  • two questions about the scattered images secure

    I created an image that is secure and encrypted for sensitive documents.

    I have two questions:

    1. when I use the disk (if it is up, open and available), and I want to add something to it, I usually drag the file everywhere where it is currently in its destination folder in the sparse image control.  But it automatically makes a copy - with the same name (not with a '-1' ever, not with a suffix 'copying' or 'alias').  Which defeats the purpose and makes things complicated - I find myself comparing what is in each location to make sure it's in the sparse image and then it makes me nervous to delete the original.  Why it does this and how can I change such as dragging a file in a secure location gives there is not that a second copy of it left in an UNsecure location?

    2. I'm using Time Machine backup drive sitting on my desk (and a separate utility for monthly clones on a different backup disk).  Automatically makes Time Machine backup the content of the rare picture even if the safe drive is not mounted, open and available?  I hope not, because that would undermine the usefulness of having a backup disk on my desktop running of ordinary Time Machine backups, but find it me just that all the steps I take of course I do not lose any data may be so overprotective I have thought/hoped.

    Sous_forme_d' addendum, I'll check my clone, but as I put this out there, I wonder if SuperDuper!, my application of cloning is cloning automatically secure disk content, so... like the thoughts of anyone about it if it's an application that they use).

    FYI: I'm running 10.11.2

    Thank you.

    (1) by default, OS X makes a copy with the overcoming of the limits of volume and moves when in the same volume.

    You can reverse this behavior by holding down the command key when you drop. You will see the insignia of the icon changes (green + for copy, empty for move).

    (2) Time Machine will return to the top of the image 'file', but only when it is unmounted. I do not think that it automatically includes the volume mounted, but I would like to check and add to the exclusion list.

  • Exam question-value of the point and unanswered questions about the VCP4 exam?

    Hello

    I have a few questions about the scoring to secure Channel 4 review system:

    1. All the questions on the exam are weighted the same?

    2. Is there a penalty for unanswered questions?  In other words, is it better to not answer a question, if you are sure that you do not know the answer, or take a guess if it comes down to it?

    Thank you very much

    Bryan

    Not responding not to an element, it is the same thing that answer wrongly as far as scoring is concerned, so it makes sense to guess rather than leave the question unanswered.

    With respect to the weighting, all elements have the same weight in the VCP exam, but some items do not count against the overall score.  These "dosed" items continually change and are chosen at random.  We insert elements assayed to determine the validity of the element until it became a party has received from the real exam.  If however, you want to treat each item with an equal amount of importance.

    Hope this helps,

  • Questions about the firewall Console of service

    1. in some documents for ESX 4 it is worth noting that the firewall uses the default settings, which should mean that incoming and outgoing sessions must be explicit 'high security' allowed. This is perfect, but I wonder: I do not see anywhere that I can put a few "medium security" level or similar, so my question is if it was something that could be done in older versions of ESX and the names have been deleted?

    2. is it true that the firewall settings that I see in the vSphere Client is not really all parameters? I don't see any reference to tcp/443 for example and I don't think that ports 902/903 are there either. What about ICMP? Is that so many rules that could cause big problems if disabled incorrect is hidden for the user?

    3. in ESX 4 firewall seems to be quite autoconfiguration, as in if I activate the client iSCSI, that the rules are changed automatically. New behavior in 4.0, it was is different in earlier versions?

    Fix. There are default ports that are open by default with high security. See Firewall Service Console Configuration

    I can't tell you how it was in earlier versions. Those that I know that the necessary configurations are completed automatically. Only applications 3 - rd party (such as HP management agents) had to configure their settings individually.

  • Questions about the implementation of clusters of storage and DTS on active cluster

    I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

    We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

    Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

    Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

    What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

    I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

    If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

    I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

    Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

    Thanks in advance for your comments.

    Hello

    Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

    Gregg

    With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

    Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

    In short: don't go there.

