• Backup process takes about 17 hours, which includes the audit of 18 GB of data

  I backed up my system Windows XP Home edition on an external hard drive with the NTBackup utility system.  This process takes about 17 hours, which includes the audit of 18 GB of data.  Is there a problem with backup on my system causing this slow time of execution?

  Now, I created a disk image of my system using the NTBackup utility of the system from the installation disc, and also, it takes about 17 hours.  There may be some kind of hardware problem.

  My computer has installed in USB1 and translates into a slow backup.

  NTBackup is one of the worst possible for the backup options (as you can see from your experience). I can recommend a far superior alternative. But first, you must let us know what your goal is:

  1. regularly back up data ONLY (for example Word documents, photos, mp3s, etc.)?
  or
  2. make incremental copies perfect bootable on your system, including all service packs, updates, installed programs, etc. (and possibly your data as well)?

• Poor ESXi 4 NFS Datastore Performance with various NAS systems

  Hello!

  In testing, I found that I get between a half and a quarter of the e/s inside a guest performance when ESXi 4 systems connect to the using NFS data store if the clients connect to the exact same NFS share.  However, I don't see this effect if the data store using iSCSI or local storage.  This has been reproduced with different systems running ESXi 4 and NAS systems.

  My test is very simple.  I created naked CentOS 5.4 minimum installation (completely updated 07/04/2010) with VMware Tools loaded and the creation time of a file of 256 MB using jj.  I create the file on the root (a VMDK stored in different data warehouses) partition or a directory of the NAS mounted via NFS, directly in the comments

  My crucial test configuration consists of a single test PC (Intel 3.0 GHz Core 2 Duo E8400 CPU with a single Intel 82567LM-3 Gigabit NC and 4 GB RAM) running ESXi 4 connected to a printer HP Procurve 1810 - 24 G, which is connected to a VIA EPIA M700 NAS system running OpenFiler 2.3 with two 1.5 to 7200 tr / MIN SATA disks configured in front of software RAID 1 and dual Gigabit Ethernet NIC.  However, I have reproduced it with different ESXi PC and NAS systems.

  This is a release of one of the tests.  In this case, the VMDK is a store of data stored on the NAS via NFS:

  The first dd is a VMDK stored in a connected via NFS data store.  The dd ends almost immediately, but the synchronization takes nearly 40 seconds!  It's less than 7 MB per second transfer rate: very slow.  Then I get the exact same NFS share that ESXi is used to store data directly in the comments and repeat the DD.  As you can see, the SD is longer and the synchronization takes no real time (as befits a NFS share with active sync), and the whole process takes less than 10 seconds: this is four times faster!

  I don't see these results on data warehouses mounted via NFS.  For example, here is a test on the guest even running from a mounted via iSCSI data store (using the exact same SIN):

  As you can see, the performance of NFS direct comments for each of the three are very consistent.  ISCSI and the performance of the store local data disk are both a bit better than that - as I expect.  But the mounted via NFS data store gets only a fraction of the perfomance of the any of them.  Obviously, something is wrong.

  I was able to reproduce this effect with an Iomega Ix4 - 200 d as well.  The difference is not as dramatic, butalways important and consistent.  Here is a test of a guest of CentOS using a VMDK stored in a data store provided by an Ix4 - 200 d via NFS:-.

  root@palladium /sync #; Sync; Sync; time {dd if = / dev/zero of = bs = 1 M count = test.txt 256 sync; sync; sync ;}}

  Once more, the direct NFS mount gives very consistent results.  But using the diskette provided by ESXi on a mounted NFS datastore gives still worse results.  They are not as terrible as OpenFiler test results, but they are constantly between 60% and 100% longer.

  Why is this?  What I've read, NFS performace is supposed to be within a few percent of the iSCSI performance, and yet I see between 60% and 400% worse performance.  And this isn't a case of the SIN is not able to provide correct NFS performance.  When I connect to the NAS via NFS directly inside the guest, I see much better than when ESXi connects to the same NAS (the same proportion!) via NFS.

  The configuration of ESXi (network and network cards) is 100% stock.  There is no VLAN in place, etc., and ESXi system has only one

  Single Gigabit adapter.  It is certainly not optimal, but it doesn't seem to me to be able to explain why a virtualized guest is able to get a lot better performance NFS as ESXi itself to the same NAS.  After all, they both use the same exact suboptimal network configuration...

  Thank you very much for your help.  I would be grateful any idea or advice, you might be able to give me.

  Hi all

  It is very definitely a performance O_Sync problem. It is well known that NFS VMware shops still use O_Sync for writes little matter what share put for a default value. VMware uses a custom file locking system so you really can't compare it to a normal NFS share connection to a different NFS client.

  I have validated that the performance will be good if you have an SSD cache or storage target with enough reliable battery backup.

• System backup Image against the system recovery disks

  Hello

  I'm new to the system recovery things and I have a question...

  I just bought a new computer laptop m7-1015dx of Pavilion and need to do system recovery discs... (which I realize restore laptop to factory default)... BTW, I have already created the system repair disc.

  However, I read an article on creating a system backup Image allowing you to recovery if lost EVERYTHING, all your installed programs, etc.

  First Question:

  Can someone tell me if I do the backup IMAGE of the system...

  Do I still need to create recovery disk (mfg default) system also?

  The second Question:

  If I create system recovery disks can I still this Recovery Partition?

  I am really really wanting to partition my C:\ drive... it is huge

  In addition, I hate to see storage folders involved in system folders...

  Currently using a symbol/character to separate them.

