Abstract
A cloud-based write-once object store is configured to store inode-based data exported to the store from an enterprise file system. For each version of data (e.g., a file) exported to the store, there is a version of the inode corresponding to that data. As versions of the data are exported to the cloud, the system creates multiple versions of the inode. The set of inode versions corresponding to the versions of the file have a pointer associated therewith that specifies the latest version of the data associated with the inode. The inode versions in the set share the same pointer. The inode versions represent a revision history for the inode. For each inode version corresponding to a version of the data, information is received and stored in a new portion of the object store. The inode version for a file version comprises a list of data chunks for the file.
