Abstract: Techniques manage application systems in an application environment. The application environment includes a first application system, a second application system and a third application system. First snapshot information of a first group of snapshots of the first application system is obtained, the first application system being in active state. Second snapshot information of a second group of snapshots of the second application system is obtained, the second application system being in standby state. It is determined whether the second application system and the third application system have a common snapshot based on the first snapshot information and the second snapshot information. Data is synchronized to the third application system depending on whether the second application system and the third application system have a common snapshot. Overheads required during data synchronization may be reduced as far as possible, and the efficiency of data synchronization may be improved.

Abstract: Techniques perform data synchronization. The techniques involve: in response to writing of data to a source storage array, determining whether a transmission link between the source storage array and a destination storage array is disconnected, the data being to be synchronized to the destination storage array; in response to determining that the transmission link is disconnected, accumulating in the source storage array the data written to the source storage array; in response to detecting that the transmission link is recovered, creating a snapshot for a storage unit associated with the data in the destination storage array; and in response to crashing of the source storage array during resynchronization of the data accumulated in the source storage array to the storage unit, restoring the storage unit in the destination storage array using the snapshot. Therefore, the storage space for the snapshot is greatly saved while disaster recovery is ensured.

Abstract: An assembly device includes a first device and a second device. The first device is provided with a mounting slot. The second device has a through hole penetrating vertically therethrough. A buckle member is correspondingly accommodated in the mounting slot, and includes a base, a connecting leg extending downward from the base, and an extending portion extending obliquely downward from the base. The mounting slot is provided with a position limiting portion to stop the buckle member from being detached downward from the mounting slot. The connecting leg is inserted downward into the through hole, and is provided with a buckle portion extending in a lateral direction. The extending portion and the buckle portion are located at the same side of the connecting leg. The second device upward abuts the extending portion to drive the buckle portion to swing outward from the through hole.

Abstract: A target data storage system performing a migration operation also responds to client requests by creating and maintaining a metadata cache for caching attributes of a user file as obtained from a source data storage system. A read-type client request is processed by (1) determining whether the metadata cache stores current attribute values, (2) if so, then satisfying the client request using the current values in the metadata cache, and (3) otherwise obtaining current attribute values from the source data storage system and satisfying the client request using the obtained current attribute values, and storing the current values in the metadata cache to be available for use in processing subsequent read-type client requests. A write-type client request is processed forwarding modified attribute values from the client request to the source data storage system for storage therein.

Abstract: A user I/O operation is processed in a file system of a target data storage system (DSS) performing a file system migration. The target DSS assesses a migration state of a user file of the user I/O operation, including (1) determining whether a metadata file storing migration state data for the user file has an already recovered record indicating the migration state of the file, (2) if so, then using the already recovered record to assess the migration state of the user file, and (3) otherwise (a) initiating an on-demand recovery to obtain an on-demand record for the user file, and (b) using the on-demand recovered record to assess the migration state. If the migration state indicates that the file has not yet been migrated, then the user I/O operation is redirected to a separate source DSS, and otherwise the user I/O operation is completed locally at the target DSS.

Abstract: Techniques perform data backup. Such techniques involve: in response to a first storage node to be switched to a second storage node, determining whether there is an ongoing data backup operation between the first storage node and a third storage node; and in response to the ongoing data backup operation between the first and third storage nodes, ceasing the data backup operation. The second storage node is used for backing up data of the first storage node in real time and the third storage node is used for backing up the data of the first storage node periodically. Accordingly, colliding operations can be prevented, system resource can be saved and processing efficiency can be improved.
