Described herein is a system method for point in time blob restore. In response to receipt of a request to restore a particular blob range to a particular point in time, read and/or write operations on the particular blob range requested to be restored are blocked. Blob(s) in the particular blob range which have changed since the particular point in time are determined based, at least in part, upon information stored in a change log and/or a deleted blob store. A determination is made as to whether the requested restore operation can be performed, for example, based upon a restoration policy. When it is determined that the requested restore operation can be performed, blob(s) determined to have changed since the particular point in time based, at least in part, upon information stored in the change log and/or the deleted blob store are restored.

Point in time blob restore

A cloud storage system includes a processor and a non-transitory computer-readable medium to store blob table management instructions for execution by the processor. The blob table management instructions are configured to manage a plurality of storage requests for a blob stored in a storage stamp as snapshots in a blob table and selectively create a user snapshot of at least one of the snapshots in the blob table. When automatic snapshots are enabled, the blob table management instructions are configured to receive a first request to overwrite the blob. If the first request does not further specify a key of the one of the snapshots in the blob table, the blob table management instructions are configured to add a new snapshot to the blob table and maintain storage of a prior snapshot of the blob for a maximum period.

Distributed data storage system with automatic snapshots, user snapshots and soft delete

Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, Bluetooth, UWB or any other suitable wireless technology. A graphical user interface is provided that enables a user to select a desired service.

Notification framework for wireless networks

A wireless access point in a wireless network that may be adapted to transmit location data indicating its location to other devices. In some embodiments, the location data may be embedded in a control message or other message used to broadcast information necessary for a device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions.

Transmitting location data in wireless networks

A wireless access point in a wireless network that may be adapted to transmit location data indicating its location to other devices within range, including other wireless access points and client devices. The location data may be embedded in a control message or announcement transmission transmitted by the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device. Devices receiving the location data may use the received location data to determine their own locations, and may provide the determined locations to consumers of location data.

In some embodiments of the invention, the location data may be embedded in a control message or announcement transmission transmitted by the wireless access point, or other message conventionally used to broadcast network characteristics necessary for a client device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device.
