Cloud Data Manager

V1.7 Online release notes

Major Features and Enhancements

  • You can use the new BACKDSN CLI command to perform on-demand, data-set level backup operations directly from the mainframe to any cloud - on-prem, hybrid or public. This functionality enables the execution of backup operations within scripts and JCLs, and simplifies storage administration.

    • The BACKDSN CLI command also includes NEWNAME, NEWDATE and NEWTIME parameters intended for simplifying migration from legacy backup software by allowing you to specify the same backup attributes as were stored by the original backup software.

    • In addition, the BACKDSN CLI command supports specifying a backup retention period. The life cycle management process is enhanced to delete backups whose retention period has expired.

  • A new DELBACK CLI command is used to delete data set backups created using the BACKDSN CLI command. Moreover, the command enables management of backups within scripts and JCLs, and simplifies storage administration using native Mainframe tools only.

  • The agent is enhanced to manage the number of concurrent system utilities, such as ADRDSSU (DFDSS), active at the same time and queue additional requests when no more instances can be run in parallel due to address space virtual storage constraints. This enhancement enables running multiple server policies in parallel and avoiding errors due to agent resources being unavailable.

  • Obsolete activity logs can now be deleted to free up space on the management server file system and remove unneeded information from the management interface. New server parameters control how long activity logs shall be retained after all resources have expired.

Performance improvements

  • The life cycle management process has been enhanced to parallelize backup and archive deletes providing a performance improvement of up to 90% in processing time for large data sets.

  • The restore and recall actions, whether invoked from CLI or from the management UI, have been enhanced to better utilize network throughput, providing up to 35% reduction in restore or recall times for large data sets.

Changed interfaces

  • The output of the LISTDSN CLI command has been changed to include an additional column indicating whether a data set backup was created using a CLI command or a policy run. Please refer to the CLI User Guide for more information.

Resolved issues

  • The management graphical user interface is updated to correctly handle data set delete actions performed on Write-Once-Read-Many (WORM) protected storage, such as Hitachi HCP WORM or AWS S3 ObjectLock, and avoid inconsistencies between the management server database and the object storage. Note that data immutability is only maintained by the object storage platform..

  • Blocked the erroneous ability to restore archived data sets, which led to pending ENQs being left standing in the Model9 agent address space.

  • Fixed discovery process not to skip storage groups and volume serial names containing the ‘$’ sign.

  • Fixed discovery process not to skip data sets residing on EAV volumes during an archive policy run, which marked the entire run as ‘Ended Error’.

  • Fixed an issue with listing objects using certain API calls when using Hitachi HCP object storage as the target storage.

  • The Policies page in the user interface has been enhanced to remember the page number, sort order and search filter for the duration of the session, whether editing or creating a new policy.
