Systems and methods are disclosed for reconstructing a file hierarchy by scanning attributes of stored files. Stored files can have a file hierarchy that is maintained in a database stored on a storage device. The files can be stored as objects on the device using a flat file structure. The file database provides the file hierarchy. The systems and methods disclosed herein store information in file system extended attributes for individual storage files such that the database can be reconstructed by scanning the storage files, using values in the extended attributes to recreate the hierarchical database.

Using file system extended attributes to update databases in hierarchical file systems

Systems and methods are disclosed for managing access between a data storage server and a client that are on the same local network. Access is managed using a cloud service that is remote from both the data storage server and the client requesting access to the server. The cloud-based management of local connections described herein simplifies the process of connecting to a data storage server on a local network from a client program or device. Connections are authorized based on the use of a local code. The local code is generated by the cloud service and includes a concatenation of a device identifier associated with the data storage server and a time-varying value, such as a timestamp.

Restricting access to a data storage system on a local network

Systems and methods are disclosed for managing partial-edit files for shared storage applications. A network-attached storage device (NAS) includes a non-volatile memory module, a network interface, and control circuitry configured to connect to a first client over a network connection using the network interface, receive, from the first client, a request to access a first portion of an existing file stored in the non-volatile memory module, create a first partial-edit file based on the existing file, receive modifications associated with the first portion of the existing file from the first client, modify the first partial-edit file according to the received modifications, and at least partially overwrite the existing file with at least a portion of the first partial-edit file.
