US 2026/0228336 A1 · DUPLICATE FILE SCANNING AND RESTORE DURING A NETWORK DATA MANAGEMENT PROTOCOL PROCESS

Abstract

The described technology is generally directed towards automatic virus scanning of a file while restoring the file. Virus scanning of a duplicate file of the file to be restored can be concurrently performed while the unavailable file is undergoing restoration. The unavailable file and the duplicate file can be located on one or more nodes of a node cluster forming a distributed file system. Upon determining that a first file is unavailable (e.g., as part of a file read operation), a second, duplicate copy can be identified based upon a common fingerprint of the first file and the second file. The first file can undergo restoration using a third file (backup copy of the first file) to generate a fourth, restored file. Hence, with the virus scan performed, the restored file can be immediately provided to a client.

Dependent claims

A digital data storage system, comprising:

at least one processor;
and
at least one memory coupled to the at least one processor and having instructions stored thereon, wherein, in response to the at least one processor executing the instructions, the instructions facilitate performance of operations, comprising:
receiving a command to perform an operation on a first file;
in response to determining that the first file is unavailable, identifying a second file, wherein second file is a duplicate of the first file;
performing a virus scan on the second file to determine whether the second file comprises any software virus;
and
in response to the second file being determined not to comprise a software virus, identifying the first file as being virus free.

5 more elements

A computer program product stored on a non-transitory computer-readable medium and comprising machine-executable instructions, wherein, in response to being executed, the machine-executable instructions cause a system to perform operations, comprising:

comparing a first digital fingerprint with a second digital fingerprint, wherein the first digital fingerprint is obtained from a first file located in a distributed file system, wherein the first file is undergoing a file restoration process, wherein the second digital fingerprint is generated from a second file, and wherein the second file is located in the distributed file system;
in response to determining the second digital fingerprint matches the first digital fingerprint, performing a virus scan operation on the second file to determine whether the second file comprises a software virus;
and
in response to the second file being determined not to comprise any software virus, identifying the first file as being free of any software virus.
