VMware CBT (tracking changes block): ctk files and multiple backup systems?

Hello

We have 2 datarecovery running backups of the SAME virtual machines, but on the other day.

Later, we will have a dedicated backup solution, so we will use only 1 VDR + external backup system.

The external backup system use CBT too.

Now my question is: how CBT done when several backup systems require "that is the last blocks changed since the last backup?

I mean if I run Sunday, on the same VDR2, VMs and VDR1 Saturday to VDR2 always have only the changed blocks from Saturday to Sunday and the blocks changed the week lack? !!!

Could someone provide me a technique explaining the depth of the CBT mechanism?

Thank you

Yes, once a block is modified the corresponding location in the mapping file is labeled with the new changeID.

    Original title: activate the hidden files and folders. -Registry problem! Windows 7

    I had a meeting with a virus, which had a game with my registry so that I cannot view hidden files and folders. Whenever I click on "View files and folders hodden" and then click on folder options, it is by default to "do not show hidden folders and files". I've been browsing around, find people who give advice and I have seen some changes, but it STILL keep diverting back to do not show.

  • VMware - script the creation of the vm and the operating system installation process

    Hello.

    Trying to determine the exact steps to automate the entire process of creating a virtual machine, and install a linux OS (Rhel/Centos) in the virtual machine. I need to understand the steps to do it entirely from the CLI using scripts. I have seen a few sites that describe the basic process of creation of the VM, which appears to generate the vmdk file.

    I've seen nothing that shows what needs to happen to install the operating system in the virtual machine, in the CLI. This process should be auto/programming, so I can't use the GUI.

    I imagine that the whole process will have to call the process/kickstart file and start from that somehow, but I don't see how the elements fit. The goal is to then have a VM with the required OS/Apps that are then run / deployed by external users on their machines.

    If this process can work, then we can talk to a Council-expert/vmware on the next phase of the project.

    Answer that be detailing how to proceed, or point of item/sites on that would be great!

    Thank you

  • MSINWINPC - FBW files and restore, backup Dec 2009 concerns, concerns given PC June 2011

    Dear Sir/Madam,

    I did a back up of my data in December 2009 and I was wondering what is happening during a restore because I read that FWB is an extension for the backup file that is created. It compresses all the saved data and it incorporates in a single file so that it develops the files when performing a restore.

    What happened to my computer from my backup, it's that I had to install the Windows Vista Service Pack 2, which has consistently failed. To cut to the Chase, I contacted HP and everything they suggested the partition of hard drive HP factory reset factory reset, does not work properly and therefore all erased my disk hard but does restore all apps doing so my computer a brick. But since then, I contact Microsoft who kindly helped me with my cmputer and it is now working very well. (Thanks a lot).

    In any case, since the restore will be expanded I have 3 fear and would like advice on how I should go about restoring:

    1. the data amounts to 35.8 GB is currently on my external hard drive and free space on my drive hard is only 38 GB. If the files are all developed the 35.8 GB of data will take over 38GB?

    2. If I wanted to restore only certain files (I have a master's thesis I want to find and restore), copy the data to a file on my C drive before using the backup and Restore Center on my computer to find the file and restore?

    3. I'm worried that the old files that are saved can conflict with existing files I have been restoring my computer (like copying and pasting a file with the same name). I have to worry about this at all if I had to restore my backup data?

    Thank you

    Hi Densebrains

    Yes, the files get expanded after a restore of the backup is performed and the free space, you mentioned not be enough to restore the backup. When restoring files is performed on the computer disk files with the same name are replaced and you will get a prompt notifying replace it taking place.

  • Track changes by using find and replace

    I use Acrobat DC.  When you perform a find and replace function, is it possible to change? Thank you

    If that's the standard in the world of practice then the people in this world don't know what they're doing, I'm afraid.

    You should never modify a PDF file directly, unless it is the only possible option. You should always go to the original file format, edit it and then generate a new PDF from it. Do it directly in the PDF application problems. Even changing a single letter can cause serious problems with the layout of the file.

