The embodiments of the present application provide a file storage method and an electronic device. The file storage method includes: receiving a file to be stored; determining a currently stored folder with a lowest storage priority after the storage space of a disk exceeds a preset threshold; and selecting and deleting a file from the determined folder, and storing the file to be stored in the disk. The embodiments of the present application can improve the utilization value of the storage space of the disk and further improve the performances of the video server; since the files with higher priority are retained, when called, these files do not need to be regenerated or obtained from other servers, thereby improving the utilization rate of system resources and also enhancing the experience of a video requested by the user.

One example method includes refreshing secondary or repurposed copies. A copy data management system issues a single request that allows multiple secondary copies to be refreshed using an API server. The server allows a storage controller to read data from a single source and then write the data read from the source to multiple targets simultaneously, thereby refreshing multiple copies in parallel.

The present disclosure involves systems, software, and computer implemented methods for integrated data privacy services. An example method includes receiving, from a requesting application in a landscape that includes a set of multiple applications, a data subject information request for a data subject. A set of target applications is determined from the set of multiple applications. The data subject information request is provided to each target application in the set of target applications. A data subject information response is received from each of the target applications. Each data subject information response includes application data for the data subject that was retrieved by a respective target application in response to the data subject information request. The received data subject information responses are aggregated to generate an aggregated data subject information response. The aggregated data subject information response is provided to the requesting application in response to the data subject information request.

A client can allocate and reassociate unique identifiers to local content items associated with an account at a content management system, and use the unique identifiers to commit operations for the content items on the content management system. For example, a client can create a content item and determine the content item does not have an identifier from the content management system. The client obtains an identifier for the content item and asks the content management system to verify a uniqueness of the identifier. When the identifier is unique, the client adds a node corresponding to the content item to a local tree representing a state at the client of content items associated with the account, and uploads the content item with the identifier to the content management system. When the identifier is not unique, the client obtains a new identifier for the content item.

A method, system, and apparatus for managing a persistent query result set are disclosed. A resource manager is disclosed that receives a query from a client over a computer network. A computer database server is disclosed that executes the query and generates a result set based on and in response to the received query. An execution platform is disclosed that divides the result set into a plurality of chunks, wherein each chunk comprises a portion of the generated result set. The resource manager adds metadata to each of the plurality of chunks. A first chunk of the plurality of chunks comprises metadata pointing to the plurality of chunks. The resource manager delivers at least the first chunk of the plurality of chunks to the client in response to the query. The execution platform offloads the remaining plurality of chunks to cloud storage in parallel.

A distributed metadata management consistency assurance method, device, system and application are provided. A consistent node is deployed in a metadata cluster, the client sends a metadata update request to the consistent node, and the consistent node returns a metadata update success message to the client, sequentially records the metadata update request, marks old metadata as invalidated, and deletes the invalidation mark after asynchronous data synchronization with the metadata server. The client sends a metadata read operation to the metadata server. If an object of the metadata read operation is marked as invalidated, read data that has not yet completed asynchronous data synchronization is returned via the consistent node; otherwise, the read data is directly returned via the metadata server where the metadata is located. The disclosure can ensure consistency of distributed metadata management, and improve metadata access performance as far as possible while ensuring the consistency of metadata update.

A facility for snapshot space accounting for a storage system, such as a filesystem is disclosed. The facility enables users to quickly and easily determine the amount of storage space that would be released or recovered if a snapshot were to be purged. The facility may work in conjunction with, or as part of, a snapshot service. The facility maintains an expiration data structure and a count data structure and uses these data structures in implementing the disclosed snapshot space accounting techniques. The expiration data structure represents the life cycle of each snapshot element maintained by the facility while the count data structure represents, for pairs of snapshots, the size of the information stored in the snapshot data that expired and that spans the corresponding pair of snapshots.

Systems and methods for a multitenant computing platform. Original data is generated through operation of a computing platform system on behalf of an account of the computing platform system, and the original data is moderated according to a data retention policy set for the account. The moderated data is stored at the computing platform system. The computing platform system moderates the generated data by securing sensitive information of the generated data from access by the computing platform system, and providing operational information from the generated data. The operational information is accessible by the computing platform system during performance of system operations.

Systems and methods for enhancing file systems with file system objects that automatically expire. An example method may comprise: initiating a creation of a file system object in a file system; determining an expiration time for the file system object in view of an expiration policy; transmitting a request to create a certificate associated with the file system object, the request to create the certificate comprising the expiration time for the file system object to include in the certificate; and upon receiving the certificate associated with the file system object, causing the certificate to be stored with a plurality of certificates, wherein the certificate is to indicate whether the file system object is valid at a point in time.

Embodiments of the invention include systems, methods, and computer-program products for archive validation and retention parameter determination for documents. The system may generate or receive image documents. Utilizing image quality and data storage metrics the system may trigger the purging and/or retention of documents in image and/or paper form. Furthermore, the system may identify a duration of storage, location of storage, and the like. Upon retention, the system may continually monitor the documents and store metadata associated with the use of the retained documents. This monitoring may identify a period for purging the document, efficiently allowing for physical or server space availability.
