Abstract: A technology is described for a load time updatable driver. An example method may include presenting a driver interface to a computing instance launched in a computing service environment that enables the computing instance to interact with a virtualized resource, where the driver interface is an interface to driver functionality that enables the computing instance to interact with the virtualized resource via a hypervisor. Context information for the computing instance may be obtained and the context information may be used to identify a driver image for the virtualized resource that enables the computing instance to interact with the virtualized resource. The driver image for the virtualized resource may be obtained and the driver image may be loaded into computer memory and registered with the driver interface.

Abstract: Various systems and methods for selection of files for archival or deduplication operations are disclosed. For example, one method involves analyzing a plurality of files, where the analyzing is based on one or more archiving policies. The method involves determining whether a first file of the plurality of files is to be archived or deduplicated, where the determining is based at least on the analysis. The method also involves, in response to a determination to archive the first file, generating a request to archive the first file.

Abstract: Various systems and methods for detecting and resolving a reparse point conflict are disclosed. One method involves receiving a request to perform a file operation, where the file operation includes generation of a reparse point associated with the file. In response to receipt of the request, the method includes detecting a reparse point conflict, where detection of the reparse point conflict indicates a conflict between the reparse point and an existing reparse point. In response to detection of the reparse point conflict, the reparse point conflict is resolved.
