Abstract: Methods, apparatus, and processor-readable storage media for supporting multiple operations in transaction logging for a cloud enabled file system are provided herein. An example computer-implemented method includes obtaining a plurality of file system operations to be performed on a cloud enabled file system; executing the plurality of file system operations as a single file system transaction; and maintaining a transaction log for the single transaction, the transaction log comprising information for one or more sub-transactions that were completed in conjunction with said executing, wherein the one or more sub-transactions correspond to at least a portion of the plurality of file system operations.

Abstract: A method comprises receiving an input requesting migration of one or more snapshots of a logical storage volume from a first cloud storage platform to a second cloud storage platform, and retrieving one or more first objects corresponding to the one or more snapshots from the first cloud storage platform. The one or more first objects are stored in a cache, and contents of the one or more first objects are sent to the second cloud storage platform for storage as one or more second objects.

Abstract: Methods, apparatus, and processor-readable storage media for efficient synchronization of a cloud enabled file system database during a snapshot restore operation are provided herein. An example computer-implemented method includes intercepting a user request to initiate a snapshot restore operation on a file system associated with a local storage system, wherein the file system comprises one or more stub files that are indicative of locations of cloud objects comprising files that were previously sent from the local storage system to a cloud storage platform; prior to the snapshot restore operation being performed, creating a current snapshot of the file system; obtaining an indication that the file system was successfully restored on the local storage system; and using the current snapshot to perform a synchronization operation, wherein the synchronization operation deletes one or more orphan cloud objects in the cloud storage platform that resulted from the snapshot restore operation.

Abstract: Methods, system, and non-transitory processor-readable storage medium for a policy proposal system are provided herein. An example method includes applying at least one policy to data stored on a storage system to identify matched data, where the matched data is data to be moved from the storage system to a secondary storage system. The policy proposal system identifies unmatched data stored on the storage system, where the unmatched data is data that is not identified as the data to be moved from the storage system to the secondary storage system. The policy proposal system trains a machine learning system with the matched data and the unmatched data. The policy proposal system predicts at least one new policy, where application of at least one new policy identifies at least a subset of the unmatched data to be moved from the storage system to the secondary storage system.

Abstract: Methods, apparatus, and processor-readable storage media for deleting orphan archived files from a storage array using a time-based decision algorithm are provided herein. An example computer-implemented method includes traversing a database of a local storage system to identify a record associated with a stub file, wherein the record is indicative of a time of a client operation, involving the stub file, on a file system of the local storage system; identifying a particular snapshot in a set of available snapshots of the file system; and providing an indication to a cloud storage platform to delete a cloud object corresponding to the stub file in response to determining that the time of the client operation occurred earlier than a snapshot time associated with the particular snapshot in the set.
