  • Backup tools free trial limitations

    - by Raphael Royer-Rivard
    I would like to use a backup tool like Acronis or Crashplan in case I encounter a serious problem with my computer and I want to restore it like it is right now. They both have a free trial of 30 days but they do not seem to explain explicitly what won't be functional after the trial period. Is the restore feature still available after the trial period or must my computer die within the 30 days for this trial to be useful?

  • recommendations for efficient offsite remote backup solution of vm's

    - by senorsmile
    I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

  • Can "tar" backup incrementally?

    - by Somebody still uses you MS-DOS
    I have my home folder with a few GB. Is it possible to run tar on it, create a home.tar.gz, and then for changed files, it creates home1.tar.gz only with modified files from previous tar (thus being an incremental backup)? I would like to check the resulting checksum files and export them as well like home.md5, home1.md5, etc. (I know this could be another process, but interesting as well).

  • Have a server, need to figure out a method of backup

    - by PolishHurricane
    My company has an older Dell 2650 server running ArchLinux x64: http://www.dell.com/downloads/global/products/pedge/en/2650_specs.pdf (2 x 2.4GHz Intel Xeon w/around 3287 RAM according to "free -m") We use it to host our internal company site and to post some information from our orders to and we'd like the ability to keep it up as much as possible. What we require: - It needs to always be functional from 8am to 4pm for our data entry person to use it and others to do other things required on it. - If it goes down, we need a quick way to get the machine running again. - If it goes down, we would like to have the data backed up. Some of the major problems include: - The servers old and it may have memory issues - We don't know when one of the hard drives could fail - Our power goes out here once in a while We have a battery backup, but that's pretty much it and it's not for long term. If the server does go down, we have another system in place to store order information that comes in while it's down and repost it when it's back, but we need it up during the day. So we're wondering, what should we get for options? These are the things we thought of, sort of: Setup RAID 1, but that would involve wiping everything right? If we do that, how would we transfer the data over without messing up the server? We could buy an extra server or 2 off eBay for $100, the same model, is that practical or should we get something else? Should we buy a PC or another better server and host off that because it is if anything easier to exchange parts? Should we keep extra parts handy incase it implodes? Should we buy/use backup software? We hear drobo's are cool, but suck. Perhaps there is a software solution to this problem that backs up to another machine or gets us up and running again quickly. Also, if we are to purchase hardware, what is decent? Does anybody know of one for ArchLinux/Linux? We both know a ton about computers but we're kind of unsure what step to take with this, especially with this type of server. Thanks

  • Software for Automatic Remote FTP Backup

    - by Baez
    I'm looking for software (free or paid) that could perform a weekly automatic backup to an outside server via FTP. I've looked around and all I seem to be finding is either garbage shareware or free tools that are no longer supported. The system will be backing up from a Windows 7 desktop system to a Linux CentOS 5 server. Can someone direct me to a stable, reliable piece of software? This is for business documents so reliability is key.

  • .net web service: Can't add service reference, only web reference

    - by ScottE
    I have an existing project that consumes web services. One was added as a service reference, and the other as a web reference. I don't recall why one was added as a web reference, but perhaps it's because I couldn't get it to work! The existing service reference for the one web service works fine, so it's not a .net version issue. I can successfully create a service reference for the second web service, but none of the methods are available. The .wsdl shows the schema, but the Reference.vb shows only the Namespace, and none of the methods. To clarify, these are two different 3rd party web service providers. We'd like to move to the service reference so we have more control over the configuration as we're having various issues with timeouts. Anyone come across this before? Edit Does it matter that there are two services at the address?

  • How to learn high-level Java web development concepts

    - by titaniumdecoy
    I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

  • Efficiently making web pages from multiple servers

    - by james.bcn
    I want to create a service that allows diverse web site owners to integrate material from my web servers into content served from their own servers. Ideally the resulting web page would only be delivered from the web site owners server, and the included content would be viewed as being part of the site by Google - which I think would rule out iframes or client-side Javascript to get the content from my server (although I may be wrong about that?). Also the data wouldn't actually be updated that often, say once a day, so it would be inefficient to get the data from my web servers with every request. Finally, the method needs to be as simple as possible so that it is easy for web site owners to integrate into their own sites. Are there any good methods for doing this sort of thing? If not then I guess the simple way is with iframes or Javascript.

  • How to restrict access to my web service?

