NetWorker 19.7 Snapshot Management Integration Guide

Backup group resource migration

During the migration process, NetWorker creates resources to replace each Group resource, and then migrates the Group configuration attributes from the 8.2.x and earlier resources to the new NetWorker 19.7 resources.

Resource migration for group resources when Snapshot is enabled

The following table summarizes the Group attribute values that migrate to NetWorker 19.7 resources attributes, when the group is Snapshot enabled.

Table 1. Migration of Group attributesThis table provides details about migration of group attributes.
19.7 Resource type 19.7 Resource name Migration process overview Attribute values that are migrated from Group resource
Policy Backup One policy resource that is called Backup appears and contains all migrated information for all NetWorker group resources that back up file system. Not applicable
Protection Group Snapshot One protection group resource appears for all Snapshot policies.
Protection Group Name of the Group resource One Protection Group resource appears for each migrated Group resource. Each Protection Group contains the same client resources that were associated with the pre-19.7 group resource. Comment
Workflow Name of the Group resource One Workflow resource appears for each migrated Group resource. Each Workflow resource is associated with the Protection Group resource that was created for the migrated Group resource.
  • Autostart
  • Start Time
  • Next Start
  • Interval
  • Restart Window
  • End Time attribute value is set to Start Time+(Interval*(n-1))
If the Probe backup group attribute was enabled, the following values are migrated:
  • Probe Interval—To the Interval attribute
  • Probe Start Time—To the Start Time attribute
  • Probe End Time—To the End Time attribute
Probe Probe The Probe action resource appears when the Probe based group attribute was enabled in the pre-19.7 migrated group. Not applicable
Action—Snapshot backup Backup The Snapshot Backup action appears for a Group resource that has the Snapshot attribute enabled.
  • Parallelism
  • Retries
  • Retry delay
  • Success Threshold
  • Option attributes:
    • No save, Verbose, Estimate, Verify Synthetic Full, Revert to full when Synthetic Full fails
  • Schedule
  • Schedule Time
  • Retention policy
  • Inactivity Timeout
  • Soft Runtime Limit—To Soft Limit
  • Hard Runtime Limit—To Hard Limit
  • File Inactivity Threshold—To Inactivity Threshold
  • File Inactivity Alert Threshold—To Inactivity Alert Threshold
  • Min expiration = (1440/(backups per day/retain count))-10
  • If Retain snapshot=0, then Backup snapshots attribute is set to ALL
Action—Clone Clone The Clone action resource appears when the Clone attribute was enabled in the Group resource. Clone Pool—To the Destination Pool attribute
NOTE The NetWorker Updating from a Previous Release Guide provides details about resources that are migrated during the update process.

Considerations about migration

  1. A clone action is created for every backup action. The clone action moves snapshot data to media.
  2. A NetWorker 8.2.x snapshot policy resource that was configured for nth snapshot is not migrated to NetWorker 19.6, and a clone action is not created.

    For example, for a NetWorker 8.2.2 snapshot policy of 1-1-day-All resolves to take 1 snapshot, retain 1, expire snapshots every day, and rollover the data to the rollover device. After the migration a clone action is created to backup every snapshot. This means the rollover action in 8.2.x translates to a clone action in 9.2.x and later.

  3. Each backup action within snapshot policy is followed by a clone action. Clone actions have filtering options. Check whether filtering meets the backup requirements of NetWorker Snapshot Management.