  From now on, I can't partition the C:\drive all partitions are used as... Max is 4

  and I have 4... C:\drive, System Partition, Partition HPTools and recovery Partition.

  Any help or assistance would be appreciated.

  Thanks for the research.

  Best regards, Jenn

  Hi, Jenn:

  I'd certainly recovery disks because in the case of a hard drive failure, a recovery partition is unnecessary because it would be on the failed drive.

  Recovery disks will do the same as a recovery partition. Reinstall the operating system and programs supplied with your laptop.

  I have also copy off the coast of the C:\drive SWSetup folder and store it on a portable hard drive that contains all files Installer provided with your PC (except MS Office 2010 Starter).

  You can also make your own Windows 7 installation disc and have a nice bloatware without installing windows, and then install only the programs you want from the SWSetup folder.

  Here's how:

  If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

  Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

  Or use the installation of Windows 7 USB/DVD tool to compile the ISO file that you download from Digital River. Link and instructions below. You need a 4 GB flash drive to use the USB compilation method.

  http://www.microsoftstore.com/store/msstore/HTML/pbPage.Help_Win7_usbdvd_dwnTool

  Use 25 characters on the PC product key to activate the installation.

  The key will activate a 32 or 64 bit installation.

  Then go to the support of the PC and driver page to install the drivers you need.

  Link to downloads ISO of W7 is below.

  http://www.mydigitallife.info/official-Windows-7-SP1-ISO-from-Digital-River/

  You can get rid of all the partitions you want to if you plan to use recovery or disc of Windows 7 installation method that I posted above.

  I write my product key and store them somewhere for more security that many people report that it fades if you keep the laptop on your lap a lot, and then you wouldn't be able to use the alternative method to install W7.

• backup of the old system changed the type of operating system installation

  After backup all data to your desktop at home and move the backup file on the replacement computer that was running and had been activated, got backup and ran into problems.  The original pc was an OEM system with a valid OEM key and had been activated for years.  The new system is a renewed system which has an apparently valid cd and COA 'For refurbished computers' active fine and had been restarted several times after activation before the fiasco of the backup.

  After that I ran the backup recovery, system was restarted as planned, but when the time came to connect to windows, we encountered a problem of activation.  He said that the system should be activated.  I went ahead and put in the key that is attached to the system (the key for PC) refurbished, but he would go through.  I checked that I read the key from the sticker correctly several times and by two other people.  He would not suffer.  Just on a chance that the backup of the old system caused a little problem, I tried the OEM key that was on the original system.  He's been through.

  If the old system should simply be scrapped, I don't think anything, but it will be either made to disadvantaged youth, so I want to make sure that everything is always good about it and it is all above board.  In its current form of the key is now on two different systems.  What can I do to fix this?

  Hi Ron68PB,

  1. you remember to make changes to the computer before this problem?

  2 are you able to open other programs?

  3. do you get error messages or error codes?

  Method 1:

  You try to run a SFC scan to check the corrupted system files.

  You can read the following article to launch the SFC scan:

  How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

  http://support.Microsoft.com/kb/929833

  Method 2:

  Alternatively, you can try to check if the problem occurs in safe mode.

• System could not find the environment option that was entered.

  The Trend Micro Client caused a bit of stir in my computer.

  He gave me the UiSeAgnt.exe error and I couldn't open any .exe files. I uninstalled Trend Micro and that pop up more rises. But the "System could not find the environment option/variable is entered" is yet to come when I try to run the .exe. This means that same cmd cannot be opened. I can not connect to the Internet independently wireless or wired. Audio system is not even the sense system speakers or external audio devices.

  I tried the system restore, did not work. I tried SFC/scannow, did not work. Now my current idea is to back up my files and blow the computer on with a clean restore. What should I do? I use a Vaio E series 14 p, btw.

  If it really comes down to it, how much memory should I backup everything?

  Hi Vey,

  Thanks for posting your query in the Microsoft community.

  Your system is connected to a domain network?

  This problem occurs in situations where Shutdown.exe cannot access the UserDomain environment variable. The task of the judgment which is on demand by using the at command runs under the system account. When the task is run under the System account, the UserDomain environment variable are not accessible because it does not exist. But the problem occurs mainly on the areas of server.

  I would suggest trying the following steps and check if these help to resolve the issue.

  1. start your system in safe mode.

  2. press on the Windows key + R.

  3. type sysdm.cpl , and then click OK.

  4. click on the "Advanced" tab

  5. in "Startup and recovery", click "Environment Variables".

  6. under "System Variables", click 'new '.

  7. for "Variable name", type in windir%

  8. for 'Value of the Variable', type in C:\Windows

  9. click OK on the all the dialog boxes that pop up.

  10. restart your system in normal mode.

  If, however, your system is connected to the normal mode, please see the following support article.

  Zitouni,

  Thanks for your reply, good point on the File Checker, I didn't know that. Unforuneatly I have not see your reply until I decided it was time to re - install the system. One thing to note, I couldn't do a 'run as administrator' anyway possible. This system was really corrupt which leads me to believe that he may have been a NTFS/Fat 32 Co-mingling question. Just a guess, but I really don't see how it could have happened otherwise.

  Another thing to note, if you have a Dell Inspiron 1720 with a 250Gig HD-make sure that you format the partition, you then load the SATA drivers! Also, make sure that the restore partition does not primary. Make sure that you format (assuming that you have backed up your data before!). Otherwise, it hangs on Setup to complete the installation. Who took me ahwhile to understand.

  Everything is cool now (reinstalled Vista), just thank ful there is a site like this to run things by! ;)
