Abstract
The present disclosure relates to maintaining file system consistency on a mounted storage device in a computing system during system runtime. In one embodiment, a method generally includes locking access to a file stored in a file system on the mounted storage volume and metadata associated with the file. A computing system determines one or more properties associated with the file and examines the metadata for inconsistencies between the metadata and the determined properties. Upon determining that the metadata and the determined properties are consistent, the computing system generates a backup copy of the file, commits the backup copy to a backup data repository, and unlocks access to the file.
