in a DATABASE files to RECOVER normal.

  Question2. RECOVER the DATABASE and recover database using BACKUP CONTROLFILE until CANCEL commands will look only archivelogs not redo logs online. Right? I understand that this database will try to retrieve media by the application online Redo Logs when the STARTUP OPEN command is issued. Right?

  N ° N ° (in the normal case) the RECOVERY DATABASE can automatically identify the online redo log file must be applied to make a full recovery.  In your case, Oracle has already tried an incomplete recovery.  It will have to be provided (or be able to AUTOMATICALLY generate) the archivelog file names.  Apply of Redo Log files online only happens to a recovery of Instance - a START after a crash or abort.  Your case is a Media Recovery (again because of the backup control file).

  Question3. In the command RECOVER database using BACKUP CONTROLFILE until CANCEL that BACKUP CONTROLFILE, we refer to the?

  The controlfile you have on the disk is 'old' - it is recognized as a backup controlfile.

  Question4. What does AUTO option? in calls it "Specify log" as I have indicated above in red

  (in the normal case) Oracle can generate the name of the 'next' archivelog file based on the last archivelog applied and the log_archive_dest log_archive_format and.  Given that you had not applied all archivelog and yet, he would not be able to generate the next archivelog expected - this happens also in the RAC recovery where it can generate automatically the archivelog next to (for example) wire #1 file name because the archivelog to thread #1 has been applied, but can still generate automatically for wire #2 until an archivelog was applied.

  You will also notice the inadequacy of sever between the online redo log header and the newspaper WAITED

  > archived log contains sequence 16107. 16085 sequence required

  This means that the data files is much older than the online redo log. Given that your ad doesn't show 22 redo log groups, it is likely that the snapshot log redo DG and DG database files don't match no - the second is much older than the first.  You need an archivelog to apply, not the online redo log.

  Your query on V$ LOG and V$ LOGFILE should always optimasation THREAD # (when CAR is running) and SEQUENCE # (each Thread has it's own sequence)

  You can also view your alerts log. This could indicate that Oracle was trying to recover the datafiles Fuzzy - what would happen if your snapshot was taken without the database in BACKUP mode.

  Talk to EMC and Oracle support for the good tips on how to make a snapshot backup of an Oracle database.  Otherwise, you'll be toast when you need to perform a recovery of real Production database.  I suspect that your DGs and EMC volume is not configured properly to create synchronized instant backups.

• Question on recovery

  DB version: 11.2.0.4

  OS: Oracle Linux 6.4

  We have a Level0 Sunday backup and an incremental backup of L1 for the remaining days.

  1 - Sunday-> level 0 backup (23:00)

  archlog1

  archlog2

  archlog3

  .

  .

  .

  archlog235

  2 - Monday-> level 1 backup (23:00)

  archlogX

  archlogY

  .

  .

  .

  archlogn

  3 - Tuesday 08:00

  So, we have a backup of L0 Sunday night and a Monday night L1. The next morning of the day (Tuesday), at 08:00, we lose our data base.

  Question1. If I want to completely recover the DB up to Tuesday 08:00, the following should work. Right?

  Sunday L0 backup + Monday backup L1 + logs archive generated after the backup of L1 of the night from Monday to Tuesday 08:00

  Question2. If I want to make a Point in time until Monday 16:00 recovery, I can do the following. Right?

  Backup backup of Monday night L1 + L0 of the Sunday (. ie) I don't need the Ark of newspapers from L0 Sunday evening till Monday 16:00 )

  We currently have a debate on how long we should keep the backup of archive logs in the backup media (Data Domain).

  > Sunday backup L0 + Monday backup L1 + logs generated after archiving backup L1 of the night from Monday to Tuesday 08:00

  Oracle would need the ArchiveLogs in the * beginning * of the backup of the L1.  The L1 backup takes more than 1 nanosecond to run and an inconsistent backup (as is the backup of L0).  So, so that the backup of the L1 be usable, Archivelogs early in the L1 backup are required.

  > Question2. If I want to make a Point in time until Monday 16:00 recovery, I can do the following. Right?

  > Backup backup of Monday night L1 + L0 of Sunday (IE. I don't need the Ark of newspapers from L0 Sunday evening till Monday 16:00)
  Your recovery Point is * before * the backup of L1 of Monday night.  Monday night L1 backup is * after * the Recovery Point.  Monday night L1 backup should not be used, is unusable, is incorrect for a recovery from 16:00 Point Monday.

  You need backup Sunday as well as all the time sauvegardΘ ArchiveLogs L0 L0 began until 16:00 on Monday.

  As Ed says, Oracle RMAN automatically manages and identifies the backups are needed.  You must be "on the photo" only if

  a. you use RMAN backups to disk

  b. use then a method non-RMAN to copy from disk to tape

  c. you then delete the backups on disk

  In such a scenario, RMAN attempts to search the archivelogs on disk and the appropriate safeguards. You need to manually restore the correct backuppieces and the band on the front disc archivelogs RMAN can use.
