Abstract

Data storage operations, including content-indexing, containerized deduplication, and policy-driven storage, are performed within a cloud environment. The systems support a variety of clients and cloud storage sites that may connect to the system in a cloud environment that requires data transfer over wide area networks, such as the Internet, which may have appreciable latency and/or packet loss, using various network protocols, including HTTP and FTP. Methods are disclosed for content indexing data stored within a cloud environment to facilitate later searching, including collaborative searching. Methods are also disclosed for performing containerized deduplication to reduce the strain on a system namespace, effectuate cost savings, etc. Methods are disclosed for identifying suitable storage locations, including suitable cloud storage sites, for data files subject to a storage policy. Further, systems and methods for providing a cloud gateway and a scalable data object store within a cloud environment are disclosed, along with other features.

Claims15

Dependent claims

A non-transitory computer-readable medium storing instructions that when executed by at least one processor perform a method for encrypting files stored within a cloud storage site, the method comprising:

receiving a request to encrypt a data file located on a cloud storage site;
receiving an indication of a requested type of encryption method to utilize when encrypting the data file located on the cloud storage site,
wherein the requested type of encryption method is one of multiple types of encryption methods;
and
determining whether the requested type of encryption method is supported by one or more application programming interfaces (APIs) provided by the cloud storage site;
when the requested type of encryption method is supported by the one or more APIs provided by the cloud storage site,
then utilizing the one or more APIs provided by the cloud storage site to encrypt the data file;
and
when the requested type of encryption method is not supported by the one or more APIs provided by the cloud storage site,
then performing:
downloading a copy of the data file from the cloud storage site;
content indexing data in the downloaded copy of the data file by creating or updating at least one index associated with the data file;
encrypting the downloaded copy of the data file to create an encrypted version of the data file;
and
sending the encrypted version of the data file to the cloud storage site via the one or more APIs to either—
overwrite the data file stored on the cloud storage site with the encrypted version of the data file, or
write the encrypted version of the data file to the cloud storage site and delete the data file stored on the cloud storage site.

14 more elements

At least one non-transitory computer-readable medium, carrying instructions, which when executed by at least one or more computing systems, performs a method of pruning files containing data, wherein each computing system includes a processor and memory, the method comprising:

receiving an indication to delete a first file, wherein the first file includes a first set of data, and
wherein the first file is stored at a cloud storage location;
determining, by the at least one or more computing systems, whether the first set of data references a second set of data included in a second file located at the cloud storage location;
when the first set of data references the second set of data, then:
causing to be deleted at the cloud storage location any references to the second set of data by the first set of data;
and
causing to be deleted at the cloud storage location the second file;
determining, by the at least one or more computing systems, whether the first set of data is referenced by at least a third set of data included in a third file at the cloud storage location;
and
when the first set of data is referenced by at least the third set of data, then:
deleting at the cloud storage location any references to the first set of data by the third set of data;
and
storing an indication to delete the first file at the cloud storage location.

10 more elements

A computer-readable medium, excluding a transitory propagating signal, that carries instructions, which when executed by at least one processor, utilize cloud storage resources to store at least a first portion of at least one data file within a network attached storage (NAS) device, wherein the NAS device includes a NAS file system and a non-volatile data store, and wherein the NAS device is communicatively coupled to access the cloud storage resources, comprising:

accessing calls to or from the NAS file system for reading of data from, or writing of data to, the non-volatile data store of the NAS device,
wherein the at least one data file consists of multiple data blocks,
wherein the non-volatile data store of the NAS device stores the multiple data blocks of the at least one data file;
wherein the NAS file system of the NAS device controls the reading of data from or the writing of data to the multiple data blocks of the at least one data file, and
wherein the accessing includes identifying individual blocks or groups of blocks within the multiple data blocks of the at least one data file that the NAS file system of the NAS device reads data from or writes data to;
based on the accessing, identifying a portion of the multiple data blocks of the at least one data file that satisfies a data storage criteria;
storing content of the at least one data file to a content index;
and
automatically transferring the identified portion of the multiple data blocks for storage by the cloud storage resources.
