DISTRIBUTED CLOUD STORAGE
Distributed cloud-based data storage divides a file for storage into a number of portions that are separately stored with two or more storage service providers. The division and/or transmission of the file may be implemented based on arbitrary criteria, including random selection, an applied storage policy or assignment of a given portion to a corresponding storage service provider as examples. One or more portions of the file may be assembled into an upload file that is transmitted to and received from a storage provider. The portions of the file received from the storage provider may be used to reconstruct the file.
1 . A method for storing distributed data, comprising:
dividing a set of data into at least a first portion and at least a second portion;
transmitting the at least first portion to a first storage service provider; and
transmitting the at least second portion to a second storage service provider.
2 . The method according to claim 1 , further comprising dividing the set of data in accordance with a criteria.
3 . The method according to claim 2 , wherein the criteria is one or more of a format, a sequence or an algorithm.
4 . The method according to claim 2 , wherein the criteria is random selection.
5 . The method according to claim 2 , wherein the criteria is based on assignment to the first storage service provider or to the second storage service provider.
6 . The method according to claim 2 , wherein the criteria is based on a sequence of service providers that includes the first storage service provider and the second storage service provider.
7 . The method according to claim 6 , wherein the sequence of service providers is randomly selected.
8 . The method according to claim 1 , further comprising:
arranging the at least first portion in a first file;
arranging the at least second portion in a second file;
transmitting the first file to the first storage service provider; and
transmitting the second file to the second storage service provider.
9 . The method according to claim 1 , further comprising forming a key file that indicates how the set of data is divided into the at least first portion and the at least second portion.
10 . A method for retrieving distributed data, comprising:
receiving a first file from a first storage service provider;
receiving a second file from a second storage service provider;
extracting a first portion of a data set from the first file;
extracting a second portion of the data set from the second file; and
reconstructing the data set using the first portion and the second portion.
11 . The method according to claim 10 , further comprising reconstructing the data set in accordance with a criteria.
12 . The method according to claim 11 , wherein the criteria is one or more of a format, a sequence or an algorithm.
13 . The method according to claim 11 , further comprising obtaining the criteria from a key file that indicates how the data set is to be reconstructed.
14 . A non-transitory machine-readable storage medium comprising machine-readable instructions configured to be executed by a machine to cause the machine to:
divide a set of data into at least a first portion and at least a second portion;
transmit the at least first portion to a first storage service provider;
transmit the at least second portion to a second storage service provider;
receive the at least first portion from the first storage service provider;
receive the at least second portion from the second storage service provider; and
reconstruct the set of data using the first portion and the second portion.
15 . The medium according to claim 14 , further comprising instructions to divide or reconstruct the set of data in accordance with a criteria.
16 . The medium according to claim 15 , wherein the criteria is one or more of a format, a sequence or an algorithm.
17 . The method according to claim 15 , wherein the criteria is based on assignment to the first storage service provider or to the second storage service provider.
18 . The method according to claim 15 , wherein the criteria is based on a sequence of service providers that includes the first storage service provider and the second storage service provider.
19 . The method according to claim 15 , further comprising instructions to form a key file that indicates how the set of data is divided into the at least first portion and the at least second portion.
20 . A method for implementing a storage policy in a distributed storage arrangement, comprising:
configuring parameters of the storage policy for storage of a file;
receiving an indicia to apply the storage policy to the file;
dividing the file into at least a first portion and at least a second portion in accordance with the storage policy; and
transmitting the at least first portion or the at least second portion to a storage service provider in accordance with the storage policy.