  • Question about the OSB proxy service

    Hello

    I'm new to the world of SOA/OSB. I'm working on a POC from the OSB for our existing application. I have a question about the definition of the URL endpoint to the proxy service. It is possible to specify a generic url endpoint to a proxy service. Something like / SomeService / *. I tried and got errors. Is it possible to do somethig like that or it is a mistake on a conceptual level.

    Thank you

    anything you type in the uri of the endpoint of entry will be the contextroot to your service, so /SomeService should indeed be sufficient or as mentioned Pierluigi/SomeService/blabla is also valid (Betty is not a parameter query, but only a part of the contextroot)

    If you want to use a service like http rest

    / SomeService/blabla would still be the contextroot, and after that, you can use the query parameters

    / SomeService/badarou? var1 = test & var2 = test or/SomeService/blabla/employee/id/1

  • A few questions about the difference between the Satellite P70, L70, S70

    Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

    (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

    (3) all the three (P70, L70, S70 series) come with the same TFT panels?

    (4) of the above series, which supports mSata?

    (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

    (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

    (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

    Thank you in advance.

    > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

    (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
    As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

    I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

    (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
    See point 1). Different P70, L70, S70 models were equipped with different material parts.

    (> 4) of the series above, which takes in charge mSata?
    As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

    (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
    See point 4) not all models supports the same hardware specifications

    (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
    I don t think that SATA III is supported. I guess it would be SATA II

    (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
    Not easy to answer because there are too many models released in Europea.
    And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.

  • A few questions about the upgrade on Satellite A300-144

    Sorry for the typos, English is not my mother tongue.
    I want to ask some questions about the upgrade of a300-144.

    * Some info first.*

    CPU: T2370 ([http://ark.intel.com/products/34445/Intel-Pentium-Processor-T2370-1M-Cache-1_73-GHz-533-MHz-FSB]).
    Chipset: GM965 ([http://ark.intel.com/products/29821/Intel-82GM965-Graphics-and-Memory-Controller]).

    * Questions.*

    1. my frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    2 Intel said that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?

    3 I know, taken of my CPU is μFCPGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 ([http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB]) is a compatible processor or there are some limitations in the BIOS?

    > 1. My frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    The speed of the memory is related on the material. This means that the FSB is responsible for the limitation.
    If the FSB would allow support 667 MHz then the memory would also at this speed.

    > 2. Intel says that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?
    The memory depends on the chipset. So if the chipset supports 4 GB of RAM, you should be capable of this move to 4 GB of RAM

    > 3. I know, my CPU is? FC-PGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 (http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB) will be a compatible processor or there are some limitations in the BIOS?

    It might be possible that the new processor would be fully supported by the BIOS, but in most cases it should not be a problem if the chipset would support the new processor.
    But as far as I know the upgrade of the CPU is not supported by Toshiba or any other manufacturers of portable and its your own risk to run laptop with the new processor.

  • Question about the recovery partition

    Hello.

    I have a question about the recovery of HARD drive partition.

    If I do the operation to clear the hard disk option in the wizard it will remove * all * or it will keep my partition recovery in this way I can come back later. I want to know because I would like to put on a different OS.

    I know he said he would, but caution in the PDF, I found it says that on a normal recovery too (that he would remove each partition) and I'm a little confused about how the recovery actually worked.

    Thank you.

    Hey Buddy,

    To be honest I n don't know what you mean exactly with this option to erase.

    In General, Toshiba Recovery disk will wipe your entire HDD to restore factory settings correctly. This means that if you start from that disk and follow the instructions on the screen, everything will be removed.

    In addition, the recovery disk doesn t create a recovery partition. It is not available. Disk copy just the files on the second partition in folder HDDrecovery to start an installation of HARD drive recovery.

  • A few questions about the Satellite A100 PSAANE

    Hi friends,

    I have a Toshiba Satellite A 100 - PSAANE with Vista Home Basic preinstalled in it.
    Now, I have a few questions... I mention below: -.

    (1) if I want to format my laptop, I need a CD to install for Vista Home basic... then I don't have this Toshiba CD when I bought the laptop. So how do? question: How can I format it?

    (2) can I change my Vista Home Basic to windows XP? I think it's much faster than this one. is it advisable?

