Method and system for expanding storage capacity using cloud storage systems
In some embodiments, a computer system may buffer, in a local storage buffer, data to be stored at the cloud and upload the data to the cloud storage from the local storage buffer. Upon receipt of an acknowledgement, from the cloud storage, that the data was successfully uploaded, the computer system may delete the data from the local storage buffer. The computer system may provide a ghost file representation of the uploaded data through the computer system, through which the data uploaded to the cloud storage may be accessed. In some embodiments, the computer system may access multiple cloud storage accounts, each corresponding to a file folder on the computer system, allowing the user to easily access different cloud storage accounts. The computer system may recover data that was deleted from either local persistent storage or the cloud storage.
1. One or more non-transitory machine-readable media storing instructions that, when executed by one or more processors of a computer system, cause the computer system to perform operations comprising:
obtaining, from a data source, data to be stored;
obtaining storage information that indicates that the obtained data should be stored using (i) both the local persistent storage and the cloud storage, (ii) the cloud storage but not the local persistent storage, or (iii) the local persistent storage but not the cloud storage; and
causing, based on the storage information, the obtained data to be stored using the local persistent storage, the cloud storage, or both the local persistent storage and the cloud storage such that (i) the obtained data is stored in association with a first file folder responsive to storage of the obtained data using both the local persistent storage and the cloud storage, (ii) the obtained data is stored in association with a second file folder responsive to storage of the obtained data using the cloud storage but not the local persistent storage, and (iii) the obtained data is stored in association with a third file folder responsive to storage of the obtained data using the local persistent storage but not the cloud storage;
responsive to obtaining the data from the data source, cause the obtained data stored in association with the first file folder and/or the second file folder to be stored in cloud storage;
determining whether an acknowledgement indicating that the obtained data has been successfully stored in the cloud storage is received from the cloud storage;
responsive to the determination that the acknowledgement is received, causing the obtained data to be removed from local persistent storage of the computer system; and
responsive to obtaining the data from the data source, causing a ghost file representation of the obtained data to be stored in the local persistent storage in lieu of storing the obtained data in the local persistent storage, wherein the ghost file representation is a local file representative of the obtained data and is smaller in size than a file comprising the obtained data and stored in the cloud storage.
2. The one or more non-transitory machine-readable media of claim 1 , wherein the storage of the ghost file representation in the local persistent storage is further responsive to a determination that the acknowledgement is received.
3. The one or more non-transitory machine-readable media of claim 2 , wherein the storage of the ghost file representation and the removal of the obtained data from the local persistent storage are based on a default measure programmed into the computer system that automatically causes storage of one or more corresponding ghost file representations and removal of cloud-uploaded data to which the one or more ghost file representations correspond upon receipt of acknowledgement indicating that the cloud-uploaded data has successfully been uploaded to the cloud storage.
4. A system comprising:
a computer system comprising local persistent storage and one or more processors programmed to execute one or more computer program instructions that, when executed, cause the computer system to:
obtain, from a data source, data to be stored;
obtain storage information that indicates that the obtained data should be stored using (i) both the local persistent storage and the cloud storage, (ii) the cloud storage but not the local persistent storage, or (iii) the local persistent storage but not the cloud storage; and
cause, based on the storage information, the obtained data to be stored using the local persistent storage, the cloud storage, or both the local persistent storage and the cloud storage such that (i) the obtained data is stored in association with a first file folder responsive to storage of the obtained data using both the local persistent storage and the cloud storage, (ii) the obtained data is stored in association with a second file folder responsive to storage of the obtained data using the cloud storage but not the local persistent storage, and (iii) the obtained data is stored in association with a third file folder responsive to storage of the obtained data using the local persistent storage but not the cloud storage;
responsive to obtaining the data from the data source, cause the obtained data stored in association with the first file folder and/or the second file folder to be stored in cloud storage;
determine whether an acknowledgement indicating that the obtained data has been successfully stored in the cloud storage is received from the cloud storage;
responsive to the determination that the acknowledgement is received, cause the obtained data to be removed from the local persistent storage; and
responsive to obtaining the data from the data source, cause a ghost file representation of the obtained data to be stored in the local persistent storage in lieu of storing the obtained data in the local persistent storage, wherein the ghost file representation is a local file representative of the obtained data and is smaller in size than a file comprising the obtained data and stored in the cloud storage.
