Methods, system and computer program product, the method comprising: from high level language code (HLLC), receiving a request for reading a data set from a tape onto an object storage connected over TCP/IP to a mainframe; from the HLLC, allocating a data set on a tape comprising information to be imported, the allocation being in a format of the stored data set record and associated with a JFCB, the tape is mounted in SL mode; updating the JFCB to BLP mode; reading from the tape VOL1 data, and for each stored file initiating by the HLLC: reading HDR1/2, content block-by-block; EOF1/2 of the file; organizing the VOL1, HDR1, HDR2, content, EOF1 and EOF2 in the object storage; and closing the tape, wherein said reading is performed without setting a JES of the mainframe to BLP mode, and said reading is performed without unmounting the tape after each file.

System and method for importing and exporting data between tapes to cloud storage

Methods, and computer program product for writing data sets to and from cloud storage for legacy mainframe applications. A call to a mount request issued by the operating system is intercepted. An exit call to prepare for dataset write is received from an OS open routine. At least one call to a Basic Sequential Access Method (BSAM) End of Block (EOB) write routine is intercepted. Subject to the at least one call to the BSAM EOB routine being associated with cloud storage, data chunks are sent in an asynchronous manner to cloud storage. A second exit call for finalizing writing of the data chunks to the cloud storage is received. A call to an unmount request is intercepted. As a result, data is written directly from the mainframe to the cloud storage without intermediate storage.

Writing and reading data sets to and from cloud storage for legacy mainframe applications

A computer-implemented method, system and computer program product, the method comprising: receiving a request for backing up data from a mainframe on a backup server implemented on an open system; issuing a call to data set services, the call associated with an exit function; receiving a callback to the exit function, the callback associated with a data set record; packing the data set record to obtain packed information; and transmitting the packed information over a network connection to the backup server for backing up the data, wherein no additional data is written to a persistent memory of the mainframe, and wherein no limitations exist on a number of mainframes connected to the mainframe, or on a number of mainframes simultaneously communicating with the backup server.

System and method for mainframe computers backup and restore

Methods, system and computer program product for backup and restore of mainframe computer, the method for backup comprising: receiving a request for backing up a mainframe volume associated with a mainframe computer, the mainframe volume operating in the Count Key Data (CKD) architecture, the mainframe volume having a volume serial number, referred to as a volume name; taking a snapshot of the volume, thereby creating an offline copy of the volume; generating a temporary name for the offline copy, the temporary name different from the volume name; reformatting the offline copy to change its name to the temporary name; storing in a repository at least the name and the temporary name; bringing the offline copy with the temporary name to an online state; and backing up the copy to an external storage.

System and method for backup and restore of offline disks in mainframe computers

Methods, system and computer program product for backup and restore mainframe data onto an object storage, the methods comprising a backup operation and a restore operation, the backup operation comprising: receiving a request for backing up a data set; splitting the data set into chunks, each chunk having a predetermined size; creating a mapping object; repeating for each chunk: allocating a sender thread to the chunk; transmitting using an object storage API, the chunk having the predetermined size as an object, to the object storage by the sender thread; and updating the mapping object with details of the chunk; subject to the data set being fully split and no more chunks to be transmitted, transmitting the mapping object to the object storage by the sender thread; and writing an identifier of the data set and meta data of the mapping object to a database.

System and method for mainframe computers backup and restore on object storage systems

A method, apparatus and computer program product, the method comprising: opening a storage volume associated with a mainframe computer executing z/OS operating system; obtaining access to a required area of the storage volume; receiving a call from a program programmed in a high level programming language and executed on the mainframe computer, to execute a user channel program, wherein the user channel program may refer to any location within the required area of the storage volume; and processing the user channel program to obtain channel command words and provide the channel command words to Execute Channel Program (EXCP).
