Write backup directly to a tape drive - how?

Then... connected on one of our hosts ESX is a scsi tape drive.

A VCB based a host file-level backup works terribly slow (400 - 500 MB/min) and an agent based at the level of the backup files works licensing costs (although it is much faster to nearly 3 GB / min... same servers).

I read that it is possible to output a right TAR tape... without any sort of proxy backup software.

I know VERY little of Unix systems... If I wanted to schedule a task of all night for all my virtual machines TAR, how would I go to do?

The process that I realized it would be to create a script that:

(1) get the tape drive (whenever I try to "climb" I get the error that it is not a block device)

(2) Flash virtual machine

(3) creates an archive of said machine virtual (I think that's what they're called?) with the output piped in the tape drive

(4) the virtual machine unsnapshot

(5) remove the tape drive (or go back to step 2 and repeat with another virtual machine)

Hello

In the penultimate chapter of the book, VMware ESX Server in the enterprise is such a script. So yes it is possible. I did it several times. I think I have a separate backup/VCB proxy server would be much more effective for you. You can then use existing free and fresh backup tools to provide a backup solution. See http://vmprofessional.com/index.php?content=esx3backups for a comparison of the tools. With compression you have much more space on the backup host to...

  • fibre channel tape drives

    What is the latest on connecting broadband fiber channel led to virtual machines? Is it supported? Otherwise, what is the best way to use a tape drive with ESXi/vSphere fiber channel?

    I use Acronis Virtual Edition in a VM and I'd love to Acronis can directly see the tape drive.

    Looking for suggestions.

    You may be able to make it work, but there are only a few cards that are same experimentally supported.  Couple that with a band CF device unsupported, and personally, I would not base my strategy of backup around it.

    Thank you.

    Yes it's available by design. You have to configure the NAS with the role of mediaserver and add a 2nd point of attachment to the device. You can then create calendars that limit to those fixing points. Allows you to share all the drives between all media servers.

    For the robot, I let the server admin to do that, just tape devices were mapped to the time. Controlling Robotics is a light enough task.

  • How to use the SDLT tape drive in the guest OS VM

    Dear

    now, I have HP DL380 G5 Server running windows 2003 Ent. with bus adapter host SC11xe PCI - E HP which directly connected tp SDLT Tape Drive as backup server and use for the backup operation.

    I want to move the physical backup to host vmware server and EMC AX4 allows you to have a backup online and allows you to take backup offline, SDLT tape drive

    Please let me know how to do this.

    I have a G5 DL385 (AMD of the DL380 version) with a DLT3.   I use an Adaptec 29320LPE, appearing on the compatibility list.  We plugged a HP Ultrium 920 changer using the 'old method' SCSI passthrough.  We bought the Adaptec card, because we used initially ESX3.5.  We are now on ESX4.0, but for various reasons, the configuration left the same, so I have not tried with VMDirectPath I don't know if it is possible to use the SC11ex card, but if you arrive VMDirectPath at work, it seems then you need another SCSI card.

  • My question is: is there an approach appropriate to where and how files should be created and arranged, except directly in your main drive, in my case C:?

    I recently had a hard drive replaced requiring a new installation of Windows 7. When I went to get the system in place, the guy who set up Windows told me that he created the user directory specifically in a way so that new files to be created in a Documents folder that was created under the username. At least that's what, in my view, said.

    In any case, I always create new folders and their subfolders under Local C: drive.  My question is: is there an approach appropriate to where and how files should be created and arranged, except directly in your main drive, in my case C:? Thank you for your help.

    Windows 7 has been designed with the intention that user folders and files will be store in one of the folders under the users, that is to say the Documents, photos, etc.

    It is not recommended to store in the root, i.e. C:\ directory.

    If you have any other disks or partitions, you can store what you want there.

  • Support ESXi 5.0 host FC connected tape drives in the virtual machine running symantec backup exec 2012

    Dear Experts,

    We recently purchased C0H19A: StoreEver HP 1/8 G2 6 - LTO Ultrium 6250 CF TapeAutoloader. The purpose is to backup of VMS data, I mean selected data in virtual machines, as for the exchange of data bases email for server accounts database SQL server etc.. We have a full VM backup plan, so using symantec backup exec software.