    You can convert PDF to Word using Acrobat, but it will never be perfect. The two formats are very different from each other.

    The quality of the result will depend on how the file was created originally. More consistent, it's the standard PDF better will be the result. The general rule 'Garbage In, Garbage Out' applies here. If the PDF file is a mess, if the results of export it to another format will be.

  • BlackBerry Smartphones BB Torch - deletion of files and multiple records

    I have over 150 photos in the pictures folder on my Blackberry Torch 9800 and after their import to my PC, I want to delete them from my BB to find memory and space... I can delete these photos one by a sequence of instructions in the Guide, but it is not logical to repeat this step 150 times and there must be a quicker way to go about it.

    What I want to do is to remove all the contents of this folder of photos in a single step. I looked on the BB Torch User Guide Ver 6.0 and in help for the BB Desktop Software and that you have not found the instructions on removing entire folders or multiple files in a folder in one step.

    Can someone direct me please some instructions or the Support page on the subject.

    Welcome to the forums! When you connect the device to the computer, you get three options, one of which is to connect in USB, or mass storage mode. If you choose this option, two windows will usually pop up, offers you the ability to manipulate files on your card or on your device memory.

  • Block Media Recovery and RMAN backup incremental level 1

    I read somewhere that block Media Recovery will not work if a database is backed up with 1 incremental rman. Is this true and if so is there a work around?
    I can't find it in the documentation of oralce.

    Concerning

    Hello

    Yes you are right, for the recovery block media, you must have full rman backup. Incremental backups are not used by block

  • How can I move my files and the operating system on a new hard disk on Inspiron 580 s.

    My hard drive failed Diagnostics recently and needs to be replaced.  I have since installed a new hard drive in Bay 2. I need to move everything from the old drive to the new drive and delete the old which is completed. So what is the best way to go about this?

    pjrl

    The simplest method, I prefer to install a replacement hard drive, is to clone the existing hard drive to the new, that will also transfer all applications and programs.

    You need an imaging utility, similar to True Image Home 2015.

    http://www.Acronis.com/homecomputing/products/TrueImage

    Acronis resize partitions transferred to match the size of the new hard drive.

    Hard drive manufacturers, also have their own free cloning software available, but it can be used only with their hard drives.

    First, install the new drive as the secondary and the image of the main hard drive in it.

    Immediately after the cloning, shut down the system, switch the data cable [SATA port 0] to the new disk, making the new master hard drive and see if the system boots properly.

    Start the system with only the new hard drive connected.

    Be sure to leave the original drive disconnected, until the new hard drive is working to your satisfaction.

    Before cloning a hard drive, make sure that the existing drive has no corruption or virus on it, because they will be transferred to the new hard drive.

    It will take a second SATA data cable, there should be a spare connector to SATA power inside the housing.

  • Change block tracking and comments defrag?

    If I understand correctly the data recovery Vmware uses modified block followed by spot the differences inside the VMs for each backup.

    How does this work with the guest operating system defragmentation tools? If there is a defrag job runs every night, not "change" a large number of blocks moving them simply?

    If for any reason you wish to defragment the virtual machine guest OS tools will indeed change you a lot of blocks.  If you use the block of tracking changes to perform differential or incremental backups, they grow.

    Usually when your virtual machines sit on VMFS recommended of is not to defragment the guest operating system.

  • Barracuda Backup - changed block tracking does not properly

    Greetings,


    What is going on:

    In a Word. I am trying to solve a problem with a backup of Barracuda and the block change tracking.  It happened from the server (as well as the Barracuda 190) has been installed long ago.


    Long story short. With CBT activated (changed block Tracking) Barracuda is supposed only to save "disk blocks has changed."  She doesn't at the level of virtualization, no comments. In my case, it's back up about 124 GB every night. (2-3 hours of the device), and then from 10 to 12 hours to move to the cloud.


