Part 4: Z/OS Backup and Restore

When a customer selects the Application Hosting service using a z/OS platform, procurement, installation, provisions and maintenance of software are included in the standard service.

The DTS is responsible for the backup and recovery of z/OS platform disk data on all shared systems. For disk data dedicated to a single customer, the backup and recovery responsibility may be owned by the customer or may be provided by DTS as an add-on component.

The DTS performs full volume backups every two weeks on the disk for the shared systems. Two copies of the backups are made. One copy remains on-site for recovery of deleted or corrupted data and the other copy stored off-site.

The DTS performs incremental backups daily on data that has changed or has been modified since the last backup. Only one copy is made and it is stored on-site for recovery of deleted or corrupted data.

The DTS does not provide any backup service for tape data. If the Customer wants tape data to be stored off-site they are responsible for backups of tape data and for requesting they be sent off-site.

The DTS creates a second copy of all VTS data, but the second copy is not considered a backup and the second copies are not sent off-site.