    (3) I have a GB of RAM in the laptop. Increase the RAM? I think that my laptop has become to slow down. is it advisable?

    (4) and on my screen, everytime I try to change my profile screen to windows Classic view, my screen begins to blink. and after a while, the screen turns off. So I can't change that. I put the color scheme of windows vista only. What to do about that?

    Please help me friends. Thanks in advance.

    Kind regards

    Hello

    Here, a few questions about the number:

    (1) usually, you should get the Vista Toshiba Recovery DVD. If you didn t receive this DVD then you can order it here https://backupmedia.toshiba.eu/landing.aspx or you could install the disc of Microsoft Vista.

    (2) of course, you can do this. I think that Win XP drivers can be downloaded from the Toshiba driver page.

    (3) Yes, you can upgrade the RAM. For more information, see your manual or search on this forum for similar topics

    (4) maybe it s associated with the graphics driver. Check if you can update. I would recommend additional check if you are using the latest version of the BIOS

  • Re: Several questions about the recovery of the Satellite L750 features

    I have several questions about the recovery of Satellite L750 features available to it. Any help and answers would be useful.

    (1) when I started the laptop first, he asked me to create a recovery CD incase I need to reinstall the operating system. But he also said that he built in the recovery partition, so therefore, I have to make a recovery cd or not?

    (2) will be the recovery CD is exactly the same as the recovery on the system partition?

    (3) is the partion of CD or recovery includes all the integrated software pre-installed with the laptop?

    (4) also in the device manage management it shows watch partion recovery but it is empty, is it true?

    (5) in the second partition (drive D) system, he has a record with what looks like the recovery of files and folders. Is it safe to move/remove it?

    Hello

    I'll try to provide answers:
    1 - to ensure that everything works perfectly you don t need these discs, but if something goes wrong with the HARD drive you will not be able to do anything. When you have the recovery DVDs, you will still be able to install the recovery image and once again the factory settings. So my advice to you is: create these discs as soon as possible. Use only on DVD-R media and buy products of high quality (TDK or Verbatim).
    2 - Yes.
    3 - Yes.
    4 - No. Don t be confused with this.
    5. in a first time create restore DVD, and later you can do what you want. I put t know which files mean you but don t touch anything before that of the recovery disks to be created.

    In the past, many people have been experimenting with the structure of HARD drive and partitions and later was surprised when installing disk recovery HARD has been damaged. Don t make the same mistake.

    If you have any other questions you are welcome.

  • Question about the new Yoga 10 HD +.

    Hello

    A few questions about the new Yoga 10 HD + that I hope you can answer.

    I bought the former model, last year. Love the design and long battery life, but a few major questions made me return.

    • Somewhere that I've read that it can not read NTFS on USB so I guess that's the same thing with a NTFS formatted microSD card?
    • Can it read exFAT formatted microSD cards?
    • Anyone who has questions about the audio via bluetooth?
      (I know that BT is not exactly High End HiFi but the old 10 Yoga for some obscure reason - most likely a driver problem which nobody cared to fix - rang * very * worst with visibly distortion while both my phone and a Tablet noname cheap I have zero about fidelity - any of my devices bluetooth audio) I tried aptX or not)

    So to avoid buying it back it also I really I would like to see if I can get my questions answered before buy you.

    While I love the form factor and long term issues above are only two Mayor dealbreakers for me. Bad audio quality = no joy listen to spotify, local etc. MP3s. not of NTFS or exFAT = some great movies.

    My old noname android Tablet really could use an upgrade so I'm really curious it may be, or I should watch the competition and will be form factor and battery LIFE.

    Thanks in advance.

    EDIT:

    If it does not support NTFS or exFAT on microSD card have someone at - he tried ext3 or ext4?

    I mean with Linux Android root, it should be a no-brainer to support at least when it comes to royalties unlike NTFS or exFAT where it * might * have some trouble with Microsoft.

    I used a USB through a USB OTG cable. NTFS or exFAT have been recognized by the Tablet PC. FAT32 is seems to be the preference.