    - by Hank
    I have http://example.com/index.html, which from within the HTML uses JavaScript to call a web services at http://example.com/json/?a=...&b=... The web service returns to index.html a JSON array of information to then be displayed on index.html. Since anyone can view the source code for index.html and see how I'm calling the JSON web services (http://example.com/json/), how do I prevent people from calling my JSON web service directly? Since the web service is essentially an open read into my database, I don't want people to abuse the web service and start DoS my server, fetching more information than they should, etc..

  • How popular is C++ for making websites/web applications?

    - by Vilx-
    I don't know why this is question is bugging me, but time after time I come back to the though - why not make websites in C++? So far I know of none (except a rumor about Yahoo). Most use PHP, Java or ASP.NET. Some are built on Ruby or Python, but even those are minorities. At the same time, looking at StackOverflow, it seems that C++ is still a very popular language with many projects written in it. Why not for webpages? So - what do you know about this subject? Are there any websites written in C++? Are there any framewroks/libraries that help doing this? Have YOU ever done it? If yes, did you run into any fundamental problems and would you recommend this to others?

  • Backup Your Windows Home Server Off-Site with Asus Webstorage

    - by Mysticgeek
    Windows Home Server lets you backup machines on your network easily. But what about backing up the server data? Today we take a look at ASUS WebStorage for Windows Home Server, which provides you with secure off-site backup for WHS. To use the ASUS WebStorage service you’ll need to sign up for a free account. It offers 1GB of free storage, then you can purchase an unlimited backup package for $39.99 for a year subscription. Note: They also offer online storage for individual PCs as well. Install ASUS WebStorage for WHS Browse to your shared folders on the server and open the Add-Ins folder and copy over the WHSConnectorSetup2.2.4.088.msi file (link below) then close out of the folder. Now launch Windows Home Server Console from one of the computers on your network, click Settings, then Add-ins. Under Available Add-ins click the Available tab and you’ll see the Asus WebStorage installer file we just copied over. Click the Install button. Installation kicks off and when it’s complete, you’ll need to close out of the console and reconnect. Using ASUS WebStorage WHS Connector  When you reconnect to WHS Console, scroll over to the ASUS WebStorage icon and click on Settings. Now log into your ASUS account… Now select the folders you want to backup to the WebStorage service. Select the radio button next to Enable to initialize the backup process… The backup process begins. You can change which folders are backed up simply by disabling the backup process, uncheck the folder(s), then enable the backup again. ASUS WebStorage Site After you have files backed up to the ASUS site, log into your account, and your presented with an overview of the amount of storage you’re using. It also shows what type of files are taking certain amounts of space.   You can browse through your backed up files and folders. It allows you to share and sync backed up data as well. Navigate to the file you want and you can easily download it by clicking on it, or share it out by clicking the share link below it. If you choose to share it, you’re provided with a link to the file to send out to other users.   Conclusion Users of Windows Home Server have been looking for an inexpensive cloud backup solution for quite some time. There are services such as JungleDisk, KeepVault, Wuala…etc. These services probably do a better job, but can start getting expensive once you start uploading a GBs of data. Another disappointment of ASUS WebStorage is you can only backup your WHS shares (from what we’ve been able to determine), it’s an “all or nothing” type of thing. You cannot go in and select individual files and folders. The initial upload speeds can be a bit slow as well, although that might have something to do with limited upload speeds on the DSL connection we used to test it. Retrieving your data from the ASUS site is a breeze though, and all the data files are organized quite well. The WHS Addin is very easy to install and use. If you’re looking for an off-site solution to backup your WHS data, you can test out ASUS WebStorage for free with a 1GB limit. This is good for testing the service and it might be exactly what you’re looking for. Other users may want a more advanced solution like KeepVault or CloudBerry…which is a front end for Amazon S3 storage.

  • Windows Server 2008 backup VHD's - is it possible to mount/open in Windows 7?

