Abstract

A system and method for updating file archive bits in a data storage arrangement that performs snapshot backup operations is provided. The snapshot container is a read-write container that can receive archive bit backup write data from the file system and associated file system. Snapshot container files in which archive bits have been cleared, indicating a backup, are checked. These files' counterparts in the snapshotted container are located. Where the snapshotted files have had archive bits cleared, they are passed over. Where snapshotted files have set archive bits, the file data parameters for respective snapshot and snapshotted files are compared. If the file data parameters therebetween are the same, then the respective snapshotted file archive bit is cleared confirming backup status. Where the file data parameters differ, the set archive bit for the snapshotted file is retained, indicating un-backed-up current version in the snapshotted container.