    MY SYSTEM:

    There is only 1 VM (comments) on the host computer. The two drives on the computer virtual (comments) are a 60 GB drive OS (SBS Server Essentials of 2012) and 100 GB data disc.  Both have 33 GB used on each of them (66GB total).  Changed nightly expected data should be an absolute maximum of 6-8 GB each night much less commonly.

    Nothing about the host OR virtual machine (guest) server is added to the 124 to 128 GB that says Barracuda is saved.


    HOW CAN I KNOW IT IS NOT WORKING PROPERLY? :

    I have two other systems in separate buildings that work as expected. So, I have an A, B, C comparison.  A and B are working properly. C is not.   They are all the same hardware platform HP ML350p Gen8. They are all configured as except for the sizes and quantities of drives in the RAID 5 group. They are all ESXi if the one in question is on 5.1.0, and the other two are on 5.5.0.


    Not that it matters, but the guests on these systems are: host a system has a brand new 2012 R2 STD Server .  B host has a system "autonomous converted" SBS 2011 .  C host system has a new 2012 Essentials server.


    WHAT DID I TRY? :

    I made sure all the settings in the settings have CBT enabled and set to true.  I tried to re - set up a new selection of backup within the Barracuda 190. I made contact with technicians Barracuda of 1st and 2nd level support on several occasions. Initially, they said it was a problem of snapshot.  I looked the better shots I knew how (I'm a noob, but I got some great info here about how to look at snapshots and VM running of stains from p_hall), then when they couldn't tell me where in the phase of snapshot, it was, they said 'it works as expected. , (and even if I have only 66 gb of disk space used on a total of 160 GB on reviews) "isn't really 125 GB backup every night. It just reports that it is.  Still my bandwidth says otherwise.   WHAT !!!!!!!!???????


    Finally, I took the well-known Barracuda of the FD (from system B Barracuda) and put it on the DP (in lieu of system C Barracuda) for a few nights.  He behaved exactly like original C system Barracuda. He supported 128 and about 147 GB the first night the next two nights.


    See attachment for samples of the reports at the end of last year backup 3 systems. Yes, they are older, but the results are the same.


    Any suggestions on how to fix this?  Thank you.


    I want to mention that my problem is now solved. Still using CBT, my nightly backups are more in line with what is, was expected.  Instead of backup 128 GB EVERY night (I still don't know whence the figure), I support anywhere from 3 to 15 GB per night.  A difference.

    The problem has been resolved with a simple upgrade to ESXi 5.1 to 5.5 upd 2.  No other changes made.

    Wouldn't be an accurate assumption that unlike VM KB 1020128 that CBT is, in fact, NOT compatible with the ESXi5.1?

    I'll be the first to admit that VMWare is not my forte.  That said, I'm rather discouraged that there no one answer to my post with suggestions.  I post in the wrong place. Poor choice of title/key words? It was poorly made? Unintelligible?

    According to me, that I was very thorough in my research on the issue.  I found this which mentions clearly the CBT is supported in ESXi 4 and more.

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1020128

    I was diligent in troubleshooting up to the point where I pretty much dismissed everything except the host operating system.

    Not knowing how big the community is, I would think that there is someone out there with my exactly the same problem, or at least there was someone out there who was successfully in 5.1 ESXi with CBT on a system of Barracuda.

    I am open to any suggestion that may make future messages/questions to gather more responses.

    Thank you.

  • Windows 10 will change my current setup of the operating system on files on the SSD HARD drive and program/user?

    Way back when I upgraded my main drive to a SSD, I used the following to put all the files of program/user on my HARD drive.  My questions are:

    1. What are replaced to the default settings?

    2. If so, what measures are needed to reach my current setup?

    d:\Users d:\ProgramData

    I would advise against using a script that in the beginning, because some people have had the tough get windows to read files that are not where they are supposed to be.

    For applications and other personal files, 10 Windows offers a similar feature in the settings.

    Program files (and the similar system attributes) should probably be intact until the symbolic links (which redirect Windows when he tries to find the file) running again. The application of this article did not work because Windows 7 was new, and equivalents of the command prompt (how I got to this topic) do not work.
