Saveset Manager

Saveset Manager

The Save Set Manager for OpenVMS™ (SSMgr) is a layered software product that reduces the time used to create OpenVMS BACKUP save sets, while providing greater flexibility in save set management.

OpenVMS BACKUP users have had a rich set of options and a high level of data integrity available at the cost of greater down time during the backup operation.

SSMgr runs as a post-processor on save sets created by BACKUP, or other storage management software that conforms to the BACKUP save set structure. It allows some functions that are currently done online with BACKUP, such as checking the integrity of save sets, making multiple copies of a save set, and XOR or cyclic redundancy checking (CRC), to be done offline using SSMgr. SSMgr does not replace OpenVMS BACKUP for creating or restoring save sets.

SSMgr supports a DCL interface and all disk and tape technologies supported by OpenVMS systems.

Features

VSI Saveset manager provides the following benefits:

  • You can run OpenVMS BACKUP with fewer time-consuming data integrity options, such as /VERIFY, to complete the operation with minimal down time. Once you have the backup save set, you perform the validation and addition of data integrity features offline using SSMgr.
  • You can reduce the number of full backups in your backup cycle by substituting incremental backups and using the save set merge feature of the SSMgr.
  • Restore time is greatly reduced, because you can use SSMgr to merge incremental backups into image save sets to maintain a current image save set at all times. This process replaces the practice of using OpenVMS BACKUP to restore an image save set plus many incremental save sets.
  • SSMgr does not require access to any data outside of its input save sets to run, so it can be run on any OpenVMS system that can directly access those save sets or to which they can be moved.
  • You can transfer save sets between tape technologies.
  • The data integrity of SSMgr save sets is comparable to save sets created with other OpenVMS utilities using full data checking.
  • You gain additional flexibility in managing your save set files by using the SSMgr commands for save set validation, copy, and merge functions.
  • You can monitor the integrity of archived save sets to determine how badly the media has degraded over time, and you can use SSMgr to reconstruct and restore the save sets to fresh media.
  • You can create OpenVMS BACKUP Journal Files (.BJL) for previously created save sets.
  • You can create up to five copies of a save set simultaneously. SSMgr performs its operations on save sets that strictly conform to the OpenVMS BACKUP save set format for disk or tape devices. You can use save sets and journal files that have been created by SSMgr as input to OpenVMS BACKUP.