    We have this configuration:

    -TWO DL 380 Gen8 servers (running UPDATE2 Esxi 5.0), both servers have not all SCSI ports

    -One SINGLE HP P2000 G2 MSA FC Dual Cntrl storage

    -TWO HP SN6000 12 - pt Windows Pwr FC switch

    -HP ADF

    All them above are related to the CF. Symantec backup exec 2012 is also installed on Windows 2008 R2, which is a virtual machine.

    But now, we are unable to see the tape library autoloader through the virtualization layer in the device of machine Manager virtual backup exec. Reading on internet, I also found some details that connected FC tape drives are not supported by the Esxi hosts. We are really stuck in this situation, all the solutions to this. I also read the article from vmware saying configuration for Esxi 4.0 FC tape drives and later versions

    Installation of a physical server windows with Backup Exec 2012 and HBA and connected to above switches FC is the only way to see the ADF? Even after reading articles on the internet, I'm not clear, please guide what solution I have now to get this thing going, I really need to find solution to this.

    Waiting for answers.

    Kind regards

    Hello, I'm a Backup Exec support engineer and yes the method supported is only by connecting the tape drive to a server of physical media.

  • Through host SCSI tape drive to the virtual computer with the backup software installed in the comments

    Can I attach an external SCSI tape drive to one of my hosts, and then add it as a device in a virtual machine.

    I want to use backup exec on a virtual machine, rather than having to have a separate physical server to attach the tape drive. I realize that I wouln't be able to vmotion the guest but as its only going to be a backup machine I am happy with that.

    Thanks in advance,

    Yes is possible.

    I have a Dell TL2000 with a dedicated SAS card and it works (not faster than in a real environment, but works).

    You add the SCSI ID of the tape (and the library, if any) to the virtual machine.

    Or, if your hardware can he take charge, using VMDirectPath and give the card on the virtual computer.

  • How can I prevent Windows Update to write data to my external HARD drive

    I have Windows XP running on a controller NI PXI-8106. On this same controller, I have two mapped drives.
    1 C drive where Windows is installed
    2-external SATA drive mounted in RAID0 used to save sensitive data in our application.

    We discovered that Windows update has written files to disk external DRIVE instead of the local drive as we would expected. What could I do to prevent this. It is very important for us, given that the RAID0 data should not be upset by any means. We cannot update Windows to write outside of the C: drive.

    I look on various forums and it seems that I'm not the only one in this situation where Windows Update writes data to an external HARD drive, but I have not seen anywhere a solution to avoid this, in addition to unmaping the drive.

    During the installation of updates, Windows Update downloads the installers (only) for updates to the drive with free space available. You can either disconnect the external drive when you need and/or free up space on, for example, your boot drive.

  • Are there files in some tape drives?

    DB version: 11.2
    OPERATING SYSTEM: AIX
    MML: Symantec Netbackup 7.1

    I worked only with front based disc backups.

    My question is not specific to Netbackup. I just want to know how if there are directories in tape drives? Or does a wholesale directory where all the backup files are stored?

    After you have configured netbackup, if I run the script below
    RUN
    {
    ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
    SEND 'NB_ORA_CLIENT=emprd218, NB_ORA_SERV=hewmast193'; 
    BACKUP DATABASE;

    SEND 'NB_ORA_CLIENT=emprd218, NB_ORA_SERV=hewmast193'; 
    BACKUP ARCHIVELOG ALL ; 
    RELEASE CHANNEL ch00; 
    } 
    In which directory in band will be stored all these backups?

    If it was from disk, from the FORMAT parameter, I knew where all the backupfiles are stored.
    CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/u04/backup/ora_df%t_s%s_s%p';

    Greenish salvation,

    I just want to know how if there are directories in tape drives?