    - by Simon
    Hi All, Is it possible to mount the VHD files created by the Windows Server 2008 backup utility onto a Windows 7 (release) client? Following an array failure I was very worried that there was a problem with both the backup sets on different USB drives as attaching the VHD to a Win 7 box did not show the expected structure (instead they behaved like unformatted disk space). Subsequently, I've attached the backup drive to a 2008r2 machine that I'd intended to be the replacement and the backup set can be browsed without issue (seemingly). When the new disks arrive I'll go through the recovery process and see where we are, but it looks promising so far. Is it simply the case that you can't take server created VHD's and mount them on desktop machines? (Rather than hyper-ventilating at the thought of years of lost photos and email, I'm now just mildly curious) Edit:One thing that has confused things is that the backup utility on Win7 is more restrictive about restoring from external devices than the equivilent on 2008r2. With r2, I can restore files 'from another server' and browse to external storage. Win7 only allows the back to be located on a network share. Once my box of new disks arrive and I've got something to restore onto, I'll move the smaller of the backup VHDs onto network storage reachable by Win7 and see if the VHD is readable. I haven't read up on the VHD process used by the backup app - I'm assuming it's a base VHD and differencing files used for incremental backups and that the restore app understands this. Finally: In retrospect the question should have been, 'can I restore a 2008r2 backup set via a Win 7 client' Thanks

  • Why am I not able to create a backup plan for TFS?

  • Are ZFS snapshots + S3 a viable backup system for several VMs and general fileserver storage?

    - by AllanA
    I've been tasked with setting up a backup system for my small office (around 12 people). Most of our production stuff is on the AWS cloud, so what I need to back up are some small office/development files (under 100G right now), plus our operational VMs and development, which round out to a bit under 1T. I just need something reliable, convenient, and straightforward. I'm comfortable with Linux, FreeBSD, and to some extent Solaris 10, so I'm leaning toward a full server rather than an appliance system ala Openfiler or FreeNAS. What I'm contemplating is a small fileserver for general storage and nightly backups of the virtual machines, followed up by an offsite backup to Amazon's S3 storage service. It'd be the usual incremental backups nightly and full backup weekly. My question is if using ZFS snapshots, both locally and dumped to S3 via 'zfs send [-i]', is a viable backup tool? Or should I stick to using Duplicity, or some other method entirely? ZFS snapshots on the internal fileserver/backup machine sound like a perfect way to provide quick and convenient data recovery, so I'm likely to go with that for local redundancy. (If you folks see scenarios where relying on ZFS snapshots would be worse than a more traditional archiving backup, feel free to convince me.) But are snapshots flexible enough to lean on for recovery from the loss of my backup server? Or am I better off with something more traditional? (feel free to recommend free or commercial backup solutions you favor.)

  • Creating a bare bone web-browser: After the html parser, javascript parser, etc have done their work, how do I display the content of the webpage?

    - by aste123
    This is a personal project to learn computer programming. I took a look at this: https://www.udacity.com/course/viewer#!/c-cs262 The following is the approach taken in it: Abstract Syntax Tree is created. But javascript is still not completely broken down in order not to confuse with the html tags. Then the javascript interpreter is called on it. Javascript interpreter stores the text from the write() and document.write() to be used later. Then a graphics library in Python is called which will convert everything to a pdf file and then we convert it into png or jpeg and then display it. My Question: I want to display the actual text in a window (which I will design later) like firefox or chrome does instead of image files so that the data can be selected, copied, etc by the user of the browser. How do I accomplish this? In other words, what are the other elements of a bare bone web browser that I am missing? I would prefer to implement most of the stuff in C++ although if things seem too complicated I might go with Python to save time and create a prototype and later creating another bare bone browser in C++ and add more features. This is a project to learn more. I do realize we already have lots of reliable browsers like firefox, etc. The way I feel it is done: I think after all the broken down contents have been created by the parsers and interpreters, I will need to access them individually from within the window's code (like qt) and then decide upon a good way to display them. I am not sure if it is the way this should be done. Additions after useful comment by Kilian Foth: I found this page: http://friendlybit.com/css/rendering-a-web-page-step-by-step/ 14. A DOM tree is built out of the broken HTML 15. New requests are made to the server for each new resource that is found in the HTML source (typically images, style sheets, and JavaScript files). Go back to step 3 and repeat for each resource. 16. Stylesheets are parsed, and the rendering information in each gets attached to the matching node in the DOM tree 17. Javascript is parsed and executed, and DOM nodes are moved and style information is updated accordingly 18. The browser renders the page on the screen according to the DOM tree and the style information for each node 19. You see the page on the screen I need help with step 18. How do I do that? How much work do Webkit and Gecko do? I want to use a readymade layout renderer for step number 18 and not for anything that comes before that.
