  • Patent number: 8868513
    Abstract: A disaster recovery system, including a target datastore for replicating data written to source datastores, and a checkpoint engine (i) for transmitting, at multiple times, quiesce commands to a plurality of host computers, each quiesce command including a timeout period that is adjusted at each of the multiple times, (ii) for determining, at each of the multiple times, whether acknowledgements indicating that a host has successfully stopped writing enterprise data to the source datastores, have been received from each of the host computers within the timeout period, (iii) for marking, at each of the multiple times, a cross-host checkpoint in the target datastore and reducing the timeout period for the quiesce commands at the next time, if the determining is affirmative, and (iv) for increasing, at each of the multiple times, the timeout period for the quiesce commands transmitted at the next time, if the determining is not affirmative.

  • Publication number: 20120151273
    Abstract: An enterprise disaster recovery system, including a processor for running at least one data application that reads data from at least one data disk and writes data to the at least one data disk over a period of time, a recovery test engine that (i) generates in parallel a plurality of processing stacks corresponding to a respective plurality of previous points in time, each stack operative to process a command to read data at a designated address from a designated data disk and return data at the designated address in an image of the designated data disk at the previous point in time corresponding to the stack, and (ii) that generates in parallel a plurality of logs of commands issued by the at least one data application to write data into designated addresses of designated data disks, each log corresponding to a respective previous point in time.

  • Publication number: 20120137173
    Abstract: A system for disaster recovery including a controller (i) for controlling bandwidth usage of a disaster recovery system in accordance with a plurality of recovery point objectives (RPOs), each RPO designating a maximal time loss constraint for data recovery for an enterprise production system, and a corresponding bandwidth allocation for the disaster recovery system to use in replicating data for the enterprise production system, wherein the RPOs are applied in accordance with a calendar-based schedule of dates and times, and (ii) for issuing an RPO alert when the RPO maximal time loss constraint for a current date and time is not satisfied.

  • Publication number: 20060236378
    Abstract: A method for connecting a user computer to a first computer network includes transmitting a connection request by the user computer, via a second computer network, requesting a connection to the first computer network. The second computer network is automatically solicited to authorize the user computer, responsively to a failure of the connection request. Upon authorization by the second computer network, a connection is established between the user computer and the first computer network via the second computer network.

  • Publication number: 20060069782
    Abstract: A method is disclosed for determining whether access to a host requested by a client session connection is permitted. After determining attributes of the client session connection, a list of hosts is selected based on the determined attributes of the client session connection. The list of hosts is then used to determine whether access to the requested host is permitted. The disclosed method can be used to allow for location-specific white lists of free URLs for a user at a wireless network hotspot that the user can access before being authenticated.

  • Publication number: 20060056317
    Abstract: A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.

  • Publication number: 20060059092
    Abstract: A method is disclosed for determining a whether access to host requested by a user is permitted. User identifying information is obtained using any of a variety of techniques. The method includes determining a user domain, which indicates an identity of the user's home service provider. A list of hosts is determined based on the home provider. If the requested host is in the list of hosts, then the user is allowed access to the requested host though the user is not authorized. The list of hosts may be determined by one or more attributes from an actual or implied user profile, such as a domain name.