    There is no inventory on the tape. Ribbon tape and disk is disk. (But to be honest, a tape backup can be used to restore files and directory structures).
    Make direct backups to tape you can use:

    BACKUP DATABASE FORMAT "ora_df % t_s %%p s_s.

    Backup will software an internal ranking system is in service a restoration of the channel.

  • the hard drive of my computer is purchased full.i a drive.how external hard change outside the primary disk so I can download music easily?

    the hard drive of my computer is purchased full.i a drive.how external hard change outside the primary disk so I can download music easily.right now my external backup just my computer that isn't doing me good

    original title: external hard drives

    You don't want to change your external drive to your main drive.

    You can move your music files on the external drive - or you can move other data on the disk to make room for your music on the internal drive.

    What applications do you use to play music?

    As described in the first link below, you can move your full "My Documents" folder on the external drive.  Alternatively, you can simply move your music files.  If such an arrangement would give you a satisfactory performance, however, depends on how your external drive is connected (for example, USB 1.1, USB 2.0, USB 3.0, eSATA, Firewire, network) and other hardware features of your computer.

    Not all of the following conditions will be applied to you, but some of the tips can be useful.

    There are a number of things you can do to- temporarily - free up disk space.  The only real solution, however, is to get a bigger internal hard drive.   You can move the data to your external drive, but if it's the data that you use frequently, slower access times may annoy you.  Therefore, I do not recommend that you move your My Documents folder in its entirety on the external drive, but you can certainly do this by following the related instructions.

    • You can run Disk Cleanup (start > run > cleanmgr > OK)
    • You can reduce the size allocated for the restoration of the system to about 1 GB (right click on desktop > properties > system restore > settings)
    • You can disable hibernation (if you don't use it) (right click on an empty spot on the desktop > properties > screen saver > power > Hibernate)
    • You can disable the indexing of the drive, which will also speed up your computer a bit (http://lifehacker.com/031440/turn-off-indexing-and-speed-up-windows-xp)
    • You can reduce the size of your Internet browser cache (depending on the browser that you use)
    • You can remove most of the $NTUninstallKBxxxxxx files $ following the directions here: http://windowsxp.mvps.org/Hotfix_backup.htm (read the warnings in the gray box first)
    • See also:

    " How to recover disk space on Windows Server 2008 and Windows XP computers? ."

    " Forty ways to free disk space ."

    But none of these answers you will earn really large amounts of space for very long.  The term solution time is a bigger hard drive.

    In the meantime, download and run JDiskReport, that will show you graphically what files take up more space and seem to so indicate what files you must move it to your external drive.  If you want to move an application, you will need to uninstall and then reinstall it specifying your external drive as the installation location.  You can not simply move the files.

  • Error 39 XP on dat72 tape driver code - cannot install the driver

    Help! In an IBM computer running Windows XP Pro SP 3 I am looking to replace a defective DAT72 IBM (Seagate) drive with another band DAT tape drive - the replacement drive came from Dell, but it's the exact same Seagate drive. For some reason, the new tape drive is first detected as a Seagate drive, then askes for a quantum qdatwin.sys file - the former disc one driver IBM). I downloaded the latest drivers for Quantum, Dell and IBM, and any driver I install I get the same message that "Windows cannot load the driver for this hardware device. The driver may be corrupted or missing. (Code 39) ». I should mention that when I started this process trhe CD player had mysteriously disappered. I had the Code 39 error on the CD player as well at the time - but not on the tape drive. I went to States support of info on it and choose the "have them fix it" (or whatever it is) and it did fix (problem of CD which is). Now it seems I have the same problem with the Unwinder - but I can't find any info on how to fix this. Also, I tried resdtorign the computer at a checkpoint before the problems started - not question how I chose, I get the same error Windows cannot restore to the restore point - choose another. I tried 7 different restore points with the same results. I ran a full antivirus scan who come clean. Furthermore, I use Acronis backup software that does not all drivers of his own band - it relies on the drivers for the tape drive. Everything worked fine for a good year before it happened. At the end of my rope here.
