Method and system for deletion handling for incremental file migration

摘要

Deletion handling for incremental file migration is described. Data is received from a storage device. A modified directory is identified in the data. A list is created of files associated with the modified directory in the source device. Any files associated with the modified directory that are absent from the list of files are deleted from a storage device.

主权项

1. A system for deletion handling for incremental file migration, the system comprising:
one or more processors; and a non-transitory computer readable medium storing a plurality of instructions, which when executed cause the one or more processors to: connect to a source device via a Network Data Management Protocol; initiate a Network Data Management Protocol incremental backup operation; receive data from the source device via the Network Data Management Protocol backup operation; identify modified directories in the data received from the source device via the Network Data Management Protocol; add the identified modified directories to a revised directory table; create a list of files, each file in the list being identified from modified directories added to the revised directory table; connect to a storage device via the Network Data Management Protocol; initiate a Network Data Management Protocol restore operation on the storage device; and delete, from the storage device, any files associated with at least one directory in the storage device corresponding to at least one of the identified modified directories that are absent from the created list of files via the Network Data Management Protocol restore operation.
