Abstract
Provided are mechanisms and processes for a improving the processing and network efficiency of cloud backup bulk data export operations. Data being restored from cloud backups and archives to multiple devices can be intelligently analyzed in order to reduce consumption of network and processing resources on wide area networks and at cloud backup service providers. Data analysis may involve generating blockmaps, analyzing metadata, and determining other data attributes in order to reduce redundancy, determine tasks that can be handled locally, and benefit from other data characteristics.
Claims20
A method, comprising:
- receiving at a server a request to bulk export data to a plurality of users including a first user and a second user, the bulk export data comprising a plurality of files to be restored onto a first user device associated with the first user and a second user device associated with the second user, wherein the server is connected to the first and second user devices over a wide area network and the first and second user devices are connected to each other over a local area network;
- traversing a first plurality of files to be restored for a first user;
- restoring the first plurality of files to the first user by transmitting the first plurality of files over the wide area network;
- identifying a first subset of files and a second subset of files in the first plurality of files, the first subset of files common to the first and the second user and a second subset of files not common to the first and the second user;
- restoring the first subset of files at a file level to the second user by copying the first subset of files from the first user to the second user over a local area network;
- restoring the second subset of files at a block level to the second user by determining common elements of the second subset of files to be restored for the second user, wherein common elements are determined by referencing a plurality of blockmaps associated with the first plurality of files and the second plurality of files, wherein common elements are further determined by traversing a reverse map that, for each block handle, identifies a user identifier, a filepath, and an offset within the filepath that references the block;
- restoring the common elements of the second subset of files the second user by transmitting the common elements over a local area network from the first user device to the second user device;
- and
- restoring a second plurality of files to a second user by transmitting the second plurality of files minus the common elements over a wide area network to the second user.

A non-transitory computer readable medium, comprising:
- computer code for receiving at a server a request to bulk export data to a plurality of users including a first user and a second user, the bulk export data comprising a plurality of files to be restored onto a first user device associated with the first user and a second user device associated with the second user, wherein the server is connected to the first and second user devices over a wide area network and the first and second user devices are connected to each other over a local area network;
- computer code for traversing a first plurality of files to be restored for a first user;
- computer code for restoring the first plurality of files to the first user by transmitting the first plurality of files over the wide area network;
- computer code for identifying a first subset of files and a second subset of files in the first plurality of files, the first subset of files common to the first and the second user and a second subset of files not common to the first and the second user;
- computer code for restoring the first subset of files at a file level to the second user by copying the first subset of files from the first user to the second user over a local area network;
- computer code for restoring the second subset of files at a block level to the second user by determining common elements of the second subset of files to be restored for the second user, wherein common elements are determined by referencing a plurality of blockmaps associated with the first plurality of files and the second plurality of files, wherein common elements are further determined by traversing a reverse map that, for each block handle, identifies a user identifier, a filepath, and an offset within the filepath that references the block;
- computer code for restoring the common elements of the second subset of files to the second user by transmitting the common elements over a local area network from the first user device to the second user device;
- and
- computer code for restoring a second plurality of files to a second user by transmitting the second plurality of files minus the common elements over a wide area network to the second user.
